^ hysteria is right; you can only choose one state on aadsas. however, there is one school that doesn't participate in the AADSAS (LSU), so conceivably it is possible to apply through AADSAS with one residency denoted and then apply to LSU choosing Louisiana residency. I think this is the only possible avenue for "dual residency."
Actually, I successfully did that this year. I was accepted to both Maryland and LSU and offered in-state tuition. ironically i didn't attend either because i got an even better offer to another school, but it's still a good example that it is possible.
here's how it happened:
i was a resident of a third state and attended a college there, getting in-state tuition. halfway through college my parents moved to Louisiana for jobs. my license expired so i got a new one there, theoretically becoming a Louisiana resident. when i graduated this past May, I moved to Maryland for a job during my year off. i registered my vehicle in Maryland, got a driver's license there, and registered to vote immediately on arriving (end of May), so it all would be in place for a year prior to matriculation.
At first, i didn't think i would get in-state status at either school, since i seemed to be halfway split - my driver's license, vehicle registration, voter registration, and apartment were all in maryland for only a month at the time of application, but my parent's claimed me as a dependent on their most recent tax returns in Louisiana. i applied through the aadsas as a maryland resident, and filled out the LSU application as a Louisiana resident. i didn't lie about anything on either the maryland residency form or the LSU application, was very honest, and told them i didn't know if i would be considered a resident of each respective state or not.
as i discovered, if residency isn't obvious and lies in a gray area (as it did for me in maryland and louisiana), the schools can decide for themselves. it's more rigid in maryland where the residency form has to go through the registrar, but at LSU it seemed as if it was totally up to the discretion of the dean of admissions.
anyway, i thought it was interesting that this managed to work out in such a way. back in november my father and i were lamenting that i wouldn't get residency in any state and how much that would suck. but it turned out to be quite the opposite. just thought it was an interesting case.
