Non-U.S. citizens need a visa to enter the United States to visit, work, live and connect (international transit).
For more information on entry and visa requirements, please visit the U.S. Department of State
U.S. or Canadian citizens, U.S. green card holders, legal permanent residents, ESTA and visa-waiver holders may use one of the self-service kiosks when arriving at HOU on international flights. All eligible foreign visitors must have entered the U.S. at least once prior.
The system is designed to expedite the processing of passengers arriving at HOU by allowing them to enter required data using touch-screen technology, as opposed to hand writing the information on a traditional card.
Passengers simply place their passport on the scanning pad located on the kiosk and then provide answers to a series of basic questions. That data is then sent electronically to one of the screening officers on duty, minimizing both the effort required from the passenger and the chance for mistaken information to enter the system.
APC is a free service and does not require pre-registration.
