Aug 2016 AINP applicant here as well. Just passed MR, waiting for PPR and my first BOWP is going to expire end of Jan which is the 16/17 month mark since AOR. From what I read on the CIC website, applicants in our situation can continue to work and stay in Canada after the expiration of the BOWP under an "implied status" to wait for the PNP federal application verdict. I actually tried to apply for a second BOWP a while ago but there was no such option for a "second" BOWP, the only option to apply a second BOWP is as if you are applying to a BOWP for the first time which requires the provincial nomination letter that has likely long expired and a job offer which doesn't make sense for people who lost their job after they had established their federal application as well as contradicting to the "Open" part of the BOWP. My question to you is how did you get your second BOWP? My understanding is that it is a waste of money and you could just continue to wait and work normally until your federal PR grant/decision after the expiration of your current BOWP...
Correct me if I'm wrong, folks...
