Had my N-400/I-751 combo interview last week and passed. Was approved for same-day oath and got my passport the next day. So glad to be officially done! Overall took 5.5 months for N-400 and 14.75 months for I-751.
Interview was scheduled for 9am. We entered at 8:45am and were called in at 9am. Finished at about 9:30am. Oath ceremony was at 11am and we were out by 12pm. The IO was very kind, courteous, professional, and it was just generally an enjoyable conversation for something so official. Everyone was really professional but the security guards could have been a little nicer with explaining the not-quite-TSA-style rules for the scanner.
The IO mentioned how organized our packet was and that everything we submitted was more than enough. She also said "I'm sure you have more documents to give me but I already have enough." Very few questions asked, mostly standard ones around being arrested, owing taxes, selective service registration, and the rest of the N-400 questions. I mentioned a parking ticket and an automated speeding ticket. She asked if I paid them, but didn't ask for any proof. I also clarified one date that was entered wrong for my travel dates and she fixed it according to CBP records she had access to, but said it being incorrect wasn't a problem really since I wasn't even close to being out of the country for 548 days.
Started with the N-400 citizenship test and then briefly asked my spouse and I questions about the I-751: "How did you meet? When did you get married? How have things been? No separation?" I also had to travel for several months in the US due to work and I brought that up and the IO asked, "So that was for work?" and I said, "Yes, I had to be on site" and she said she sees that in what we submitted and that was understandable. She asked us if we were cat or dog people based on some of the photos and liked that we indicated who was in each photo, when it was taken, and where. She commented a lot on the amount of evidence — including the photos — that we submitted, and our jobs, saying "You've convinced me you're a legitimate couple. Congratulations, I am approving both forms today." The interview was in total maybe 10-15 minutes. The remaining 10-15 minutes was us chatting while she processed our approval and scheduled the oath.
Philadelphia FO does not normally do same-day oath but I mentioned having a family medical emergency (I showed evidence of it) that I needed to travel for internationally. The IO got approval from her supervisor to approve me for same day oath. Otherwise it would have been 2-4 weeks for the oath.
Things I've done so far after citizenship:
