The national health insurance refers to a social insurance that aims to promote the stability of the life of people by distributing the burden of medical costs among all subscribers through compulsory subscription. All subscribers other than employee insured and their dependents are classified as self-employed insured. All foreign nationals and overseas Korean nationals who stay in Korea for six months or longer will also be obligated to subscribe to health insurance as self-employed insured from July 16, 2019, and they will be offered equal benefits as the citizens of the Republic of Korea.
