Will my wife be allowed to leave after getting PR or is there a required time she stay here?
The reason I ask is it is her mom's birthday in Korea around the expected approval date.
There is no such thing as an "expected approval date" when it comes to CIC. It could be months before or after the date you're thinking of.
If she does get her application approved around the time she wanted to go back to Korea, then she could go back to Korea and not "land" as PR with her COPR documents until she returns to Canada.
Or as keesio mentioned, if she landed already and is waiting for PR card in the mail, she could travel as a visa-exempt passport holder. Sometimes i've heard that Korean airlines in Korea can be picky, as they may ask to see a return ticket back to Korea before they let you board the plane. I think this is rare though, so she should be ok.
If the PR card arrived in the mail in Canada while she was in Korea, then the card could also just be couriered to her in Korea.
