Which Visa Lets You Work Freely in Korea? F-4, F-5, and F-6 Explained (2026)

F-4, F-5, and F-6 visa holders can work in Korea without employer sponsorship. No work permit, no company filing, no immigration approval needed each time you change jobs. But the rules on what jobs you can take differ significantly between these three statuses.

This guide explains who qualifies for each status, what work F-4 holders cannot do and why that restriction matters more than most people realize, how to convert from F-4 to F-5, how F-6 protections work after divorce, and how to check any specific situation before acting.

F-4: the overseas Korean visa

Who qualifies

The legal basis is the Act on the Immigration and Legal Status of Overseas Koreans (재외동포법, jaeoe dongpobeop), Article 2.

Two eligibility categories:

Category A. A current ROK national residing abroad who has permanent residence rights abroad or intent to settle outside Korea.

Category B. A person who formerly held ROK nationality and later acquired foreign citizenship, or a lineal descendant of such a person who holds foreign citizenship. This includes emigrants who left before 1948, when the Republic of Korea was formally established, as well as later emigrants.

Lineage extends to grandchildren. Great-grandchildren are not covered under standard F-4 eligibility.

Military service restriction. Male applicants who acquired foreign citizenship and lost ROK nationality after May 1, 2018, without completing mandatory military service or receiving a legal exemption, cannot hold F-4 status until December 31 of the year they turn 40. This is an eligibility bar, not a procedural delay.

The February 12, 2026 change. Before this date, ethnic Koreans from China and former Soviet states were generally directed to the H-2 (방문취업, bangmun chwiyeop) visa rather than F-4. The country-of-origin distinction has been eliminated: ethnic Koreans from any country can now qualify for F-4. About 860,000 overseas Koreans currently live in Korea across all visa statuses (F-4, F-5, H-2, and others). New H-2 issuance was suspended on February 12, 2026. Existing H-2 holders retain their status until expiry and may convert voluntarily.

Visa mechanics

F-4 is a multiple-entry visa with a standard 3-year period of stay. You can travel abroad and return without a separate re-entry permit as long as your stay period has not expired.

After arrival, you must register your Resident Card (거소증, geosocheung) within 90 days at a local immigration office or immigration service center. Verify the current official document name and procedure at HiKorea (hikorea.go.kr) before applying, as terminology varies across sources.

The work restriction: what F-4 holders cannot do

F-4 is not a free pass for all employment. Every F-4 applicant must sign a Non-Employment Pledge (국내 단순노무행위 불취업 서약서, bulchwiyeop seoyakseo) at the time of application. This is legally binding.

The governing document is Ministry of Justice Notice 2026-35 (법무부고시 제2026-35호, beopmubugosi), effective February 12, 2026. It defines which simple-labor (단순노무, dansun nomu) occupations are prohibited.

What is newly permitted from February 12, 2026 (these 10 occupations were added under Notice 2026-35):

What was already permitted before 2026 (under Notice 2023-187, effective May 1, 2023):

If you currently work as a kitchen assistant or in fast food preparation, this was legal since May 2023. It is not a 2026 change.

What remains restricted under Notice 2026-35:

Morality-based restricted occupations include karaoke service workers (노래방 종사원), PC room workers, liquor service workers (유흥주점 종사자), workers at adult entertainment or gambling venues, golf caddies, bathhouse attendants, and street vendors (노점 판매원).

A note on building security guards. Standard F-4 holders cannot work as building security guards (건물 경비원). This applies to both apartment security guards and commercial building security guards. The exception is F-4-R holders in government-designated depopulation zones, who may have expanded permissions within those zones. If you are considering any security guard role, confirm your status and location with HiKorea or call 1345 before accepting the position.

The restriction that bites at the worst moment

Immigration offices do not typically audit daily employment during the F-4 period. The restriction becomes serious at two points: when you apply for F-5 permanent residency, and when you renew your visa.

When you apply for F-5, immigration reviews your income documentation and cross-checks your employment history. F-4 holders who worked restricted jobs and then applied for F-5 have had their applications denied. You lose permanent residency, not just a warning.

This is the primary enforcement mechanism. Treat the Non-Employment Pledge as a document with real consequences, not a procedural formality.

Self-employment and business registration

F-4 holders can register as sole proprietors (개인사업자) at the district tax office (세무서). Bring your Resident Card, address documentation, and a completed application form.

You can also found or serve as a director of a company registered in Korea. There is no legal restriction on F-4 holders as business owners.

The relevant distinction: working as an employee in a restricted role is prohibited. Operating a business that engages in that activity as the owner is a different legal situation. However, borderline cases exist. Call 1345 before registering any business in an industry adjacent to restricted occupations.

Freelance work in professional fields such as writing, design, IT, translation, consulting, and tutoring is not restricted.

Tax and health insurance

Korean tax residency rules apply to F-4 holders the same way they apply to other long-term residents. The 183-day rule applies for determining Korean tax residence. Foreign nationals resident in Korea for fewer than 5 cumulative years in the preceding 10 years are taxed on Korean-source income and on foreign-source income only if remitted to Korea. See PwC Korea Tax Summaries for the current individual residence rules.

National Health Insurance (국민건강보험, gunmin geongang boheom) enrollment is mandatory after 6 months of continuous residence. Verify the current enrollment rules and any recent updates at nhis.or.kr or by calling 1345.

F-5: permanent residency

Work rights

F-5 (영주권, yeongjugwon) holders have no restrictions on employment activities. Any occupation, any industry, any type of work. The only applicable requirements are professional licenses that apply equally to all workers in Korea regardless of visa status (medical, legal, architectural licensing, and similar).

How to convert from F-4 to F-5

The main route for overseas Koreans is the F-5-6 sub-type. Five requirements apply:

1. Continuous residence. 2 or more years of continuous F-4 residence in Korea.

2. Income. One of the following must be met:

• Annual income at or above Korea's per capita GNI for the current year. This figure updates annually. Check the current year's figure at kostat.go.kr before applying.
• If combining income with a cohabiting family member, your share must be at least 50% of per capita GNI.
• Age 60 or older: qualifying pension income may substitute.
• Net worth above the qualifying threshold (excluding debt), based on average household net worth. This figure also updates annually. Confirm at kostat.go.kr.
• Annual business revenue of 2 billion KRW or more, or a qualifying investment.

3. Language. Standard requirement: KIIP (사회통합프로그램, sahoe tonghap peulogeulaem) Level 5 completion, or passing the permanent residence qualification exam with 60 or more points. Exemptions apply if you held F-4 status for 3 or more years, are age 60 or older, completed Korean elementary school or higher, are age 13 or younger, or previously held Korean citizenship. Verify any changes to language requirements introduced under the February 2026 reform at HiKorea.

4. Criminal record. Clean record in Korea and abroad. Foreign criminal certificates may be waived if you have not left Korea for more than 6 consecutive months.

5. No outstanding violations. No immigration law violations, no unpaid national taxes, no unpaid health insurance premiums.

Processing time is approximately 2 to 3 months.

When converting to F-5 is worth it

Convert if: you want to work in any occupation without restrictions, you want local voting rights after 3 years of F-5 status, you want indefinite residence without renewal pressure, or your spouse or minor children would benefit from F-2 residence status.

Stay on F-4 if: your work is in professional or white-collar fields where the simple-labor restriction never applies, you do not yet meet the income threshold, or you may leave Korea within a few years.

Voting rights

F-5 holders with 3 or more years of continuous F-5 status may vote in local elections only. They cannot vote in presidential or National Assembly elections. Some long-term F-2, F-4, and F-6 holders may also qualify under National Election Commission rules; check nec.go.kr for current eligibility criteria in advance of election periods.

F-6: marriage migration visa

Who qualifies and the three sub-types

F-6 (결혼이민, gyeolhon imin) is for foreign nationals married to Korean citizens. There are three sub-types with different qualifying bases:

F-6-1. Valid, ongoing marriage to a Korean citizen. The holder is residing in Korea to continue the marriage.

