I am about to apply for US Citizenship, and meet all the requirements. However, I was arrested for underage consumption of alcohol when I was 18. In court my lawyer got me into pretrial diversion and having successfully completed the program, my record was expunged. I know the application for citizenship says you must list all offenses, even ones that were expunged, but I do not wish for this to hurt my chances for getting my citizenship. How seriously does this offence affect my chances of getting my citizenship? If it seriously effects it, should I risk not listing it on my application, or should I just come clean regardless? I have no other criminal offenses or otherwise, have been a permanent resident for ten years.
