As of January 22, 2022, the Department of Homeland Security (DHS) is requiring non-U.S. individuals seeking to enter the United States via land ports of entry and ferry terminals at the U.S.-Mexico and U.S.-Canada borders to be fully vaccinated for COVID-19 and provide related proof of vaccination. DHS said this was necessary as COVID-19 cases continue to rise nationwide.
The new restriction applies to non-U.S. individuals who are traveling for both essential and non-essential reasons. It does not apply to U.S. citizens, lawful permanent residents, or U.S. nationals.
The Biden administration previously ordered that noncitizen nonimmigrants be vaccinated against COVID-19 before entering the United States by air, except in limited circumstances.
