missed notice

January 30, 2025 Notice Was Returned To USCIS Because The Post Office Could Not Deliver It. I just got this message and I am wondering what it’s about. It’s frustrating that I have changed address and I still miss my mail because they keep sending it to the old address. Has this happened to anyone before and who knows what they notice is about?(justwondering). I have done an e-request. Just my curious self trying to figure it out in a vaccum.

【ask for help】Concerns about Notice was Returned

I got a notification related to my 485 from USCIS last month, and the notification is notice was returned to USCIS because the Post Office could not deliver it. I called USCIS two times, but they don't know what the notification is. Emma said it was neither an RFE nor an interview notice. Also, Emma guessed it might be a notice that they had already gotten my fingerprint and the notice was not important. Thirty days have passed, and I am concerned about whether the notice impacts my case process. Does anyone have a similar experience?
