The H-2B visa is a nonimmigrant program that permits employers in the United States to hire foreign workers to perform temporary nonagricultural services or labor on a one-time, seasonal, peakload, or intermittent basis. The program allows U.S. employers or U.S. agents who meet specific regulatory requirements to bring foreign nationals to the United States to fill temporary non-agricultural jobs. Employers are required to apply for a temporary labor certification from the United States Secretary of Labor, indicating that there are not sufficient U.S. workers available for the job. The H-2B program has a numerical cap, which was increased in 2017, and the visas are made available only to American businesses that attest they would likely suffer irreparable harm without the ability to employ all the H-2B workers requested in their original petition.
