Same here forgot to fill the same sister/brother of wife rest was OK
I would say, fill the same form again and send it using Webform or mail them with a detailed letter. You guys should be good.I have missed filling the column relationship in IMM5406 under "Section C" (i.e Brother/Sister) for both English & Native application, but i have added the details of the person expect the relationship. Do they return the file? Any idea?
