Northern wetbacks: Canadians, not Mexicans, represent largest number of visa overstays in the U.S., according to DHS

OTTAWA — U.S. President Donald Trump may want to build a wall along the Mexican border, but, in recent years, studies suggest the majority of unauthorized immigrants settling in the U.S. have arrived legally — not by crossing the border unlawfully.

And according to a new U.S. government report, the largest group of people who enter the U.S. legally and then overstay their welcome aren’t coming across the southern border at all. They’re coming from Canada.
