D-8 Business Investment Visa: Complete Guide to Application and Required Documents

The D-8 Business Investment Visa is issued to foreign nationals who invest 100 million KRW or more in a Korean corporation and take on management, administrative, or specialized technical roles in that entity. The stumbling block is rarely the number of documents — it's convincing the reviewing officer that the 100 million KRW is capital genuinely deployed in the business. Simply submitting a bank balance certificate almost never gets approved.

In actual screening, the overseas remittance route, the deposit into a domestic corporate account, the foreign-invested company registration, the office lease, and the specificity of the business plan all need to connect in one coherent storyline. No matter how many documents you file, a weak narrative here will unravel everything — and conversely, even a lean file gets approved quickly when the source of funds and the real substance of the business are crystal clear. The core idea is this: D-8 is a visa that turns the story of money into documented evidence.

1. D-8 Visa Basics and Three Subtypes

The D-8 looks like a single visa, but in practice it splits into several subtypes. The subtype you apply under dictates the required documents, equity ratio, and key review points.

1-1. D-8-1 Corporate Investment

For applicants taking on management, administrative, or production roles at a foreign-invested company registered under the Foreign Investment Promotion Act. This is by far the most common subtype, and an investment of 100 million KRW or more is the baseline requirement.

1-2. D-8-2 Venture Investment

For those who have invested in a Korean venture company or who serve as the CEO of a venture firm they founded themselves. Because venture certification must be secured in advance, the requirements are stricter than for ordinary corporations.

1-3. D-8-3 Trade Management

For sole proprietors running a trading business in Korea. The defining difference from the first two subtypes is that the applicant operates as an individual, not through a corporation.

1-4. D-8-4 Technology Startup

For foreign nationals with intellectual property rights or original technology who start a company in Korea. This subtype often links up with programs like OASIS — investment thresholds are relaxed, but applicants undergo a technology assessment.

2. Eligibility: 100M KRW Investment and Foreign Investment Registration

With the D-8-1, the most common question is "Why exactly 100 million KRW?" Under the Enforcement Decree of the Foreign Investment Promotion Act, 100 million KRW is the minimum amount recognized as foreign investment. Only when that amount is invested can a company be registered as a foreign-invested company — and without that registration certificate, the D-8 cannot be issued.

2-1. What the 100 Million Really Means

The 100 million is not paid-in capital in the abstract — it refers to the foreign currency actually remitted from overseas by the foreign national. Funds borrowed inside Korea, or KRW already sitting in a domestic account, do not count as foreign investment. The money must enter Korea as foreign currency and pass through a foreign exchange bank's foreign investment declaration and remittance receipt procedure.

2-2. Equity Ratio Requirement

On top of the 100 million minimum, the applicant must hold at least 10% of voting shares. For example, in a company capitalized at 500 million KRW, an investment of 100 million yields a 20% stake — satisfying the requirement. If the paid-in capital is pushed too high, the 10% threshold can break, so capital structure should be designed upfront at the incorporation stage.

2-3. Business Premises Requirement

The business premises must be an independent space separate from the applicant's residence. Co-working offices are accepted, but the space must be usable for actual business operations, and the lease contract must list the corporation as the tenant. Leases under the representative's personal name frequently cause problems.

3. Full List of Required Documents and Practical Checks

Documents break into four groups: ① applicant's personal documents ② corporate documents ③ investment evidence ④ proof of real business substance. Each group has its own common blind spots.

3-1. Personal Documents

• Visa application form (or application for change of status)
• Original passport and copy
• One standard-size photograph
• Criminal record certificate from home country (apostilled or consular-certified, issued within the last 6 months)
• Proof of education and work history (to demonstrate the link between the applicant's background and the business)

3-2. Corporate Documents

• Corporate registration certificate
• Business registration certificate
• Corporate seal certificate
• Shareholder register
• Articles of incorporation

3-3. Investment Evidence

• Foreign-invested company registration certificate
• Foreign exchange purchase certificate or overseas remittance confirmation
• Proof that investment funds were deposited (corporate account deposit evidence)
• Evidence of share issuance and subscription

3-4. Proof of Business Substance

• Lease agreement for the business premises
• Interior and exterior photos of the premises
• Business plan
• Recent financial statements (opening balance sheet for newly incorporated companies)
• Client contracts and tax invoices (if any)

4. Proving Source of Funds: The First Real Hurdle

Before anything else in a D-8 review, officers look at the origin of the money. This is where real applications diverge from rejected ones. What matters more than documents is whether you can explain, in one sentence, "where this 100 million came from and why it moved now."

4-1. Accepted Sources of Funds

• Salary or business income accumulated over years in the applicant's own overseas account
• Proceeds from selling real estate (with sales contracts and final payment receipts)
• Inheritance or gifts (with filing and tax evidence)
• Dividends from an overseas corporation (with dividend resolutions and tax records)

4-2. Fund Flows That Raise Suspicion

• A large sum deposited into the applicant's account shortly before remittance
• Routing through a third party's account with no explanation
• Deposited in cash and immediately remitted
• The remitter's name differs from the shareholder's name

4-3. How to Structure the Evidence

The cleanest way to show the source of funds is to narrate along a timeline. Pay slips from three years ago → accumulated balance in the home-country account → withdrawal at the time of remittance → deposit into the Korean corporate account — each step should interlock with the next. When this narrative is weak, even a thick pile of documents will trigger requests for additional explanation.

