If you're concerned with money, I think you should forget it and go. Anyway, for MBA, most likely you have to cover expenses on your own.You care about money, you should've applied PHD not MBA. If you are considering visa, true that full loan would generate problems... you have to be very cautious.
I got 2 top 10 offer without money and one top 20 with tuition waive, I choose the later one. I think it depends on what kind of life do you want to live after graduation. To me, I am tired of consulting and want to enjoy life.
