[Post-industrial migration to the United States: "extremes on the labor market"].


 Immigration in the United States since the New Immigration and Nationality Act of 1965-1968 is analyzed. The radical change in the countries of origin of migrants is noted, particularly the decline of European and increase of Asian migration. Changes in places of destination within the United States are also discussed. The author analyzes recent migration trends in terms of the effects of the North American post-industrial center on the periphery. It is noted that very highly qualified migrants from Asia and low-skilled laborers from the Americas are particularly affected. It is suggested that migration is caused both by push factors in the countries of origin and by pull factors exercised by U.S. business and military ventures.
