Be careful. To complete your program and graduate you need a valid study permit or a proof of application if you are renewing it (implied status). During this period you can work.
After the reception of your official letter and transcripts:
- if you have a valid study permit you have to apply for a PGWP and you can work full time.
- If you have an implied status, you have to stop any working activities and wait until your receive your new study permit. The day you receive it you can apply for a PGWP and start working full time.
Hope this is clear.
