International Travelers

We strongly advise you to check the current U.S. requirements. Official information on U.S. visa policies and procedures is available from the U.S. Department of State. (If traveling to the U.S. only for the AAAS Annual Meeting, the traveler falls under the short visit category).

Visa Waiver Program

If you intend to travel under the Visa Waiver Program, you need to complete the Electronic System for Travel Authorization (ESTA) registration applications or renewals, which requires a $14 payment by credit or debit card. Existing ESTA registrations remain valid through their expiration date.

If you need further help, visit our Visa Tip Sheet for step-by-step instructions, website addresses, and other information to make your visa application process successful.
