Am I allowed to do a part time job?
If you have a pre-college visa, after receiving “Permission to Engage in Activities Outside the Scope of the Visa” from the Immigration Authority, then you will be eligible to work for up to 4 hours per day. It is not possible to receive this permission soon after entering school. Following entry on a student visa, you may apply for this permission and a test, if you pass the test given by school one month later.
