H-2A and H-2B Visa Programs: Increased Protections Needed for Foreign Workers, Report to Congressional Committees [Reissued on May 30, 2017] [open pdf - 9MB]
"Tens of thousands of foreign nationals travel to the United States each year under the H-2A and H-2B visa programs. These programs are designed to fill a temporary need that U.S. workers are unavailable to fill. Employers may use third parties to recruit these workers and recruitment generally takes place outside the United States with limited federal oversight. GAO [Government Accountability Office] was mandated to study foreign labor recruitment. This report examines (1) the number of H-2A and H-2B workers who enter the country and the occupations they fill, (2) how U.S. employers recruit H-2A and H-2B workers and what abuse may occur in recruitment and employment, and (3) how well federal departments and agencies protect H- 2A and H-2B workers. To address these objectives GAO conducted site visits to Mexico (where many workers originate) and Florida and Texas (where many work). GAO also analyzed relevant data from five federal agencies for fiscal years 2009 through 2013 including data on employers' applications for foreign workers, visas issued, violations committed by employers, and services provided to exploited workers."
