DHS Releases Details for Fully Vaccinated, Non-Citizen Travelers to Enter the U.S. at Land and Ferry Border Crossings

WASHINGTON — Today, the Department of Homeland Security (DHS) announced that non-citizen travelers who are fully vaccinated for COVID-19 and have appropriate documentation will be permitted to enter the United States via land ports of entry (POE) and ferry terminals starting on November 8, 2021. This shift eases long-standing restrictions on non-essential travel, consistent with public health guidance. U.S. Customs and Border Protection (CBP) will soon share additional information about the steps eligible travelers will need to take to enter the United States under the new rules.

“We are pleased to take another step toward easing travel restrictions at our borders in a manner that strengthens our economy and protects the health and safety of the American public,” said Secretary Alejandro N. Mayorkas . “We continue working closely with our international partners to sustainably implement new rules for resuming travel.”

Starting November 8, when arriving at a U.S. land POE or ferry terminal, non-citizen travelers should be prepared to (1) provide proof of COVID-19 vaccination, as outlined on the Centers for Disease Control (CDC) website; and (2) verbally attest to their reason for travel and COVID-19 vaccination status during a border inspection.

Any non-citizen attempting to enter the United States through illegal means or without appropriate documentation may be subject to expulsion or removal. Travelers arriving at a U.S. land POE or ferry terminal should be prepared to present any other relevant documents as requested by a CBP Officer. U.S. citizens are reminded to bring a Western Hemisphere Travel Initiative (WHTI) document, such as a valid U.S. passport, Trusted Traveler Program card, Enhanced Driver’s License, or Enhanced Tribal Card, when re-entering the country and be prepared to present a WHTI-compliant document if requested by a CBP Officer during a border inspection. To learn more about the updated requirements for travelers, click here .

To prevent the spread of COVID-19, CBP implemented temporary travel restrictions on March 20, 2020, which limited travel at land POEs along the U.S. northern and southern borders to essential travel, including travel for lawful trade, emergency response, and public health purposes. Individuals engaged in essential travel will not be required to be vaccinated for COVID-19 at this time. Starting in January 2022, however, all inbound foreign national travelers seeking to enter the United States via land POEs or ferry terminals – whether for essential or non-essential reasons – must be fully vaccinated for COVID-19 and provide related proof of vaccination.

As travel begins to resume, travel volumes and wait times are expected to increase. Travelers should plan for longer than normal wait times and long lines at U.S. land border crossings when planning their trip and are reminded to exercise patience.

To help reduce wait times and long lines, travelers can take advantage of innovative technology, such as facial biometrics and the CBP One™ mobile application, which serves as a single portal for individuals to access CBP mobile applications and services.

Executive Order on Promoting COVID- ⁠ 19 Safety in Domestic and International   Travel

By the authority vested in me as President by the Constitution and the laws of the United States of America, it is hereby ordered as follows: 

Section 1.  Policy.  Science-based public health measures are critical to preventing the spread of coronavirus disease 2019 (COVID-19) by travelers within the United States and those who enter the country from abroad.  The Centers for Disease Control and Prevention (CDC), the Surgeon General, and the National Institutes of Health have concluded that mask-wearing, physical distancing, appropriate ventilation, and timely testing can mitigate the risk of travelers spreading COVID-19.  Accordingly, to save lives and allow all Americans, including the millions of people employed in the transportation industry, to travel and work safely, it is the policy of my Administration to implement these public health measures consistent with CDC guidelines on public modes of transportation and at ports of entry to the United States.   

Sec. 2.  Immediate Action to Require Mask-Wearing on Certain Domestic Modes of Transportation.

(a)  Mask Requirement.   The Secretary of Labor, the Secretary of Health and Human Services (HHS), the Secretary of Transportation (including through the Administrator of the Federal Aviation Administration (FAA)), the Secretary of Homeland Security (including through the Administrator of the Transportation Security Administration (TSA) and the Commandant of the United States Coast Guard), and the heads of any other executive departments and agencies (agencies) that have relevant regulatory authority (heads of agencies) shall immediately take action, to the extent appropriate and consistent with applicable law, to require masks to be worn in compliance with CDC guidelines in or on: 

(i)    airports; 

(ii)   commercial aircraft; 

(iii)  trains; 

(iv)   public maritime vessels, including ferries; 

(v)    intercity bus services; and

(vi)   all forms of public transportation as defined in section 5302 of title 49, United States Code.

(b)  Consultation.   In implementing this section, the heads of agencies shall consult, as appropriate, with interested parties, including State, local, Tribal, and territorial officials; industry and union representatives from the transportation sector; and consumer representatives.

(c)  Exceptions.   The heads of agencies may make categorical or case-by-case exceptions to policies developed under this section, consistent with applicable law, to the extent that doing so is necessary or required by law.  If the heads of agencies do make exceptions, they shall require alternative and appropriate safeguards, and shall document all exceptions in writing.

