Hi, I obtained an offer letter for postdoc from University of Alberta said that the first day of employ is Nov. 1. 2017, right now I'm in the US and the last day of legal stay is Oct. 31. 2017, however, I just checked the CIC website and it shows that the estimate processing date for work permit is 84 days. My home country is China. I do not want to go back to my home country to apply for the working permit.But if I stay in the US to apply for the working permit, this will cause me illegal stay in the US. So I'm asking is there a way to accrelate my application? Thanks.
