December 4, 2021
Starting on December 6, air travelers aged two and older, regardless of nationality or vaccination status, are required to show documentation of a negative viral test result taken within one day of the flight’s departure to the United States before boarding. You must show your negative result to the airline before you board your flight. That includes all travelers – U.S. citizens, lawful permanent residents (LPRs), and foreign nationals.

If you recently recovered from COVID-19, you may instead travel with documentation of recovery from COVID-19 (i.e., your positive COVID-19 viral test result on a sample taken no more than 90 days before the flight’s departure from a foreign country, and a letter from a licensed healthcare provider or a public health official stating that you were cleared to travel).
Exemptions will be considered on an extremely limited basis. Please visit the CDC for more information about exemptions and the requirement for proof of negative COVID-19 test or recovery from COVID-19, including types of accepted tests for all air passengers arriving in the United States.
Check with your airlines, cruise lines, or travel operators regarding any updated information about your travel plans and/or restrictions, including potential COVID vaccine or testing requirements for countries you are transiting through.
