Visa Information

Most Canadian citizens and many citizens from Visa Waiver Program countries can come to the United States (U.S.) without a visa if they meet certain requirements. All Visa Waiver Program travelers must present a machine-readable passport at the U.S. port of entry to enter the U.S. without a visa; otherwise a U.S. visa is required. See important information about additional digital photograph and e-passport requirements for VWP travelers. Other foreign citizens will need a nonimmigrant visa.

Currently, 36 countries participate in the Visa Waiver Program, as shown below:

Nonimmigrant visas are for international travelers (citizens of other countries), coming to the U.S. temporarily. The visa, placed in your passport when issued, allows you to travel to a U.S. port-of-entry (airport, for example) and request permission of the Department of Homeland Security (DHS), Customs and Border Protection immigration officer to enter the U.S. A visa does not guarantee entry into the U.S.
