Hi there, please advise. I am so confused. I am a PR and preparing to sponsor my spouse and two kids via 'Spouse in Canada class' category. Do i have fill 3 applications separately or 1 application is fine? If its one application my checklist is IMM 5533 and if separate then for my spouse I need to use IMM5533 and for kids 5534. But I am applying for them together. They are all living with me now in Canada and are current on visitor status. Please advise quickly if possible. thanks alot.
