Talk to the international office at your uni for immigration advice. They must have already seen this kind of thing happening with graduates of your uni. My two cents. Don't decline unless you have spoken to them and they advised you to do so.
They have been instructed not to share info. About express entry to international students!... It looks like they take 500$ outside of the university for EE consultancy... I just graduated.. i dont wanna waste money on that... ppl who knew by consulting a lawyer dont share too!!
