International Invitation

International attendees may need a letter of “invitation” in order to obtain a visa to visit the United States. We strongly advise to start the visa application process as early as possible. Kindly note: the event organizers will not be able to contact or intervene with Embassy or Consulate offices on your behalf.

We encourage all visitors from foreign countries to contact the U.S. Embassy or Consulate near your location to determine how to apply and to estimate the time required for visa issuance.

We have no influence over the visa issuance process. We suggest that you begin the visa application process as early as possible to avoid unnecessary delays and possibly disappointment. You may find the following websites helpful:

All visitors registering from countries outside the United States are offered an invitation letter as part of the attendee badge registration process. Please visit our registration page and choose “register now” under Attendee Registration.
