Most citizens or nationals of participating countries* can travel to the United States for tourism or business for stays of 90 days or less without obtaining a visa. Travelers must have a valid Electronic System for Travel Authorization (ESTA) approval prior to travel and meet all requirements explained below.

Tips for Successful Visa Application

• Complete the ANESTHESIOLOGY 2024  official letter of invitation
• 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.
