"The Immigration and Nationality Act (INA) of 1952, as amended, enumerates categories of aliens, known as nonimmigrants, who are admitted to the United States for a temporary period of time and a specific purpose. One of these nonimmigrant visa categories--known as the H-2B visa--is for temporary nonagricultural workers. The H-2B visa allows for the temporary admission of foreign workers to the United States to perform nonagricultural labor or services of a temporary nature if unemployed U.S. workers are not available. Common H-2B occupations include landscape laborer, amusement park worker, and housekeeper. The H-2B program is administered by the U.S. Department of Homeland Security's (DHS's) U.S. Citizenship and Immigration Services (USCIS) and the U.S. Department of Labor's (DOL's) Employment and Training Administration. DOL's Wage and Hour Division also has certain concurrent enforcement responsibilities. The H-2B program currently operates under regulations issued by DHS in 2008 on H-2B requirements, by DHS and DOL jointly in 2015 on H-2B employment, and by DHS and DOL jointly in 2015 on H-2B wages."
