My application for pgwp was approved the first time with a 3 yr permit. I submitted a detailed explanation letter explaining my situation with my application and it took 3 months. That said, the last three months were the most stressful months in my life. Not knowing about your future really sucks. i know that a lot of people here might be in a similar situation so my advice to them would be to write explanation letters with evidence and going into as much detail as possible to clarify your situation to the immigration officer. Good luck everyone.
