What are the current CDC requirements for international students and scholars seeking to enter the U.S.?

November 8, 2021 (updated December 3, 2021)

The CDC requires documentation of COVID-19 vaccination status, as well as a recent COVID-19 test result for all individuals entering the United States.

Vaccine Requirement

Beginning November 8, 2021, the U.S. government will require individuals seeking (re)entry to the U.S. on a temporary visa to be fully vaccinated against COVID-19. The CDC defines fully-vaccinated as 14-days since the day the approved COVID-19 vaccine series was completed. The CDC requires that the vaccine must be either:

  • authorized for emergency use or approved by the U.S. Food and Drug Administration, or
  • emergency use listed (EUL) or approved by the World Health Organization (WHO).

The list of eligible vaccines can be found on the CDC website. The previous CDC country-based entry restrictions will end after November 7, 2021.

There are very limited exceptions to this entry requirement. Please review the CDC website for all details concerning the exceptions.

Please note, entrants at land ports of entry and ferry terminals have slightly different rules.

COVID-19 Test Results

Effective December 6th, 2021, the CDC announced that regardless of vaccination status, individuals entering the U.S. must provide a negative COVID-19 test result taken 24 hours before boarding their flight.
