The U.S. Department of Homeland Security and the U.S. Department of State today suspended two programs that allow certain international air passengers to travel through the United States for transit purposes without first obtaining a visa. The programs, known as the Transit Without Visa program (TWOV) and the International-to-International transit program (ITI), have been suspended. This action does not affect U.S. citizens, Canadian citizens, or citizens from visa waiver countries.