(d)  Preemption.  To the extent permitted by applicable law, the heads of agencies shall ensure that any action taken to implement this section does not preempt State, local, Tribal, and territorial laws or rules imposing public health measures that are more protective of public health than those required by the heads of agencies. 

(e)  Coordination.  The Coordinator of the COVID-19 Response and Counselor to the President (COVID-19 Response Coordinator) shall coordinate the implementation of this section.  The heads of agencies shall update the COVID-19 Response Coordinator on their progress in implementing this section, including any categorical exceptions established under subsection (c) of this section, within 7 days of the date of this order and regularly thereafter.  The heads of agencies are encouraged to bring to the attention of the COVID-19 Response Coordinator any questions regarding the scope or implementation of this section.

Sec. 3.  Action to Implement Additional Public Health Measures for Domestic Travel. 

(a)  Recommendations.   The Secretary of Transportation (including through the Administrator of the FAA) and the Secretary of Homeland Security (including through the Administrator of the TSA and the Commandant of the Coast Guard), in consultation with the Director of CDC, shall promptly provide to the COVID-19 Response Coordinator recommendations concerning how their respective agencies may impose additional public health measures for domestic travel.

(b)  Consultation.   In implementing this section, the Secretary of Transportation and the Secretary of Homeland Security shall engage with interested parties, including State, local, Tribal, and territorial officials; industry and union representatives from the transportation sector; and consumer representatives.  

Sec. 4.  Support for State, Local, Tribal, and Territorial Authorities.  The COVID-19 Response Coordinator, in coordination with the Secretary of Transportation and the heads of any other relevant agencies, shall promptly identify and inform agencies of options to incentivize, support, and encourage widespread mask-wearing and physical distancing on public modes of transportation, consistent with CDC guidelines and applicable law.

Sec. 5.  International Travel. 

(a)  Policy.   It is the policy of my Administration that, to the extent feasible, travelers seeking to enter the United States from a foreign country shall be: 

(i)   required to produce proof of a recent negative COVID-19 test prior to entry; and 

(ii)  required to comply with other applicable CDC guidelines concerning international travel, including recommended periods of self-quarantine or self-isolation after entry into the United States.

(b)  Air Travel.  

(i)    The Secretary of HHS, including through the Director of CDC, and in coordination with the Secretary of Transportation (including through the Administrator of the FAA) and the Secretary of Homeland Security (including through the Administrator of the TSA), shall, within 14 days of the date of this order, assess the CDC order of January 12, 2021, regarding the requirement of a negative COVID-19 test result for airline passengers traveling into the United States, in light of subsection (a) of this section.  Based on such assessment, the Secretary of HHS and the Secretary of Homeland Security shall take any further appropriate regulatory action, to the extent feasible and consistent with CDC guidelines and applicable law.  Such assessment and regulatory action shall include consideration of: 

(A)  the timing and types of COVID-19 tests that should satisfy the negative test requirement, including consideration of additional testing immediately prior to departure; (B)  the proof of test results that travelers should be required to provide; (C)  the feasibility of implementing alternative and sufficiently protective public health measures, such as testing, self-quarantine, and self-isolation on arrival, for travelers entering the United States from countries where COVID-19 tests are inaccessible, particularly where such inaccessibility of tests would affect the ability of United States citizens and lawful permanent residents to return to the United States; and (D)  measures to prevent fraud.

(ii)   The Secretary of HHS, in coordination with the Secretary of Transportation (including through the Administrator of the FAA) and the Secretary of Homeland Security (including through the Administrator of the TSA), shall promptly provide to the President, through the COVID-19 Response Coordinator, a plan for how the Secretary and other Federal Government actors could implement the policy stated in subsection (a) of this section with respect to CDC-recommended periods of self-quarantine or self-isolation after a flight to the United States from a foreign country, as he deems appropriate and consistent with applicable law.  The plan shall identify agencies’ tools and mechanisms to assist travelers in complying with such policy.

(iii)  The Secretary of State, in consultation with the Secretary of HHS (including through the Director of CDC), the Secretary of Transportation (including through the Administrator of the FAA), and the Secretary of Homeland Security, shall seek to consult with foreign governments, the World Health Organization, the International Civil Aviation Organization, the International Air Transport Association, and any other relevant stakeholders to establish guidelines for public health measures associated with safe international travel, including on aircraft and at ports of entry.  Any such guidelines should address quarantine, testing, COVID-19 vaccination, follow-up testing and symptom-monitoring, air filtration requirements, environmental decontamination standards, and contact tracing.  

