D-8, D-8-4 or F-5: choosing the right Korean investor visa

Foreign founders often arrive asking for ‘the investor visa’, as if there were one. Korea’s immigration system is more layered than that. Every foreigner in Korea stays under a status of sojourn (체류자격, cheryu jagyeok) granted under Article 10 of the Immigration Act, and the long-term statuses, each with its own letter-and-number code, are defined in the annexed tables to Article 12 of the Enforcement Decree. Several of them are meant for people who bring money or a business to Korea; one of them, at the top, is permanent.

This guide maps the statuses a business founder is likely to meet, explains who each is for and how they connect, and ends with a quiz that points you to your starting rung. The detail of each status is set by the Enforcement Decree and by the Ministry of Justice’s operational manuals, which change more often than the Act — so treat the figures here as a map, not a substitute for checking the current rules for your case.

The D-8 family: corporate investment

The D-8 status — corporate investment (기업투자, gieop tuja) — is defined in the Enforcement Decree as covering foreigners who manage or work in a Korean enterprise in which they have invested under the Foreign Investment Promotion Act, together with certain venture and technology founders. It is divided into sub-types, each with its own test.

D-8-1: the corporate investor

The standard route, and the one most readers of this site will take. Under Article 2 of the Foreign Investment Promotion Act and Article 2 of its Enforcement Decree, a foreigner’s investment counts as foreign investment when it is at least KRW 100 million and gives the investor at least 10% of the voting shares. The investment is notified under Article 5, the money is wired from abroad, and the company is registered as a foreign-invested company (외국인투자기업) under Article 21.

The investor then applies for D-8-1, either at a Korean consulate abroad or as a change of status inside Korea under Article 24 of the Immigration Act. Immigration expects independent business premises and an applicant who actually runs the company. Grants run for up to five years and are extended under Article 25 while the company trades. The full checklist is in our D-8 requirements guide.

D-8-4: the start-up visa

D-8-4 — technology start-up (기술창업, gisul changeop) — was designed for a different founder: someone with ideas and qualifications rather than capital. Instead of a large investment, the test is built on three elements.

The first is education: typically a bachelor’s degree or higher, from Korea or abroad. The second is technology: the founder holds, or has applied for, intellectual property (지식재산권) such as a patent, utility model or design right, or has comparable technology. The third is points: the founder accumulates points in OASIS (Overall Assistance for Start-up Immigration System), a government programme of start-up education, mentoring, competitions and IP support, and must reach the required score. The founder sets up a Korean corporation, usually a Jusik Hoesa, and runs it.

For founders still in the preparation phase, there is a related job-seeking status for technology start-up preparation, D-10-2, which can bridge the time needed to collect OASIS points and file IP before switching to D-8-4.

D-8-1 is bought with capital. D-8-4 is earned with qualifications.

D-8-2 and D-8-3: the less common routes

D-8-2 is for founders of companies certified as venture businesses under Korea’s venture business law. Certification is a separate process with its own criteria — technology, R&D investment or venture capital backing — so in practice D-8-2 is a route for companies that already have Korean institutional support.

D-8-3 applies the investment logic of D-8-1 to an individual business rather than a corporation: the foreign investor puts KRW 100 million or more into a sole proprietorship he or she runs. It is simpler to set up but leaves the owner personally liable and is less familiar to banks and partners. For most founders, D-8-1 with a Jusik Hoesa is the better vehicle.

Look-alikes: D-7 and D-9

Two other statuses are often mistaken for investor visas. Intra-company transfer (주재, D-7) is for employees sent by a foreign company to its Korean branch or liaison office — there is no Korean company being invested in, so D-8 does not fit. Trade management (무역경영, D-9) covers foreigners engaged in trade or in running certain businesses in Korea, including some who have not made a qualifying foreign investment.

Neither is wrong; each fits a particular structure. A group that registers a branch (외국회사 지점) under Article 614 of the Commercial Act sends its manager on D-7. A founder who forms a Jusik Hoesa with KRW 100 million from abroad applies for D-8-1.

F-5: permanent residence

At the top of the ladder is permanent residence (영주, F-5), recognised as a separate category in Article 10-3 of the Immigration Act. An F-5 holder may live in Korea without a time limit, work without restriction and is no longer tied to the company or employer that brought him or her.

The Enforcement Decree lists many routes to F-5. Two matter most to investors. The first is a direct investor route: a foreigner who has invested at least USD 500,000 under the Foreign Investment Promotion Act and employs at least five Korean nationals may qualify for permanent residence. The second is time: foreigners who have lived in Korea lawfully for a qualifying period on certain statuses, with sufficient income, assets and basic knowledge of Korean society, may apply on residence-based routes.

Korea also runs investment immigration schemes outside the company route — investment in designated real estate or in public-interest funds — which lead to residence and, after a period, to permanent residence. They are aimed at passive investors rather than founders and have their own thresholds, which have been revised several times.

What each status lets you do

A status of sojourn is not only permission to stay; it defines what you may do. A D-8-1 holder may manage and work for the company he or she invested in. A D-8-4 holder runs the start-up. A D-7 holder works for the branch or liaison office of the employer that sent him. Activities outside those boundaries — a second job, paid work for another company, a different business — need permission for activities outside the status (체류자격 외 활동허가) under Article 20 of the Immigration Act, or a different status altogether.

