U.S. Nonimmigrant Visa
U.S. nonimmigrant visas are for those entering the United States for temporary purposes—tourism, study, employment, or business—rather than for permanent residency. They are divided into various categories by purpose of visit, such as tourism (B-2), student (F-1), and employment (H-1B), and come with a fixed period of stay, requiring the holder to depart on time or apply for an extension.