(c)  Land Travel.  The Secretary of State, in consultation with the Secretary of HHS, the Secretary of Transportation, the Secretary of Homeland Security, and the Director of CDC, shall immediately commence diplomatic outreach to the governments of Canada and Mexico regarding public health protocols for land ports of entry.  Based on this diplomatic engagement, within 14 days of the date of this order, the Secretary of HHS (including through the Director of CDC), the Secretary of Transportation, and the Secretary of Homeland Security shall submit to the President a plan to implement appropriate public health measures at land ports of entry.  The plan should implement CDC guidelines, consistent with applicable law, and take into account the operational considerations relevant to the different populations who enter the United States by land.

(d)  Sea Travel.  The Secretary of Homeland Security, through the Commandant of the Coast Guard and in consultation with the Secretary of HHS and the Director of CDC, shall, within 14 days of the date of this order, submit to the President a plan to implement appropriate public health measures at sea ports.  The plan should implement CDC guidelines, consistent with applicable law, and take into account operational considerations.  

(e)  International Certificates of Vaccination or Prophylaxis.  Consistent with applicable law, the Secretary of State, the Secretary of HHS, and the Secretary of Homeland Security (including through the Administrator of the TSA), in coordination with any relevant international organizations, shall assess the feasibility of linking COVID-19 vaccination to International Certificates of Vaccination or Prophylaxis (ICVP) and producing electronic versions of ICVPs.  

(f)  Coordination.  The COVID-19 Response Coordinator, in consultation with the Assistant to the President for National Security Affairs and the Assistant to the President for Domestic Policy, shall coordinate the implementation of this section.  The Secretary of State, the Secretary of HHS, the Secretary of Transportation, and the Secretary of Homeland Security shall update the COVID-19 Response Coordinator on their progress in implementing this section within 7 days of the date of this order and regularly thereafter.  The heads of all agencies are encouraged to bring to the attention of the COVID-19 Response Coordinator any questions regarding the scope or implementation of this section.

Sec. 6.  General Provisions.   (a)  Nothing in this order shall be construed to impair or otherwise affect:

(i)   the authority granted by law to an executive department or agency, or the head thereof; or

(ii)  the functions of the Director of the Office of Management and Budget relating to budgetary, administrative, or legislative proposals.

(b)  This order shall be implemented consistent with applicable law and subject to the availability of appropriations.

Coronavirus Updates

The u.s. lifts the pandemic travel ban and opens the doors to international visitors.

The Associated Press

Passengers walk through Salt Lake City International Airport, Oct. 27, 2020. More than a year and a half after COVID-19 concerns prompted the U.S. to close its borders to international travelers from countries including Brazil, China, India, South Africa, the U.K. and much of Europe, restrictions are shifting to focus on vaccine status.

Passengers walk through Salt Lake City International Airport, Oct. 27, 2020. More than a year and a half after COVID-19 concerns prompted the U.S. to close its borders to international travelers from countries including Brazil, China, India, South Africa, the U.K. and much of Europe, restrictions are shifting to focus on vaccine status.

The U.S. lifted restrictions Monday on travel from a long list of countries including Mexico, Canada and most of Europe, allowing tourists to make long-delayed trips and family members to reconnect with loved ones after more than a year and a half apart because of the pandemic.

Starting Monday, the U.S. is accepting fully vaccinated travelers at airports and land borders, doing away with a COVID-19 restriction that dates back to the Trump administration. The new rules allow air travel from previously restricted countries as long as the traveler has proof of vaccination and a negative COVID-19 test. Land travel from Mexico and Canada will require proof of vaccination but no test.

Airlines are expecting more travelers from Europe and elsewhere. Data from travel and analytics firm Cirium showed airlines are increasing flights between the United Kingdom and the U.S. by 21% this month over last month.

The change will have a profound effect on the borders with Mexico and Canada, where traveling back and forth was a way of life until the pandemic hit and the U.S. shut down nonessential travel.

Malls, restaurants and Main Street shops in U.S. border towns have been devastated by the lack of visitors from Mexico. On the boundary with Canada, cross-border hockey rivalries were community traditions until being upended by the pandemic. Churches that had members on both sides of the border are hoping to welcome parishioners they haven't seen during COVID-19 shutdown.

Loved ones have missed holidays, birthdays and funerals while nonessential air travel was barred, and they are now eager to reconnect.

River Robinson's American partner wasn't able to be in Canada for the birth of their baby boy 17 months ago because of pandemic-related border closures. She was thrilled to hear the U.S. is reopening its land crossings to vaccinated travelers.

"I'm planning to take my baby down for the American Thanksgiving," said Robinson, who lives in St. Thomas, Ontario. "If all goes smoothly at the border I'll plan on taking him down as much as I can. Is crazy to think he has a whole other side of the family he hasn't even met yet."

According to the Centers for Disease Control and Prevention, the U.S. will accept travelers who have been fully vaccinated with any of the vaccines approved for emergency use by the World Health Organization, not just those in use in the U.S. That means that the AstraZeneca vaccine, widely used in Canada, will be accepted.

