U.S Citizens, U.S. Nationals, U.S. Lawful Permanent Residents, and Immigrants: Travel to and from the United States
- Do not travel internationally until you are fully vaccinated.
- Check your destination’s COVID-19 situation and travel requirements before traveling. Countries may have their own entry and exit requirements.
- When you travel to the United States by air, you are required to show a negative COVID-19 test result or documentation of recovery from COVID-19 before you board your flight.
- Wearing a mask over your nose and mouth is required in indoor areas of public transportation (including airplanes) traveling into, within, or out of the United States and indoors in U.S. transportation hubs (including airports).
If you are a non-U.S. citizen, non-U.S. immigrant (not a U.S. citizen, U.S. national, lawful permanent resident, or immigrant) traveling to the United States, visit Non-U.S. citizen Non-U.S. immigrants: Travel to the United States for requirements before boarding a flight to the United States.
Do not travel internationally until you are fully vaccinated. Getting vaccinated is still the best way to protect yourself from severe disease, slow the spread of COVID-19, and reduce the number of new variants. CDC encourages you get a COVID-19 vaccine booster dose if you are eligible. People who are not fully vaccinated should follow additional recommendations before, during, and after travel.
- 2 weeks (14 days) after your dose of an accepted single-dose vaccine
- 2 weeks (14 days) after your second dose of an accepted 2-dose series
- 2 weeks (14 days) after you received the full series of an accepted COVID-19 vaccine (not placebo) in a clinical trial
- 2 weeks (14 days) after you received 2 doses of any “mix-and-match” combination of accepted COVID-19 vaccines administered at least 17 days apart*
If you don’t meet these requirements, you are NOT considered fully vaccinated. Keep taking all precautions until you are fully vaccinated.
If you have a medical condition that weakens your immune system or are taking medication that weakens your immune system, you might NOT be fully protected even if you are fully vaccinated. Talk to your healthcare provider. Even after vaccination, you may need to continue taking all precautions.
* CDC has not recommended the use of mix-and-match COVID-19 vaccine primary series. However, such strategies are increasingly common in many countries outside of the United States. Therefore, for the purpose of interpreting vaccination records for travel to the United States, CDC will accept combinations of accepted COVID-19 vaccines.
If you haven’t been vaccinated yet, find a COVID-19 vaccine.
Make sure to plan ahead:
- Check the current COVID-19 situation at your destination.
- Follow all requirements of conveyance operators (such as airlines, cruise lines, buses) as well as any requirements at your destinationexternal icon, whether traveling by air, land, or sea, including mask wearing, proof of vaccination, testing, or quarantine. Requirements may differ from U.S. requirements. If you do not follow your destination’s requirements, you may be denied entry and required to return to the United States.
Do NOT travel if…
- You are sick.
- You tested positive for COVID-19 and haven’t ended isolation.
- After you end isolation, avoid travel until a full 10 days after your symptoms started or the date of your positive test if you had no symptoms.
- If you must travel on days 6 through 10, properly wear a well-fitting mask when you are around others for the entire duration of travel. If you are unable to wear a mask, you should not travel during days 6 through 10.
- You had close contact with a person with COVID-19 and haven’t ended quarantine.
- Get tested at least 5 days after your last close contact and make sure your test result is negative and you remain without symptoms before traveling. If you don’t get tested, delay travel until a full 10 days after your last close contact with a person with COVID-19.
- If you must travel before the 10 days are completed, properly wear a well-fitting mask when you are around others for the entire duration of travel during the 10 days. If you are unable to wear a mask, you should not travel during the 10 days.
- You are waiting for results of a COVID-19 test. If your test comes back positive while you are at your destination, you will need to isolate and postpone your return until it’s safe for you to end isolation. Your travel companions may need to quarantine.
- Wearing a mask over your nose and mouth is required in indoor areas of public transportation (including on airplanes, buses, trains, and other forms of public transportation) traveling into, within, or out of the United States and indoors in U.S. transportation hubs (including airports and stations). Travelers are not required to wear a mask in outdoor areas of a conveyance (like on open deck areas of a ferry or the uncovered top deck of a bus).

Testing – ALL Travelers
Before boarding a flight to the United States, you are required to show a negative COVID-19 test result taken no more than 1 day before travel. There is also an option for people who have documented recovery from COVID-19 in the past 90 days.
Children under 2 years old do not need to test.
Learn more about these requirements.
Contact Information – ALL Travelers
All air passengers to the United States will also be required to provide contact information to airlines before boarding flights to the United States. This strengthens a travel process already in place to rapidly identify and contact people in the U.S. who may have been exposed to a communicable disease, such as COVID-19. Access to travelers’ contact information will allow U.S. federal, state, and local health departments, and agencies to share appropriate health and public health information necessary to help keep the public safe.
You might have been exposed to COVID-19 on your travels, whether you traveled by air, land, or sea. You might feel well and not have any symptoms, but you can still be infected and spread the virus to others. For this reason, CDC recommends the following:
- Get tested with a COVID-19 viral test 3-5 days after travel.
- Self-monitor for COVID-19 symptoms; isolate and get tested if you develop symptoms.
- Follow all state and local recommendations or requirements after travel.
If You Are NOT Fully Vaccinated
In addition to the recommendations above
- Stay home and self-quarantine for a full 5 days after travel.
If You Recovered from COVID-19 Recently
If you recovered from a documented COVID-19 infection within the past 90 days (regardless of vaccination status), you do NOT need to get a test 3-5 days after travel. People can continue to test positive for up to 90 days after diagnosis and not be infectious to others. You also do not need to self-quarantine after travel. If you develop COVID-19 symptoms after travel, isolate and consult with a healthcare provider for testing recommendations.
