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 employ foreign workers in specialty occupations. It is the largest visa category in the United States in terms of guest worker numbers. 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 can reapply. Laws limit the number of H-1B visas that are issued each year. There exist congressionally mandated caps limiting the number of H-1B visas that can be issued each fiscal year, which is 65,000 visas, and an additional 20,000 set aside for those graduating with master’s degrees or higher from a U.S. college or university. An employer must sponsor individuals for the visa. USCIS estimates there are 583,420 foreign nationals on H-1B visas as of September 30, 2019.[1] The number of issued H-1B visas have quadrupled since the first year these visas were issued in 1991.[2] There were 206,002 initial and continuing H-1B visas issued in 2022.[3]
The H-1B visa has its roots in the H-1 visa of the Immigration and Nationality Act of 1952. The Immigration Act of 1990 split the H-1 visa into the H-1A (for nurses) and H-1B. The law capped H-1B visas at 65,000 each fiscal year and required employers to submit Labor Condition Applications. Additional modifications to H-1B rules were made by legislation in 1998, 2000, in 2003 for Singapore and Chile, in the H-1B Visa Reform Act of 2004, 2008, and 2009. United States Citizenship and Immigration Services has modified the rules in the years since then.
