Yeah, the visa process is kind of a hassle, they take longer than they're supposed to. Likelihood of finding a part time job depends on your area, to be honest. You aren't allowed to work more than 20 hours a week on a student visa. However, many places here take advantage of illegal work by paying very low wages i.e 5RM/Hour and hire international students who work longer hours to earn more. So really, it depends.
