COVID Vaccine and Negative Test Requirement for Air & Land Travel to United States

Wednesday, January 5, 2022

There is a global requirement that "noncitizens who are nonimmigrants" (almost all visa categories except permanent residents) traveling to the United States by air from any part of the world establish that they are fully vaccinated, with some limited exceptions.

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.

Meaning of "fully vaccinated"

The CDC webpage Requirement for Proof of COVID-19 Vaccination for Air Passengers describes the meaning of "fully vaccinated" for this purpose:

You are considered fully vaccinated:

  • 2 weeks (14 days) after your dose of an accepted single-dose COVID-19 vaccine.
  • 2 weeks (14 days) after your second dose of an accepted 2-dose series COVID-19 vaccine; or
  • 2 weeks (14 days) after you received the full series of an “active” (not placebo) COVID-19 vaccine in the U.S.-based AstraZeneca or Novavax COVID-19 vaccine trials
  • 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.

*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."
