You need to establish your citizenship with Social Security if you haven't already.
Have you done so?
It should be in your records already.
I don't have any official U.S. documents, they were lost in a fire recently.
If that is the case, other documents may be deemed acceptable such as an officlal employee card.
I have such a card but it has expired, is that okay?
All documents submitted to us must be current and not expired so you must procure a new one.
Oh I have my passport can I use it for proof of who I am?
One document may be used both to prove your citizenship and identity.
I was issued a card by my state, is that acceptable?
