Hi, I received an RFE from my I-485 asking me for my marriage certificate and my I-693. I sent everything through the mail with FEDEX (original with seal marriage certificate and I-693 sealed by the doctor) and it says it was received and signed for on 12/19/2022. But my status online hasn't changed. It still says "Request for Initial Evidence was Sent". I have tried the chat on the USCIS website and they won't confirm that they received my package and keep saying I have to wait 60 days after I sent the response to talk to them again. Has anyone experienced that? I am trying to stay calm and wait the 60 days, but I'm scared and can't think about anything else.
My timeline:
USCIS received I-485 - September 22nd, 2022
Scheduled Biometrics - September 30th, 2022
Biometrics Appointment - October 17th, 2022 (Case status changed to "Being actively reviewed" on this same day)
RFE was sent - December 5th, 2022 (letter available online 2 days after that, then response was received according to FEDEX on December 19th, 2022).
Thank you.
