The Chinese Exclusion Act was a United States federal law signed by President Chester A. Arthur on May 6, 1882, prohibiting all immigration of Chinese laborers for 10 years. The law excluded merchants, teachers, students, travelers, and diplomats. Building on the earlier Page Act of 1875, which banned Chinese women from migrating to the United States, the Chinese Exclusion Act was the only law ever implemented to prevent all members of a specific ethnic or national group from immigrating to the United States.
