The H-1B visa is a classification of non-immigrant visa in the United States that allows U.S. employers to temporarily hire foreign workers in a "specialty occupation". A specialty occupation is defined as one requiring the theoretical and practical application of a body of highly specialized knowledge, and typically a bachelor's degree or higher in a specific field.
The modern H-1B program was established by the Immigration Act of 1990, building upon the earlier, broader H-1 visa category from the Immigration and Nationality Act of 1952. Congress created the H-1B to address a growing demand for highly skilled foreign workers, particularly in rapidly expanding sectors like technology and engineering. The 1990 Act introduced an annual numerical cap and stricter employer obligations, defining the problem it solved as a need for a structured mechanism to admit skilled foreign talent.
The mechanism involves a U.S. employer sponsoring the foreign worker and first filing a Labor Condition Application (LCA) with the Department of Labor to ensure the H-1B worker's employment will not adversely affect the wages or working conditions of U.S. workers. The employer then submits Form I-129 to the U.S. Citizenship and Immigration Services (USCIS). The annual cap for new visas is 65,000, with an additional 20,000 reserved for individuals who have earned a master's degree or higher from a U.S. institution. The visa is initially granted for up to three years and can be extended for a maximum total of six years, though further extensions are possible if the worker is sponsored for permanent residency (a Green Card).
The H-1B visa is closely connected to the H-4 visa, which is granted to the dependents (spouse and minor children) of the H-1B holder. It is also a critical pathway for international students who transition from Optional Practical Training (OPT) to long-term employment in the U.S..
Recently, the selection process has undergone a significant change: the purely random lottery system was replaced by a weighted selection process, effective for the FY 2027 cap season. This new rule, announced by the Department of Homeland Security (DHS) on December 23, 2025, favors allocating visas to higher-skilled and higher-paid candidates by ranking registrations based on the Department of Labor wage level for the offered position. This shift aims to prioritize higher-paid jobs while maintaining the overall annual cap numbers.
