Can I stay in Korea to work after I graduate?

Changing from a study status to an employment status is possible in principle, but it depends on your degree, the job you are hired for, and the employer meeting the requirements. It is a change of status of stay handled by the immigration authority, not something the university decides. Because the conditions are updated regularly, please rely on the official immigration guidance rather than on second-hand accounts. The "Permission for activities outside status" card in the Learning Centre is the closest official starting point in the app. Practical advice while you study: keep your grades and attendance clean and build up your Korean level. Both are looked at when you change status.
