Thanks for the update. Yeah, an infopass in Virginia is a good idea. I do feel though that the right thing for the IO to have done was to send your file over to Virginia. Derivatives typically don't get interviewed under normal circumstances, and once the PA gets approved, all the derivatives automatically get approved, unless of course there's a background check issue.
I think what the IO said about requesting your visa now is BS, they cannot reserve visas for applicant. You will eventually get your visa of course, but I think it's going to take a bit longer since it's going to be your responsibility to co tact Boise and let them know after your wife has been approve. By the way, did you collect the IO's phone number?
