The United States is expanding the U.S. Visa Waiver Program, which enables citizens of participating countries to travel to the United States for tourism or business for up to 90 days without obtaining a visa. View Participating Countries.

Travelers from the 27 countries with visa waivers - New passports issued by the Visa Waiver Program countries on or after Oct. 26, 2006 must be e-Passports that include an integrated computer chip. If your passport does not have this feature, you can still travel without a visa if it is a valid passport issued:

• Between Oct. 26, 2005 and Oct. 25, 2006, and includes a digital photograph, or
• Before Oct. 25, 2005, and includes a machine-readable area.

If you were issued a passport on or after Oct. 26, 2006, and it is not an e-Passport, you will need to obtain a visa waiver to attend the International Stroke Conference. View more information.
