South Korea has the third most powerful passport in the world. Its passport holders have the right to visa-free entry to 190 countries, including the USA and 43 European countries.

How to become a citizen of South Korea? Citizenship of the Republic of Korea is granted first of all to anyone born in the country, as well as former citizens and their descendants. However, foreigners also have an opportunity to get a Korean passport. Read on to find out what you need to do to become a South Korean citizen.


How to obtain Korean citizenship by naturalisation? There has been a rapid increase in the number of naturalised foreigners in South Korea since the 2000s.

Applications for citizenship are handled by the Department of National Affairs. It has 19 offices in South Korea: in Seoul, Busan, Incheon and 13 other cities across the country

There are three types of naturalisation in South Korea:

General Naturalisation

How to become a Korean citizen by general naturalisation? General naturalisation is stipulated for foreigners who live in the country with permanent residency status, in other words, with an F-5 visa, for five years or more. During this period you can stay abroad for a maximum of 30 days.

Applicants must comply with laws and regulations, as well as the requirements on proper conduct established by the Ministry of Justice; for example, you cannot photograph people without their express consent, and you must also cover your upper body, including your shoulders, when in public places. The import, storage and distribution of pornographic literature in South Korea, as well as printed materials produced in North Korea, is strictly prohibited.

In addition,  general naturalisation stipulates knowledge of the Korean language and the basics of South Korean culture. All the applicants pass a mandatory test which evaluates the extent of social integration in Korean society.

What other requirements are there to get South Korea citizenship? The financial solvency of the applicant is also important. Future citizens of the Republic of Korea (or a relative living with them) must have a bank balance of at least KRW 60 million (about USD 45,000). The applicant must own real estate worth the same amount.

To obtain citizenship in the Republic of Korea, the applicant must also provide a letter of recommendation from two or more citizens who have a good reputation in society.

Finally, there are also age requirements. You must be of legal age, in other words, over the age of 19, to become a South Korean citizen. However, immigration lawyers advise that you should only apply after you have turned 20.

Simplified and Special Naturalisation

The same requirements will apply to anyone naturalised under the simplified procedure, which reduces the total period of residence in the country to three years. How to become a citizen in South Korea by simplified naturalisation? The simplified naturalisation procedure is available to:

  • Ethnic Koreans who have the citizenship of another country
  • People adopted by Korean citizens before they reach the age of 19
  • The spouses of Korean citizens (you can read more about this type of naturalisation in the section Citizenship by Marriage to a South Korean

People born in South Korea, as well as children discovered in the country without parents, are granted citizenship immediately. In addition, anyone born to a South Korean parent automatically becomes a citizen.

How to get South Korean citizenship by special naturalisation? In the case of special naturalisation, no mandatory period of residence in the country is stipulated. This procedure is intended for the children of South Korean citizens who lost their Korean citizenship for some reason.

Anyone who has exceptional abilities may use the special naturalisation procedure if they have already made a significant contribution or are about to make a significant contribution to the development of any industry in South Korea. Their applications are not forwarded to the immigration offices, but instead directly to the Committee on Citizenship and the Ministry of Justice.

For example, Ra Gun-ah, born Ricardo Preston Ratliffe, US-born player of the men's national basketball team of the Republic of South Korea, obtained dual citizenship in 2018 through the special naturalisation procedure.

What else opportunities are there to get nationality of South Korea? As well as the spouses of Korean citizens, their widows and widowers, as well as divorced spouses raising minor children who were born during the marriage are eligible for citizenship.

Citizenship for Overseas Koreans

How to become a south korean citizen if you are an overseas Korean? The South Korean authorities are trying to attract respectable ethnic Koreans from all over the world to the country. For this purpose, a programme granting citizenship to overseas Koreans, which has existed since the middle of the 20th century, is updated regularly.

For example, a Special Act on Assistance to Sakhalin Koreans has been in effect in South Korea since 1 January 2021. According to this document, Koreans who were born on the island or settled there before 15 August 1945, as well as their spouses and family members up to and including the fourth generation, are eligible for South Korean citizenship.

Dual Citizenship in South Korea

How to become a citizen of Korea and save the current nationality? The South Korean Nationality Law does not allow dual citizenship for naturalised people. You have to renounce any foreign citizenship within a year of receiving a passport. If you fail to do this in the given time period, you will lose your South Korean citizenship automatically.

However, the law provides exceptions to this rule. So who can take an advantage of dual citizenship in South Korea? The following individuals are eligible for dual citizenship in South Korea:

  • the foreign spouses of South Korean citizens
  • anyone who previously had Korean citizenship, but then lost it and was the citizen  of another country at the time of the receipt of a South Korean passport
  • anyone adopted while a minor by foreigners who lived in other countries before returning to South Korea
  • anyone who had Korean citizenship, but lived abroad for a long time and returned to South Korea at the age of 65 or older
  • people who cannot renounce their current citizenship due to foreign law (in this case, a special decree of the President of the Republic is required)

All the above must submit a letter of commitment to the Ministry of Justice, stating that they will not use their foreign citizenship in South Korea. In this case, they will become legal holders of dual citizenship.

Loss of South Korean Citizenship

Why can I loose a citizenship of South Korea? A South Korean citizen who obtains the passport of another country loses their Korean citizenship automatically. However, there are exceptions to this rule in the nationality law.

The following categories may keep their South Korean citizenship:

  • anyone acquiring foreign citizenship through marriage to the citizen of another country
  • Korean spouses and the minor children of anyone who acquired foreign citizenship and lost their citizenship as South Korean citizen if they also obtained foreign passports
  • anyone adopted by foreigners who received the citizenship of their adoptive mother or father
  • Korean citizens who acquired foreign citizenship by mistake or as a result of  fraud

Anyone included in one of the categories listed above must notify the Ministry of Justice of the Republic within six months of the date when they obtained foreign citizenship that they intend to retain their Korean citizenship. If the Ministry of Justice is not notified within this period, their Korean citizenship will be cancelled automatically.
