Mine got refusedThen no problem. Don’t worry.
Cause mine was also Concordia university.
1- get a status letter that shows you were a full-time student
2- get you completion letter or degree conferred letter if you got your degree
3-get your official transcript
4- any other documents that are listed by ISO or immigration
Apply, I don’t think you face a problem.
If in any case they recused you contact me via this forum, I will help you prepare an explanation letter as I did for my friend who got refused because of one LOA and then we applied for reconsideration and they accepted our letter and finally issued his PGWP.
