It is in your best interest to not study any further until you resolve this issue and get a valid study permit because any studying you have done, if you still have a valid study permit for the initial school, would not count towards PGWP. Is the new school and degree the equivalent level of education? For example changing from a 2 year post graduate diploma at a public college to another 2 year post graduate diploma at a different public college.I didn’t register at my first school after I have arrived in July and I get admission at other school and other study permits in September do I need to update on my IRCC account about the changes? If this break the law how do I amend it?
