What?s the appeal of international students? Colleges say they want to increase the diversity of their campuses to help all students. While UW-Madison may be well-known enough to not need recruiting help, that?s not the case for, say, UW-Superior. But the motive isn?t all about diversity. It?s also about money. International students pay out-of-state tuition, which is significantly higher than in-state tuition. Again, colleges will say the more out-of-state students they get, the lower tuition costs in-state students. The ethics behind commission-based recruiting are cloudy.
