We’re excited to welcome our international colleagues to the ASPEN 2026 Nutrition Science & Practice Conference! If you’re traveling from outside the United States, please start your travel planning now! Many visitors will need a U.S. visa, and the process—including scheduling an in-person interview at a U.S. embassy or consulate—can take time.
Determine whether you need a visa to enter the U.S. for ASPEN26. If you are from a country participating in the Visa Waiver Program (VWP), you may not need a visa, but you will still need to apply for an Electronic System for Travel Authorization (ESTA) before traveling.
Please visit our ASPEN26 International Attendees page for a step-by-step guide to the visa application process.
