Unless you are a citizen or lawful permanent resident of the U.S., an Electronic Travel Authorization (eTA) or a Visitor Visa is required to enter the United States. Applications are the responsibility of individual travelers/participants. For more information, please visit the U.S. Department of State.

Please note:
- Complete one request for each person requiring a letter of invitation.

Are You Prepared for Travel to The United States?
The U.S. government requires residents of many countries to obtain a temporary visa before entering the United States. The visa application process may have increased 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.
Visa and travel restrictions
If you have questions about visas and other travel restrictions, check with your local U.S. consulate or visit the U.S. Embassy and Consulate website.
Visa Waiver
A U.S. visa allows a foreign citizen to travel to a United States port of entry and request admission into the U.S. from a U.S. Immigration Inspector. Since September 11, 2001, visa applications have been subject to a greater degree of scrutiny than in the past. The timeframes for visa processing today are difficult to predict with accuracy for any individual applicant and could vary significantly by country. Advance planning on the part of travelers is essential to receive a visa in time for proposed travel dates to the United States.
