Unmarried child of Permanent Resident is now over 21, and resident is Citizen.

[Criciuma]

Hello all,
A family member that resides in a different country, was entered in a I-130 from his mother and I am trying to help him out.
His mother at the time had the 2 year green card, through marriage.
The document receipt I-797 reads: Approval notice: Section: Unmarried Child under 21 of US Resident.
He is now 25, his mother is a US citizen, so hence my confusion.
Under which category of the visa bulletin does he fall?
Priority date is June 2008 by the way.

Was the child's mother a Permanent Resident or Green Card holder when she petitioned him.

If a Permanent Resident, the child's visa class is F2B, so long as the mother informs USCIS or the NVC that she wants to retain "Permanent Resident petition status" after she became a U. S. citizen.

If mom was a citizen when she petitioned child, the child is now F1.

In what country is the child residing/citizen of?

Hi rayb, thanks for answering.
I updated my question.
The kid lives in Brazil, the mother was also born there.
