Some registrants from outside the U.S. will need to apply for a visa at the American Embassy, consulate, or other visa-issuing office in their country of origin. To obtain a visa, you will need a letter of invitation (see below), a valid passport, a photo ID and Form DS 156 (nonimmigrant visa application form). A visa is not required for visitors from countries participating in the Visa Waiver Program. Visit the USA Visa Website for specific information on how to apply for a visa.
