In case I need to give you as an evidence of a legal name change, can I use my old document, with my previous name?
yes, that would work if you changed your name more than two years ago, four if you are under 18, and your ID is not enough to identify you in our records.
What can I do if DHS did not authorize me to work?
for that matter, we would change your name on our records but can't give you a corrected card.
