International Travel

AFP welcomes all international attendees. Below is some important information to help facilitate your travel and attendance.

Passport and Visa Requirements

Passport Requirements

American citizens entering the U.S. must show a valid passport, U.S. passport card, a Trusted Traveler Program card (NEXUS, SENTRI, Global Entry or FAST), or an enhanced driver’s license. Citizens of Canada, Mexico, the Caribbean, and Bermuda must present a valid passport from their country to travel to the U.S. by air.

All travelers entering the United States from all other countries need a passport upon arrival (regardless of their country of citizenship).

  • Permanent residents and foreign nationals may also need a U.S. Visa. You must apply for a visa before you start your trip. There are several steps to apply for a visa. The order of these steps and how you complete them may vary by U.S. Embassy or Consulate. Please consult the instructions on the U.S. Embassy or Consulate website. Apply early! We suggest you begin the visa application process at least 90 days prior to your travel date.

Visa Waiver Program

International visitors who need a visa to travel to the U.S. must apply for one at an American embassy or consulate. The Visa Waiver Program lists the participating countries.

ESTA (Electronic System for Travel Authorization) Scams

International travelers who are seeking to travel to the United States under the Visa Waiver Program are now subject to security requirements and will be required to pay an administrative fee. Travelers should only use the official government site.
