I am a remarried immigrant woman living in Korea. My son, born to my ex-husband, is in third year of high school, so he plans to go to university next year. 

His nationality is not Korean. I would like to know how my son can prepare for admission to a Korean university as a foreign student. I wonder what documents he would need to get in high school and how to prepare for college.

Please let me know if there are any benefits that foreign students can receive after graduating from a Korean high school. I'm frustrated because I don't know what to prepare now.
