NOTE: Visa applications should be made no later than 90 days prior to travel.

Tips for Successful Visa Application

  • Required documentation
  • Letter of invitation from AANA.
  • When possible, provide proof of professional scientific and/or educational status, society membership and/or meeting registration.
  • Visa applicants are expected to provide evidence that they intend to return to their country of residence. Therefore, applicants should provide proof of binding or sufficient ties to their home country or permanent residence abroad. Visa applications are more likely to be successful if done in the visitor's home country.
  • Applicants should present their entire trip itinerary, including travel to any countries other than the United States, at the time of their visa application.
  • All applicants must be able to qualify for a visa on their own merits under the requirements of the Immigration and Nationality Act.

The Visa Waiver Program (VWP)

Travelers must have a valid Electronic System for Travel Authorization (ESTA) approval prior to travel. If you prefer a visa in your passport, you may still apply for a visitor (B) visa.
