The first point, which is also very important, is that Korean must pass at least Band 4. But now many schools require Grade 5.

Secondly, I speak English better, because some courses are taught in English.

If your Korean is not good, you can study in a language school for half a year before applying, which is no problem.

Third, just like applying to other schools, prepare deposit certificates and the like.

I am studying at Korea University now. If you have any questions, you can call South Korea, and a teacher from China will seriously answer your questions. If you want to apply now, you can only apply in March next year.
