I don't know for the forum, but at my work place more than 100 PNPs got PR over the last 2 years, no problem. Only couple of people got rejections, and all due to failing Medicals, that's to the best of my knowledge. As for me, PNP looks like one of the safest way to secure PR. Me stupid, should have done it myself, but chose not too. Sorry about it now. Good luck with your application!
