I am trying to decide between those four schools. I’m an international student and I have NO IDEA which one to pick. Please give me help taking into account business school opportunities, quality of life, recruitment, grad school admissions and employment rates.
“quality of life” depends on what you like - sunshine, big city, not so big city etc - the situations are all quite different.
Employment opportunities in the US for an international student are likely to be extremely limited for an international student irrespective of which one you choose. Is any of those particularly well known in your home country?
All will be fine for grad school assuming you get good grades.
