Provincial Nominee Program (PNP) can be put to use if you think your CRS is not up to the mark. PNP are immigration schemes of the provincial/territorial governments by which they pick applicants who they think are suitable to fulfill the demand in their province.
Some provinces require a full-time job offer from a Canadian Employer and some don’t. Some provinces process the applications electronically and some provinces still use the old-school snail mail method. Some provinces prefer applicants whose job falls under a particular NOC.
If you get a provincial nomination, it will add 600 points to your CRS which means, in most cases, you will get an ITA in the very next draw.
