About this work
What does the officer have to be satisfied of?
Section 216 of the Regulations says an officer shall issue a study permit where the applicant applied properly, will leave Canada by the end of the period authorised for their stay, meets the requirements of that Part, has met any medical examination requirement, and has been accepted by a designated learning institution with confirmation from the school. Study in Quebec also needs a Quebec Acceptance Certificate.
The paragraph that carries most refusals is the same one that carries them on visitor visas: the applicant will leave at the end of the authorised stay. On a study permit that question gets asked through the study plan. A programme that repeats a credential the applicant already holds, or that has no connection to their work history, or that costs several times the family's annual income, invites the officer to conclude the study is not the real purpose of the trip.
Wanting to stay afterwards is not itself a problem. Section 22(2) of the Act says an intention to become a permanent resident does not preclude temporary residence where the officer is satisfied the applicant will leave at the end of the authorised stay. A study plan that explains why this programme, in this country, at this cost, is answering the question the officer is actually asking.
