School took my passport to take care of residence permit, but I need it back
Hello!
I came to study in a Chinese University with an X visa a few weeks ago. The school took my passport to take care of the residence permit. They said it will take approximately 50 days. Now, 3 weeks later, it turned out that the teaching in this "university" is nothing what I expected and I feel like I'm wasting my time here. I would like to get a flight back home within a few days, but the problem is that the school holds my passport. I know that I do have the right to get it back whenever I want, it is legally mine. Will this cause any trouble? I know that my X will get cancelled but that is okay, I wont be needing it anymore after going home. My main concern is that how fast will they hand my passport back, and is there any chance that they might possibly refuse to give it back to me? I mean, what if there was a death in my home country or some other really urgent reason for me to leave the country?
