Hello all, I completed the application forms for my parent for 600. Under the "group processing", I added my mother as well. Now I got the letter for only my father to complete the biometrics, but not my mother. On the Immi account, it only shows my father as the main applicant. There is no information about my mother whatsoever. Is it normal? Or should I create a new application for my mother now? Thank you in advance and good luck to all of us!
