IRCC's strategy is to keep the FSW scores as high as possible to force the out-land applicants to apply for a student visa first. By this method, they will bring more money to Canada because the cost of their immigration is increased by the international student fees which are usually above 15k CAD per year.
These guys do not like FSW candidates. Let's admit it. They want FSW guys to look for more expensive options for their dreams. Countries like India and China have a lot of citizens to fall in this trap, and the rest of the FSWs suffer as a consequence. Canada currently has more than 0.5 million international students which are paying at least 7.5 billion CAD as tuition fees excluding their living costs which are also supplied from their home countries.
If FSW points were as low as 350s could there be these many international students in Canada? Of course not, they would have applied through EE and paid domestic fees if their intention is to study. We all know that it is not at all, so they would have been easily become a Canadian PR without ''donating'' billions of cash to Canadian institution.
See what's going on?
