Permanent Residency & Citizenship in Korea

A Practical Guide for Foreign Residents

Korea's F-5 Permanent Resident status is designed for foreign nationals who meet specific immigration requirements and wish to live in Korea on a permanent basis.

Unlike temporary visas, F-5 status provides much greater stability of residence. However, there is no single F-5 route for everyone. Eligibility depends on factors such as your current visa, length of residence in Korea, family relationship, professional qualifications, investment, income and other requirements.

Korean immigration law provides numerous F-5 categories, so applicants should first determine which permanent-residency category applies to them before preparing an application.

Major Routes to Permanent Residency

1. Long-Term Residence Route

One of the standard routes applies to adults who have lived in Korea for five years or more under specified eligible statuses.

The Immigration Act Enforcement Decree specifically includes certain holders of:

• D-7 → E-7 status
• F-2 Resident status

who have resided in Korea for the required period and satisfy the applicable permanent-residency requirements.

Important: Living in Korea for five years does not automatically give someone permanent residency. The applicant must qualify under the applicable F-5 category and meet its additional requirements.

2. Korean Spouse or Family Route

Korean immigration law also provides an F-5 route for certain:

• Spouses of Korean nationals
• Minor children of Korean nationals
• Spouses or minor children of F-5 permanent residents

For one statutory category, a spouse or minor child of a Korean citizen or F-5 holder must have resided in Korea for at least two years, together with the other applicable requirements.

The exact conditions depend on the applicant's circumstances, so marriage alone should never be presented as automatically resulting in permanent residency.

3. Overseas Korean Route

Certain foreign nationals of Korean heritage may progress from F-4 Overseas Korean status to F-5 permanent residence.

The Korea Immigration Service publishes a dedicated settlement guide explaining pathways from F-4 to F-5 and notes requirements involving residence, income and basic behavioral/integration qualifications depending on the route.

4. Professional & Skilled Routes

Permanent-residency categories also exist for certain foreigners with professional qualifications, academic backgrounds or other qualifications specified by immigration regulations. These routes should be checked individually because degree, employment, income, residence and qualification requirements differ by F-5 category.

5. Investment Route

Korea also operates permanent-residency pathways connected with qualifying investment. For example, under the Immigrant Investor Scheme for Public Business, qualifying foreign investors can initially receive F-2 Resident status and may change to F-5 Permanent Resident status after maintaining the qualifying investment for at least five years, subject to the program's requirements. This is a specialized immigration route and should not be confused with the ordinary long-term-residence route.

What Immigration Generally Checks

Depending on the particular F-5 category, immigration authorities may examine several areas.

Good Conduct

Certain permanent-residency routes require the applicant to satisfy good-conduct requirements.

Serious criminal history, immigration violations or other legal issues may therefore affect an application.

Ability to Maintain a Living

Certain categories require evidence that the applicant can maintain a stable livelihood in Korea.

The exact financial standard is not the same for every F-5 category, so applicants should not rely on one universal income figure found online. The applicable requirement should be checked for the applicant's specific F-5 category.

Basic Knowledge & Integration

Certain F-5 categories also require evidence of basic knowledge needed for life in Korean society.

The Korea Immigration & Integration Program (KIIP) can be relevant to this requirement in applicable categories. Some categories have different requirements or exemptions.

Documents You May Need

The exact document list varies by F-5 category. Common categories of evidence can include:

• Passport
• Residence Card
• Application form
• Proof of residence in Korea
• Employment or career documents
• Income or financial documents
• Family relationship documents, when applicable
• Documents proving Korean-language or social-integration requirements, when applicable
• Documents specific to the applicant's F-5 category

Do not prepare an F-5 application using a generic internet checklist alone. Requirements differ considerably between permanent-residency categories.

Confirm the current checklist with Hi Korea or the Immigration Contact Center before applying.

How to Apply

STEP 1 — Identify your F-5 category

Determine which permanent-residency route applies to your current status and circumstances.

STEP 2 — Check current requirements

Confirm residence, income, integration, family, employment or other requirements applicable to that category.

STEP 3 — Prepare supporting documents

Prepare the documents specifically required for your F-5 category.

STEP 4 — Check your immigration office

Confirm the competent immigration office and whether an appointment is required.

STEP 5 — Submit the application

Submit the application and supporting documents according to Korea Immigration Service procedures.

STEP 6 — Immigration review

Immigration authorities review eligibility and supporting evidence. Additional documents may be requested.

STEP 7 — Decision

If approved, the applicant's residence status is changed to Permanent Resident (F-5).

After Receiving F-5

F-5 provides significantly more stable residence in Korea, but it is important to understand that:

F-5 is permanent residency — it is NOT Korean citizenship.

