Rules On Moving After Adoption

So, my husband is taking a job 3 hours away, in another state, and we're supposed to sign our "Intent to Adopt" in another week (fingers crossed) or so. Once we sign that, as I understand it, it will be sent to Richmond (capital) for SS#'s, name changes, etc. THEN once that comes back (hopefully in a month's time) we go into "waiting" for the judge to sign everything. My question is AFTER the judge signs... are we truly done? Could we move the next day? We obviously don't want to be apart, but this move is to benefit the girl's future anyway... so having a job in NC is the first step to getting out of VA. Any advice?
