How to Start a Business in Korea as a Foreigner — The 2026 Guide

For foreign nationals looking to do business in Korea, the first visa category they usually encounter is the D-8 visa. Overseas immigration consultancies, the Korean government's English-language materials, and most press coverage all introduce D-8 as Korea's "business visa." As a result, many applicants assume that a D-8 is required to start any business in Korea.

In practice, however, D-8 is designed for foreign nationals who establish a corporation or invest in an existing one. Its subcategories make this clear: D-8-1 for essential specialists (such as executives) of a foreign-invested corporation, D-8-2 for founders of venture companies, D-8-3 for joint venture partners with a Korean national, and D-8-4 for technology-based startup founders. All of them presuppose a corporation or investment-backed enterprise. The applicant sets up or joins a corporate entity and resides in Korea as its representative or officer.

But most people considering Business Immigration are not planning a corporate-level venture or a tech startup. They are planning sole-proprietor small businesses: convenience stores, cafés, unmanned retail shops, Korean restaurants, hair salons, laundromats. For this kind of relocation, D-8 is not the right visa — a different category applies.

Korea maintains a separate visa track for foreign sole proprietors: D-9-4 and D-9-5.

D-9-4 does not involve setting up a corporation. The applicant registers a business under their own name as a sole proprietor. Nationality is unrestricted, and the range of eligible industries is extremely broad.

D-9-5 is a special-track visa for former international students who graduated from a Korean university. It allows those who completed their studies in Korea to continue in Korea as entrepreneurs rather than return home, with a substantially lower investment threshold.

Lawyeon Visa & Immigration Center specializes in D-9-4 and D-9-5 — the sole-proprietor Business Immigration track for foreign nationals. We integrate the regulatory, contractual, and operational aspects of Korean sole-proprietor immigration into a single project, and this is our dedicated practice area.

When discussing the sole-proprietor track, another essential point is Korea's small-business support ecosystem.

The Korean government operates a range of programs for small business owners, including low-interest policy loans, guarantee-backed financing, business stabilization grants, and emergency assistance funds. These programs are administered by the Korea Small Enterprise and Market Service (SEMAS), under the Framework Act on Small Enterprises. Nationality is not a distinguishing factor: any sole proprietor that meets the statutory small-enterprise criteria — such as the employee-count threshold — is eligible on the same terms, whether Korean or foreign. A foreign national who has completed sole-proprietor business registration becomes eligible for the same support, on the same conditions, as a Korean small business owner.

Once D-9-4 or D-9-5 is on the table and the idea of relocating to Korea as a sole proprietor becomes concrete, the next question is naturally: "What business, and how?"

From the perspective of someone moving to Korea, the Korean market is unfamiliar territory. The dynamics of commercial districts, consumer behavior, raw-material supply chains, distribution practices, licensing procedures, and labor management conventions all differ from those at home. The Korean-language information environment compounds the difficulty. Selecting an industry, picking a location, securing suppliers, arranging interior construction, hiring staff, and designing marketing — doing all of this from abroad, the same way one might in a familiar home market, is simply not feasible. What makes it more demanding still: all of these decisions must be made before relocating, because the visa cannot be issued without a registered business and a signed commercial lease.

Given these constraints, the realistic option for a foreign applicant is to enter a business model that is already structured. One where operational playbooks are standardized, supply chains and ordering systems are centralized at the headquarters level, and location selection and interior design follow an established template. A business, in short, that fits the profile of a franchise.

Among the major markets worldwide, the Korean franchise sector is one of the most highly standardized in terms of business structure.

The Korean franchise market is not just voluntarily standardized. Korean law requires franchise headquarters to disclose the actual state of their business to prospective franchisees. The governing statute is the Fair Transactions in Franchise Business Act, and the central mechanism is the Franchise Disclosure Document (정보공개서).

The disclosure document is filed with and published on the Korea Fair Trade Commission's official portal, and the headquarters is legally obligated to provide it to a prospective franchisee at least 14 days before contract signing.

The content of the disclosure document is of a different character from marketing brochures. It breaks down costs by category — licensing, training, interior construction — and discloses the headquarters' financial status, any legal violations by its executives, average revenue per franchise store, opening rates, closure rates, and the number of dispute-mediation cases between headquarters and franchisees. It is a legally mandated disclosure — meaning even unfavorable figures must be published.

This framework effectively closes the information asymmetry between a franchise headquarters and a prospective franchisee by law. For a foreign applicant, the mechanism is especially valuable: marketing brochures alone make it hard to assess a headquarters' true condition, but the standardized disclosure fields allow multiple headquarters to be compared on a like-for-like basis. In our project design phase, we apply an internal screening model to exclude headquarters with unstable financials or abnormally high closure rates, and we analyze the disclosure document with the client together.

This concludes the overview of Korean Business Immigration visas and the reasons franchise businesses are a practical route along that path. From the next episode onward, we move into what is actually required to prepare.
