Now this I'm not sure I agree with (and I'm one of the first to say that BsAs has gotten expensive!)
Assuming at 8300 take home salary and say 3000 going towards rent/expensas (remember, OP can rent an apt at local rates since the company will act as guarantia), 5300 is more than enough to live on for a single person - food, going out, etc.
Yes, OP won't save much money and yes, if OP has expenses/debt in dollars back home, not nearly enough but assuming she comes here with clean slate ) - I would be hard-pressed to think the OP would have to live a student lifestyle and not take cabs.
As for the rest of your points - I agree.
