You are waiting for ppr, i would say wait till the ppr comes and then send you passport and they will take 2-3 weeks to return your passport, it won't take more then two months. After that you can marry and then she can apply for PR.
Finally, its all done. I am a permanent resident of Canada. Yay.... All that wait is over now. So happy. I would like to thanks everyone for their help and support.
