I'm US citizen. I gained my citizenship thru marriage. My 2nd wife came on a tourist visa. We received notice which states that we failed to proove bona fide marriage. Main reason is that the evidence we submitted (lease, bank statements, insurance etc.) were only about one month old. This is because my wife received her ss card only 1 month before the interview and we couldn't do much before that. Also, in the notice they mention that, at the time of my naturalization oath ceremony I was legally separated (I filed for divorce a week before the oath) and misstated this fact. However it's not the reason for denial. Can they revoke my citizenship if we respond? What should we do?
