Temporary Visas

Temporary Visas


There are two categories of U.S. visas: immigrant and nonimmigrant.

The immigrant visas  are issued to foreign nationals who intend to live permanently in the U.S. The nonimmigrant visas  are issued to people with permanent residence outside the U.S. but who wish to be in the U.S. on a temporary basis – for tourism, medical treatment, business, temporary work or study.

Most aliens wish to enter the United States on a temporary basis for a specific purpose: visit, study, work, tourism, to receive medical treatments. These foreigners are required to obtain a nonimmigrant visa from a U.S. consular post. The type of visa needed is defined by immigration law, and relates to the purpose of your travel. The visa allows the foreign national 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. Be advised that a visa does not guarantee entry into the United States.

General requirements of non-immigrant or temporary visas include:

  • The purpose of the visit must be temporary;
  • The visitor must agree to depart at the end of his/her authorized stay or extension;
  • The visitor must be in possession of a valid passport;
  • A foreign residence must be maintained by the visitor, in most instances;
  • The visitor may be required to show proof of financial support;
  • The visitor must be admissible or have obtained a waiver for any ground of inadmissibility;
