CSPA Section 6, Please help!

我想应该有人跟我有一样的疑问.

My parents filed in I-130 for me when they were LPR and I falled under F2B category back to that date.

After 5-6 years when my PD is about to be current, they got their citizenship.

Theoretically, i should become to F1 once they got their citizenship.

However, F2B date moves much more faster than F1 nowadays so I wonder if I can keep my status in F2B but not F1.

I found that there is an act signed by Bush, www.uscis.gov/sites/default/files/USCIS/Laws/Memoranda/Static_Files_Memoranda/Archives%201998-2008/2004/cspa_sec6_32304.pdf, which matches my situation perfectly. 

I wonder if I should submit my request following the instruction from : www.uscis.gov/green-card/green-card-processes-and-procedures/child-status-protection-act/child-status-protection-act-cspa and submit a request for Opt-out?

Or should I wait till my PD as F1 becomes current??

Any recommendation??
