Out of state College Student filing taxes

I am an out of state college student that goes to school and works in Minnesota. However, my state of residency is Illinois, its where I have my bank, driver's license, etc...I am confused whether I file a nonresident tax return for Minnesota or a resident tax return as I plan on staying in Minnesota for most all of my undergrad degree. Does Minnesota's 183 day rule come into play? I am so confused!
