I recently moved and have misplaced his old papers, is that a problem?
An unexpired identity document in your child 's new name may be accepted, as long as we can properly establish your his identity in our records.
I don't have much in the way of official identity card for him, will a Walmart employee card work?
Yes, as long as the document submitted is current and not expired and show his name, date of birth or age and preferably a recent photograph of him.
