Congrats, when did NVC exactly receive your P3 (how many days it took them to review the case?)
As for the fingerprints, if you are doing this as part of NSEERS, they really should not ask about anything in the way out. Even if they do, it is harm to tell them you are going for your interview.
BTW, what's nearest airport to Champlain?
thanks,
