Hi guys,
FYI
I applied online for extension (due to early passport expiry) of my PGWP on July 10. I requested for its withdrawal (reason was that I am afraid it will be refused because I applied online instead of paper) on August 13. I submitted application for a new work permit (closed work permit) using my SINP nomination on August 19. But then today (October 30), I got my online PGWP extension application approved. Validity completed a 3-year work permit granted to me overall.
First, they can approve ONLINE pgwp extension application. But yes maybe, it depends on whoever handles your case.
Second, they may not honor a request for withdrawal of an application. It was with a heavy heart that I requested for its withdrawal anyway.
I cannot complain with the result. I am gladdened by it.
