If you just want to know the former, it is easy. Ask your school's student status management department (usually the Academic Affairs Office or the Student Affairs Office) or visit the school homepages of these two departments. There are usually downloads of application forms for suspension or withdrawal from school on the website of the department (generally, you can also go to the department to get them yourself). After you get the form, just fill it out and sign it. The general contents include: personal basic information, reasons for dropping out of school, my signature, parents' signature, head teacher's counselor's signature, department head's signature, school related departments' signature, school leaders' signature, etc. If you drop out of school, you will be asked to go through the formalities of dropping out of school and transfer the file. If you drop out of school, it is usually one year, limited to two years (that is, you have to go through the formalities of resuming or continuing to drop out of school after one year, otherwise it will be treated as automatic withdrawal).
If you want to know about the latter, it's not a trivial matter for individuals to drop out of school, and in order to avoid conflicts, parents' signature is generally indispensable. Even if it is inconvenient for parents to travel abroad, they will call their parents before they can handle it.
Your thoughts are understandable, but your parents' thoughts also hope you can understand them. After all, you worked so hard to go to college. If you don't study, you won't study. As a traditional parent, it is hard to accept. On the one hand, you feel that years of hard work have been wasted, and there may be a face problem. In addition, you should also think carefully. After all, you have entered the university, and you are only a few years away from graduation. Really can't wait these years? If you can wait until graduation, that is, you will have more diplomas, and you will be able to do your career more smoothly in the future without making your parents unhappy. Is it more appropriate? I hope you can weigh it yourself.
If you finally decide to come out early, then I suggest you drop out of school. After all, if you really get in touch with the society within this year, there is still a chance to go back to school, in case your mentality changes, dropping out of school is irreversible. As for parents, you can tell them to quit school first, behave resolutely, and then take a step back when the time is ripe and say that they can quit school. This is psychologically easier to succeed than simply saying that you can drop out of school.
