📌 Summary in 3 lines - General naturalization requires permanent resident (F-5) status + at least 5 years of continuous residency as a basic requirement, and proof of financial stability can be demonstrated through income, financial assets, or deposit/security money. - Documents often get stuck in native country documents — requiring apostille, Korean translation, and name spelling consistency. - Applications require the applicant's direct attendance, so plan your schedule backward from the reservation date.

I am an administrative agent based in Songdo, Yeonsu-gu, Incheon. Here's an anecdote I thought I'd share with my neighbors. 😊
First, I received twelve photos via email. Passport, permanent resident card, birth certificate, bank statement, and lease agreement. She was someone who had gathered the general naturalization documents herself. Before I met her in person, about half of the checklist was already completed.
However, the twelfth photo wasn't a document. It was a handwritten note with Cyrillic and Korean characters – her grandmother's carrot kimchi recipe. 🥕 It was a photo she was sending to her mother.
The applicant was a 30-something-year-old woman of Korean descent, third generation, from Uzbekistan. She came to Korea at 20 and has lived in Yeonsu-gu, Incheon for 9 years, working as an office clerk at a logistics company and already holds permanent resident (F-5) status. She also sends her mother in Tashkent money for medicine every month.
She has no problems with her life even with permanent resident status. Still, she said she wanted to cast a vote in the next presidential election in this country. It was a country her grandmother always talked about.
## 1. The Two Things Missing from the Twelve Photos 📎
Checking the checklist revealed two missing items.
- Criminal Record Certificate from Native Country — it wasn't in the photos.
- Birth Certificate — the photo was from a copy used when applying for permanent residency several years ago. The original had already been submitted at that time, and there was no Korean translation.
It’s easy to think that the same documents will suffice as when applying for permanent residency, but naturalization documents are different. Native country documents must be issued locally, have an apostille attached, and then be translated into Korean. Uzbekistan is a member of the Apostille Convention, so it is processed with a local apostille instead of consular confirmation.
Therefore, the documents were divided into two bundles: those that can be obtained directly in Korea and those that must be obtained and sent from the local area. Because the process that takes longer should be started first to shorten the overall schedule.
## 2. Financial Stability Wasn't Just One Path, Even with Insufficient Income 🏠
Article 5 of the Nationality Law stipulates general naturalization requirements as 5 years of continuous residency, eligibility for permanent residency, and the ability to maintain a livelihood based on one's own assets or functions, or on the support of family members living together. In other words, it looks at whether you have the economic foundation to support yourself in Korea.
She intended to obtain a income verification certificate from the tax office. The problem was that she took a break for four months when she changed jobs last year. While it was sufficient when calculated as a monthly salary, her annual income was slightly below the previous year's per capita Gross National Income (GNI).
Financial stability for general naturalization is not proven with just one document.
- Income verification certificate above the previous year's per capita GNI
- Financial assets of 60 million KRW or more (deposits, savings, etc.)
- Real estate or lease deposit/security money of 60 million KRW or more
While her bank deposits were below the standard, her lease deposit/security money for a villa in Yeonsu-gu exceeded 100 million KRW. So we switched to the deposit/security money path.
However, a single lease agreement was not enough. She renewed the contract two years ago and increased the deposit/security money, but the original contract stated the amount before the increase. To prevent the officer from questioning the amount, we created a bundle including the original contract + the renewal contract + confirmation of lease + bank transfer record of the deposit/security money. We also confirmed that the tenant was solely in her name.
The standard amount and accepted documents can change, so it’s safer to re-confirm the guidelines at the time of application.
## 3. One Letter in Passport Spelling
It turned out that a few years ago, when they renewed their passport, the spelling of their English name had changed by one letter. The first letter, Y, became I. Their alien registration record, bank, and company documents showed the old spelling, the new passport showed the new spelling, and the birth certificate was in Cyrillic script. It was as if one person's name was written in three different ways.
So, we prepared two things:
- To submit a copy of the old passport together to show the reason for the spelling change.
- To inquire with the Embassy of Uzbekistan in Korea about obtaining a certificate of identity.
The translation also lists the three notations side by side.
They decided to delegate the local documents to their mother in Tashkent. They sent a power of attorney, notarized in Korea, and had the birth certificate reissued and the criminal record certificate issued, along with an apostille, all locally. Local procedures vary from country to country, so it's a good idea to check with the embassy beforehand.
During a video call, their mother showed them an envelope, and they immediately asked if they had received the recipe photos.
## 4. Counting Backwards from the Reservation Date, and After Approval 🗳️
It is impossible for anyone to submit a naturalization application on someone else's behalf. The applicant must personally go to the Immigration Office and undergo identity verification. What we did was to check eligibility, review and translate documents, make a reservation, and prepare for the interview.
The schedule was planned counting backwards from the reservation date. After subtracting the period for international postal delivery of local documents and the time required for translation upon arrival, there was only about ten days of leeway.
The fact that they had completed Stage 5 of the Social Integration Program (KIIP) before applying for permanent residency was also helpful. Since graduates are exempt from the naturalization comprehensive evaluation (written), we included the certificate of completion.
The application was completed on the reserved date. The review continued across the year, and the email notifying them of approval arrived one late autumn evening.
Approval is not the end. A pledge of allegiance and the presentation of a national certificate must be completed before naturalization is finalized. Also, according to Article 10 of the 「Nationality Act”, foreign nationality must be relinquished within one year from the date of acquisition of Korean nationality (renunciation of foreign nationality is possible only in some cases stipulated by law). If this period is exceeded, Korean nationality will be lost. We advised them to find out about the relinquishment procedures with their country's embassy in advance.
The last line of the email read: "I'll stand in line to vote in the next election." A few days later, a jar of seasoned carrot kimchi arrived at our office.
## 5. General Naturalization Checklist
① Permanent (F-5) residency status and five years of continuous address are correct. ② Path to demonstrating financial self-sufficiency — Income verification (GNI per person of the previous year or more) / Financial assets of 60 million won or more / Real estate or lease deposit of 60 million won or more - choose what applies to you. ③ Documents from your home country — Birth and family relationship certificate, criminal record certificate with apostille (or consular confirmation) + Korean translation. ④ Name spelling — If the spelling on your passport, alien registration, and home country documents is different, prepare an old passport copy and a certificate of identity. ⑤ Count backwards from the reservation date — Don’t forget to include the KIIP certificate of completion.
Required documents vary depending on nationality and residence history, so individual verification is necessary for each case.
