International students in Korea: Before starting a part-time job, make sure you have permission. Students on D-2 (student) or eligible D-4 (language training) status generally need to obtain permission for part-time employment from immigration before starting work. Working without the required permission can lead to immigration penalties and may affect your future visa status. Always check your permitted working hours and eligible workplace before accepting a job, as the conditions can differ depending on your visa, Korean-language level, and study program.
