US Visas

It is imperative that authors and delegates allow sufficient time to obtain visas.

Information about United States visas can be found here. It is advisable to begin the application process as early as possible to avoid last minute problems. The time to obtain a visa can vary widely. An interview at a consulate may also be required.

The US Department of Homeland Security has implemented the Electronic System for Travel Authorization (ESTA). ESTA is a new, fully automated electronic system for screening passengers before they begin travel to the United States under the Visa Waiver Program (VWP). ESTA applications may be submitted at any time prior to travel to the United States, and VWP travelers are encouraged to apply for authorization as soon as they begin to plan a trip to the United States.

Please note that ESTA has become mandatory for all travelers from current Visa Waiver Program member countries.

Invitation Letters

Requests for invitation letters need to be received by October 22nd.

This year we are asking that those are requesting a visa letter to fill out the following Google Form , and we will contact you with a letter or further questions. If you do not hear back from us within two days, please send an email to the General Chair.
