A total of 6,741 foreign physicians from 88 countries were reported as interns or residents during a survey of 1,242 hospitals of the United States during the year 1956-1957. Of these, 4,753 were residents, 1,988 were interns, 1,673 were working in the state of New York, 1,332 came from the Philippine Islands, and 908 were women. The gross totals for four successive years beginning with 1953-1954 have been 2,920; 5,036; 6,033; and 6,741. This steady increase is matched by a steady increase in the number of hospitals reporting foreign residents and interns, but the proportions of physicians coming from various countries, their distribution among the various specialties, and also their distribution among the various states of the union have remained comparatively constant.
