hi,
My situation is almost same. This information might help u.My date of birth is Sep 1983.
My uncle petitioned my parents along with me on 1993(F-4). We got a priority date of May 1993. We waited for 10.11 yrs{nov2003} for DS-230 form. My name was there and we filled those forms and sent those to NVC. But after waiting another 1 year(Feb 2005) the interview letter came frm the local embassy and my name was not there(cause i was +21).
Now my parents is in USA, they got their Legal permanent resident card.
Now my mom applied for me through a I-130 form on June 2,2006 along with my DS-230 paper and they sent her a receipt on June 8,2006.
Please read this topic below:
In all cases, where applicable, aged-out children would convert to the F-2B category for unmarried sons and daughters of permanent residents with a retention of the parent's priority date. This would mean that in many cases involving extended waiting times for parents, the aged out children should be able to save years in immigrating to this country. For example, in the case of parents immigrating in 2018 on the basis of a fourth preference sibling petition with a 2002 priority date where the child was 15 years of age at the time for that petition was filed, the aged out child should be able to use the 2002 priority date for an automatically converted petition to the F-2B category in 2018. As the priority date under the F-2B category would most likely be current for visa issuance, the speed of immigration would depend upon the mechanism used by BCIS/DOS to effect the automatic conversion. In a regular conversion case today where a parent previously petitioned for his or her spouse and the child was a derivative beneficiary who aged out in the process, the law requires the petitioner to file a new I-130 petition to retain the old priority date16. In this case, a mechanism would have to be devised without the necessity of a further petition because of the automatic conversion provision.
I think u didn't fill up the DS-230 form yet.......and im gussesing they will send this form for ur parents and little sister only......except u. But i think that wouldnt b a problem. Cause after your parents get a GC they will file I-130 for u in F2B category. And as the ACT Aug 2002 you will get the your parent's priority date.......which means tht the visa will b available within 1 year. When i filled up the DS-230......same thing was written in tht form. My mom talked to the Vermont service centre and they informed her about this new legislation. Im sending a file about this....this will surely help u. And in your case it will be 7.5 years from now.(5.5 yrs 4 ur parents and 2 yrs for you).
Best of luck
