I don't have an identity document for my child with his prior name on it. What can I do?
An unexpired identity document with your child's new name can be accepted as long as we can establish his/her identity in our records.
Do you know about Social Security regulations, what if I need to change my name on my Social Security card?
You have to prove your legal name change. You'll need to provide any document that proves that you legally changed your name
