If you qualify for the skilled worker program with 67 points but you need a category to apply under (not in the list of 38 and no job offer), if you go to Canada for a year on a student visa or work visa, you would be able to apply under category 3 after 1 year.
There are three categories under Federal Skilled worker Program
1- FSW1 - For people who have experience in the 38 ministerial list of designations.
2. FSW2 - For People who have AEO-Arranged employment offer from Canadian Employer in Canada.
3. FSW3- For international students spent at least 1 year in Canada or Workers on work permit who have spent 1 year or more in Canada.