Permanent residence removes these limits. That is often the real reason founders aim for F-5: not the length of stay, which a renewed D-8 already provides, but the freedom to change businesses, take board seats or work for others without asking first.

Indicative. Every case is assessed on its own file.

Moving between rungs

Statuses are not locked boxes. Under Article 24 of the Immigration Act, a foreigner in Korea may apply to change from one status to another when the conditions of the new one are met, and many founders climb the ladder this way without leaving the country.

Some transitions are routine: a graduate on a student status moving to start-up preparation and then to D-8-4; a D-8-4 founder whose company raises KRW 100 million of foreign investment moving to D-8-1; a D-7 manager whose employer converts its branch into a foreign-invested subsidiary moving to D-8-1. Others are not permitted from inside Korea, particularly from short-term visitor statuses, and require an application at a consulate abroad.

The practical rule is to apply for the new status before the current one expires, with a complete file. A pending application generally allows the applicant to remain while it is decided; an expired status does not.

How immigration actually decides

The Act and the Enforcement Decree set the categories and the minimum conditions; the detail lives in the Ministry of Justice’s operational manuals, which officers apply. Within those rules officers have discretion, and it shows in three places.

The first is credibility: does the business plan match the capital, the premises and the applicant’s background? The second is documentation: are the names, amounts and dates consistent across the foreign investment certificate, the bank certificate and the registry? The third is history: has the applicant complied with previous statuses, extended on time and kept the company active? Applicants who score well on all three rarely see their application questioned; applicants who stumble on one are asked for more.

Family across the ladder

On D-8, D-7 and D-9, a holder’s spouse and minor children can usually join on dependant status (동반, F-3), which runs with the main holder’s stay but does not by itself allow work. Permanent residence changes that: family members may qualify for residence of their own, and an F-5 holder’s spouse can access broader rights. If a working spouse matters, map the family’s statuses as carefully as your own.

Tax follows residence, not the visa

Moving to Korea on any of these statuses can make you a Korean tax resident. Under Article 1-2 of the Income Tax Act, an individual with a domicile in Korea, or who has resided in Korea for 183 days or more, is a resident. Residents are generally taxed on worldwide income.

There is a significant concession for newcomers. Under Article 3 of the Income Tax Act, a foreign resident who has had a domicile or residence in Korea for no more than five years in total over the previous ten years is taxed on foreign-source income only to the extent it is paid in or remitted to Korea. For a founder in the first years, that can make a large difference — and makes it worth planning which income stays outside Korea.

All the rungs, side by side

Simplified comparison. Conditions are set by the Enforcement Decree and Ministry of Justice guidance and change from time to time.

Three founders, three starting rungs

The brand owner with capital

A cosmetics brand owner from Poland wants to run Korean distribution from Seoul. She forms a Jusik Hoesa with KRW 200 million wired from her own account, registers it as a foreign-invested company and applies for D-8-1. If the company grows and she hires five Koreans, a larger investment later opens F-5.

The graduate engineer

A robotics engineer finishing a master’s degree in Daejeon has a patent application and a prototype but little capital. He takes the OASIS programme, files his IP, and moves from his student status to the start-up preparation status and then to D-8-4 once his corporation is formed.

The group manager

A Dutch company opens a branch in Busan to service its shipyard customers and sends its regional manager. He goes on D-7. If the group later converts the branch into a subsidiary with KRW 100 million or more of foreign investment, D-8-1 becomes available.

Planning for the top rung from day one

• Capital. If F-5 through investment is the goal, the company will need USD 500,000 of foreign investment eventually. Adding it later is possible, but each increase is another notification and registration tax.
• Hiring. Korean employees on payroll count; contractors do not. Keep payroll and social insurance records clean from the first hire.
• Continuity. Gaps in status, long absences and late extensions can interrupt residence-based routes.
• Records. Keep every remittance certificate, foreign investment registration and annual accounts. An F-5 application years later will ask for the history.

Where you apply and who decides

Visa applications from abroad go to the Korean embassy or consulate responsible for your country of residence; they forward complex cases, including many first D-8 applications, to the Ministry of Justice in Korea. Applications inside Korea — changes of status, extensions, permission for outside activities and, eventually, permanent residence — go to the immigration office (출입국·외국인청) with jurisdiction over your address, usually by appointment booked through the government’s HiKorea portal.

Decisions are made by the Ministry of Justice and its immigration offices, not by Invest KOREA, the bank or your agent. What those three can do is make the file complete and consistent before it reaches the officer — which, in practice, is what decides how long the officer spends on it.

Mistakes we see

1. Choosing D-8-3 to save effort. It works, but a sole proprietorship leaves the investor personally liable and is harder to grow into F-5.
2. Expecting D-8-4 without OASIS. The points are part of the test, not a formality.
3. Using D-8 for a branch manager. No Korean company, no D-8; the manager needs D-7.
4. Counting contractors as employees for the F-5 hiring threshold.
5. Letting the status lapse while waiting for a better one. Always extend the current status on time.
