Types of Visas
International attendees must obtain a B1 Business Visitor Visa to attend a scientific, educational, professional, or business convention/conference. Find out if you need a B1 Business Visitor Visa and how to get one.
If you’re from a Visa Waiver Program country, you must request authorization through the Electronic System for Travel Authorization (ESTA).
Visa Requirements & Timing
Visa requirements vary depending on the country from which you are applying. To help ensure your participation in The Liver Meeting® 2025, please review the visa requirements for travel to the United States as soon as possible. This includes required documents, the visa application process, the nearest U.S. Embassy or Consulate, estimated wait times, and application and processing fees.
Due to the potential of increased visa application reviews, global staffing shortages, and administrative delays, it is essential to apply for your visa well in advance—ideally at least six months before the event start date of November 7. We also recommend reviewing the interview wait times for the location where you will apply for a B-1 visa, if applicable.
