The official reasons often given are that financial capability has not been demonstrated, and the requirement to return to one's country at the end of one's studies. Even our post-secondary institutions do not really have information on the reasons for these rejections.
We propose that there be a better exchange of information between IRCC and the institutions that want to recruit students on the reasons for refusal. Institutions often support applicants, but sometimes they are informed about the refusals only when the students do not show up. Moreover, the reason for the refusal is unfortunately not shared.
However, that important information should be made public and shared with the institutions to better support the recruitment and support of students abroad.
