Visa Requirements

Regarding Temporary Visitors to the U.S., the U.S. Department of State states the following:

Most Canadian citizens and many citizens from Visa Waiver Program countries can come to the U.S. without a visa if they meet certain requirements. Visa waiver travelers from ALL 27 Visa Waiver Program countries 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 the 10/26/05 digital photograph and 10/26/06 e-passport requirements for VWP travelers. Learn more. Other foreign citizens will need a nonimmigrant visa.

Nonimmigrant visas are for international travelers, (citizens of other countries), coming to the U.S. temporarily. This visa allows you to travel to a U.S. port-of-entry (airport, for example) and request permission of the Department of Homeland Security immigration inspector to enter the U.S. A visa does not guarantee entry into the United States.
