I have a friend who is currently a student with a student permit that only allows them to work 20 hours per week however they also got approved for a closed work permit with a production company. They recently applied for an advertising job and was chosen for the job. They would like to know if its possible for them to take the advertising job via the student permit without causing any issues or conflict with their closed work permit like working 20 hours different from her closed work permit. Any help would appreciated, thank you.
