I am looking to petition my fiancee and I am a US Citizen NOT born in the USA NOR naturalized as an adult. I became a citizen UNDER the age of 18 and was given a US passport at the same time my parent was Naturalized. This is the only proof I have as a citizen. I do have an alien reg # but I do not believe I was issued a Naturalization Certificate.
My questions are:
- having ONLY a US passport, will this suffice as proof of my citizenship for the I-129F?
- if I were given a Naturalization Certificate where could I get a copy should USCIS require it? (As far as I know I never got one under my name)
- should I list my alien number on the i-129 (as it asks for an "A #" on the 1st page in Part 1 in Question No. 1) even though I don't have physical proof of a nat. cert.?
