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. The act followed the Angell Treaty of 1880, a set of revisions to the U.S. -- China Burlingame Treaty of 1868 that allowed the U.S. to suspend Chinese immigration. The act was initially intended to last for 10 years, but was renewed in 1892 with the Geary Act and made permanent in 1902. The Chinese Exclusion Act was the first law implemented to prevent a specific ethnic group from immigrating to the United States. It was repealed by the Magnuson Act on December 17, 1943.
