Is it worth taking Computer Science Undergraduate degree in South Korea?

Hi, I am a International Student wanted to pursue my undergraduate degree in South Korea. But lately while researching about studying or student life in South Korea I saw a lot of international students actually going back to there country before completing their course. Most of them had very bad experience. Some are also saying a degree from a Korean university only worth in Korea if you so if you want to settle in Korea then only study in Korea. But some are also saying that their experience wawasn't that bad. Some are saying even in full english course they can't understand professors english or professors are teaching in Korean. I know everyday Korean but I don't know much tech or bookish language.

Please help me out.