An F-5 holder remains a foreign national unless Korean nationality is separately acquired through the nationality/naturalization process.

There are also rules concerning leaving and returning to Korea. Under the current Immigration Act Enforcement Rule, an F-5 holder seeking to return to Korea within two years after departure falls within the specified re-entry-permit exemption, subject to the legal exceptions.

That is exactly the kind of detail we should include because many foreigners may incorrectly assume that “permanent” means there are no immigration rules after receiving F-5.

Permanent Residency vs. Korean Citizenship

We will explain citizenship and naturalization separately in Guide 2 — Korean Citizenship & Naturalization.

How Foreign Residents Can Become Korean Citizens

Foreign nationals can acquire Republic of Korea nationality through naturalization if they meet the requirements prescribed by Korea's Nationality Act.

Naturalization is different from permanent residency.

• F-5 = You remain a foreign national with permanent residence in Korea.
• Naturalization = You acquire Korean nationality and become a Korean citizen.

Korea broadly provides three naturalization routes:

• General Naturalization
• Simplified Naturalization
• Special Naturalization

1. General Naturalization

This is the standard route for a foreign national who does not qualify for simplified or special naturalization.

Under Korea's Nationality Act, an applicant for general naturalization must satisfy requirements including:

• 5 or more consecutive years of domicile in Korea
• Permanent-residence eligibility/status in Korea
• Being an adult under Korean civil law
• Good conduct and compliance with Korean law
• Ability to support oneself, either through personal assets or abilities or through family with whom the applicant lives
• Basic knowledge required as a Korean citizen, including Korean-language ability and understanding of Korean customs

The Minister of Justice must also determine that granting naturalization would not harm national security, public order or public welfare.

Important for Foreign Residents

Since December 20, 2018, F-5 permanent-resident status is required to apply through the general naturalization route.

So for many ordinary foreign residents, the broad progression is:

Temporary/Long-Term Visa → F-5 Permanent Residency → General Naturalization → Korean Citizenship

But this should not be presented as the route for everyone because simplified and special naturalization have different requirements.

2. Simplified Naturalization

Some foreigners with particular connections to Korea can qualify under less restrictive residence requirements.

For example, the Nationality Act provides a simplified route for certain people who have maintained a domicile in Korea for three consecutive years or more, including qualifying cases involving a parent who was a Korean national or certain Korea-born family circumstances.

There are also separate simplified-naturalization provisions involving marriage to a Korean national.

Because marriage, family history and residence circumstances differ significantly between applicants, these cases should be checked individually with the Korea Immigration Service.

3. Special Naturalization

Special naturalization is available in specific circumstances.

The Nationality Act includes categories such as:

• A person whose father or mother is currently a Korean national
• A person who has made a special contribution to the Republic of Korea
• A person with outstanding ability in fields such as science, economics, culture or sports who is recognized as contributing to Korea's national interest.

This is not an ordinary immigration shortcut.

It is intended for applicants who satisfy the particular statutory criteria.

Korea revised its outstanding-talent special-naturalization criteria again in February 2026, including changes intended to attract highly qualified overseas Korean talent and expand recommendation channels for outstanding professionals.

Korean Language & Understanding of Korea

Naturalization is not based only on the number of years a person has lived in Korea.

For general naturalization, the Nationality Act expressly requires basic qualifications including:

• Korean-language ability
• understanding of Korean customs and society.

This is why KIIP — Korea Immigration & Integration Program becomes important for many foreign residents.

We should explain KIIP separately in this guide rather than telling users that everyone has exactly the same test or requirement.

Naturalization Application — Basic Process

STEP 1 — Determine Your Naturalization Route

First determine whether you fall under:

• General
• Simplified
• Special Naturalization

This is important because the requirements are different.

STEP 2 — Check Eligibility

Confirm your:

• Residence history
• Current immigration status
• Family relationship, if applicable
• Financial/livelihood requirements
• Korean-language and basic-knowledge requirements
• Other requirements applicable to your route.

STEP 3 — Prepare Required Documents

Documents vary according to the naturalization category.

Applicants may need identity, residence, family relationship, livelihood and other supporting documentation.

Foreign-issued documents may also require additional authentication or translation depending on the document and procedure.

STEP 4 — Submit the Naturalization Application

Applications are handled through the Korean immigration/nationality system.

Before visiting, confirm the current procedure and required documents through Hi Korea or 1345.

STEP 5 — Naturalization Review

The Ministry of Justice determines whether the applicant satisfies the applicable requirements under the Nationality Act.

STEP 6 — Approval & Citizenship Procedure

Approved applicants complete the required nationality procedure.

Korea introduced the Pledge of Allegiance and Certificate of Naturalization ceremony in 2018. The Korea Immigration Service explains that naturalized citizens take the national pledge and receive a naturalization certificate as part of the citizenship process.

