The U.S. Department of Homeland Security is proposing to end one way in which Canadian students enjoyed a special status. Under a rule change proposed on Wednesday in the Federal Register and likely to be adopted next year, Canadians coming to the United States to study or work would be required to be digitally fingerprinted and photographed. An official at the Department of Homeland Security, who spoke on condition of anonymity, said that if the rule change were approved, Canadian students who commuted to an American college would not be required to submit to fingerprinting and being photographed each time they crossed the border.
