Visa Information

The United States welcomes visitors from around the world. Click here for the Visa Wizard provided as a guide to help foreign citizens understand which visa category might be appropriate for travel to the United States.


A citizen of a foreign country who seeks to enter the United States generally must first obtain a U.S. visa, which is placed in the traveler’s passport, a travel document issued by the traveler’s country of citizenship. Certain international travelers may be eligible to travel to the United States without a visa if they meet the requirements for visa-free travel.

To travel to the United States to attend THE IADR GENERAL SESSION & EXHIBITION you will need to obtain a Visitor (B-1) Visa which allows one to attend a scientific, educational, professional, or business convention or conference.

The Visa Waiver Program (VWP) allows citizens of participating countries to travel to the United States without a visa for stays of 90 days or less, when they meet all requirements explained below. Travelers must be eligible to use the VWP and have a valid Electronic System for Travel Authorization (ESTA) approval prior to travel.

If you are eligible to travel on the VWP, but prefer to have a visa in your passport, you may still apply for a visitor (B) visa.
