Hi all, I am a US Citizen and filed I-130 for my mom on October 22, 2021. My mom's case got approved on the 24th of February 2023 (roughly a week ago) and it arrived at NVC yesterday. I have two brothers who were under the age of 21 and unmarried when I filed my mom's application and still are unmarried though one is now over the age of 21. At the time of filing, one of my brothers was barely under 21 born on 11/22/2000 (20 years and 11 months old) and the second is still under 21 (born on 11/29/2004). When I filed the 1-130 petition for my mom, I added their names to the I-130 application. I used an online CSPA calculator, and both qualify from the under the age of 21 perspective, but my question is do they qualify as Derivative beneficiaries of my mom's visa application?
If yes, the CEAC says I can add derivatives under the "applicant Information" section. Does that section open after pay the fees for the primary applicant because I don't see it yet? Finally, When I add the derivative/accompanying relatives (my brothers) will CEAC tell me if they qualify or not?
thank you
