dob: 03/04/1983
date of entry: may of 1995
dad's naturalization: 1992 or 1994 im not sure
marital status:
me and my other siblings were born out of wedlock when my dad got his citizenship he went bck home and married my mom and my dad petitioned us and arrived in USA on 1995.
When your dad married your mom YOU WERE UNDER 16 and on that day, you became legitimate UNLESS you were legitimated before then under the laws of the place where you were born and/or resided before they married.
Your dad petitioned for you as an IR-2, child of a USC, right?
The new law "Child Citizenship Act of 2000" (CCA) became effective
on 2/27/2001. That new law only requires one USC parent by birth or naturalization for the legal
LPR child under age 18 who is living with the USC parent to become a USC.
(USC parent qualifies: child was born in wedlock/
legitimated/custody after divorce/sole surviving parent/unwed mother.)
According to what you have said, you became a USC on 2/27/2001, at the age of 17 yrs, 9 months and 23 days old while living in the U.S. with your parents , one of whom was a USC, and you had a greencard. [IF you were abroad and did not return until
after age 18, you are not a USC.] [IF mom naturalized before 2/27/2001, then you became a USC the same day as her.]
File for the Certificate of Citizenship on form N-600. READ the form instructions, most, if not all, of your evidence is in your immigration A-file already. They probably have your B/C, parents' M/C, and copy of dad's natz cert. They can check in mom and dad's files if they need to.
