A lot of other people would also like to stay in Canada forever but they also must apply for their PR, fulfil requirements and wait their turn.
For somebody who comes with the plan to immigrate, if they can not get a job and come on a work visa, the best way is to do a two year course, get a post-grad work permit, work for a year and then apply under CEC which takes around 11 months. They could have their PR in less than 4 years after arriving and if they choose to study some more after that, they are paying the lower fees.
In any case, you have your application in and now you must wait. The processing time for PNP in Buffalo is listed at 13 months for 80% of cases, see
