Can i file for my kids, answered none to kids on citizenship forms, but i have 3

Your filing for your children after you filed and obtain your US citizenship through claiming that you had no children could certainly pose a danger if you obtained your residence status on the basis of marriage.  If that was the case, the fact that you had children with another woman during the time that you were supposed to be engaging in a bona fide marriage with the wife who sponsored you would raise grave doubts about the validity of that relationship. If U.S.C.I.S. connects the dots in that event, your permanent residence could be in jeopardy.Due to the limitations of the Lawyers.com Forums, Alan Lee, Esq.'s (the "Firm") participation in responding to questions posted herein does not constitute legal advice, nor legal representation of the person or entity posting a question.

Why did you think having children (or naming them on the form) would affect your citizenship application?
