An H-1B visa is a non-immigrant visa that allows U.S. employers to temporarily employ foreign workers in specialty occupations. These occupations typically require specialized knowledge and at least a bachelor's degree or equivalent in a specific field. The visa is initially granted for three years, which can be extended up to six years, and holders have the "dual intent" option, meaning they can apply for permanent residency while on the visa. There is an annual cap on new H-1B visas, with a lottery system used if demand exceeds the cap. Employers must sponsor the visa applicant and comply with labor conditions to ensure U.S. workers are not adversely affected.
