Parents immigrate to Korea, can children attend high school in Korea? Is the learning progress much worse (understand Korean)?

Parents go to Korea. Of course, children can go to the local high school with them. Learning progress is not as simple as China people think, if you get good grades. You should be able to catch up quickly when you are a tutor, depending on your Korean level. So you'd better watch more Korean novel news and so on. Use Chinese as little as possible. If you just live, you can be an international student after graduation. It is easy to get into a good university. But try to keep good grades, and the university can catch up quickly.
