In 2005 November I had I485 Interview and was approved for a 10 year green card, now (2015) finally have time to apply for Citizenship (n400), collected all the paperwork and accidentally noticed that I had Ticket back in 2005 for "Underage public intoxication" Basically police stopped me on the parking lot while i was walking, made me breath and issued me a ticket. No fingerprints, no arrests. This happened ONE MONTH before my I 485 Green Card Interview. I DID NOT MENTIONED this on the interview, simply because i did not know that it is crime at all, I was under impression it was falling under "Traffic" issues. Talked to the lawyer today, he is saying that it is bad but he can rule this out, I will receive my citizenship and i will not have any issues. I am just trying to understand what mechanism layer will use to explain this accident to the immigration officer. Also lawyer mentioned that this "ticket" is considered as arrest.
Thanks.
