The H‑1b Visa USA is a non‑immigrant classification that lets U.S. employers hire foreign workers for specialty occupations requiring at least a bachelor’s degree or its equivalent. Each fiscal year, USCIS caps the number of new visas at 85,000—65,000 for general applicants plus 20,000 for those with U.S. advanced degrees. Applications are submitted through an annual lottery.
Beyond the numbers, the visa confers the right to work for the sponsoring employer for up to three years, renewable to six. Holders may travel in and out of the United States, but changing jobs typically requires a new petition, and dependents on H‑4 status face restrictions on employment. These mechanics shape both the appeal and the constraints of the program.
