6 Passport Stamps That Can Complicate Future Travel

3. Iran's Stamp: A Barrier to the U.S. Visa Waiver Program

Travelers with an Iranian stamp in their passport may find themselves ineligible for the U.S. Visa Waiver Program (VWP), which allows citizens of certain countries to travel to the United States for tourism or business without a visa for stays of up to 90 days. In 2016, the U.S. introduced restrictions for travelers who have visited Iran, Iraq, Sudan, or Syria since March 2011. These individuals are required to apply for a visa through the regular process, which involves more scrutiny and longer processing times. Understanding these restrictions and planning accordingly can help travelers avoid unexpected travel disruptions.
