Summary: A sudden, widespread farm labor shortage requiring the entry of large numbers of foreign workers is unlikely now or in the near future, although localized shortages could emerge for specific crops or geographic areas. Although many farm workers are not legally authorized to work in the United States, the Immigration and Naturalization Service's (INS) enforcement efforts are unlikely to significantly reduce the aggregate number of unauthorized farm workers. While comparatively few agricultural employers seek workers through the H-2A program, those that do are generally successful in obtaining workers. In 1997, GAO determined that poor information on H-2A program access and the involvement of many agencies in the program could result in redundant oversight and confuse employers that are considering participation and that the Department of Labor was not always processing applications in a timely manner. While Labor and INS have made progress in taking the steps GAO recommended to improve the program's operations, key changes remain to be implemented, particularly those that would permit Labor to assess the timeliness of its applications processing and to improve protections for domestic and H-2A agricultural workers.
