So I had a somehow similar situation. Just to add to some context to mine:
We moved from WV to OH in August 2021. I even filed my ROC with my new address, got official USCIS notices, etc. I also filed AR-11 for change of address. Come February 2023 I applied for N400 and they sent me to WV for my biometrics. Meanwhile, I have an ASC that's not even 20' away from my home. My original appointment was Febr 23rd. I just took a walk in on Feb 4th in my ASC, and not only did they allow me to do biometrics, but they also explained to me the following:
During the pandemic, some ASC or field offices were closed, and they routed those cases to nearby offices. Even though their offices are fully operational now, USCIS headquarters hasn't picked up on this and they still send applicants to far away places. It might be your case.
Your parents might not be able to do a walk in, though, since it's an interview. I'm just trying to provide you with a possible explanation.
I called USCIS prior to attempting a walk- in and the lady said "no, don't attempt a walk in, we will get you scheduled for one in the next 30 days". I am glad I didnt listen to her, as they never called me and I am already a USC.
So whatever you do, do not reschedule!
