International Attendees
Attendees from outside the United States may require a visa to enter the country. The time frames for the visa application processes are difficult to predict with accuracy for any individual applicant and could vary significantly by country. Advance planning, 4-6 months in advance of the meeting, on the part of the traveler, is essential to receive a visa in time for proposed travel dates to the United States. The U.S. Department of State is the primary source for current visitor visa information.
Attendees from some countries may be eligible for the Visa Waiver Program/Electronic System for Travel Authorization (ESTA) Program.
