Answer
We got similar case as yours. We live in Dallas, and our company applies everything at Vermont. Our 140 is approved from VSC, so we applied 485 in VSC in July this year, no problem. You can apply at VSC, there is no problem at all. And also you have a choice to apply at TSC (the slowest SC of all) too, which I know nobody prefer to do so. Stay back from TSC or you will be sucked up big time.
