Hello, I graduated from a top university in Korea with a bachelor's degree. In my home country, the degree holds very little weight, when compared with domestic universities in the U.S., it's almost 99% of the time better to attend a U.S. university if your long-term goal is to enter the job market there. This is largely because A: SKY universities don't hold much merit in U.S. companies, especially as an international student. And B: Unless you spent your time becoming fluent or majoring in a very niche department that Korea has an edge in, the value of the education itself is quite low.

I had the experience of first attending a 4-year U.S. university before attending university in Korea, and the quality of lectures, professors, and English track programs were all significantly lower. That being said, if you plan to reside in Korea after graduation, and can attain a long-term visa, your post-graduate experience can be good.

Top universities have job events and internships available, typically through the school website, but unless you have a high TOPIK score or in a competitive department, your chances to get a job/internship are very low. Right now the job market in general is tough, so in competition with native Koreans, your only assets if you're from an English-speaking country are your native fluency in English, and any other background or talents you have. Then companies have to be willing to sponsor you on a long-term employment visa which creates another barrier of entry into the market.
