I am a permanent resident of Canada, but my PR card expired in June 2023. My wife and son are with me on visitor visas. My wife’s visitor status has been extended until June 2025, while my son’s status is valid until June 2024. Unfortunately, I couldn’t extend my son’s status further because my PR card is expired. Next month, I will become eligible to apply for PR renewal, and I plan to apply for sponsorship for my family. After submitting the sponsorship application, I intend to apply for an open work permit for my wife. However, I am unsure about how to maintain my son's status. What steps should I take?
