International travelers fully vaccinated against the coronavirus who have been barred from entering the United States during the pandemic will be able to enter the country on Nov. 8, according to a White House official, marking an end to restrictions that had walled off tourists and relatives seeking to visit their families.

The specific date for when the Biden administration would lift travel restrictions for those traveling by air or hoping to cross the land border was previously unclear. The administration last month said it would be implementing a new system in which fully vaccinated foreigners who show proof of a negative coronavirus test would be able to fly to the United States in early November.

Earlier this week, administration officials said those hoping to enter from Mexico or Canada who are fully vaccinated would be able to cross at the same time. But thousands around the world eager to organize their travel plans were still left wondering what specific date they would be able to enter.

The new travel system also comes with stringent requirements.

Unvaccinated foreigners will be broadly barred from entering the United States, although the White House official said there will be limited exemptions, including for young children.

Those who were never banned from traveling across the land borders, including commercial drivers and students, will also need to show proof of vaccination when crossing starting in January, giving them some time to adjust to the new rules, officials said.

Foreigners hoping to fly to the United States will need to show proof of vaccination before boarding and a negative coronavirus test within three days of entering.

Unvaccinated Americans traveling from overseas will need to test negative for the coronavirus one day before returning home and show proof that they have bought a test to take after arriving in the United States.
