I'm not sure if it will be accepted. My WP expired on monday, so I couldn't wait anymore. The waiting time for online processing is 50+ days, so I hope to have some status updates that allow the BOWP to continue.
At least now I can continue working, and I'll see what happens. My employer also submitted a WP extension application in parallel with an LMIA application. That's on paper, so almost 90 days of processing. So in case the BOWP is not approved, I still have the other option.
And with some dreaming, maybe my PR application is finished before the processing of these WP applications...
