What is H1B Visa?

The H-1B is a visa in the United States under the Immigration and Nationality Act, section 101(a)(15)(H) that allows U.S. employers to temporarily employ foreign workers in specialty occupations. A specialty occupation requires the application of specialized knowledge and a bachelor's degree or the equivalent of work experience. The duration of stay is three years, extendable to six years; after which the visa holder may need to reapply. Laws limit the number of H-1B visas that are issued each year: 180,440 new and initial H-1B visas were issued in 2017. Employers must generally withhold Social Security and Medicare taxes from the wages paid to employees in H-1B status.
