In the last four years, i have been attending a boarding school in California. However, my family lives in Michigan, so my permanent address is in Michigan. Just to clarify, this means that I would be an in-state resident at University of Michigan right? But for would the regional admissions officer assigned to me be the Michigan admissions officer or the California one. Because the Michigan one would probably not be familiar with the area I attend school?
Contact the California one and ask which one you should talk to.
