The US will open its land borders to fully vaccinated travelers

Beginning in November, travelers who have been fully vaccinated will be able cross the US's land border for the first time since March 2020.
The US announced that it will reopen its borders to Canada and Mexico. Both countries were closed to non-essential travel during the COVID-19 pandemic. Although no date has been announced, it is likely to occur sometime in November. Officials from the US have already stated that travelers who have been vaccinated could fly into the country beginning next month.

Alejandro N. Mayorka (US Secretary of Homeland Security) stated in a statement, that the decision was made following advice from the Centers for Disease Control and Prevention and other experts in public health.

Mayorkas stated that we will allow travelers from Mexico or Canada, who have been fully vaccinated against COVID-19, to enter the United States to travel for non-essential reasons. This will include visiting friends and family, as well as for tourism. Cross-border travel is a significant source of economic activity for our border communities as well as a benefit to the wider economy. We are happy to take steps to resume regular travel in safe and sustainable ways.

This new system was created to provide a uniform protocol for international visitors arriving by land, air, or ferry.
