The United States today began implementing changes under the Visa Waiver Program Improvement and Terrorist Travel Prevention Act of 2015 (the Act). U.S. Customs and Border Protection (CBP) welcomes more than a million passengers arriving to the United States every day and is committed to facilitating legitimate travel while maintaining the highest standards of security and border protection. Under the Act, travelers in the following categories are no longer eligible to travel or be admitted to the United States under the Visa Waiver Program (VWP):
Nationals of VWP countries who have traveled to or been present in Iran, Iraq, Sudan, or Syria on or after March 1, 2011 (with limited exceptions for travel for diplomatic or military purposes in the service of a VWP country).
