People traveling into the U.S. via land ports of entry and ferry terminals will be required to show proof of vaccination starting Saturday. 

The U.S. will require non-U.S. individuals entering through U.S.-Mexico and U.S.-Canada borders to provide proof of vaccination. 

The new restrictions apply to non-U.S. individuals who are traveling for both essential and nonessential reasons. 

They will not apply to U.S. citizens, lawful permanent residents or U.S. nationals, according to a news release from the Department of Homeland Security. 

“Starting on January 22, 2022, the Department of Homeland Security will require that non-U.S. individuals entering the United States via land ports of entry or ferry terminals along our Northern and Southern borders be fully vaccinated against COVID-19 and be prepared to show related proof of vaccination,” Secretary Alejandro N. Mayorkas said in the news release. “These updated travel requirements reflect the Biden-Harris Administration’s commitment to protecting public health while safely facilitating the cross-border trade and travel that is critical to our economy.”

The changes were first announced in October 2021.
