A multicultural family means a family composed of an immigrant by marriage, a person who obtained permission for naturalization, or people who have acquired nationality of the Republic of Korea from the time of birth. Multicultural family members who raise children born in de facto marital relationships with a citizen of the Republic of Korea may also receive supports pursuant to 「the Multicultural Families Support Act」. A foreigner who has not ever acquired nationality of the Republic of Korea may acquire nationality of the Republic of Korea by obtaining permission for naturalization from the Minister of Justice. Naturalizations shall consist of general naturalization, simplified naturalization, and special naturalization. A foreigner who has reported a marriage with a Korean-national spouse may acquire nationality of the Republic of Korea more easily through simplified naturalization.
