The main purpose of this legislation is to improve the wage structure for H-2A workers, who are temporary agricultural workers from other countries. The law aims to create a fairer system that distinguishes between workers based on their experience and skill levels. It also seeks to account for the value of housing provided to these workers, ensuring that their compensation reflects both their skills and living conditions. Key provisions of the law include the establishment of a two-tiered wage rate system for H-2A workers.
