GC through Marriage

[darkside4391]

I currently have a approved i130 from my father and waiting for my interview date. since my interview will be held in the philippines, my father has to apply for citizenship in order for me to have my interview in los angeles. i came in the states when i was 1 on a tourist visa and overstayed. is there anyway that my approved i130 from my father still be approved if i decide to get married to my gf of 2 years? if not what would be faster, have my dad apply for citizenship then have my approved i130 transfer over so i can automaticaly apply for my i485 or marry my gf? thanks. btw im turning 21 in april 2012. my gf is willing to marry me if i can get a work permit or a a number asap.

Since you are under 21 years of age, you are considered a IR of a USC and your overstay will be overlooked. It will take just about the same time, well actually with your GF if you marry her it will probably take more time and scrutiny as marriages are more likely to be investigated.
Stick with your fathers petition.