For air travelers, the airlines are required to verify vaccine records and match them against ID, and if they don't, they could face fines of up to nearly $35,000 per violation. Airlines will also collect information about passengers for contact tracing efforts. There will be CDC workers spot-checking travelers for compliance in the U.S. At land borders, Customs and Border Protection agents will check vaccine proof.

The moves come as the U.S. has seen its COVID-19 outlook improve dramatically in recent weeks since the summer delta surge that pushed hospitals to the brink in many locations.

• COVID-19 travel advice

Lower your risk of COVID-19 as you travel for a safe and fun adventure.

Successful travel starts with being prepared for the unexpected. Coronavirus disease 2019, known as COVID-19, is now a part of standard travel planning.

As you choose a destination, travel group or event, add COVID-19 to the list of things to research. When packing for yourself or anyone you're caring for on the trip, consider COVID-19 prevention and testing.

No one wants to plan for the worst. But having a plan in case you catch the COVID-19 virus while traveling can save time if you need medical care.

To start, it can help to ask these basic questions as you make plans.

Am I up to date with my COVID-19 vaccine?

Staying up to date on your COVID-19 vaccine helps prevent serious illness, the need for hospital care and death due to COVID-19 .

If you need a vaccine, plan to get it at least a few weeks before you travel. Protection from the vaccine isn't immediate.

Am I, a travel companion or a person I live with at high risk of serious COVID-19 illness?

Many people with COVID-19 have no symptoms or mild illness. But for older adults and people of any age with certain medical conditions, COVID-19 can lead to the need for care in the hospital or death.

If you or those around you are at high risk of serious COVID-19 illness, take extra safety measures during or after travel.

Ask a healthcare professional if there are any specific actions you should take.

Does my destination, tour group or event need proof that I had a COVID-19 vaccine? Do I need to show proof of a negative COVID-19 test?

The country you travel to may not need to know your COVID-19 status. But you might need the information for other reasons.

Events, venues or tour groups might require proof that you are COVID-19 negative or are up to date on a COVID-19 vaccine. Check before you go so you have all the paperwork you need.

What's the plan if I get COVID-19 on my trip?

No one wants to get sick while traveling. But in case you do, it helps to know where you can get medical care and whether you'll be able to stay apart from others while you have symptoms.

Put together a COVID-19 kit with rapid home tests, masks, a thermometer, disinfectant wipes and hand sanitizer that contains at least 60% alcohol.

Before you leave, gather health information from your healthcare professional. Make sure it gives the details on any health conditions you're managing and medicine you take.

COVID-19 spread during travel

The virus that causes COVID-19 spreads mainly from person to person. When the virus is spreading, spending time indoors with a crowd of people raises your risk of catching it. The risk is higher if the indoor space has poor airflow.

The coronavirus is carried by a person's breath.

The virus spreads when a person with COVID-19 breathes, coughs, sneezes, sings or talks. The droplets or particles the infected person breathes out could possibly be breathed in by other people if they are close together or in areas with low airflow.

The virus carried by a person's breath can land directly on the face of a nearby person, after a sneeze or cough, for example. And people may touch a surface that has respiratory droplets and then touch their faces with hands that have the coronavirus on them.

Clean hands

While you travel, one way to lower your risk of COVID-19 is to clean your hands often.

Wash your hands after using the bathroom, before making food or eating, and after coughing, sneezing or blowing your nose. If you touch something that others regularly touch, such as an elevator button or a handrail, make sure to clean your hands afterward.

Also, try to avoid touching your eyes, nose or mouth.

Wearing a face mask is another way to lower your risk of COVID-19 .

Travel brings people together from areas where viruses may be spreading at higher levels. Masks can help slow the spread of respiratory viruses in general, including the COVID-19 virus.

Masks help the most in places with low airflow and where you are in close contact with other people. Also, masks can help if viruses are spreading at high levels in the places you travel to or through.

Masking is especially important if you or a companion have a high risk of serious COVID-19 illness. Choose the most protective mask that fits well and is comfortable.

Get the COVID-19 vaccine

As the virus that causes COVID-19 changes, COVID-19 vaccines are updated, so stay up to date with the recommended shots.

Know when the COVID-19 virus is spreading in your area

Check with health agencies in the area to see where the COVID-19 virus is spreading. Information about the spread of the virus may include the number of people in the hospital with COVID-19 or the number of people who test positive for the disease.

Keep some space around you

Choose outdoor activities and keep some distance between yourself and others. Poor airflow plus lots of people crowded together equals a higher chance you'll come in contact with the virus that causes COVID-19 .

If you can, try to avoid spending time with people who have COVID-19 symptoms or who are sick.

There will likely be times during travel when you don't have a choice about how close you are to others. Here are some tips for air travel, public transportation and lodging.

