My wife is already a PR . She is scheduled to fly to canada in mid June with our 1 year old daughter (daughter has TRV). I am already in Canada and will be the sponsor for my child's PR sponsorship.What do you mean "stay back"?
In this scenario, can i just add a note instead of the imm5604 declaration (declaration from non accompanying parent) stating that even though my wife (child's mother) is not a co-sponsor she is already a PR and will accompany my kid in June and we will all settle down in canada as Permanent Residents.