F-6-2. The marriage has ended, but the foreign spouse is raising a minor child born from the marriage with the Korean citizen.

F-6-3. The marriage ended due to circumstances not primarily the foreign spouse's fault: the Korean spouse has died, has been declared missing by a Korean court, or was found mainly responsible for the marriage breakdown in a judicial divorce.

Work rights are fully unrestricted across all three sub-types. F-6 holders can work in any occupation without restrictions, the same as F-5 holders.

Validity is up to 3 years per grant, renewable while the qualifying status continues.

If your marriage ends: what actually happens to your visa

This is where F-6 rules are most often misunderstood.

During separation or pending divorce proceedings. F-6-1 status can be extended while you are separated or while a divorce lawsuit is pending in court. You do not automatically lose status when separation begins.

After divorce: the general rule. If the divorce is finalized and no alternative basis applies, an F-6-1 holder would need to change status or leave Korea.

Exception 1: F-6-2 (child custody). If you have custody of or are raising a minor child born from the marriage with your Korean spouse, you qualify for F-6-2 status. Your work authorization continues.

Exception 2: F-6-3 (judicial divorce, Korean spouse mainly at fault). If a Korean court issues a judicial divorce (재판이혼, jaeban ihon) and finds your Korean spouse mainly responsible for the marriage breakdown, you qualify for F-6-3. The Korean Supreme Court has confirmed the standard is "mainly responsible," not "solely responsible." Causes include domestic violence, abandonment, and systematic abuse.

This exception requires a judicial divorce. An agreed mutual divorce (협의이혼, hyeobui ihon) does not qualify.

Exception 3: F-6-3 (Korean spouse death or disappearance). If your Korean spouse dies or is declared missing by a Korean court, you qualify for F-6-3.

If you are facing any of these situations, call the immigration contact center at 1345 before making decisions. The specific documentation requirements and timing matter.

Converting from F-6 to F-5

The F-5-2 route applies. Requirements:

1. 2 or more years of continuous F-6 residence in Korea.
2. KIIP Level 5 completion. As of April 2019, TOPIK Level 4 is no longer accepted. Only KIIP Level 5 qualifies.
3. One of: KRW 30 million or more in liquid assets, or proof of steady employment income.
4. Clean Korean criminal background check.
5. Valid marriage at application time, or divorced with a qualifying basis.

Can I do this job? Specific answers

These are the most common questions from F-4 holders. F-5 and F-6 answers are the same for all: yes, no occupation restrictions.

Serving as a kitchen employee in a regular restaurant is different from working as a liquor service worker at a nightclub. If you are unsure which category applies to a specific position, describe the exact role when you call 1345.

Common misconceptions

"F-4 means I have all the same rights as a Korean citizen." No. F-4 holders cannot vote in any Korean election. They cannot hold standard civil service positions. They do not hold a Korean passport. The simple-labor restriction applies. They must separately enroll in health insurance and pay Korean taxes.

"F-4 holders can do any job." No. The simple-labor restriction covers 37+ specific occupations and is legally binding. Notice 2026-35 expanded the permitted list significantly, but delivery, cleaning, waste collection, security guarding, and all morality-based categories remain restricted.

"If I work a restricted job, the risk is only getting caught on the job." No. The primary enforcement point is the F-5 permanent residency application, which can be months or years later. Immigration cross-references income documentation at that point. The cost is not a fine. The cost is losing eligibility for permanent residency.

"Kitchen work and fast food jobs are new F-4 permissions from 2026." No. These have been permitted since May 1, 2023 under Notice 2023-187. They were not introduced by the February 2026 changes.

"F-4 holders can now work as building security guards after the 2026 reform." No, for standard F-4. Building security guards remain restricted under Notice 2026-35 for standard F-4 holders. Only F-4-R holders in designated depopulation zones may be eligible, within those zones.

