Thanks everyone, I will try the websites suggested.
For the curious: Actually, it's not my N400 I need, but my Dad's. You see, when I filled the application for my for Dad, I cant' remember if I had included my brother's name on his application. I think I did, just not sure about it. At the time by brother was under 18, he was still under 18 when my Dad was naturalized.
Now, the problem, my brother was arrested and may face deportation if we can't prove that he was included in my Dad's application and was under 18. My dad was naturalized in 7/2000, my brother turned 18 10/2000. Someone told me if I get a copy of the N400 that shows his name was included, he may have something to stand on.
Thoughts, comments, suggestions are welcome.
You and your siblings should be included in your father's application, currently Part 9. of the N-400 ("Information about your children"). There is no reason why he'd (or you'd) not include that information.
Hence, if your brother was under 18 at that time and held a Permanent residency, he was automatically eligible.
I believe you need to fill out a N-600 form to obtain evidence of the child’s citizenship by applying for a Certificate of Citizenship(see link above).
However, I'd strongly suggest you consult an immigration attorney.
