How to Extend your Canada Study Permit
The Canada Study Permit is valid for the time that you are studying and an additional 90 days to give you time to prepare to leave Canada. However, if you see that your study permit is close to expiring and you still have to attend your school to get your degree, then you must apply for extension.
You must submit an application to renew your study permit at least 30 days before it expires. You can check the expiry date which is located in the top right corner of the study permit. Before you apply for extension, you must make sure that your passport is still valid. You cannot get an extension if your passport has expired and if you travel out of Canada with an expired passport, you will not be allowed to enter again.
If you are planning to travel outside of Canada and your study permit is close to expiration, you must first apply for it and then travel. Do not leave Canada if your study permit is close to expiry because the Canadian authorities will not let you back in.
If you apply for an extension of your study permit and during the time that the application is being processed, your old study permit expires, you will be allowed to stay in Canada until a decision is made on whether to allow your renewal or not.
If your study permit has already expired and you have not applied for an extension, then you will have to leave Canada. Then from outside of Canada, you can apply for a new study permit or for the restoration of your status as a student.
