Update on my wife's case, so we filed for N-400 on December 2023 while I-751 pending as Cse Received (491 days). Biometrics appointment got scheduled in few days, and followed by citizenship interview for February 2024. From what I've read on other forum topics, people mentioned they got combined interview notice for pending I-751 and new N-400. In our case it was not, it only mentioned about my wife and the interview date. So I thought we kind of got a waiver of some sorts so they will skip the I-751 interview. Fast-forward to February Citizenchip interview. I was just planning to drop her off because of the covid rules, they were not allowing other than applicant to be in the waiting room. When we got there those covid restrictions were already lifted so I decided to go inside and wait. I'm glad that I did that, few minutes later USCIS officer came out and called my wife and after he has seen me nxt to her he asked me to go in first. Then officer said that reason I'm being asked for an interview is that we have I-751 pending and we'll go through combined interview I-751 and N-400.
I-751 interview was pretty quick like 2 minutes ish. He asked about how we met and how we have been living together, adding that he has no issues and said will not ask much. Same happened when my wife got called, she mentioned 2-3 questions about us and sign a paper for her answers, again taking 2-3 minutes.
N-400 interview was a breeze with English and Civics questions followed by questions about the application itself. The odd part is that officer said that she passed the Citizneship Interview and congratulated her, but he checked the box where decision cannot be made at this time. I assumed it was due to I-751 needed to be actioned before the oath ceremony.
So now we are stuck, no oath ceremony has been scheduled or any movement on I-751. Some similar posts that I found that it is taking up to 2 month to close up the I-751 and oath ceremeny to be scheduled. So I will give them another month and see what happens if not will try to get on a phone cal with the USCIS
