1. If he doesn't sign for you, it means that you can't graduate normally, or you can only quit school without a degree certificate. The influence on the tutor is the reputation of his future enrollment (plus your own good work, which fully meets the graduation requirements of the laboratory or school), which is very important for a laboratory. Our laboratory spends a lot of money to promote it every year.

2. Any tutor hopes that his students can graduate smoothly unless they encounter extreme circumstances, such as students don't want to graduate themselves, or students make extremely serious mistakes in the learning process. According to the personal experience of our laboratory, if a student can't finish his thesis or meet the requirements of school graduation for various reasons, the tutor is very painful.

Your problem now is to over-amplify the consequences of your withdrawal from the master's program. I guess you are not only worried about whether you can graduate (I also had this idea at the beginning), but also worried that the teacher will embarrass you. In fact, the tutor really can't bear to do these things. I hope you put your mind right and try your best to meet the graduation requirements. If this happens, you can declare it to the college. This is because students quit the master's program and don't sign it.
