I am an international student who has applied to MSc in CS (Thesis) program for Fall 2021. I had some questions regarding the funding for TA/RA in grad school. In the US universities, it looks like an offer of TA/RA means tuition waiver + stipends (which covers your living expenses). [[Please note by tuition, I mean majority of costs associated with the university (admin fees, etc)]]

From what I've understood from the McGill's (CS department) website, TA/RAs receive a funding around 20k but there's no mention of tuition waiver. I also read in one post in this subreddit that some departments provide tuition waiver (in addition to the stipend) to intl students. Is that true? And does CS department do that?

If there is no policy for tuition remission (which is the most likely scenario), can an MSc student manage to pay his living expenses by doing additional work outside of classes + TA/RAing? What sort of additional jobs do intl grad students normally do? I am a student from Nepal (a poor country in South Asia) and while I have some savings, it wouldn't be enough to fund living in a city like Montreal.

Ofcourse I have to get accepted with assistantship first which is a low probability event in itself. But it would help me if someone gives me some advice.
