What are the requirements for Korean naturalization, and must I give up my original citizenship?
I have lived in Korea for many years and want to become a Korean citizen. What are the requirements for naturalization? Do I have to give up my original citizenship?

Naturalization generally requires 5 years of continuous residence (less for marriage or special cases), permanent residence (F-5) status for general naturalization (required since 2018), proof of livelihood, good conduct, and passing a naturalization test plus interview on Korean language and society, which the KIIP program can exempt you from. Korea has historically required renouncing your original citizenship, but there are exceptions where dual citizenship is allowed (for example marriage-based and certain talent cases) if you pledge not to exercise the foreign nationality in Korea. The process takes a long time, often over a year, so gather documents early and check the current rules with the Korea Immigration Service.
