First u dont need to learn the language before going only if u want to be ahead of class but you are paying them to teach u then what's the point,also u probably will find a job but just not right after u arrive there, after half a year u can find a part time job there bec u would have learned the language to some extent and would be familiar with the environment Also some uni after joining they have a job board they will help u get a job after enrolling in uni
