The visa (재외동포, Overseas Korean) is one of Korea's most flexible long-term visas. It allows ethnic Koreans with foreign citizenship to live, work, and move freely in Korea without the restrictions that apply to most work visas. The F-4 is renewable every 2 years with no fixed expiry, and after 5 years of continuous stay, holders can apply for permanent residency.

F-4 eligibility is defined by the Act on the Immigration and Legal Status of Overseas Koreans (재외동포의 출입국과 법적 지위에 관한 법률). There are two main categories:
Category 1 — Former Korean nationals: Persons who once held Korean citizenship and voluntarily acquired foreign citizenship (귀화 또는 국적변경). This includes people who emigrated to the US, Canada, Australia, or other countries and naturalised there.
Category 2 — Direct descendants: Persons who were born to a parent or grandparent who held Korean nationality at the time of their birth. This captures the children and grandchildren of Koreans who emigrated before acquiring foreign citizenship (for example, ethnic Koreans born in China or the former Soviet Union).
Note: F-4 is specifically for ethnic Koreans with foreign citizenship. Korean nationals (dual citizens who have already registered their Korean identity) are not issued F-4 — they enter on their Korean passport.
For ethnic Koreans from China (조선족) and the 21 post-Soviet/CIS countries (고려인), the F-4 application process is more restrictive. KIS uses the F-4 for this group as a pathway away from unskilled labour, so eligibility requires demonstrating that you are unlikely to do simple manual work. You must generally meet one or more of the following:
For these applicants, the Chinese or CIS-issued documents confirming Korean ethnicity (호구부 — household registration — and birth certificate) must be original and translated into Korean. KIS requires notarisation or official confirmation through the relevant embassy.
allows broad employment freedom in Korea — holders can work in almost any field without a separate work permit. However, there is one absolute restriction: 단순노무 (simple/unskilled labour) is prohibited in ALL industries.
This means holders cannot legally work as: factory floor workers, construction day labourers, restaurant kitchen helpers (dish washers, delivery riders in unskilled roles), cleaning staff, and similar roles that are categorised as unskilled under the Korean Standard Occupational Classification.
When applying for , applicants must sign a non-employment pledge (비취업 서약서) specifically for the restricted occupations listed in Ministry of Justice Notice 2023-187. Violations result in visa cancellation.
Outside of simple labour, holders can: be employed as white-collar professionals, run businesses, invest, freelance, and engage in the vast majority of legal economic activities.
An visa is typically issued as a 2-year multiple-entry visa. After arriving, register your foreign residency (국내거소신고) at the local immigration office within 90 days. Once registered:
From abroad (applying at a Korean embassy or consulate):
From inside Korea (change of status or re-application):
Key documents:
After holding status for 5 consecutive years in Korea, you can apply for (영주, permanent residency) under the overseas Korean pathway. Requirements:
grants indefinite right of residence. Unlike , it does not require periodic renewal — once granted, it is permanent unless voluntarily surrendered or revoked for serious violations.
Start gathering your Korean ancestry documents (가족관계증명서 or overseas nationality documents) well in advance — for China and CIS applicants, the official translation and notarisation process can take weeks.
If you are from a CIS country, verify that your ethnic Korean identity documents show the word 고려인 or Korean as your ethnicity (민족). Chinese 조선족 applicants should have 朝鮮族 on their 호구부.
Even though F-4 allows broad employment, keep a copy of the restricted occupation pledge you signed. If your employer asks you to do work in restricted categories, politely decline and document it.
Register your domestic residency (국내거소신고) — not 외국인 등록 — within 90 days of arrival. F-4 holders use the domestic residency card (국내거소신고증), not the alien registration card (외국인등록증).
Track your days in Korea carefully for the F-5 5-year requirement. Long absences (over 30 days) can break the continuous stay calculation under some F-5 pathways.

Visa Process
Alien Registration Card (ARC)
The Alien Registration Card (ARC) is the official ID card issued to foreigners staying in South Korea for 91 days or longer. It is required to open a bank account, sign a phone contract, and access most public services.

HiKorea
How to use HiKorea (www.hikorea.go.kr) — Korea's official immigration portal for visa extensions, status changes, and ARC renewal. Processing time: 3-10 business days.
Visa Process
Visa Extension (Stay Period Extension)
A visa extension — officially called a 'stay period extension' (체류기간 연장) in Korean immigration law — allows a foreigner to legally remain in Korea beyond the expiry date on their current visa or ARC without leaving the country.
Visa Process
Status of Sojourn Change (체류자격 변경)
A status of sojourn change allows a foreigner already in South Korea to switch from one visa category to another without leaving the country — for example, from a D-2 student visa to an E-7 skilled worker visa upon graduation and employment.
I was born in the US to Korean-American parents — do I qualify for F-4?
Yes, if one of your parents held Korean citizenship at the time of your birth (even if they later naturalised as a US citizen), you are an ethnic Korean descendant and qualify for F-4. You will need documents such as your parent's old Korean passport, Korean family register, or naturalisation records showing they were previously Korean nationals. If both your parents were already naturalised Americans before you were born, you may or may not qualify — consult your local Korean consulate.
Can I work full-time at a Korean company on F-4?
Yes. F-4 holders can be employed at any Korean company in professional or semi-professional roles without a separate work permit. You simply sign an employment contract and report to work. The only restriction is simple/unskilled labour — any professional, technical, managerial, or creative role is permitted.
Can a 조선족 (Korean-Chinese) with no university degree get F-4?
For Chinese (조선족) applicants without a degree, there are other qualifying categories: holding a designated Korean national technical qualification certificate, being a corporate representative, being aged 60 or older, having completed KIIP Stage 4+, or having graduated from a Korean high school or university. If none of these apply, you may need to first obtain a qualification or pursue another pathway.
Does F-4 allow me to open a business in Korea?
Yes. F-4 holders can register businesses (사업자등록), operate as sole proprietors or corporate representatives, and engage in commercial activities freely, subject to the same rules Korean citizens follow. There are no special investment thresholds required to run a normal business under F-4.
What is the difference between F-4 and H-2?
Both are for ethnic Koreans (overseas Koreans), but they are different in scope. (방문취업, working visit) is designed specifically for Chinese and CIS ethnic Koreans aged 25+ for unskilled and semi-skilled work in designated industries (manufacturing, construction, agriculture, etc.). H-2 holders are limited to specific industries. , in contrast, allows work in almost any professional role except simple labour. F-4 requires meeting stricter eligibility criteria (degree, qualification, etc. for China/CIS applicants), while H-2 has a separate quota system.
