The H-1B visa allows U.S. companies to employ foreign workers in specialty occupations that require expertise in fields like IT, engineering, finance, and more. It’s an essential tool for businesses looking to bring top talent into the U.S. on a temporary basis. The main requirement is that the employer must offer a job to the foreign worker that requires specialized knowledge and skills. The job must also pay at least the prevailing wage for the particular occupation in the area of intended employment.
