What does the Korean visa look like?
The South Korean visa consists of seven parts: visa number, status (e.g. short-term visit, medical, business, study, etc.), period of sojourn/stay, number of entries allowed (single, double, or multiple-entry visa), issue date, final entry date, and place of issue.
Your status is based on your visa type. Korea provides 15 types of visa for visitors.
