The Chinese Exclusion Act was signed into law by President Chester A. Arthur in 1882.
It was one of the most significant restrictions on free immigration in the U.S. history, 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 ten years, but was renewed in 1892 with the Geary Act becoming 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 It was repealed by the Magnuson Act of 1943.
