Honestly, being PR or even being a citizen is like we have additional rights over work permits or student visas,s and being a citizen is like an extra additional feature which is the right to vote in Study in Canada From Pakistan.
PR gives us rights to live in Canada and after 1081 days or so roughly 3 years or so one can apply for Canadian citizenship.
Sometimes firms like Govt jobs might ask you if we are a citizen or at Atleast a PR apart from that regular private mostly don’t ask about our current status unless they have to according to their own job requirements.
