Answer 2

That was one. Another was to ban the admission of anyone from China. Another is to restrict the number of people who can enter the United States from any one country (it varied, depending on the country). It is any law that puts limits on the number of immigrants who can legally migrate to the U.S.A. based on race, nationality, or any other arbitrary reason.
