For FY2016, Congress exempted certain H-2B workers from the statutory cap. For the three past fiscal years, Congress has authorized the Department of Homeland Security (DHS) to make additional H-2B visas available subject to certain conditions. H-2B Nonagricultural Worker Visa

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. Among the major nonimmigrant visa categories is the "H" category for temporary workers. The H-2B program 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. Top H-2B occupations in recent years have included landscape laborer, groundskeeper, forest worker, housekeeper, and amusement park worker. Bringing workers into the United States under the H-2B program is a multiagency process involving the U.S. Department of Labor (DOL), DHS, and the Department of State (DOS). The program itself is administered by DHS's U.S. Citizenship and Immigration Services (USCIS) and DOL's Employment and Training Administration (ETA). DOL's Wage and Hour Division (WHD) also has certain concurrent enforcement responsibilities. The H-2B program currently operates under regulations issued by DHS in 2008 on H-2B requirements, DHS and DOL jointly in 2015 on H-2B employment, and DHS and DOL jointly in 2015 on H-2B wages. In order to grant labor certification to an employer, DOL must determine that (1) there are not sufficient U.S. workers who are qualified and available to perform the work, and (2) the employment of foreign workers will not adversely affect the wages and working conditions of U.S. workers who are similarly employed. After receiving labor certification, a prospective H-2B employer can submit an application, known as a petition, to DHS to bring in foreign workers. If the petition is approved, they can visit a U.S. embassy or consulate to apply for H-2B nonimmigrant visas from DOS. If the visa applications are approved, the workers are issued visas that they can use to apply for admission to the United States at a port of entry. H-2B workers can be accompanied by eligible spouses and children, who are issued H-4 visas. Numerical Limitations

The H-2B program is subject to an annual statutory numerical limit. Under the INA, as amended by the Immigration Act of 1990, the total number of aliens who may be issued H-2B visas or otherwise provided with H-2B nonimmigrant status in any fiscal year may not exceed 66,000. Certain categories of H-2B workers are exempt from the cap, including the following:
current H-2B workers seeking an extension of stay, change of employer, or change in the terms of employment; H-2B workers previously counted toward the cap in the same fiscal year; fish roe processors, fish roe technicians, and/or supervisors of fish roe processing; and H-2B workers performing labor in the U.S. territories of the Commonwealth of the Northern Mariana Islands (CNMI) and/or Guam until December 31, 2029. As noted, spouses and children who are accompanying H-2B workers are issued H-4 visas and, as such, are not counted against the H-2B cap. The provision, initially in effect for FY2005 and FY2006, exempted from the cap H-2B returning workers who had been counted against the cap in any one of the three prior fiscal years. Provision Authorizing Additional H-2B Visas

For FY2017 and FY2018, a different type of H-2B cap-related provision was enacted by the 115 th Congress. Implementation of H-2B Numerical Limits

USCIS is responsible for implementing numerical limits on temporary worker visas (including the H-2B visa), which it does at the petition receipt stage.
The Immigration and Nationality Act (INA) of 1952, as amended, enumerates categories of foreign nationals, 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, housekeeper, and amusement park worker.
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.
Bringing workers into the United States under the H-2B program is a multiagency process involving DOL, DHS, and the Department of State (DOS). A prospective H-2B employer must apply to DOL for labor certification. Approval of a labor certification application reflects a finding by DOL that there are not sufficient U.S. workers who are qualified and available to perform the work and that the employment of foreign workers will not adversely affect the wages and working conditions of U.S. workers who are similarly employed.
If granted labor certification, an employer can file a petition with DHS to bring in the approved number of H-2B workers. If the petition is approved, a foreign worker overseas who the employer wants to employ can go to a U.S. embassy or consulate to apply for an H-2B nonimmigrant visa from DOS. If the visa application is approved, the worker is issued a visa that he or she can use to apply for admission to the United States at a port of entry. H-2B workers can be accompanied by eligible spouses and children.
By law, the H-2B visa is subject to an annual numerical cap. Under the INA, the total number of individuals who may be issued H-2B visas or otherwise provided with H-2B nonimmigrant status in any fiscal year may not exceed 66,000. USCIS is responsible for implementing the H-2B cap, which it does at the petition receipt stage. Spouses and children accompanying H-2B workers are not counted against the H-2B cap. In addition, certain categories of H-2B workers are exempt from the cap. Among these categories are current H-2B workers who are seeking an extension of stay, change of employer, or change in the terms of their employment.
Employer demand for H-2B workers has varied over the years. In recent years, demand has exceeded supply, and special provisions have been enacted to make additional H-2B visas available. For FY2016, a temporary statutory provision exempted certain H-2B workers from the cap. It applied to H-2B workers who had been counted against the cap in any one of the three prior fiscal years and would be returning as H-2B workers in FY2016. For FY2017, FY2018, and FY2019, a different type of H-2B cap-related provision authorized DHS to issue additional H-2B visas (above the cap) subject to specified conditions.
