The Trump administration’s crackdown on immigration and recent detention of travelers at international border crossings has prompted several countries to issue travel warnings about visiting the U.S.
Canada, Denmark, Finland, Germany and the United Kingdom have each separately issued U.S. travel advisories in recent weeks, focused on issues ranging from the restricted rights of transgendered people to the possibility that holders of valid visas or green cards could face interrogation and detention at the U.S. border.
Citizens of both Canada and Germany have recently been held for lengthy periods in U.S. immigration detention facilities, for example, and these traveler stories have been widely circulated on social media and in the press.
Canada’s travel advisory noted that the U.S. has begun enforcing long-neglected registration requirements for its citizens who stay in the U.S. for extended periods.
“Canadians and other foreign nationals visiting the United States for periods longer than 30 days must be registered with the United States Government,” the March 21 advisory notes. “Failure to comply with the registration requirement could result in penalties, fines, and misdemeanor prosecution.”
The Trump administration’s imposition of tariffs on Canada, along with calls to annex the U.S.’s northern neighbor and taunts about Canada being the “51st state,” have prompted a severe backlash in Canada, including calls for a U.S. travel boycott. Michigan tourism officials this week reported a 10-percent year-over-year drop-off in Canadian visitors since Trump took office, for example.
In February, a report from Tourism Economics said that Trump’s trade war and other policy changes could dampen enthusiasm for travel to the U.S. among Canadians, Mexicans and Europeans. The report predicted inbound travel to the U.S. will decline by 15.2 percent in 2025 compared to baseline projections, with inbound travel spending falling by 12.3 percent, amounting to a $22 billion annual loss.
The report also predicted that total U.S. travel spending, including both domestic and inbound travel, could be 4.1 percent lower than baseline expectations, amounting to a $72 billion reduction in travel expenditures.
***UPDATE: March 27, 2025***
According to a recent report by OAG, airline capacity between Canada and the U.S has been significantly reduced through Oct. 2025, with the most substantial cuts during the peak travel months of July and August. Despite airlines redirecting capacity to other markets, forward demand data reveals a more concerning trend: Future flight bookings between Canada and the U.S. have collapsed. Analysis of forward booking data from a major GDS supplier shows that bookings for the upcoming summer season are down by over 70 percent in every month through September. This sharp decline indicates that travelers are hesitant to make reservations, likely due to ongoing uncertainty surrounding the broader trade dispute.
