Study visa

You mean Student visa (D-2)? It can be acquired at a Korean embassy or consulate in your home country. You need Certificate of Admission from the school that you applied, in advance. As far as I know 😅

If you have the funds, you could start by studying at a language school in Korea (I did this way) to immerse yourself in the local culture. Depending on your Korean language skills your next step is to pass the Korean Language Exam (TOPIK 4) for school admission, and then you’ll be good to go! You can also try some Scholarship programs like GSK to speed up the process of getting in the school and also lesser financial strain... its a lottery though Hope it answers your question
