A JAL doesn’t allow you to apply for a permit. So has your employer paid for the Employer Compliance fee with IRCC? If so you will get a LMIA exempt number. Ask employer for LMIA exemption number.
If the nominee is not currently working in Saskatchewan, they will use the SINP Work Permit Support Letter to apply for a temporary work permit, through the
International Mobility Program, to allow them to work in Saskatchewan while they apply for permanent residency. To enable the worker you hired to start working in Saskatchewan as soon as possible, you must support their application for a temporary work permit. The nominee must apply for a work permit immediately after nomination by the SINP.
To obtain a work permit for the nominee you have hired, Immigration, Refugees and Citizenship Canada (IRCC) requires employers to complete an online form and pay an Employer Compliance Fee of $230 for each foreign national requiring an Employer-specific Work Permit. Employers submit the offer of employment form and pay the employer compliance fee through the
IRCC Employer Portal. Please see the IRCC Employer Portal
User Guide for information about the process. In the Employer Portal, when you "Create an offer of employment," you will use the LMIA exemption title "T13" when you are hiring a SINP nominee. You will need to provide your candidate with the offer of employment number (A#######) generated by the system once you submit your application through the IRCC Employer Portal.
