Hello, I am a US citizen and filed I-130 for my mom. I included my 17 y.o. brother as a derivative applicant. The form was approved. After, they filled out 2 separate I-485s, which were mailed together. My mom's was approved, my brother's was denied likely because they included I-797 approval notice for I-130 only for my mom's application.
Should my brother resubmit the exact I-485 application, crossing the old dates over and including my mom's I-797 (even though it is only addressed to her)?
