Starting Jan. 22, non-U.S. travelers who wish to enter the United States via ferry terminals or land ports of entry at the U.S.–Mexico or U.S.–Canada borders must be fully vaccinated against COVID-19 and provide related proof of vaccination, the U.S. Department of Homeland Security (DHS) announced.
The land borders had been closed to non-essential travel for 20 months amid the COVID-19 pandemic.
At the time, essential workers, such as truck drivers and nurses who were crossing land borders, were not required to be vaccinated for COVID-19.
"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," Secretary Alejandro Mayorkas said in a statement.
The requirement will not apply to U.S. citizens, permanent residents, or U.S. nationals.
Unlike air travelers, people crossing land borders or ferry terminals are not required to show proof of a recent negative COVID-19 test.
As of Jan. 22, the federal government has not been requiring people who have illegally crossed the border to take the COVID-19 vaccine.
