i'm finishing up at sgu. a good number of my classmates were international students. there were quite a few from canada, botswana, nigeria, south africa, lebanon and the middle east, and the local caribbean islands- grenana, st. vincent, trinidad, etc. there were a few from england and other european countries, brazil, central america, etc. the majority obviously are from the US but from coast to coast. overall, it was a very interesting mix and made interacting with people from all over the world an additional educational experience.
i am not sure about the other schools but check out their individual website to get the breakdown. sgu is www.sgu.edu
