my question is who has experience or knowledge about the second attempt of a student visa, not about what is correct or wrong. What do you think the majority of students do when they graduate from their studies in Canada?
If you did not complete your studies, would you return home? There is no indication of that
If you enter Canada and not show up for classes, would you return home? There is no indication of that.
If you run out of money during your studies and cannot continue, would you return home? There is no indication of that?
If you fall very sick or get into an accident and have to drop out of school, would you return home? There is no indication of that.
Of course when you complete your studies, you are welcomed to apply for a work permit, what if you don't get one or you don't qualify for a work permit? Would you return home? There is no indication of that.
Yes of course the majority of students who completed their studies AND got their work permits can stay in Canada, but if you don't? How would the visa officer be satisfied that you will leave Canada after your temporary stay?
