International Travel

For international attendees and exhibitors, this section features your Letter of Invitation, VISA application form, and links to locate your U.S. Embassy. If you are an international visitor, be reminded that the United States government has instituted new, tighter visa requirements for non-immigrant applicants. This may lengthen the amount of time it takes to process your VISA application. As a result, get an early jump on your visa application process by obtaining all the necessary documentation. Whether you are an attendee or exhibitor, there are several things you must do in advance to prepare for your trip to the United States. Please review the tabs below to get the information you need.

Visa Info

Apply at least 90 days prior to departure.

The U.S. government requires residents of many countries to obtain a temporary visa before entering the U.S. The visa application process may increase the length of time required to receive your visa, so it is very important to apply for your visa at least 90 days prior to your departure. Please read through and follow the procedures provided on the U.S. Department of State website.

Visa Waiver Program

The Visa Waiver Program (VWP) enables most citizens or nationals of participating countries to travel to the U.S. for tourism or business for a maximum of 90 days without obtaining a visa. Travelers must have a valid Electronic System for Travel Authorization (ESTA) approval prior to travel. In addition, travelers must meet all requirements listed on the VISA Waiver Program website.
