No to all. I have no skeletons in my closet. The officer said that part of my file is missing, and she needs to review it before making a final decision. I think you mixed up N400 with the A file. N400 is digital and not missing. My attorney, who accompanied me, mentioned that this can happen with old paper files. The officer also said she would approve me on the spot if it weren’t for that missing part of the file. I also did some research—unfortunately, this often occurs when older files are misplaced. I'm not sure if it's missing, because she said it has not arrived in time for the interview. Maybe it came in a week or two, just like she said, but she never got back to my file to finish it. Or maybe my file is lost, who knows?
