Trump wants to force fingerprinting for some Canadian visitors to U.S.

A new rule proposed by President Donald Trump's administration would force some Canadian visitors to submit to fingerprinting and other requirements if they want to cross into the U.S.

Bloomberg reported that the draft rule would apply to Canadians visiting the U.S. for over 30 days. The new requirements are set to take effect April 11.

Under the rule, affected Canadians "would have to create an account with US Citizenship and Immigration Services and schedule an appointment for fingerprinting as part of a background check," Bloomberg said.

During winter months, so-called Canadian snowbirds travel to warmer U.S. regions. Those people could face penalties if they do not follow the new rules.

The move comes amid an escalating trade war with Canada and an effort to crack down on immigration across the board. The previously unenforced Immigration and Nationality Act requires that "noncitizens over 14 years old must register and be fingerprinted within 30 days of entry and that all registered noncitizens over 18 years old must carry proof of registration at all times," according to the report.
