Quebec selects immigrants to settle within the province. For Quebec immigration, candidates need to first get a CSQ (which isn‘t a PR Visa).
Once an application for a CSQ is submitted, the qualifications of the candidates are subjected to assessment at the provincial level. After getting approval for CSQ, the candidate must apply for medical and security checks at the federal level. After a candidate gets approval at the federal level, he/she gets Canada PR, completing the Quebec immigration process.
