International Attendees


 Most travelers visiting the United States temporarily must obtain a visa.  Please see U.S. State Department guidelines for type of visa required and instructions.   You can visit the  U.S. Embassy or Consulate web site directory to locate the U.S. Embassy or Consulate, nearest your residence abroad, where you will apply and be interviewed for your U.S. visa.  You may be eligible for a visa waiver based on your country of residence. Consult the list of countries  who participate in the Visa Waiver Program.