The risk of catching the virus that causes COVID-19 from air travel is thought to be low.

Air in the plane's cabin changes over quickly during the flight, being replaced every few minutes in some planes. Airplane air also is often filtered. So germs, including viruses, are trapped before they spread.

The air flowing down from vents above the seats in each row may help keep germs from spreading. Seats also may act as a barrier to germ spread on a plane, unless the person who is ill is sitting close to you.

You can help lower your risk by spreading out to keep distance between you and others when you can and cleaning your hands regularly.

Wearing a mask in crowded areas, such as security lines and bathrooms, can help protect you from COVID-19 and other respiratory illnesses.

Trains, buses and cars

Trains and buses may have good airflow and air filtering. But check before you travel so you know what to expect. When a vehicle is crowded, wear a face mask and take other steps, such as cleaning your hands.

Taxis and private cars used for ride-sharing may not have air filtering. But in most cases, rolling down a window could be an option to improve airflow.

Rental car companies may post their cleaning policies on the internet, or you can ask directly when you book the vehicle.

Hotels and other lodging

Cleaning protocols at hotels, vacation rentals and other lodging have largely returned to the way they were before the COVID-19 pandemic. If you have questions about how hosts or businesses protect guests, contact them directly. In public areas of hotels, take steps to lower your risk of catching the virus that causes COVID-19 .

Put safety first

Despite your planning, an illness may delay or cancel your trip. Stay home if you or anyone you're traveling with has:

• Symptoms of COVID-19 , such as fever or new loss of taste or smell.
• Taken a COVID-19 test and is waiting for results.
• Been diagnosed with COVID-19 .

Keep watch for serious symptoms of COVID-19 , such as trouble breathing or chest pain. If you or a person you're taking care of has symptoms that worry you, get help.

Once the fever is gone and symptoms are getting better, you may choose to travel. But for about five days after feeling better, you could still give others the virus that causes COVID-19 . Take extra actions to protect the people around you.

• Wear a mask.
• Keep your distance from others, especially when indoors.
• Clean your hands regularly.
• Keep the air flowing by turning on fans or opening windows when you can.

If you start to feel worse or your fever comes back, avoid being around others again until you feel better.

Stay flexible

With COVID-19 vaccinations, testing and treatment, events and travel are back to typical levels in many places. But as waves of COVID-19 outbreaks happen, it's important to stay flexible with your plans. Knowing whether the COVID-19 virus is spreading in your area or in places where you're traveling can help you make decisions about whether to go and what to put on your agenda.

• Can I wear a mask to the TSA checkpoint? Yes, CDC recommends travelers wear a mask throughout their travel journey. Travelers may be asked to adjust their mask for identity verification or remove it briefly if it alarms the security screening equipment.  

Can I request that TSA officers use new gloves during my screening? Yes. TSA officers are required to wear nitrile gloves when conducting screening duties and to change them following each pat-down and upon passenger request.

Can I bring my own filled water bottle through the TSA checkpoint? No, you are not permitted to bring your own filled water bottle that exceeds 3.4 ounces through the checkpoint. Many airports now offer touchless refilling stations past security that enable travelers to fill empty bottles and containers they bring from home. Consult the directory or ask a local official for locations in your departure airport.

Do I need to remove electronics from my carry-on bags?

Yes, you should plan to remove personal electronic devices larger than a cell phone from your carry-on bag and put them in a separate bin with nothing placed on or under them for security screening. (This does not apply to TSA PreCheck™ passengers.) Some airports are using new Computed Tomography (CT) technology that allows you to keep electronics in your carry-on luggage. Passengers will be advised on the use of CT scanners at the checkpoint and of any alternate procedures. 

Can TSA still open and go through my checked luggage? What precautions are being taken to reduce possible contamination? Yes, TSA may inspect your checked baggage during the screening process. If your property is physically inspected, TSA will place a notice of baggage inspection inside your bag. To reduce the likelihood of contamination, TSA officers are changing their gloves after each bag check and conducting enhanced sanitation of baggage screening areas.

What is the status of REAL ID enforcement in light of COVID-19?

The Department of Homeland Security has extended the deadline for REAL ID enforcement to May 7, 2025. Visit the REAL ID website for more information.

What happens if a passenger is unruly and does not comply with an airline’s policies and/or causes an inflight disruption or distraction for the crew?

Federal law prohibits physically assaulting or threatening to physically assault aircraft crew or anyone else on a civil aircraft. Passengers are subject to civil penalties for such misconduct, which can threaten the safety of the flight by disrupting or distracting cabin crew from their safety duties. Additionally, federal law provides for criminal fines and imprisonment of passengers who interfere with the performance of a crewmember’s duties by assaulting or intimidating that crewmember. 

What happens if there is a sick passenger on an international or domestic flight?

