Letters of Invitation

UNAA will issue letters of invitation to international registrants who need one. It is important to fill out the registration information carefully and correctly because names and addresses for letters of invitation will be taken directly from the registration form.

Individual Use Only

The invitation letter is for each individual's use only and is not transferable. The organizers of the UNAA conventions will not issue blanket, group or family letters. The letter is for registered international attendees and exhibitors/vendors only. Full registration costs and exhibition/vendor payment MUST be received by prior to invitation letter issuance.

Visa Wait Times

The requirements and amount of time needed to obtain a U.S. visa will vary from country to country. We recommend that you obtain your visa no later than 3 weeks from the event. Last-minute visa applications run the risk of not being approved in time for the event.

Travel Documents & Attendance Requirements

It is the responsibility of each individual traveler to ensure that he or she is correctly documented for travel prior to coming to the United States for the UNAA Convention events. It is expected that the invitee will cover all expenses including airfare, food, ground transportation, insurance and lodging during their visit to the U.S.
