回复：What's"All documents establishing your eligibility for Lawful

FB 485 interview is coming soon. Although most documents have been submitted with application of 130/485, the interview notice still contains a check list, and on which there are a few items I don't know:

1.All documents establishing your eligibility for Lawful PR status. Beside forms and supporting materials, what would be the typical documents for this?

-Bring all the original documents (not photocopies) you sent to USCIS for the GC application.

2. Evidence of sponsor's US citizenship?

 Would a US birth certificate work?

-Fine if the birth certificate was issued by the state government (not hospital where he/she was born).

The sponsor does not have a possport yet.

Thank you very much for any help.
