Hi all, last year I had to enrol in a diploma course to extend my visa because my sponsor was delaying my last semester's tuition fee ( student visa expired, couldn't apply for 485). As a consequence, I had to get CoE from a college to have a valid visa. I paid their first-semester fee, however, not the second one because I had already applied for my 485 and got it shortly after. Now, they are demanding the fees from me. Apart from the legal point of view, which I think I should pay the fees, my question is: would the immigration office cancel my 485 because my student visa's conditions weren't met? I didn't pay and didn't go to classes. They emailed me that they would report me, not knowing that I'm not on a student visa anymore.
