Marriage-Based Naturalization (배우자 간이귀화)

Marriage-based naturalization is located at 국적법 제6조제2항 (within the 간이귀화 / facilitated-naturalization article) — there is NO separate 'marriage' article. An alien whose spouse is a ROK national may naturalize WITHOUT meeting 제5조제1호 (5-year domicile) and 제5조제1호의2 (PR prerequisite) if they fall into one of four 제6조제2항 sub-categories. The spouse-of-Korean route is structurally a sub-type of facilitated naturalization, not 제7조 special naturalization (the 'Article 7 for spouses' framing is a refuted model error, fabrication catch A4).

• Naturalization takes effect at the OATH-AND-CERTIFICATE moment, not at the grant of permission: a person who obtains naturalization permission under 제4조제1항 acquires ROK nationality at the time he/she takes an oath of citizenship (국민선서) before the Minister of Justice AND is granted a certificate of naturalization (귀화증서), per 국적법 제4조제3항. The Minister may exempt a person from the oath where age or physical/mental disability prevents understanding it. Per 제4조제4항, the head of a regional immigration office may receive the oath / grant the certificate on the Minister's behalf. This oath-timing regime was INTRODUCED by Act No. 15249, effective 2018-12-20. (The oath provision is 제4조제3항, NOT 제5조.) - Naturalization-test mechanics (귀화적격심사 / 종합평가 + 면접심사) operationalize the 제5조제5호 basic-knowledge and 제5조제3호 good-conduct requirements at the Enforcement-Decree / Ministerial level: the eligibility examination is conducted as a written comprehensive evaluation (종합평가) and interview (면접심사) with a pass mark of 60 out of 100 (60점 이상); completion of the Social Integration Program (사회통합프로그램, KIIP) advanced level can exempt the written test. The test structure and pass-mark are NOT in the Nationality Act itself — the Act states only the substantive 제5조제5호/제3호 requirement.
