College admissions officials in the United States caution that it is too early to draw firm conclusions about overseas applications, because deadlines for applications are generally in January and February. But they are worried that Mr. Trump’s election as president could portend a drop in international candidates.

Canadian universities have already detected a postelection surge in interest from overseas.

“We have seen an increase in applications from the U.S. and from international students in the last week,” Jocelyne Younan, the director of global undergraduate recruitment at McGill University in Montreal, wrote in an email. “We’ve also seen an increase in students inquiring about McGill on social media.”

Traffic on a University of Toronto website for international applicants surged the day after the election, officials there said — and most of it came from Americans. “Visits to our recruitment website from the U.S. are typically around 1,000 a day,” said Ted Sargent, the university’s vice president, international. “On Nov. 9, that spiked to 10,000.”

On the same day, there was an increase in visitors from Britain and India, Mr. Sargent said. “Our positive message as a university, but also as a city and a country, definitely is about openness to people from around the world and a real inclusiveness,” he said.



A disruption in the flow of international students could be particularly worrisome for universities that balance their books with income from international students, who generally pay higher tuition.
