Visa Information for International Travelers

Do I Need A Visa?

NOTE: U.S. Visa information is subject to change. Please don't rely on this or any other unofficial web site for current U.S. government policies.

The sites and have information about obtaining a visa for those traveling to the United States. Both sites have links to websites for U.S. embassies and consulates worldwide. The embassy and consulate websites have very helpful information about procedures, timelines, communities served, required documentation, and fees.

If you are traveling to the United States for tourism or business for 90 days or less, you may be eligible to visit the US without a visa. For complete and updated information on requirements for this program, please see the US State Department's page on the Visa Waiver Program.

Also be aware that the U.S. Department of Homeland Security has recently enhanced its security requirements for international travelers who are citizens of countries covered by the Visa Waiver Program. Information about these requirements is available from the Electronic System for Travel Authorization web site. In particular, travelers are expected to apply at least 48 hours prior to departure. We also understand that you should have your hotel's street address handy when you go through U.S. Customs. You can find the addresses of the hotels on our Accommodations web page.
