Or, the only time the United States ever officially excluded an entire ethnic group by law. The Chinese Exclusion Act was passed in 1882. It was extended in 1892 by the Geary Act, which then became permanent in 1902. Any Chinese residents were required to acquire a certificate of residence ("Paper Sons"). The act was repealed 61 years later from its first introduction by the Magnuson Act in 1943, which still denied Chinese citizens a right to own properties or businesses, and limiting immigration to only 105 Chinese a year, until 1965 when the Immigration Act was passed. It wan't until the 1990 Immigration Act that a more flexible cap was introduced. It is should no surprise, then, that in 2020 the President of the United States still considers ethnic Chinese as a "virus."
