I've the same situation, my work permit was expired already and applied for extend. I've not got any respond from CIC regarding my work permit though I've submitted already my passport along with family to get stamp and COPR. They received my passport on 30th July, hopefully I'll get back by the end of this week. But don't know what should I do? After getting COPR. I was planning to go back my country to bring my famy here. But get a bit nervous,I might be in problem by immigration if I entered canada with expired work permit. If somebody had same situation please share and suggest me , will be really appreciate.
