Mexican Immigration in the U.S.

Abstract

Until the mid 1920s, US immigration was largely unrestricted, but soon after the Congress passed a legislation it limited the entry from all regions except north-western Europe. It began in 1965 and has been continuing thereafter, and has passed a series of liberal laws, including the Immigration and Reform Act of 1986, under which 2.7 million illegal immigrants mostly from Mexico were given legal immigrant status.
