A temporary visa issued to a foreign national. Generally, U.S. Consular Officers outside of the United States initially issue nonimmigrant visas. A visa does not guarantee admission into the United States, and an immigration inspector can deny entry if there is reason to believe that a particular individual is not eligible. The period of validity of a visa is not the same as the authorized period of temporary stay in the United States, which is indicated on the Form I-94 Arrival/Departure Record.
Foreign Service Form FS 257, introduced 1924, filed in Border arrival records until July, 1947. (Immigrant visas filed in Washington, DC, since 1924.)
Visa granted to a foreigner who does not intend to stay in the U.S. permanently.
