The aim of this paper is to estimate the social resource cost to the U. S. of being engaged in a world-wide foreign college student program. The second and third sections of the study present estimates of the value of resources "invested" in foreign students in the U. S. and in American students abroad. Part IV estimates the value of students not returning to their native countries after studies in the U. S. Finally, a balance sheet is constructed of the net cost of exchanges to the U. S., and this is brought into perspective with other economic magnitudes. A prima facie case is made for expanding the student programs.
