If you are applying for closed work permit application your employer have to submit job offer in employer portal account and pay $230 fees and give you job offer number starting with A123456789 . You have to fill that job offer detail and number in work permit application and attach compliance fees receipt too . Attach work permit support letter from Province along with nomination letter from Province. If you apply closed work permit application without submitting job offer it will be rejected.Can you please tell me what is process to apply closed work permit? My letter validity is till January 2024. So looking to apply from now only.
