what is the RFE about? which field office?

It is normal for the Form I-485 and Form I-485J to update on different timelines, even when filed together. The I-485J is specifically used to confirm a bona fide job offer and ability of the employer to pay, and USCIS often issues separate acknowledgment or status updates for it after RFE responses are received and logged into the system. A “RFE response received” update typically means USCIS has completed intake review and re-queued the case for officer adjudication. In terms of next steps, USCIS must review all submitted RFE evidence before issuing a final decision, and it is common for there to be a delay between RFE receipt confirmation and substantive case movement. Final adjudication or interview scheduling (if needed) typically follows once all eligibility and background checks are complete.
