strongly agree with this statement. Unless your parents are ok with covering all of it for you and you're very lucky and well off, it's not worth it for the loans you'll end up with at the end.
and in terms of getting in state residency - they make it a mother fucking miserable nightmare for you to attempt to do it. it's not something they take lightly, and it's very difficult to do. you have to completely commit to it, support yourself, pay all your own bills, not receive money from family or anything like that... it's extremely hard to do. My girlfriend at the time did it, but it required her taking off almost 2 years from school and honestly, it wasn't worth it.