Under current federal regulations, pilots must report all onboard illnesses and deaths to CDC before arriving to a U.S. destination. According to CDC illness response protocols, if a sick traveler has a serious contagious disease during air travel, CDC works with local and state health departments and international public health agencies to contact exposed passengers and crew. Be sure to give the airline your current contact information when booking your ticket so you can be notified if you are exposed to a sick traveler on a flight. For more information, see the CDC web page Protecting Travelers’ Health from Airport to Community: Investigating Contagious Diseases on Flights .

Can flying on an airplane increase my risk of getting COVID-19? 

Most airlines and airports are enhancing their cleaning and passenger health protection protocols due to COVID-19, but air travel requires spending time in security lines and airport terminals, which can bring you in close contact with other people and frequently touched surfaces. This may increase your risk for exposure to the virus that causes COVID-19.

Most viruses and other germs do not spread easily on flights because of how air circulates and is filtered on airplanes (the air in an airplane cabin is fully renewed every 2-3 minutes, which is more frequent than most other locations in which people spend time). However, social distancing is difficult on flights, and you may have to sit near others, sometimes for hours. This is why CDC recommends the wearing of a face mask an important additional measure against exposing yourself or others to COVID-19.   It is important to follow basic guidance on wearing a face mask and frequently washing your hands or using hand sanitizer with at least 60% alcohol. For more information see CDC’s Travel During the COVID-19 Pandemic .

International Travel Requirements

• What should passengers provide to airlines to show they are fully vaccinated? Both U.S. citizens and foreign nationals who are fully vaccinated should travel with proof of their vaccination status to provide to their airline prior to departure to the United States. That proof of vaccination should be a paper or digital record issued by an official source and should include the traveler’s name and date of birth, as well as the vaccine product and date(s) of administration for all doses the traveler received.  
• How does the exemption from full vaccination for children work? Children under 18 are exempted from the vaccination requirement for foreign national travelers, given both the ineligibility of some younger children for vaccination, as well as the global variability in access to vaccination for older children who are eligible to be vaccinated.  
• How is the United States government determining exceptions to the vaccination requirement for foreign nationals?  The presidential proclamation and CDC order include a very limited set of exceptions from the vaccination requirement for foreign nationals. These include exceptions for children, certain COVID-19 vaccine clinical trial participants, those with rare medical contraindications to the vaccines, those who need to travel for emergency or humanitarian reasons, those who are traveling on non-tourist visas from countries with low-vaccine availability, members of the armed forces and their immediate families, airline crew, ship crew, and diplomats.

What’s Going on With the Testing Requirement for Travel?

The requirement to test for Covid before flying to the United States is hated by many travelers and the U.S. travel industry. But the government shows no sign of getting rid of it.

• Published May 19, 2022 Updated June 10, 2022

[Update: The United States will lift the virus testing mandate for international air travelers on June 12. Read more here .]

As countries, including Canada and Britain , have lifted their Covid testing requirements for vaccinated visitors in recent months, some Americans are irate that they still have to show a negative test to board a flight back to the United States.

Jason Miller, a 37-year-old software engineer who lives in Texas, is so frustrated with the rule that he recently sent letters to the White House and several lawmakers and began encouraging others to do the same. “I support the C.D.C., still wear a N95 mask when in crowds and when I travel,” he said. But, he no longer feels that the rule provides value, in large part because “the testing has not stopped variants from entering the country.”

Other travelers have posted similar comments on social media, and a good portion of the travel industry in the United States has made clear it feels the same way.

But they have gotten little satisfaction from the Biden administration and public health officials.

On May 6, Jen Psaki, then the White House press secretary, said she was “not aware of a timeline” for ending the testing requirement and that the administration would base its decision on a Centers for Disease Control and Prevention recommendation. As to what, specifically, the C.D.C. is using to determine whether testing is still necessary, an agency spokeswoman offered the vague explanation that it “is looking at different indicators” and “evaluating all guidance and orders based on the latest science and state of the pandemic.”

The obligatory test has not just created logistical hassles, it has fundamentally shifted the experience of traveling internationally, travelers say.

“It was always in the forefront of my mind,” said Danielle Bradbury, 42, who recently spent 12 days in Israel for her job developing medical devices while her husband cared for their two children back in Boston. “Every time I left the hotel, I asked myself, how much risk of not being able to get home am I putting myself in?”

Why was testing started in the first place?

In January 2021 , when the C.D.C. first instituted the rule that all U.S.-bound travelers 2 years and older had to show a negative test or proof of recovery before boarding a flight, the United States joined a sea of countries experimenting with different ways to slow the virus’s spread across borders. A statement from the State Department announcing the requirement played up the difficulty in getting a test abroad, suggesting that the rule also aimed to discourage Americans from traveling internationally. At that point fewer than 10 percent of Americans were vaccinated and case counts were rising, hitting a record of more than 300,000 new cases on Jan. 8.

