Like many folks on this forum(and this after reading the forum threads a few times!) I made the mistake of not declaring my speeding tickets on the N-400(coz I did not realize that traffic tickets are considered a citation). A few days after I mailed my N400 I mailed a clarification letter and an updated version of the page(not the entire N400) where I declared the tickets.
At my interview the officer asked me absolutely nothing at all about the tickets. As he was flipping thru' the app I noticed that the file did not have my updated page. At that point I was in two minds - should I or should I not mention it? As the officer finished the interview and was congratulating me I thought -- what the heck, let me mention it so that it does not come back to bite me. I did and he said it was irrelevant since they were only speeding tickets. He made no notes whatsoever. A couple of days after my interview(which was more than 4 months after my PD) I recd a letter from USCIS in response to my updated N400(where I declared the tickets) and guess what --- they said they were seriously backlogged and expected to process my letter by Oct!
My interview was on June 22 and I'm scheduled to attend the oath ceremony on Jul 22. Hopefully in Oct 2005(more than 7 months after I sent my clarification) USCIS does not change its mind on granting me citizenship
