There is a resentment of international students who get partway through a course and then cry poor. Our university (and probably others) held a big campaign during COVID lockdowns to donate money, clothing, groceries to international students who couldn’t work and couldn’t get back home…
Understandable. I wasn’t aware of international students struggling when I was at uni (doubtless there were some, I just didn’t see them). COVID lockdowns and border closures were an extreme situation, and I would think there were probably some students who would have been fine normally but didn’t have the extra resources to deal with that large a curveball.
Generally, I think the rules around student visas are reasonable. You’re here to earn a degree, and that needs to be your focus… Not holding down a full-time job to put a roof over your head. Studying abroad is a luxury. (Of course, universities like international students because $$$…)
