How to obtain South Korean citizenship: What you need to know

Adam Rozsa

South Korea has had an industrial boom in the last decade, which has stabilized the country, grown its economy, and made it more attractive to foreigners.

What was once a country with very few migrants has become a hotspot for foreigners, because of their opportunity for jobs and newer immigration laws.

Whether you’re hoping to form a business, find a new job or just start a new way of life, this guide will walk you through the most important steps towards obtaining South Korean Citizenship.

If you’re unsure how you’ll handle your finances as a South Korean citizen, Wise can help you manage your money, and will give you the real exchange rate when you exchange South Korean Won.


Is it easy to get Korean citizenship?

There’s no way to sugar coat it; obtaining a South Korean citizenship is pretty difficult. As such, it’s considered easier to stay in the country on a permanent resident visa (known as an Alien Registration Certificate) instead, although that does carry its own restrictions.

For instance, once you obtain a long-term visa in South Korea, whenever you make a change in your lifestyle, you’ll need to update your Registration Certificate with District Immigration within 14 days of the change. This includes a new job, or a change of apartment. Our guide on renting in the popular expat town of Seoul may help you with this.

How can a foreigner get Korean citizenship?

In order to become a citizen of South Korea, most foreigners go through the naturalization process. There are three main ways you can become a naturalized citizen of South Korea: through residency, family (including a spouse) and business ownership. 

Korean citizenship through residency

If you’ve lived in South Korea for more than five years consecutively, you can consider applying for general naturalization. This type of citizenship only applies if you’ve never obtained Korean nationality in the past, and if you have no Korean family relations. To apply, you’ll need to meet all of the following criteria:

  • Be at least 20 years old
  • Have an Alien Registration Card
  • Have a Korean address on file
  • Be eligible to work in South Korea 
  • Be of good conduct – you'll be ineligible for citizenship if you have a criminal record 
  • Be able to maintain a living on your own (or you may be a dependent member of a family who can help you maintain a living) – this includes working professionals and retirees
  • Have basic knowledge on South Korea, including  an understanding of the Korean language, customs and culture

Korean citizenship through family

The second type of naturalized citizenship is simple naturalization, which is predominantly available to foreigners who are of South Korean descent of some sort. To be eligible, it’s crucial that you meet at least one of the following criteria: 

  • You have a parent who was a South Korean citizen in the pass
  • You were born in South Korea, with either of your parents also born in South Korea
  • You’re an adopted child of a South Korean citizen – you’ll only be eligible if you were not of legal adult age at the time of adoption
  • Your spouse is a South Korean citizen

In order to qualify for simple naturalization you must also meet the requirements of general naturalization, as listed above, however, you need only to have lived in South Korea for three consecutive years rather than five.

Korean citizenship through business ownership

If you’re looking into South Korean citizenship for business reasons, and you can invest 100 million KRW (approximately 79,000 USD) into your own small business in South Korea, you may be eligible for a D-8 Investment Visa.¹ But please note that the South Korean government requires proof that the business is viable when you renew the visa.

Does marrying a Korean give citizenship? 

As briefly mentioned above, you can seek citizenship through simple naturalization if you're married to a South Korean citizen. However, you must have maintained your marriage status for the past two or more years, and you’ll need to meet all the other criteria listed before you’re granted citizenship.

How to apply for South Korean citizenship? Step-by-step

The application process for South Korean citizenship is extensive. Your completed application must include the following:

  • An application form (this form is presented in Korean, not English)
  • One color photo of yourself
  • Your Alien Registration Card
  • A written statement for citizenship application
  • A statement of identity
  • A copy of your statement of identity (this one with a color photo attached)
  • A copy of foreign family registration or citizenship papers (if applying for simple or special naturalization)
  • A document outlining any dependents you may have (including children or parents)
  • Proof of financial stability

To prove your financial stability you may include a certificate from your bank showing you have a balance of more than 30,000,000 KRW, a certificate of employment or a document from the Attorney General proving you’re a dependent. You must also include two letters of reference from someone with a professional title. This can be a member of a government, a professor, a lawyer, an executive or manager, the chief of a department or similar. You must also pay a fee of 100,000 KRW (approximately 80 USD) for your application to be processed.

How long does it take to become a South Korean citizen?

Unfortunately, there is no clear-cut answer to this. It will depend entirely on the type of naturalization you're seeking, and therefore the documentation that's required from you. As with most application processes, even within the US, if the Immigration Office requires additional information to support your application, the process will take longer.

Once you’ve submitted all the necessary documents to the South Korean immigration office, you’ll need to take the written examination. This will be a 20-question multiple choice exam that will test your knowledge of South Korean history, politics, culture and customs. 

Following the multiple choice exam, you’ll need to attend an interview in order to test your proficiency in the language, as well as your attitude towards Korea and liberal democracy. To pass this section, you must be at about level four on the Test of Proficiency in Korean (TOPIK).² This test is notoriously difficult – you even have to sing the first four verses of South Korea’s national anthem, without reading the lyrics off of a page. 

Following your interview, it typically takes one to two months for the immigration office to issue a decision on whether to give you permanent residency.³

Does Korea allow dual citizenship?

In most cases, South Korea requires that you renounce your foreign citizenship in order to obtain South Korean citizenship. However, there are some exceptions to the rule. It’s possible to maintain dual citizenship if you:

  • Are married a South Korean national
  • Have what’s considered to be “outstanding talent”, for instance in science or sport 
  • Have made a significant contribution to the Republic of Korea
  • Would find it difficult to renounce your foreign citizenship due to stringent rules imposed by your home country
  • You were formerly a Korean national and want to reinstate your citizenship

If you're granted your citizenship, you'll have to pledge not to exercise your foreign citizenship in South Korea.⁴

How can I get a South Korean passport?

Once you’ve been granted South Korean citizenship, you can apply for a South Korean passport by following these steps:

Step 1. Make an appointment at your closest South Korean embassy or consulate – South Korean passports use biometric data so you’ll need to make your application in person.⁵

Step 2. Attend your appointment and take the relevant documentation with you. This will include two passport photos and proof of US residency, but the requirements depend on individual circumstances.

Step 3. Pay the fee – the standard fee for a Korean passport is $53 and typically needs to be paid in cash.

Step 4. Your passport should be issued to you within 3-4 weeks.⁶
