Have you already been accepted? Usually when you accept a non-resident seat you sign an agreement that you agree to pay non-resident tuition for the duration of vet school. There are exceptions for schools that allow you to change your residency status though.
If you’re not accepted yet, vet schools usually classify you based on your residency at the time of application. I was living in Georgia when I applied (but wasn’t originally from there), but to be considered for a resident seat I had to have been living in the state for 1+ years, have a GA license, and have been paying GA state taxes for a minimum of 1 year. That was at the time I hit submit on my application, not at the time of matriculation.
@sheltermed moved specifically to establish residency in a state with a vet school. So maybe she can chime in too
