I had an EE application which I withdrew before applying for the Study Permit. I want to give it another try and reapply without my spouse. And also I will try to write a strong SOP.Have you ever shown an intention to reside permanently in Canada? Or changed the purpose of visit from your previous applications, if any? It looks like the officer is convinced that you are not leaving Canada after your studies and states all possible reasons to support his/her opinion.
