How to Apply for Korean Naturalization?

This blog is about How to Apply for Korean Naturalization for foreigners married to a Korean. This is called Simple Naturalization. 

There are different ways to acquire Korean citizenship but in my case, I got my citizenship through Simple Naturalization (maintained marriage).  But if you think it was easy to obtain, it’s not. I think having a permanent residence visa is easier to acquire than citizenship. Aside from the application, you need to wait at least 6 months to 1 year for approval. It’s too long to wait right? That’s why every applicant must patiently wait.

Before I apply for my citizenship, I took the program which is called KIIP, or Korean Immigration and Integration Program. This program manages by Korean immigration and there are 5 levels to pass to be eligible to apply for Korean naturalization.

I took a level test in 2017 and passed level 3. I finished the program in 2 years and passed my citizenship exam last 2019. In January 2020, I submit my application, it was approved last September 28, 2020, and I got my ID was released exactly on my birthday.  So here are the ways how to apply for Korean naturalization or citizenship.

How to Apply for Korean Naturalization?

There are two different ways how to apply for Korean naturalization, the first is a direct application and the second is studying the KIIP course.

I. Direct Application

Some of the applicants prefer the direct application especially if they are working moms. The difference only with the application through KIIP is the applicant first submits documents, pays the application fee, and waits for the schedule of the interview. The applicant needs to wait about 4 to 6 months before the interview. While waiting for the interview schedule the applicant needs to prepare or study to be able to pass the interview.

The interview consists of reading the follow-up questions, 15 questions that need to be answered, and singing the Korean national anthem, Aegukka.

TIP: If you don’t know the answer just be honest.

II. Application through KIIP

Passing the KINAT or Korean Immigration and Naturalization Aptitude Test will give you the chance to apply for Korean citizenship. You need to print the certificate and include it in your application when you submit your documents. For the list of requirements needed you may visit, the Hi Korea website.

  2. While reading your blog, I was thinking about a friend who would absolutely love to read this. She declared she’s going to marry a Korean and will live there. She’s going to want to know this.

  3. This is a very helpful blogpost. How was the exam? Do you have any tips on how to study and pass it?

    1. Its really hard to apply for citizenship in any country. So many requirements plus the waiting game is so long. Kuddos to you hard work and patience really pays off. Congrats!

  4. Wow! ang tagal din ng process at mahirap nga talaga since ang daming kailangan gawin, including learning, but of course you really need to know how to speak and understand their language and culture for you to be a citizen. What do you call your visa while you were waiting to be granted citizenship? congratulations, pa 1 year ka na ding citizen! dual ka?

    1. Spouse visa (F-6) ung visa ko nung pumunta ko dito then hindi pa ako dual kasi hindi pa ko nakapag apply sa Philippine Embassy. Pag okay na siguro corona saka ako mag apply

  5. Congrats sis! You are now fully entitled and enjoy your full Korean citizenship rights! Here in Australia, citizenship application wasn’t difficult (except the waiting time for approx. 4 years!), must passed at the minimum of 75% score for the Australian citizenship exam, and of course must know how to speak and understand basic conversation English. The last rule was been added recently, this is to avoid the situation of getting involved to any kind of abuse (including domestic / relationship abuse) especially for couples.

    1. If you mean waiting for the result of your application, I think you should be here in Korea because if there’s something wrong with the papers you have submitted they’ll gonna call you.
