I interviewed yesterday, September 20. My appointment was at 12:05 PM, I arrived about half an hour early. I was called at about 12:40. The officer was very polite and professional. She walked me through the N-400 asking me to confirm different pieces of information. The only problem occurred when the officer saw the date on my green card, which says I became a Permanent Resident in 2000. Well, turns out the INS made a mistake. I have been a PR since January 1999 but when you get a green card as a spouse of US citizen the INS gives you a conditional green card, which after two years is replaced by a permanent one after you prove you are still married to the same person. The INS put on my card the removal of conditions date, and not the Jan 99 date as it should have. The officer asked for proof that the conditions had been removed and I just had a photocopy of my old green card, and obviously I had my new card, but no proof beyond that. She was understanding, though, and she said she believed me and would have to do some work fixing my records in the computer. But she said that would not impact my application in any way. Then I took the test which came right out of the 100 standard questions. She congratulated me on passing and gave me a note with a seal saying I had passed. I was pleased when she told me that the oath would take place the same day! I waited for about another hour outside until they called me with info on the oath, then went downstairs to the oath room, waited again, and finally the ceremony. About 95 people who had just been interviewed took the oath with me. The naturalization supervisor who spoke to us said this was the 3rd ceremony of the day (!!!). She said it had been a long day but she thought we would probably prefer to have everything done the same day rather than waiting for a few more months to do the oath. I was in full agreement with her. In terms of timeline, my priority date was February 14, 2002, got fingerprinted a couple of months later, got appointment letter two and a half months ago, and I am finished now. Thanks to all of you who post to this board, I felt more prepared going to the interview . Good luck to you all.
