Visa & Invitation Letter Information


Citizens of certain countries and territories need a visa to visit or transit to the United States. We invite all attendees to review their visa status now to determine if a visa or visa renewal is needed, and determine how to schedule an interview appointment, pay fees, and other vital instructions.

The processing times for visa applications vary depending on the visa office. Delegates should apply for their visa as soon as their participation in the meeting is confirmed. For details that apply specifically to your country please contact immediately your nearest Consulate or Embassy.

The following information is provided as a courtesy but is subject to change. Please contact the visa department of your home country.

Please check U.S. Visas on Travel.State.Gov to see if you will need a visa from your country of origin.
