Overview – what is the Visa Waiver Program? The Visa Waiver Program (VWP) enables nationals of certain countries to travel to the United States for tourism or business for stays of 90 days or less without obtaining a visa. The program was established in 1986 with the objective of eliminating unnecessary barriers to travel, stimulating the tourism industry, and permitting the Department of State to focus consular resources in other areas. VWP eligible travelers may apply for a visa, if they prefer to do so. Not all countries participate in the VWP, and not all travelers from VWP countries are eligible to use the program. VWP travelers are screened prior to admission into the United States, and they are enrolled in the Department of Homeland Security’s US-VISIT program.
