You don’t need another work authorization letter. You can call them and they’d let you know this. You are on maintained status and as such, are legally authorized to work full-time. It’s also on their website. So long as you applied before the expiry of your study permit.Congratulations and good to hear as I am waiting from June 9th. I am just wondering if you asked for or received a work authorization extension letter after 4 months of applying?
