Our family migrated to USA in 2001 on the basis of application filed by my Aunt in 80s. I could not enter the USA before turning 21 because of medical reasons and education. My younger sister and mother are US citizens now. My father and younger brother will become a citizen next year

I have been in USA since 2002, on a student visa and then on an H1B visa. I am single and my father filed an I-140 for me in Dec 2003.

My questions are
- Is there any way I can use my previous immigration approval to get a green card ?
- What is the best way of using I-140 approved in 2002 to get a Green Card ASAP ? Will my application will get bumped to Family based 1 when my father becomes citizen. Can we then apply for AOS once the priority date for Family Based 1 category crosses Dec 2003.
