OCT2018 My dad got hired by his employer into the united states, so he had me and my little brother as his derivative beneficiary coming with him into the US. JUNE2019, Dad’s I-140 of my dad got approved by the uscis.DEC2020, Case was documentarily qualified but me as an derivative beneficiary of my dad.Got myself a newborn child born on NOV2021 which is my father grandchild. Due to lack of knowledge or being illitirate we dont know how to update my case for me to include my son at the application cause the ds260 was locked. But then We’ve got our interview and JAN2024 and at the time of interview consular asked me if im married i said no which is true. But i told him that ive fathered a child back on NOV2021. He said thats fine you can add your dependent when you entered the united states. MAY2024 got my 10 years LPR. Didnt have to fill up information to input my child. We just paid the $235 fee. Im wondering where would i update it???
