In VA they officer will know you have permit as soon as he runs your lic. It is part of your DL file which they pull once they have your lic.
Often in VA if you do not disclose but give them your lic the first thing they will ask upon return is are you armed.

My experience is thankfully very limited in this area but the one time I was stopped after getting my permit in VA, the officer asked no questions about weapons.
