[jrengifo]

hi guys had a few questions first ill give u some background i was born in colombia and became a us citizen on 12/6/12
my girlfriend a colombian citizen had our son in 9/6/12
my question is my baby a us citizen or not?
also how can i bring my girlfriend and her son (im not the father) here to the US? and if so would her son also be a us citizen automaticly, because i imagine she would imigrate with a green card
thank you very much for your help

Can you clarify your question? So you are the father of one of her sons, and there is one more son of whom you are not the father? Are there two kids involved?

From your post I see that you were not a US citizen yet when your son was born. Hence, he is not a US citizen.
