163 will not cut it. I am instate and it only got me waitlisted.
Nor will moving to VA for the summer before applying. To get instate residency, you must live there for 12 months minimum before you apply to the school. Similarly, if there is anything atypical about your application, they make you fill out a long form asking to be considered instate. Consider my situation. I lived in VA full time for 18 years, and left only to go to college. I returned each summer to live and work in the state. My parents still live there, my drivers license is from there, I vote there, and I pay taxes there. Still, I had to "apply" to be considered instate. They are very stringent about this, and specifically say they look to make sure you did not just move there to be considered instate, or for the purpose of attending school.
