Can Canadian immigrants apply for a study visa while waiting?

Compared with applicants who are not waiting for immigration, the difficulty has increased. The reason for this is the following：

According to Canada's immigration law, if an applicant wants to obtain a study permit (student visa), he must convince the visa officer that the applicant will leave Canada after graduation (of course, there are other conditions, which are not detailed here). However, if the applicant has applied for immigration, the visa officer may not be satisfied with the above terms. Therefore, it is necessary to make more and more effective explanations according to the specific situation.

However, this is not absolutely impossible. I once helped a student in this situation, and finally, I successfully got a student visa. A year and a half later, her family immigrated successfully.
