N600 or N400
 

Hello All,

I have a question for me and my wife status to naturalize and not sure for which form to use in our case.

First of on my case, I was 12 yrs old living in the Philippines when my father on Aug. 1999 became a U.S. Citizen.
I was petitioned and lawful resident May of 2002, under the age of 18yrs old. I am now 30 yrs old and married and would
like to file for naturalization. Will that be a N600 or N400?

My wife case is, She came to U.S. as lawful resident while her dad have an on going case for his naturalization.
Her father became a U.S. Citizen when she was 11yrs old and already residing in the U.S. She is now 30yrs old and would like
to file for naturalization. Will that be N600 or N400?

You automatically became a US citizen when you entered the US. You can apply for a US passport at any time. You could also file N-600 to apply for a Certificate of Citizenship, but that doesn't really serve any purposes that a US passport doesn't, and it is much more expensive ($1170) and slower to get.
