My father is a principal applicant and my mother is his spouse, and I'm their daughter is the sponsor. My dad has a son from 1st marriage who is 48 years old, who is married and lives in the different country not in Canada and not in the country where my parants are immigrating, does my half brother needs to identify himself in any way and fill out IMM 5476? If yes what documents my half brother needs to provide to support his identity? Do I need to fill out IMM5406 as well as I'm a sponsor and show my half brother in the form as well. If we all start filling out the same form there is a lot of duplication? So it is quite confusing who needs to fill out IMM 5406 just my mom and my dad, or myself and my half brother as well, please confirm
thanks
thanks
