On my N400 I should have put some traffic violations under $500 but I didn't due to bad advise received from USCIS telephone help personnel ... in addition, one of the previous addresses that I have provided on N400 is incorrect ... what can I do to amend these two mistakes on my application? Would this be considered as a HUGE negative at the interview? My interview date is barely a month away from today ... please help!!! Should I contact USCIS by telephone or write to them explaining these two things or do I take an updated N400 with me to the interview and explain this to the interviewer? Please help!!!
