Naturalization Aptitude Test (KINAT)

10. Frequently Asked Questions {#section-10}
Q. What happens if my alien registration card expires while my naturalization application is pending? A. Your visa status is maintained during the review period after submission. However, you should still renew your alien registration card separately to keep it valid.
Q. Does TOPIK Level 4 exempt me from the naturalization test? A. Yes. TOPIK Level 4 or higher waives the Korean language section of the naturalization test. You must still take the Korean society comprehension section separately. KIIP Stage 5 completion waives both sections.
Q. Can I travel abroad while my naturalization application is in progress? A. Yes, but extended absences may affect the residence period calculation. It is advisable to remain in Korea ahead of your scheduled interview.
Q. How long does it take to get a Korean passport after naturalization? A. After the oath, complete resident registration → resident card issuance (~1 month) → passport application (~1–2 weeks). In total, expect to receive a Korean passport approximately 1–2 months after the oath ceremony.
Q. Do I need to obtain F-5 permanent residence before applying for naturalization? A. No. You may apply for naturalization directly without holding an F-5 visa. In practice, many applicants obtain F-5 first, but it is not required.
