Abstract

This paper...[explores] the extent and causes of the decline in immigrant skills [in the United States] during the postwar period. Prior to 1965 immigration to the United States was guided by the national-origins quota system. This visa allocation system awarded visas to countries based on the representation of the national origin group in the U.S. population as of 1920. The 1965 Amendments abolished the national-origins formula thus redistributing visas across source countries and established a system where visas are mainly given to relatives of U.S. citizens or residents. The empirical analysis shows that a single factor the changing national origin mix of the immigrant flow is mainly responsible for the decline in immigrant skills. (EXCERPT)
