As long as she has valid status (in her case a valid work permit), she can apply for an open work permit since you have received the AOR.just to clarify she is currently on post graduate open work permit . So I can apply for another open work permit for her right , because I have received the AOR
(it doesn't matter if her has a closed work permit or study permit or visitor status, PA can apply for OWP once the sponsorship application has received AOR)
