A totally expected and long overdue Rule change for entry into the United States is coming into effect Jan 22, 2022
In a Press release from the DHS:
"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,” said Secretary Alejandro N. Mayorkas. “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.”
Covid 19 Testing is not required for entry via these methods.
