RULES OF WORKING AS A STUDENT
Prior to 2006, international students with student work permit can only work 20 hours maximum off campus, after completing 6 months of full time study but since 2014. International student can now work 20 hours immediately their study begins and more hours while on break.

Rules and responsibilities: these are the ties that bind us. We do what we do, because of who we are. If we did otherwise, we would not be ourselves. I will do what I have to do. And I will do what I must.quote from https://www.goodreads.com/quotes/tag/rules
