We urge you to begin the visa application process now. U.S. regulations require security checks for most visitor visa applications, resulting in a review process that may take three months or more. Attendees will be responsible for their own travel expenses including airfare, ground transportation, hotel, meals and travel insurance.

Please note that ASA cannot intervene with either U.S. embassies abroad or with the U.S. State Department on behalf of any participant.

Tips for Successful Visa Application
  • Letter of invitation from the meeting organizer.
  • 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.

Standard Visa Request Guideline

If you must apply for a temporary non-immigrant visa to attend the ANESTHESIOLOGY® 2016 annual meeting, you are advised to apply as soon as travel to the United States is contemplated and not later than 3-4 months in advance.

Visa Waiver Program (VWP) / Electronic System for Travel Authorization (ESTA)
The Visa Waiver Program (VWP) enables nationals of 37 participating countries to travel to the United States for tourism or business (visitor [B] visa purposes only) for stays of 90 days or less without obtaining a visa. The program was established to eliminate unnecessary barriers to travel, stimulating the tourism industry, and permitting the Department of State to focus consular resources in other areas. VWP eligible travelers may apply for a visa, if they prefer to do so. Nationals of VWP countries must meet eligibility requirements to travel without a visa on VWP, and therefore, some travelers from VWP countries are not eligible to use the program. VWP travelers are required to have a valid authorization through the Electronic System for Travel Authorization (ESTA) prior to travel, are screened at the port of entry into the United States, and are enrolled in the Department of Homeland Security’s US-VISIT program. 

Currently, 37 countries participate in the Visa Waiver Program, including:

      Andorra Hungary New Zealand
      Australia Iceland Norway
      Austria Ireland Portugal
      Belgium Italy San Marino
      Brunei Japan Singapore
      Czech Republic Latvia Slovakia
      Denmark Liechtenstein Slovenia
      Estonia Lithuania South Korea
      Finland Luxembourg Spain
      France Malta Sweden
      Germany Monaco Switzerland
