what is h1b visa

The H-1B visa is a non-immigrant visa in the United States that allows U.S. employers to temporarily employ foreign workers in specialty occupations that typically require a bachelor's degree or equivalent specialized knowledge. It permits highly skilled workers to work in fields such as science, technology, engineering, and mathematics (STEM) among others. The visa is employer- sponsored, has an annual cap with a lottery system due to high demand, and initially grants a stay of up to three years, extendable up to six years or more under certain conditions. Although it is not a green card (permanent residency), it allows dual intent, meaning holders can apply for a green card while on the visa. The visa helps employers fill skill gaps and workers gain international work experience and a potential pathway to permanent residency.
