More non-U.S. citizens will need to show proof of vaccination to cross into the United States starting Saturday.
When the nearly two-years of restrictions on nonessential travel ended along the U.S.-Mexico and Canadian borders in November, those who had been locked out had to show proof of vaccination to enter. But not those whose trips had been deemed essential during that time, like people crossing for work, school or medical purposes.
But now, that requirement will extend to them as well.
U.S. citizens and legal permanent residents returning to the United States are exempted, according to a recent releasefrom the Department of Homeland Security. Only vaccines with CDC or World Health Organization approval are accepted, which excludes some vaccines widely used in Mexico.
