Abstract: | The results of an investigation of the immigration of professionals to the United States are presented. The data concern a sample of professionals from 17 developing and developed countries who were immigrants in 1969. Both direct and indirect immigration are considered, and special attention is paid to the constraints on professional immigration and the adjustment of status imposed by immigration policies. The results suggest that the relative wage rate is more strongly related to the brain drain than is relative income and that more restrictive policies concerning labor certification would probably prove effective in reducing the student brain drain in the short term. |
