The Magnuson Act passed during World War II, when China was a welcome ally to the United States. It limited Chinese immigrants to 105 visas per year selected by the government. That quota was supposedly determined by the Immigration Act of 1924, which set immigration from an allowed country at 2% of the number of people of that nationality who already lived in the United States in 1890. Chinese immigration later increased with the passage of the Immigration and Nationality Services Act of 1965, but was in fact set ten times lower.
