Thank you!
I had the interview this morning at 8:10 AM. In case I didn't mention it earlier in the thread, my application was within the 3-year rule (spouse of US citizen). My I-751 had been approved last summer and I have been having my 10-year green card since July.
I passed the civics and English test with flying colors. The officer then asked me questions from my application and we made some updates. She was very impressed that I knew (in detail) what the Oath of allegiance is about. She then asked me to show our current lease, a 2024 bank account statement, and car insurance, which I had all with me. She then asked if I have a long-form car insurance and I said I only have what I gave her (which was the insurance card with both our names on it). Then she asked to see our son's birth certificate, which I also had. She then asked what other documents I had with me and she didn't want anything of what I listed (2020, 2021, 2022 tax transcripts - since we haven't yet filed 2023, joint car loan from 2021, older leases, older bank account and credit card statements), she did say yes to me showing her our driver license photos showing both of us having the same residence address (our residence address is different than our physical address: residence address is at my FIL's house, physical address is the one we actually live at but both are joint of course.)
At the end she said that I passed the English and civics test and that the interview all went well, but that she is having some technical difficulties in the system that it's not letting her stamp the approval. (she did do a lot of typing and clicking on her computer before saying that, so I could tell she had been trying to get it through). So she handed me the N-652 form with "A decision cannot be made yet about your application" (no written detail about why, I only have what she said verbally about the technical difficulties). She also said that I will receive my oath scheduling letter within 30 days and she gave me details about how the oath ceremony will go (no guests and about 2 hours total time, if scheduled at the same location as the field office I interviewed at, as it's a small ceremony venue, or, guests allowed and about 4-5 hours total time, if scheduled at the other ceremony location which is a school, dress formally, etc.)
Our case is strong and we have tons of evidence so I'm not worried about that (including I-751 approved in record time with no interview), I'm just disappointed being stuck in this limbo (which I know from a thread here that can last anywhere from a day to over a year). My status in myUSCIS still says "Interview was scheduled" sooo... I guess now we wait :).
