Due to heightened concerns over U.S. security, the Department of Homeland Security (DHS) has suspended the Immediate and Continuous Transit Program pending further investigation of its safety.

This program allowed non-resident aliens travelling to another country to make a stopover in the U.S. without needing a U.S. visa.

Now a resident of Mexico, for example, who is making a stopover at a New York airport while waiting for a connecting flight to London must present a valid non-immigrant United States visa upon arrival at the U.S. airport.

The ICT Program was also known as the Transit Without Visa Program (TWOV) and the International to International (ITI) Program.
