Do all visitors to the U.S. require a visa in advance of their travel?
No. The Visa Waiver Program (VWP) allows the citizens of selected countries (currently 27) to travel to the United States for a maximum of 90 days for tourism or business without first obtaining a visa. On November 17, 2008, President Bush announced the inclusion of Czech Republic, Estonia, Latvia, Lithuania, Slovakia, Hungary, and South Korea. The Department of Homeland Security (DHS) announced that nationals of these countries will no longer need visas for tourist and business travel to the United States for up to 90 days, provided they possess a biometric passport and register online through the Electronic System for Travel Authorization (ESTA). Applicants under this program must possess an e-passport for entry.
