Here's the story: Mother filed petition for brother when he was 19. 2 years later (now), the I-130 is approved. Visa bulletin is current. Based on the Child Status Protection Act, he's still 19 (after deducting the 2-year wait for the i-130 - he's actually 21). Everything is now at the NVC. We paid the the initial fee (for the affidavit of support) and submitted financial documents. Now...here's the issue. At the top, for visa class, it says "F24". F24 is for "Unmarried son or daughter (21 years of age or older) of a lawful permanent resident alien."
I asked an attorney, and he suggested we send a letter explaining the situation (that the Child Status Protection Act applies to him, to please update visa class and have them send invoice for visa form).
Has anyone had any sort of experience with this? Should we send the letter or wait a bit and see if there are any updates?
