The main 3 pathways to citizenship in South Korea
If you relocated to Korea and aim to obtain citizenship in 2025, here are your options:
- naturalization;
- paternity or ancestry, however, due to the fact that it can only be acquired through the father, it is often referred to as the first term;
- marriage.
For those who have lost citizenship there is also the process of re-acquisition. However, you should know that Korean dual citizenship is not accepted, should you plan to retain two or more nationalities.
If you fall under any of these categories, waste no more time and get in touch with our immigration lawyers in Korea for guidance. We can also help you open a company in Korea and start your business activities there.
Korean citizenship by naturalization and its requirements
Naturalization is the safest way to obtain citizenship in Korea in 2025, as it implies meeting the following requirements:
- holding permanent residency in South Korea for a minimum period of 5 years;
- being an adult, according to the Civil Code in South Korea;
- having a clean criminal record during your stay here;

Citizenship by simplified naturalization in Korea
When it comes to naturalization, apart from the general one, there is also the simplified citizenship. Its main advantage is the requirement to have a permanent residence permit in South Korea for minimum 3 years prior to the application. However, there are also conditions to meet, among which:
- the applicant must be an adult at the time of the application, in accordance with the Civil Code;
- he or she must also have complied with the Korean laws;
- the person is also required to have sufficient funds to sustain him/herself, however, dependents of other family members who make enough money are also accepted;
- the applicant must also have a good knowledge of the South Korean language, culture, and customs.

This pathway can also be used by people who immigrate to South Korea and:
- have given up Korean citizenship and want to obtain again;
- were born in Korea, their parents left the country with them and decide to return;
- were adopted by Korean citizens and were adults at the time of adoption.

Another way to secure citizenship in Korea is through special naturalization. This type of nationality covers the following:

- They have either a parent or a grandparent of Chinese origin who applied for Korean citizenship, but died before receiving it.

Please note that for each type of application other requirements apply, including financial ones, such as those related to the minimum income of the candidate. In this case, we invite you to discuss with our accountants in Korea for clarification.
