LMIA - you reapply if you can address the reasons for refusal. You must add information to prove that you will not remain in Canada and prove you can do the job. IRCC doesn’t believe you have complied with immigration status. It seems you may have been on a study permit but not studying so would have lost status. You have been in Canada such a long time without completing studies.What do you suggest to me?
Study permit - focus on admission and approval of study permit showing that you can complete program, have your own funds, and will return home.
