It's not material misrep, so you should be fine for your own citizenship. However, because of the situation, they may ask for DNA testing before issuing a visa/ giving your son the CRBA (are you named on the birth cert?).

Thanks for the answer!

Yes, mi fiancee says, I am named on the birth certificate

Thank you all guys for your help!

I admit few people have ever been in my situation.

If you weren't a US citizen when the child was born then the CRBA isn't an issue. The child isn't eligible for US citizen by birth. The child will, however, become a US citizen when it's admitted to the US as an immigrant in your custody.

It isn't misrepresentation unless you knew the truth and willfully concealed it.

What sort of visa are planning to petition for?

Thank you a lot for the replies!

If I can be sure that it won't affect my citizenship, then I would prefer an emmigrant visa, which will let them recieve a green-card within a month after they enter the US.

Thank for the reply beforehand!

I am really confused and worried and angry and happy!!! I just learned that about three years ago my fiancee gave birth to my second child and concealed it from me till I informed her of my decision to marry her and have her and my 6 year old daughter beside me in USA.Well she had her reasons and I try not to blame her and now one thing worries me greatly.

I am a US citizen now and while applying for citizenship, there was a question in the form concerning the children and I informed of only my 6 year-old daughter as I didn't know that I have a second child at that time. And I relly want to have them beside me.

Do you think it's a problem that I didn't tell the immigratiojn services of my second child and what can I do in this situation to bring them to US as soon as possiable?
