Ok wasn't sure. I do know from reading the forums that they are going to have to show their intentions of returning to Canada in their application .Only PR have residency obligation to reside in Canada 2 years in a 5 year period to maintain their PR Status.......Canadian Citizens do not have any residency obligation........Also, PR in Canada could reside outside Canada and still able to maintain their PR Status under certain conditions like working outside for the Canadian Government, Military, etc...
