Child crossed 21 - CSPA Act / calculation

[AJK_1]

Hi Friends

Here is my details,

I-130 Filed : December-2003
I-130 Approved : November-2009

Child Age (DOB: Jan 1994) at I-130 Filed : 7 years & he turned 21 years in January 2015.

Please advise : Do we just have additional 6 year (time between I-130 filed and approved) to be eligible for Visa based on CSPA? Means, if visa becomes available in 2017 then only this child will be eligible for visa with his parents based on CSPA ?

Appreciate any feedback

Thanks a lot
