I just went to the BATF website:
I misread what the other document was:
The BATFE site says:
In addition to the below documents, applications must be accompanied by a signed Certification of Compliance (ATF F 5330.20) for each
additional Responsible Person (RP) on the license, if applicable.
The other document was not a citizenship document it was some kinda certification if there were multiple names on the C&R application.
My Bad...I include the other document even though the C&R application was for me only...oh, well, I hope it does not confuse them too much...
