Qualifying for in-state tuition?

I currently live and go to school in Michigan, and have my whole life. I plan to attend college in North Carolina, specifically UNCG (that is, if they accept me), but if I can, I’d like to qualify for in-state tuition. Before actually going to college, I’d like to take a gap year to work in North Carolina and make money to pay for college. North Carolina state law says that you only need to live in North Carolina for a year to qualify for in-state tuition, but you have to be able to be able to provide proof of that (voter registration, evidence of legal residence in NC, etc.)
Would I have to apply to college after my gap year to qualify for in-state tuition then? Also, would living there for a year be enough? Honestly, any advice for this situation would be appreciated.

Until you are independent for financial aid, your residence is your parents. Will you not be asking for financial aid? Or will you be entirely self supporting and paying the full cost yourself? As a small child did you not consider the residency requirements and financial aid dependency status?

Colleges that consider that living and working for a year in the state qualifies you for in state tuition typically require you to move and live and work there for 12 months before you can apply to college as a resident.
Some universities consider that regardless of where you live and work, your residency is defined by your parents’ residency.

Hi–I work at UNCG and my son will be a freshman. The tuition for an out of state student is not that bad. My advice apply early decision and apply for scholarship!
