I'm not a VA resident; I'm from TX so originally my assigned campus with the guaranteed admission was Auburn. I had to appeal to Dean Wilcox to stay in Virginia because I am married and my spouse has a job here doing research at Virginia Tech. I don't have children yet, still trying to figure out that timeline lol....
When appealing for a specific campus, they say you have to present a very strong reason with family, community, etc. I do think that the timing of getting in impacts your chance of success. The acceptances are sent out in December, March, or May depending on when you achieve all of the benchmarks. I was lucky enough to be accepted in December, and I think that might be why my appeal was granted - because they probably still had a ton of open seats. They emphasize that if your spouse has a "career type job", not just a retail position or something temporary, then that's a good basis for appeal. I believe that having children in school is also a good reason. Reasons that have been denied (to my knowledge) are having a sick extended family member and being part of a specific church, but again, I think those people also got in later than December.
Does that answer your question?
