I am a Canadian Citizen married to a Filipina who has lived in Canada now with me since I sponsored her in 2014. We are now in the process of sponsoring her adult son (my step son) to obtain his Canadian "PR" . The sponsorship application and the General application forms are ready for submission. Unfortunately, we are questioning if he actually qualifies under "Family Class" "Other Relative" ? He is my spouse's only son. Please, we are asking for clarification as to our options.
