Hey ! Fair points & I agree with some of your statements. Honestly, lets accept most who go to study as mature adults are doing it for PR purpose which even the VO are well aware. I also agree that I would not want to return to my third world country of citizenship where I am already living a comfortable life in middle east.
My challenge however is with the fact that the profile of the person in concern should be looked at. Think about it, A person with great education & career progression will not choose to stay in Canada on a illegal status. I mean I don't see any incentive as my life will be more terrible than me actually going back home. If I see candidates with profile like these, I would say they have all the capability to legally stay back & apply for PR. Anyways, I agree my bickering will not change anything. Just letting some steam off. Peace