"My non-Korean spouse also has F-4 rights because I'm on F-4." No. F-4 is not transferable. A non-Korean spouse of an F-4 holder would typically hold F-3 (dependent) status, which does not include work rights. In-country F-3 applications were suspended in April 2025. Apply through the Korean consulate in your home country. Verify current status at HiKorea.

"Divorcing my Korean spouse means I automatically have to leave Korea." Not necessarily. Three specific circumstances allow continued residence after divorce: F-6-2 (child custody), F-6-3 (Korean spouse mainly at fault in a judicial divorce), and F-6-3 (Korean spouse died or was declared missing).

"The 2026 integration means 860,000 H-2 holders converted to F-4." No. About 860,000 overseas Koreans are currently in Korea across all visa types, not 860,000 former H-2 holders. Actual H-2 holders at the time of integration numbered approximately 84,000 to 93,000. New H-2 issuance was suspended; existing holders retain their status.

"F-5 holders vote just like Korean citizens." Partially. F-5 holders can vote in local elections only, after 3 or more years of continuous F-5 status. They cannot vote in presidential or National Assembly elections.

FAQ

Do F-4, F-5, and F-6 holders need an employer to sponsor their work visa? No. F-series visa holders do not need employer sponsorship to work. The visa itself is the work authorization. You can change jobs, freelance, or start a business without immigration approval. This is the main practical difference from work visas like E-7.

What jobs can F-4 holders NOT do in Korea? F-4 holders cannot work as delivery riders, cleaners, waste collectors, apartment security guards, building security guards (in standard F-4 status), flyer distributors, street vendors, or in adult entertainment or gambling establishments. These remain restricted under MoJ Notice 2026-35 as of February 2026. The full list covers 37 simple-labor categories and 8 morality-based categories.

Can F-4 holders work in construction or a warehouse? Yes, from February 12, 2026. Construction simple laborers (건설 단순 종사원) and loading and unloading workers (하역 및 적재 단순종사원) are among 10 occupations newly permitted under MoJ Notice 2026-35.

Can F-4 holders work in a restaurant kitchen? Yes. Kitchen assistants (주방 보조원) and fast food preparation workers (패스트푸드 준비원) have been permitted since May 1, 2023 under MoJ Notice 2023-187. This was not a change introduced in 2026.

What happens if an F-4 holder works a restricted job? The primary documented consequence is denial of F-5 permanent residency. Immigration cross-checks income records and employment history when you apply for F-5. Visa extension refusal and, in serious cases, visa cancellation are also possible.

How do F-4 holders convert to F-5 permanent residency? The main route (F-5-6) requires 2 or more years of continuous F-4 residence in Korea, income at or above Korea's per capita GNI for the current year (check kostat.go.kr), KIIP Level 5 completion or an approved exemption, and a clean criminal record with no outstanding tax or insurance payments. Processing takes approximately 2 to 3 months.

Does divorce cancel an F-6 visa? Not automatically. F-6 holders can remain in Korea after divorce in three situations: if they have custody of a minor child from the marriage (F-6-2 basis), if a Korean court finds the Korean spouse mainly responsible for the marriage breakdown in a judicial divorce (F-6-3 basis), or if the Korean spouse has died or been declared missing (F-6-3 basis). An agreed mutual divorce does not qualify for the fault-based exception.

Can F-5 holders vote in Korean elections? F-5 holders who have held continuous F-5 status for 3 or more years can vote in local elections only. They cannot vote in presidential or National Assembly elections. Confirm eligibility with the National Election Commission before election periods.

Do F-4 holders need to register and pay into health insurance? Yes. F-4 holders must register for a Resident Card (거소증, geosocheung) within 90 days of arrival. Enrollment in National Health Insurance (국민건강보험) is mandatory after 6 months of continuous residence. Verify current enrollment rules at nhis.or.kr or by calling 1345.

Can an F-4 holder start a business or freelance? Yes. F-4 holders can register as sole proprietors (개인사업자) at the district tax office. They can also found or direct a company. Freelance work in professional fields (writing, design, IT, consulting, tutoring) is not restricted. The business activity itself must not constitute a restricted simple-labor occupation.
