CSPA Naturalization Problem

[hasretk51 1]

So here is my question,

My father is a LPR and he filed the I-130 form when I was 20 years old which means I am under the F2A category but now I am 23 years old as of yesterday but my petition is not approved yet while my PD (03/03/2017) is current as of today. He's been a LPR for 5 years now and he wants to apply for naturalization. If he does , does it change my F2A category to F1 because I am not under 21 years old ? In the USCIS website there are 2 points that adress this issue :

1- Child of LPR (F2A) Becomes Child of a U.S. Citizen (Immediate Relative)
2-Unmarried Son or Daughter of LPR (F2B) Becomes Unmarried Son or Daughter of U.S. Citizen (F1)

But there is no mention of a situation where a LPR files the petition for his child who is under 21 years old when the form is filed and then that LPR wants to become a citizen while his child is now 23 years old and his petition is not approved and yet his PD is current. Can we opt out of the conversion of category like "F2B to F1 ones" do.

According to the CSPA calculator, no matter when my petition would be approved, my CSPA age will be under 21 years old because my PD is already current as of today. So logically, I should be considered either under 21 when my father becomes a citizen or my category(F2A) shouldn't change since the wait time for it is less.

Your petition is still with USCIS?

Yes it is. Like I said "the petition is not approved".
