H1-B

The H-1B visa is a non-immigrant visa in the United States that allows employers to temporarily employ foreign workers in specialty occupations. The visa requires a bachelor's degree or equivalent work experience and is typically valid for three years, extendable to six years, after which the visa holder can reapply. There are congressionally mandated caps limiting the number of H-1B visas issued each year, with 65,000 visas available for general employment and an additional 20,000 for individuals with master's degrees or higher from a US college or university.learn more on wikipedia
