Canadian citizens can sponsor people while being abroad. PR's cannot. IP-8 and IRPA state that a PR must remain in Canada while the application is in progress. Also, search this forum -- others have had PR applications for their spouses/CL partners refused because they left Canada while it was in progress.what goona make a difference if sponsor is PR or citizen? My spouse is PR and his application for citizenship is under process. when i called to CIC call center they said that chances are there that they can reject port of entry, now this is confusing us as we are going for 3 weeks and our tickets and vacations are already booked, bz of that reason only we applied for multiple entries too.
As I said above, there is always a chance they could refuse at a port of entry -- it's up to CBSA. Bring the latest CIC communication with respect to your application. If they know there is a PR in process, they can also confirm it in GCMS (their computers).
WRT "multiple entries" -- CIC tries to issue them by default. You do not need to request them. They won't issue anything else, unless there is some reason to.