Testing was not the first travel limitation the United States had deployed. In the winter of 2020, President Trump banned visitors from China, much of Europe , Brazil and Iran. When President Biden took office he layered the testing requirement on top of the travel bans. (He also expanded the ban to India .)

In late 2021, the United States pivoted away from country-specific bans and doubled down on testing, shortening the window from within three days of travel to one day, even for vaccinated Americans. By then it had become clear that vaccinated people could also spread the coronavirus . (Most unvaccinated visitors from abroad were prohibited from entering the country, even with testing.)

How effective has the policy been?

It depends how you define success, said Jeremy Goldhaber-Fiebert, a professor of health policy at Stanford University. If success was reducing the number of infected people who flew to the United States, he said, the testing requirement achieved that.

“It certainly prevented people who tested positive from getting on planes and it almost certainly prevented some amount of transmission on aircraft and in airports,” he said.

The exact number of infected people who were prevented from boarding planes is unknown, however, because no one tracks whether a passenger cancels a flight because of Covid. Most of the evidence is anecdotal; lots of people have stories about testing positive before flying home.

If success means keeping new variants out of the country, then it failed, said Dr. William Morice , the chair of lab medicine and pathology at the Mayo Clinic.

“The reality is that none of these measures have prevented the rapid global spread of any variant of concern,” he said.

But if success was not preventing the arrival of new variants, but instead delaying their arrival so that hospitals and authorities could be more prepared, then it may have worked. Mark Jit , a professor of vaccine epidemiology at the London School of Hygiene and Tropical Medicine, who has studied the effectiveness of travel requirements, said that this is what testing does well.

“Testing can prevent the peak from being reached so quickly,” he said.

Still, once a variant is already widespread in a country, he found, a travel test has little effect.

Why are many countries getting rid of testing requirements now?

Explanations from authorities include readiness to enter a new phase of the pandemic, high vaccination rates and a determination that new variants are manageable.

“The current variant is making people less ill and the number of people being admitted to intensive care is limited,” the Netherlands government said in a typical statement in March, as it ended travel testing, among other Covid-related recommendations.

What’s the argument for getting rid of the U.S. requirement?

The primary argument is that it’s not doing enough good to rationalize the hassle.

Dr. Tom Frieden, who was the C.D.C. director during the Ebola outbreak of 2014, was among those who made this point. “Between super-effective vaccinations that we have and Paxlovid, which is a super-effective treatment, Omicron is less deadly than flu most years and we don’t require people to test for flu before they get on a plane,” he said. “If a more dangerous variant emerges,” he noted, “that’s a very different situation.”

Others argue that it doesn’t make sense to inconvenience so many people for a system that’s full of holes. Antigen tests — one option for travelers to the United States — are notoriously unreliable in the early stage of infection, said Anne Wyllie, a microbiologist at the Yale School of Public Health. For this reason she called the requirement “hygiene theater.”

The testing requirement is not just annoying for travelers, it’s economically damaging, according to the U.S. Travel Association, a trade group. In a recent letter to Dr. Ashish K. Jha, the White House Covid coordinator, signed by more than 260 businesses, including airlines, cruise operators, casinos, tourism boards, Disney Parks and a zoo, the group said “the economic costs associated with maintaining the measure are significant.”

“Given the slow economic recovery of the business and international travel sectors, and in light of medical advancements and the improved public health metrics in the U.S., we encourage you to immediately remove the inbound testing requirement for vaccinated air travelers,” the group wrote.

A survey commissioned by the group found that 46 percent of international travelers would be more likely to visit the United States without the requirement. A similar survey by the Points Guy, a site that specializes in traveling with credit card points and miles, found that more than half of its participating readers would be more likely to travel abroad without the requirement.

What’s the argument for keeping the policy?

Meegan Zickus, who runs a Facebook group for people with weakened immune systems, said that testing has become more important since the mask requirement went away. Without a testing requirement, most travelers are not going to bother to test or stay home, even if they suspect that they are infected, she said.

“Judging by the past two years, the only way to protect others is some type of enforced testing,” she said, because “the moral compass points directly to self.”

Dr. Seema Yasmin , a public health doctor and the director of the Stanford Health Communication Initiative, echoed this point. “I would say that it can give a high level of reassurance when 75 percent of people are not wearing a mask and might even be coughing and sneezing loudly,” Dr. Yasmin said.

(Though airplane ventilation systems appear to significantly mitigate spread of the coronavirus, research suggests that people sitting within a few rows still pose a risk to one another.)

“Some testing is better than none,” said Nathaniel Hafer , a molecular biologist at the UMass Chan Medical School.

