Hello, thanks for your video! I have a question, we are a family, mother and two brothers and we are over 18+, we live together and I will fill out the tourist visa applications for the three of us (including mine), but they will tell me their information to fill out in their application and I will upload their supports, I will only fill out the applications just because I have a better command of everything that has to do with computers and the internet, in this case it is necessary to fill out the IMM5476 Use of representative? Would it be mandatory?
