No, the first guest worker program, called the Braceros Program, was put in place by Executive Order in 1942. As farm workers left to join the armed forces, farmers feared loss of crops and the Braceros program helped fill the gap with Mexican workers in selected areas. In 1952 the Immigration and Nationality Act established an H2 visa for temporary unskilled workers. In 1986 the current law established an H-2A visa for farm workers and an H2B visa for non-farm workers. Both provide for legal, temporary immigration for specific jobs such as seasonal harvests for farmers.
