According to the Korean military service system, Korean men must perform military service, and mixed-race children are no exception. However, if the mixed-race children have other nationalities or permanent resident status, they can apply for extension of service or exemption from service. The specific situation needs to be decided according to the Korean military department.
It should be noted that Korean mixed-race children must undergo a physical examination at the age of male 19 to determine whether their bodies are suitable for service. If you have a serious illness or disability, you can apply for exemption from service through the corresponding medical certificate.
