Hello, you can apply to transfer to the junior year of Ewha Women's University in Korea after your sophomore year, or you can apply for the senior year directly after your senior year. Graduate students generally apply 6- 10 months in advance. If you don't have a language foundation, apply for language materials first: graduation certificate, report card, household registration book, ID card, parents' employment certificate, income certificate, deposit certificate, passport, photo and self-introduction. As for your major, you can change your major, but you have to think about whether you can keep up with cross-disciplinary study. The total sales expenses of schools in Seoul should be around 70,000-80,000 a year.

You can teach yourself Korean during college, or enroll in a Korean training class, and then go to Korea for half a year. This will not waste time, and your Korean score is high, which will help you apply for scholarships. Korean graduate students generally require a four-level application, and individual majors require a five-level admission. Personally, I think these two majors will do well in the future, depending on which one you are more interested in. I hope I can help you. As for the Korean guarantor, the general intermediary will help you find a good guarantor, don't worry.
