Residency Issue

I go to boarding school in VA, but my mom lives in NC and my dad lives in FL. I’m planning on (finally) getting my permit in Florida, which I think declares me as a resident of FL? But I’d prefer to apply from NC, seeing as how my house in NC is more rural and I have a better geographic advantage (I also went to school more recently there). Most applications I’ve seen ask for the high school location and then also place of residency. I’ve been writing in my VA boarding school and my NC address. Would I have to show my permit or anything or can I just prove that my mom lives in NC? Can I also still get in-state tuition in either NC or FL despite my permit?

I think residency is tied to where your parents live, not where you go to school. How long have your parents lived where they do?

Which parent claims you on their taxes as a dependent?
