The H-1B visa is a temporary work visa for foreign workers in specialty jobs that usually need a bachelor's degree or more. This visa lets U.S. companies hire foreign talent in areas like IT, engineering, and healthcare. To apply, you need a job offer from a U.S. employer who will sponsor you. Typically, the H-1B visa is good for three years and can be extended. There’s a limit on how many are issued each year, and getting one can be tough since applicants are often chosen through a lottery system.
