- VISA Information for IRMMW-THz 2026 Participants
When planning your trip to Salt Lake City, Utah, for IRMMW-THz 2026, it is important to review U.S. visa requirements based on your nationality and residency. The United States has specific entry rules, and the following guidelines will help you determine if you need a visa.
- Citizens of Visa Waiver Program (VWP) Countries
If you are a citizen of a country participating in the U.S. Visa Waiver Program (VWP), you can travel to the United States for tourism or business for up to 90 days without obtaining a visa, provided you have an approved ESTA (Electronic System for Travel Authorization) prior to boarding your flight. Countries in this program include most EU member states, South Korea, Japan, Australia, and others. For the complete and up-to-date list of participating countries, please see the official U.S. Department of State Visa Waiver Program page.
- Travelers Requiring a Visa
If your country is not part of the VWP, you must apply for a B-1/B-2 visitor visa at the nearest U.S. embassy or consulate in your country of residence. The application process may require an interview, biometric data collection, and supporting documentation, including proof of conference registration. Because visa processing times vary widely, we strongly recommend beginning your application several months in advance of your planned travel.
- Canadian Citizens
Citizens of Canada generally do not need a visa to enter the United States for short visits, although they must carry a valid passport and may be subject to routine inspection.
- Additional Information
Up-to-date details on visa requirements, waiting times for visa interviews, and application procedures can be found on the U.S. Department of State Bureau of Consular Affairs website.
