I don’t think Nadra will allow you to do that but you can try...Can they manually add my saasu maa brothers which are not showing up in family tree during online application? I gave a visit yesterday and came to know that those 2 brothers have to update their cnic and get themselves included in the family (Which off course is the process I don't want to get into due to their strained relation)
So, should I visit Nadra and get the FRC made then and there?