What About Dual Citizenship?

This part needs particular care.

Do not tell ASK KOREA users that everyone can keep both nationalities.

Korean nationality law has specific rules concerning loss/renunciation of foreign nationality and exceptions.

For example, Korea Immigration Service specifically states that qualifying outstanding talents who acquire nationality through special naturalization can retain their original nationality subject to the applicable pledge and requirements.

Therefore:

• Dual citizenship eligibility depends on the individual case and legal category.
• Applicants should verify their own situation with the Korea Immigration Service before making decisions regarding their existing nationality.

Permanent Residency vs Citizenship

Common Pathways to Long-Term Settlement in Korea

For many foreigners, permanent residency in Korea is the result of a multi-stage immigration pathway rather than a direct change from a student or temporary work visa.

A common pathway may look like:

• Study → Job Seeking → Employment → Residence → Permanent Residence
• D-2 → D-10 → E-series → F-2 → F-5

However, this is an example pathway, not a rule for every foreign resident. Korea has multiple F-2 and F-5 categories, and the correct route depends on education, employment, income, Korean-language ability, length of residence and other qualifications. The Korea Immigration Service itself presents pathways such as “Job Seeker → Professional → Resident → Permanent Resident.”

Route 1 — International Student

D-2 Student

D-2 is used by international students enrolled in eligible higher-education programs in Korea. Graduating from a Korean university does not automatically provide permanent residency. Instead, eligible graduates who want to remain in Korea may move to another appropriate status.

D-2 → D-10 Job Seeker

One important option is D-10 General Job-Seeking status.

The Korea Immigration Service's foreign-resident guide specifically describes international students changing from D-2/D-4 to D-10 after graduation when the applicable requirements are satisfied.

Korean-language ability can be particularly useful. The official guide states that qualifying recent graduates from Korean universities can be exempted from the D-10 points requirement when they meet specified Korean-language conditions, such as TOPIK Level 4 or higher or specified KIIP achievements.

D-10 → Professional Employment

After finding qualifying employment, the foreign resident may change to an appropriate professional employment status, depending on the job and qualifications.

This can include statuses from E-1 Professor through E-7 Specially Designated Activities, depending on the occupation.

Route 2 — Professional Worker

For many foreign professionals, employment in Korea can form part of a longer settlement pathway.

A simplified example is:

Professional Employment → F-2 Residence → F-5 Permanent Residence

But the requirements differ according to the person's employment status and the particular F-2/F-5 category.

Applicants may need to demonstrate factors such as:

• Period of legal residence
• Employment and professional qualifications
• Income or financial stability
• Korean-language/social-integration qualifications
• Good conduct

Not every E-series visa automatically progresses to F-2 or F-5.

Route 3 — F-2 Resident → F-5 Permanent Resident

F-2 Residence is especially important because several Korean immigration pathways use F-2 as an intermediate status before F-5.

The official foreign-resident guide explicitly shows pathways ending:

Professional → Resident → Permanent Resident

and, for certain international entrepreneurs:

D-2/D-4 → D-8/D-9 → F-2 → F-5.

Again, an F-2 visa does not automatically become F-5 after a fixed period in every case.

The specific F-5 category determines the requirements.

Route 4 — Start-up & Business

International students and other eligible foreigners may also have entrepreneurship-related pathways.

The Immigration Service's settlement guide provides a route for qualifying international students progressing through:

• Student / Trainee
• Start-up / International Trade
• Resident
• Permanent Resident

or:

D-2 / D-4 → D-8 / D-9 → F-2 → F-5.

This route has its own business, investment and immigration requirements and should not be confused with ordinary employment immigration.

Route 5 — Special Talent & Science/Technology

Korea also has special settlement pathways for highly qualified foreign talent.

As of 2026, the Ministry of Justice operates Top-Tier and K-STAR pathways for specified high-level talent.

For example, qualifying Top-Tier professionals can receive F-2 residence status and become eligible to apply for F-5 after three years.

The expanded K-STAR track allows qualifying foreign talent recommended by designated universities to receive F-2 after graduation without first obtaining employment and to apply for F-5 after three years. These are special programs with strict eligibility requirements, not general routes for all international students.

Do You Need F-2 Before F-5?

Not always.

This is an important point.

Korea has numerous F-5 categories, and some applicants can qualify under routes that do not follow the simple:

E-7 → F-2 → F-5

sequence.

Therefore, foreigners should first identify the specific F-5 category for which they may qualify rather than changing visas simply because they believe F-2 is always mandatory.

A Simple Way to Think About It

These are pathway examples, not guarantees of eligibility.

Before Planning Your Route

Do not choose a visa simply because someone online followed that route.

