We'll need a proof of citizenship, for example.
Have you already established your child's U.S. citizenship with us?
No, I haven't.
Which documents could I use to prove my son's name change?
A court order approving the name change would be sufficient.
What if I am missing one of the required documents and can't replace them?
That depends. Do you have an employee identification card?
No, sorry.
Do you have a school identification card?
Yes, we do have one of those.
Then you'll only need a U.S. passport and that should be enough.
What if I don't have the old name of my child on any of those though?
