This just in from the NY Times:
WASHINGTON — The Biden administration will lift travel restrictions at the land borders with Canada and Mexico starting in November for fully vaccinated travelers, reopening the door of the United States to tourists and separated families that had been sealed from the country during the pandemic.
Those who provide proof of vaccination and are looking to visit families or friends or shop in the United States will be allowed to enter next month, senior administration officials said, just weeks after President Biden lifted a similar sweeping ban on foreigners looking to travel to the country from overseas.
Unvaccinated travelers will continue to be barred from crossing the borders with Mexico or Canada.
The opening of the land borders 19 months after they closed will reconnect the United States with its neighbors.
