Hi everyone :-) I have a question concerning CSPA.

My father applied on behalf of me for immigration visa in 2000 (he was LPR and still is), but my petition wasn't approved yet.
In year 2000 I was 19 years old and I reached age of 21 in November 2002. As well as I know I fulfill all the requirements of CSPA and I understand that I should be considered as a "child of premanent resident".
I don't know in which category I am right now, in F2b as unmerried dauther of LPR (since I am no longer 21) or in F2a as a child of LPR (taking CSPA under consideration). But I guess that I am in F2b, unfortunately, which means that I will have to wait longer.

And my question is - do I have to notify NVC or USCIS that I am eligible for CSPA or they verify that themselves? If I do have to, what should I send to them - cover letter with the copy of my I-130 or something else? and can I do that before my application is approved?

I hope that someone will be able to help me, thanx in advance .

Hi everybody. I see that there are some insights into my post but there is no response :-(. Is anybody there who can help me?? I will be grateful for any response. Thank you.
