can be birth certificate or i864w form.

@Tom Bom i864 not required for vawa. birth certificate was sent with medicals as per intial RFE.

2nd I-485 RFEs after medical are usually Form I-864W from the field office. When the notice arrives, you will know exactly what they need from you.

In some specific cases, USCIS may request the I-864w even after the VAWA approval. This typically happens if there is confusion regarding the type of status adjustment or if the immigration officer fails to properly identify the exemption that applies to VAWA beneficiaries.

it is for I-864W.

I received two, one asking for an original birth certificate, and another asking for my medical exams since the first medical exams had expired.

@Cooper P , may I know what field office your 485 located. thanks

RFE is for i864

Yes.. first one was medical.. second was birth certificate.. simple no worries
