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.
