Request for Initial Evidence of I-130 Petitioner Citizenship document

[Dash7]

Hi,

I filed I-130 & I-485 (Together & also I-131, I-765) in September in F2A Category (my wife is Green Card Holder).

Currently, I am on H1B.

Priority Date: 17 September 2019
Fingerprint Appointment: 18 October 2019 (Notice date: 27 September 2019)
Fingerprint Review is completed as of 18 October 2019.

RFE issued on 11/06/2019 (online status update). Received in mail on 11/12/2019.

RFE Stats that " This office is unable to complete processing of I-485. We need more information from you in order to make a decision. You must submit evidence to establish that the petitioner on Form I-130 is a United States Citizen."

1. Copy of birth certificate shows birth in the US.
2. Naturalization Certificate of Citizenship.

Anyone, please suggest what should be the further step?

Thanks in advance
