N-400 or N-600

[tennnis123 14]

Hi guys, I am trying to help a friend to become a citizen and we are confused on which form he has to use. His mom and him became residents because she got married to an American citizen (his stepdad), he procrastinated 11 years before he decided to become a citizen, he even renewed his 10 years GC . Now he is 23yo and he was 5yo in Feb of 2001. His mom and stepdad are still together and she became a citizen long time ago but he didn't. 

If someone can please help us with this, we think he needs to fill the N-600 but we would like to be sure. Also is there a preference between online and mail for the N-400? 

Any help is very appreciated

How old was he when the mother took the oath?

He was 17yo when she became a citizen. They sent the application for N-600 but then they moved apartments and didn't follow up with the process

hi

 

if he was a resident when she became a USC, and under 18, then he derived citizenship if he can prove that he lived with her

 

the certificate isn't mandatory, it's optional, he can get a US passport without the N600

 

it's his choice

They paid the fee and everything?

Yup - they actually filed twice and for some reason the process fell through the cracks both times.

Based on what you mentioned he automatic became a U.S. citizen the moment his mom naturalized since he was under 18 years of age, a lawful permanent resident, and also under her custody. The fastest and cheapest way will be applying for a U.S. passport directly. He can always apply for N 600 later when he has more than $1000 to burn for it.
