Effective January 26, 2021, all international air passengers (ages 2 and above) will be required to obtain a negative COVID test result within three (3) days before their flight to the United States departs and provide written documentation of their viral test results or proof of having recovered from COVID-19. The airlines must confirm the negative test result for all passengers, or the documentation of recovery, before they board. If a passenger does not provide proof of a negative test or recovery, or chooses not to take a viral test, the airline must deny boarding to the passenger. Passengers are required to produce the test result or documentation of recovery to any U.S. government or public health official upon request.
It is recommended that travelers check on travel requirements as they are subject to change.
