A.M.A. data are used to show the variable placement of foreign medical graduates among U. S. medical residency programs. These data show that FMGs trained in countries with high orders of economic and medical development (FMGDs) are placed in affiliated hospital residency programs and in preferred medical specialty residences at a three to one ratio. FMGs trained in developing countries (FMGUs) are placed in non-affiliated hospital residencies in less preferred specialties at a four to one ratio. This indicated non-homogeneity in the graduate medical education of FMGs is considered evidence of non-homogencity in the medical qualification of FMGDs and FMGUs, both before and after the completion of U. S. graduate medical education. The subjects of the medical brain drain, relevancy of training provided to FMGs, and the quality of patient care rendered by FMGs during their residency training are discussed on the basis that the FMGD and FMGU subpopulations are not homogeneous.