Before changing status, check:

• What visa do I currently hold?
• How long have I legally lived in Korea?
• Does my education qualify?
• Does my employment qualify?
• Do I meet the applicable income requirement?
• Do I need TOPIK or KIIP?
• Which F-5 category am I ultimately targeting?

This last question is particularly important.

Instead of asking only:

“How do I get F-5?”

a foreign resident should ask:

“Which F-5 category can I qualify for, and what status should I maintain before applying?”

Residency, Permanent Residence and Integration in Korea

Foreign nationals who are married to Korean citizens or have qualifying family relationships may have different residence and permanent-residency pathways from ordinary workers or international students.

The Korea Immigration & Integration Program (KIIP) is also important for many foreign residents preparing for long-term settlement, permanent residence or naturalization.

Marriage to a Korean Citizen

A foreign national legally married to a Korean citizen may qualify for F-6 Marriage Migrant status, subject to immigration requirements.

Marriage itself does not automatically provide:

• F-5 Permanent Residency
• Korean Citizenship

These require separate applications and their own eligibility requirements.

For naturalization, Korea's Nationality Act provides a simplified route for qualifying spouses of Korean nationals. One statutory route applies where the applicant has maintained a domicile in Korea for at least two consecutive years while married to the Korean spouse. Another applies after three years have passed since marriage with at least one consecutive year of domicile in Korea while married, subject to the other requirements.

Children & Other Family Situations

Different immigration and nationality rules may apply when the applicant:

• Has a Korean-national child
• Is a minor child of a Korean national
• Is the spouse or minor child of an F-5 permanent resident
• Experiences divorce or the death/disappearance of a Korean spouse

Because these cases depend heavily on the individual family situation, ASK KOREA should direct users to 1345 or the competent immigration office rather than present one rule as applying to everyone.

KIIP — Korea Immigration & Integration Program

KIIP (사회통합프로그램) is operated for immigrants who want to acquire Korean-language skills and an understanding of Korean society needed for settlement.

The program includes:

• Korean Language and Culture
• Understanding Korean Society

Completion or specified KIIP results can be relevant to certain immigration and naturalization requirements or evaluations. The exact benefit depends on the immigration procedure involved.

Applications and KIIP information are handled through Socinet.

Documents, Application and What to Do After F-5 or Korean Citizenship

This final guide brings together the practical steps foreigners should know when preparing an F-5 permanent-residence or naturalization application, and what happens after approval.

The exact requirements depend on the applicant's immigration or naturalization category, so there is no single document checklist that applies to everyone.

Documents You May Need

Depending on the application, commonly required categories of documents can include:

• Passport
• Residence Card
• Application form
• Proof of residence
• Employment or career documents
• Income and financial documents
• Family or marriage documents, when applicable
• Korean-language or KIIP-related documents, when applicable
• Documents proving the requirements of the specific F-5 or naturalization category

Foreign-issued documents may require translation and/or authentication depending on the document and procedure.

Do not prepare an application using a generic online checklist alone. Confirm the current checklist for your exact category before submitting.

Before You Apply

1 — Identify your exact category

Do not apply simply for “F-5” or “citizenship” without first determining the applicable route.

2 — Check the latest requirements

Requirements can change. Check Hi Korea or contact 1345.

3 — Prepare supporting documents

Make sure names, dates and personal information are consistent across documents.

4 — Confirm where and how to apply

Check the competent immigration office and whether an appointment or other procedure is required.

5 — Keep copies

Keep copies of the application and important supporting documents.

After Receiving F-5

F-5 gives the holder permanent-resident status, but the person remains a foreign national.

After approval, keep your residence information current and follow immigration requirements concerning matters such as address changes and international travel.

After Naturalization

Naturalization is different because the applicant acquires Korean nationality after completing the legally required procedure.

After nationality acquisition, additional administrative steps can be necessary, including matters connected with:

• Nationality records
• Resident registration
• Identification documents
• Korean passport application
• Existing foreign nationality, where applicable

Rules concerning retention or renunciation of another nationality depend on the person's legal circumstances. Do not assume dual nationality is automatically permitted.

Five Mistakes to Avoid

• “I lived in Korea for five years, so F-5 is automatic.” → No. Residence period alone does not guarantee F-5.
• “I married a Korean, so I automatically get citizenship.” → No. A separate naturalization process is required.
• “F-5 means I am a Korean citizen.” → No. An F-5 holder remains a foreign national.
• “Everyone needs exactly the same F-5 documents.” → No. Requirements differ by category.
• “Everyone can keep dual nationality after naturalization.” → No. Nationality rules depend on the applicant's circumstances and applicable legal category.

For individual cases, contact 1345 before submitting an application because the required documents and procedures depend on the applicant's status.
