So if the sponsor is a canadian citizen he/she can travel to see his/her spouse (PA) ? Also is it an issue for the PA to travel outside the country they reside while their application is being processed. So say the sponsor who is a canadian citizen decides to fly out to PA's country and travel together to countries neither of them reside in.
I would say PA is free to go anywhere, especially if it's less than 183 days per year, so it wouldn't cause any issues with police certificates and "being reside in another country" stuff.
For a sponsor (please anyone correct me if I'm wrong) it also should be totally fine, but there is a catch.
So as stated above, a PR can't sponsor anybody living outside of Canada. A citizen
can sponsor living outside of Canada but needs to provide evidences that he/she will return to Canada after sponsorship is approved. So as above suggested, if for PR travelling for a long time can cause issues "not being present in Canada", so that for a citizen? If you're a citizen travelling for months, that means you need to provide evidences of return? And if you didn't then what?
