had my interview today, IO asked me for passport,DL and GC, then I was asked to sign in several places, that made me think that the IO was going to approve it as long as I did not mess up, and mess up I did not, then he asked 10 questions, it was more like rapid round, then talked through the N400, very professional and courteous, ticked passed and congrats and told me to expect oath letter for Jul. It was quick and smooth
