I need to renew my work permit. When should I apply for the Work Permit extension?

You should file your work permit renewal at least 3 months before it expires. It’s best to apply as early as reasonably possible before expiration. If you apply too late, you may have to wait again until the new work permit is issued once your current authorization expires — meaning you could end up having to stop working. In short, apply about 3–4 months before expiration.
