Good day, I am a South African Citizen staying in Busan,

Tyron, if you will stay with your friends, I advise you to get an invitation letter from them, so that hotel bookings and transportation poof are not required. You need to prepare your passport, passport copy, application form affixed with a recently-taken bare-headed photo, and the invitation letter. The letter should include your date of arrival and departure, visit plan and both of your particulars. You can apply from the CVASC in Busan.
