Help choose for international student

My son has been accepted to Michigan state university and university of Colorado boulder. He is an international student and has been admitted for business major to both schools. Any input of which school he should choose would be appreciated. Thank you very much.

Your affordability is particularly important, because few undergraduate schools provide (much/any) FA for internationals. Therefore, can you afford both?

@TopTier, yes we can afford both, and we do not seek for financial aid, looking forward to your input, thanks
