New U.S. Government Entry Requirement for Visa Waiver Program (VWP) Countries
Effective 20 January 2011 citizens of Visa Waiver countries will be unable to enter the United States without Electronic System for Travel Authorization (ESTA) approval from the U.S. Government. VWP travelers who have not obtained approval through ESTA will be denied boarding on any air carrier destined for the United States. For more information, visit the VWP program website.
It is strongly recommended that international participants apply for visas at least 3 months prior to the Fall Meeting. Note: some consulates may have delays in scheduling visa interviews; therefore, applicants should first contact the consulate to determine the wait time for an interview. Additional information on business visas can be found at the DOS Business Visa Center website, and at the IVO website.
Also, if you are experiencing significant visa delays, please complete the visa survey, and a representative will provide feedback.
The U.S. Department of State maintains a comprehensive website containing information about traveling to the United States.
The National Academies Web site has additional information about visa-related issues and travel information for U.S. citizens and non-U.S. citizens.
