My wife and I have a child who was born before we married and before they came to the US.Now they are here and have a greencard (both).I am USC. How can I get the child citizenship? It seems the N-600 requires the child be a natural child.
I was thinking of getting a DNA test done and send those tests along with the birth certificate,proving am the dad.How acceptable is that, to show am the natural father?
Further clarification:
Child was born outside US.Parent became USC AFTER child was born hence child could not become USC at birth.
Any ideas?
Looks to me you will have to legally adopt your child.
Have legal and physical custody of child for 2 years and your child will automatically become a USC 2 years from date of final adoption decree
N-600 doesn't require the child to be natural. Can be adopted also!
Applying for US passport doesn't require natural child either.
Only 2 ways to find out if child does have USC is the N-600 or applying for passport.
Passport is cheaper. $92
I'm still waiting to hear a final decision from them. There's seem to be a few of variables.
