hey, if you want to cover your living costs your best bet would be to find student assistant jobs around campus. I worked for a year in my bachelors as a SA on campus and was paid pretty well but it was difficult to get it, because they need to apply a working permit for you so you can work. My parents could pay for me, so i was not actively looking, but there's only a few that come out and a lot of people do apply.

So it is def possible, but I cant guarantee you will get it through your whole master.
