If your occupation is regulated in Saskatchewan, you must contact the regulatory body to learn what you will need to do to work in Saskatchewan.What is the license? Is it work permit or another thing??
Applicants to the Saskatchewan Immigrant Nominee Program (SINP) intending to work in a regulated occupation must provide proof of eligibility to be licensed as part of their SINP application.