Many countries also use testing to incentivize vaccination by waiving the requirement for vaccinated people, said Meghan Benton , a research director at the Migration Policy Institute, which tracks travel requirements. The United States encourages vaccination in its own way by prohibiting most unvaccinated visitors from abroad from entering.

Could a lawsuit end testing the way it did the mask mandate?

Given that there are currently at least four pending lawsuits that challenge the international testing requirement, some wonder whether it might be struck down by a judge’s decision, as the requirement to wear a mask on airplanes and other forms of transport was in April.

Lawrence O. Gostin, a professor of global health law at Georgetown Law, does not think so. The C.D.C. can require testing from visitors entering the country from abroad because of the Public Health Service Act, which was explicitly created to prevent the introduction of dangerous infectious diseases in the United States, he said.

The rule, he said, “would be exceedingly difficult to successfully challenge in the courts, even for the most conservative judges.”

Covid cases are rising: When to rest and when to test, according to CDC and experts

Covid rates are still rising across most of the country, fueled by the highly contagious new variants of the virus —  KP.2 and KP.3 and LB.1. As of July 18, the highest levels of Covid are in the Western states, although there are no areas of the U.S. where rates are noticeably dropping, according to CDC wastewater data .

At least 21 states have very high levels of Covid , the data shows.

“You have a very, very transmissible variant, probably one of the most transmissible we’ve had,” said Dr. Peter Chin-Hong, a professor of medicine and infectious disease specialist at the University of California, San Francisco. “We have a lot of population immunity, but it doesn’t mean that there isn’t a lot of chaos.”

But people who test positive for Covid don’t need to isolate for five days, according to recent guidance from the Centers for Disease Control and Prevention.

This is the first major wave since the CDC updated its Covid guidance , said Katelyn Jetelina, an epidemiologist who tracks illnesses on her website, Your Local Epidemiologist . She recommends isolating until an at-home Covid test turns negative, which could be anywhere from three to 15 days.

Yet, with fewer people testing for Covid, experts say it’s more important than ever to pay attention to symptoms. Since March, the CDC’s guidance has matched advice for flu and other respiratory illnesses: Stay home when you’re sick, but you can return to work or school once you’re feeling better and you’ve been without fever for 24 hours. 

“The guidelines reflect a number of things, including the fact that we generally are overall shedding for less time now,” Bill Hanage, an associate director at the Center for Communicable Disease Dynamics at Harvard University, said. “And there’s more of a link between symptoms” and being contagious.

Because most Americans have already either had a version of the virus or have had several vaccines or boosters — or have had Covid and are also vaccinated —  it’s hard to separate Covid symptoms from other respiratory illnesses without testing. Right now, chances are, if you have upper respiratory symptoms — sniffles or congestion — or a cough, it could be Covid. 

According to the CDC, someone with Covid can go back to normal activities when symptoms have been getting better for at least 24 hours and no fever even without taking fever-reducing medication like acetaminophen or ibuprofen. 

Then for the next five days, take precautions such as wearing a mask in crowded indoor situations. 

The majority of viral spread happens when people are the sickest. 

“As the days go on, less virus spreads,” CDC Director Dr. Mandy Cohen said in an interview this year.

The CDC guidance is for the general public only, and does not include isolation guidelines in hospital settings, which is generally 10 days.

Covid symptoms

For people who have been through at least one Covid infection, or are up to date with the vaccines, symptoms often resemble a common cold or other respiratory illness.

Common Covid symptoms include:

• Fatigue and muscle aches
• Sore throat
• Nausea or diarrhea

There's not really a major sign that indicates Covid, doctors say, so the only way to know for sure is to take a test.

When should I test for Covid? How often?

The original guidance from the CDC was to test approximately five days after exposure because it took that long before the virus became detectable in the body. Now, with high levels of prior exposure, some people could feel symptoms a day or two after exposure, not because the virus is growing more quickly but because the immune system recognizes the virus and responds symptomatically, Michael Mina, an epidemiologist and former professor of immunology and infectious diseases at the Harvard T.H. Chan School of Public Health, said.

While many people aren't bothering to test now — tests aren't free anymore — Mina advises taking an at-home test on the third day after symptoms begin. If it's negative, test again the next day.

"If I had only two tests, that's where I'd stop testing," Mina said. "If positive, you don't need more tests. My best educated guess is, assume you're infectious for five days after testing positive."

In a prior study, Mina said that up to 50% of people were still infectious a week or eight days after symptoms begin and up to 20% were still contagious up to nine days later.

While people's immunity is doing a better job than a year ago, Mina believes many people could still be contagious five days after symptoms begin.

The experts recognize that most people will be ready to get back to work or school quickly after they feel better. What's most important is to be careful around people who may be immunocompromised or elderly.

"You don’t want people to be locking themselves in their bedrooms for five days," said Hanage. That said, "there are some contexts where you really would want to be more careful, including giving it to somebody who’s vulnerable for whatever reason."
