From the looks of it, international students expecting to get their PR should expect to do 5+ years of post-secondary schooling in Canada and then get 1+ years of Canadian working experience at a 0, A or B level. The student should also score at least 10/12 in all 4 categories in the CELPIP. That should get you PR in Canada. Example below.
- 4 Year Bachelors degree at Canadian University
- 1 Year post Grad certificate program at Canadian College
- Minimum 10/12 in all 4 categories in CELPIP
- 1 Year Canadian work experience at 0, A, or B level
You will have to apply for a 3 year PGWP after the 1-year grad program or 4-year bachelor degree. This will give you 3 years to get at least 1 year of Canadian work experience. 2 years is better though to increase your score
That will get you a CRS score of 462. Once you get 2 years of experience, your score will go up to 477. This should give you almost 100% change of getting PR with the current system. However, Canada could easily change their immigration programs which would alter everything.
