doctor
As a medical specialist, a doctor carries out the work of improving, maintaining and restoring human health by studying, diagnosing, and treating diseases, injuries, various physical or mental disorders. According to the Medical Law, medical personnel are divided into doctors, dentists, oriental medical doctors, midwives, nurses, and doctors are engaged in medical and health guidance. Those who intend to become doctors are required to obtain a license from the Minister of Health and Welfare after having passed a national examination for obtaining a doctoral license as a doctor of medical school or a medical graduate school who has graduated from a medical degree or a master's degree. However, a person who obtains a Korean nationality who obtained a doctoral license in a foreign country and obtained a green card can obtain the license through a prescribed test.
