No doubt, PNP is getting tough day by day in all the provinces wherever it is open for international graduates. But, Canada immigration policies are aimed at welcoming international students and offering them PR depending upon the demographic requirements. One or more provinces will continue to remain open and will welcome international graduates in their PNP programs for the next few years. So , do not worry- it will only effect the time period to get PR but eventually all students who will gain the credentials and skills both to get employable in Canada will find jobs and PR.
