The USA has updated testing requirements for air travellers to the USA, which must be implemented before departure. As of 6 December, air travellers two years of age and older, regardless of nationality or vaccination status, must present a negative viral test.
This test must not be older than 24 hours. Travellers must show the negative result to the airline before boarding their flight. This applies to all travellers – US citizens, permanent residents (LPRs) and foreign nationals.
Exemptions are considered on a very limited basis. For more information on exemptions and the requirement for a negative COVID-19 test or recovery from COVID-19, including the types of tests accepted for all airline passengers entering the United States, visit the CDC.
