You don't HAVE Canadian citizenship so you cannot "cancel" it and you will not get a proof of cancellation.stellahello said:the job I am offered requires me to have Korean citizenship and proof of cancellation of Canadian citizenship if I became Canadian voluntarily. So my question was that if I cancel Canadian citizenship, am I not holding permanent status either? will I be treated as visitor/study permit holder/foreign worker? right?
Right now you only have a PR status. If you don't go to the oath, nothing will change.
You will still have your PR status for a while, even if you leave Canada.
But you will lose it if you live outside of Canada for too long.
How "long" is "too long" depends on your past travels, but it won't be more than 3 years - doesn't matter what the expiry date on your PR card is.
Once that happens, you will be just a regular visitor, who will require a study permit to study and a work permit to work here.
On the other hand it looks like South Korea is one of the visa-exempt countries, so you will not need a visa to enter Canada
as a visitor after you lose your PR status.
