In the early 1960s, Asian immigration to the United States was severely limited. The passage of the Immigration Act of 1965 expanded Asian immigration and ended a policy of racial discrimination and exclusion. Currently, over one third of the total immigrant population to the United States is from Asia, particularly China, Japan, Korea, the Philipines, and India. An analysis of Immigration and Naturalization Service data indicated that: (1) Asian immigration to the United States has increased approximately 600 percent since the early 1960s; (2) the majority of Asian immigrants are admitted under the preference system, especially the relative preference category; (3) the age and sex composition of the Asian immigrant population have remained relatively stable since the early 1960s, though trends vary among Asian groups; and (4) Asian immigrants are about twice as likely to be professional and technical workers than are immigrants from elsewhere.
