N-400 or N-600?

[Aristea Beltrame 0]

Hello everyone. I would like to explain to you an unusual case of mine. 

I was born abroad in July 1997. In January 2015, my stepmother, who is an American citizen since 2005, has applied for my permanent resident (when I was 17 years old) and my father was not a U.S. citizen yet. My father becomes a U.S. citizen 30 days before I turn 18 years old, and my green card was approved in October 2015. If I want to apply for U.S. citizenship should I file Form N-400 or Form N-600 and why?

I would appreciate some help to understand carefully this problem!
Thank you so much!
Best, 
A.

N400 is the ONLY application for citizenship.

N400, you were older than 18 when admitting as a GC holder.

Appears your father should have done CRBA in June when he naturalized, to transfer the citizenship instead of continuing with the Immigrant visa. Assuming he qualified by being present in the US for at least 5 years. 

 

But I'm not 100 percent sure. Someone else week throw all the legalise in links soon. 

Since the father was not a citizen before OP was born, a CRBA is not possible

CRBA is not 100% irrelevant here.

True! I forgot that part. Deleted my comment to avoid confusion.
