The main purpose of this legislation is to shift the management of the H-2A program, which allows agricultural employers to hire temporary foreign workers, from the Department of Labor to the Department of Agriculture. This change aims to streamline the process and improve the efficiency of the program, which is critical for the agricultural sector that relies on seasonal labor. Key provisions of the legislation include the amendment of existing laws to officially designate the Secretary of Agriculture as the administrator of the H-2A program.
