can I get a visa and open work permit after getting my CSQ?

[9102574]

Hi guys,
I have a situation which is a little complicated and hope someone can answer my question.

I am currently in Canada, but my visa has already gotten expired and my post-graduation work permit is going to be expired in one month. I hope I can pass the french oral exam by the end of the month and then apply for CSQ till I am in Canada. Because my work permit is gonna be expired, so I should go back to my home country while I am waiting for my csq to be approved. So my question is that when I get my CSQ, can I apply for a Canadian visa and an open or close work permit and then come back to Canada?

Thanks in advance
