Immigration into the United States has been shaped by legislation greatly restricting Chinese immigration through the Chinese Exclusion Acts beginning in 1882. These were a series of laws first passed in 1882 that restricted Chinese from entering the United States. They were not repealed until 1943. Until the 1880s, most immigrants to the United States were from northern and western Europe, but in the closing years of the 19th century and the opening ones of the 20th, immigration from southern and eastern Europe increased tremendously. In response, Congress in the 1920s passed legislation that restricted total immigration and favored immigration from western and northern Europe. In the 1960s, Congress removed the discriminatory national origins quota system, and legal immigration, especially from Latin America, Canada, and Asia, started to increase. By the closing years of the 20th century and the opening ones of the 21st, immigrants were primarily coming from Latin America and Asia. Illegal immigration remains a serious problem and has not been solved.
