Am a Canadian Permanent Resident abroad, have applied for PRTD in order to return back to Canada because my PR card expired, my question is, what happen's with the country that have applied from, do I need a visa of that country before I exit at the airport?, Will they stamp on my PRTD at the point of exit??, Does it act as a visa until I leave the country abroad until back to Canada, I want to understand because I have no any other Document or passport of any country.