5. Step-by-Step Process from Incorporation to Visa Issuance

Because an out-of-order step often means rebuilding documents from scratch, the sequence itself is a big part of the prep time.

5-1. Standard Procedure Flow

5-2. Change of Status While in Korea

If you are already in Korea on another status such as D-10 or D-4, you can file for a change of status of stay instead. In that case the Certificate of Confirmation step is skipped, and immigration issues the decision directly.

5-3. Realistic Total Timeline

From the very beginning to receiving the visa typically takes two to three months. If correction notices are issued due to document errors, the process can easily stretch an extra month or more.

6. Writing the Business Plan: Persuasion over Length

With business plans, persuasiveness shows before length does. A concise five-page plan built around specific numbers has a higher approval rate than a flashy thirty-page deck.

6-1. What Reviewers Actually Look At

• Is this business viable as a legal line of work in Korea?
• Are revenue projections backed by real evidence?
• Where will the 100 million KRW actually go?
• Is the hiring plan realistic?
• Do the applicant's background and the business concept connect?

6-2. Sections the Plan Must Include

1. Company overview and business concept
2. Market analysis and competitive landscape
3. Product or service details
4. Three-year revenue and cost projections
5. Funds usage plan (the most important section)
6. Staffing plan
7. CEO's background and its connection to the business

6-3. Commonly Overlooked Points

In the funds usage plan, you need to break down where the 100 million actually gets spent with specific numbers — e.g., "Office rent: 30M, payroll: 40M, equipment: 20M, working capital: 10M." When this section is vague, the entire business plan reads as abstract.

7. Stay Period, Extensions, and Family Accompaniment

7-1. Initial Stay Period

The first D-8 is typically granted in increments of one to two years. Because the length is set based on early-stage business stability, the realism of your business plan affects how long the initial stay runs.

7-2. What Reviewers Check at Extension

Three issues cause the most trouble at the extension stage.

1. Virtually no revenue has been generated
2. No visible trace of the investment funds being used in the business
3. Not a single employee enrolled in the four major insurances

Even if money is sitting in the account, a weak flow-of-funds narrative can block the extension. Even when revenue is small, consistent signs of business operation — tax invoices, insurance enrollments, rent payments — need to accumulate over time.

7-3. F-3 Family Accompaniment

A D-8 holder's spouse and minor children can enter Korea together on an F-3 accompanying visa. F-3 holders are generally barred from employment, but there are no restrictions on children's education or spousal cohabitation. If the spouse wants to work, they'll need a separate activity-outside-status permit or to move up to F-2 or F-5.

7-4. Path to Permanent Residency and Naturalization

After staying on a D-8 for a certain period, applicants can progress to F-2 (long-term residence) → F-5 (permanent residence) → citizenship. CEOs of foreign-invested companies have a fast track directly to F-5 — if investment size and local hiring levels meet specified thresholds, permanent residency can be obtained right away. Standards change periodically, so confirmation with the relevant authorities is necessary.

8. Common Mistakes and Reasons for Denial

In practice, about 70% of denials fall into the same patterns.

8-1. Assembling the Fund Flow After the Fact

Rushing to incorporate first and then scrambling to fit a source-of-funds story afterwards. When the sequence is reversed, the gap between remittance timing and business timing becomes very hard to explain away.

8-2. Premises That Exist Only on Paper

Registering just the address of a co-working space without even a physical desk gets caught immediately during an on-site inspection. Signage, a workstation, interior photos, and mail-receipt records need to be there together.

8-3. Parking Funds in the CEO's Personal Account

Investment funds must be deposited into the corporate account. Routing through the CEO's personal account makes foreign investment recognition difficult and creates temporary-receivable issues on the tax books.

8-4. Disconnect Between Business Concept and Background

When someone who has spent their career in IT suddenly announces they're opening a restaurant, reviewers start doubting the sincerity of the plan. There needs to be at least one concrete thread linking career to business.

8-5. Errors on the Criminal Record Certificate

If the home-country criminal record certificate lacks an apostille or consular authentication, even a valid original will be rejected at intake. The requirement that the certificate be issued within the last six months also trips up many applicants.

9. Frequently Asked Questions (FAQ)

Q1. Do I have to remit the 100 million KRW all at once? A. In principle, the full declared foreign investment amount must enter Korea in foreign currency before foreign-invested company registration is possible. Split remittances are allowed, but by the time of registration, at least 100 million must have arrived cumulatively. If only part has been received, registration is put on hold.

Q2. Can I convert an existing sole proprietorship in Korea into a corporation to qualify for D-8? A. It's possible, but tricky. You'd need to contribute the sole proprietorship's assets in-kind to the corporation and separately remit 100 million KRW in foreign currency — the existing sole proprietorship itself doesn't count as D-8 investment. Starting a fresh corporation is usually cleaner in practice than converting.

Q3. Is it fine to co-found the company with a Korean partner? A. Co-founding is fine in itself. However, the foreigner's stake must be at least 10% of voting shares, and your personal contribution must be 100 million or more. If the Korean partner's stake is too large, the foreign-invested company requirement can break, so capital structure needs to be planned in advance.

Q4. Can I work on a D-8 at a company other than my own? A. In principle, a D-8 permits you to work only at the registered foreign-invested company. Working elsewhere requires a separate activity-outside-status permit — moonlighting without one violates the Immigration Act.

Q5. Will my extension be denied if my company has no revenue at all? A. Not automatically. What matters more than the absence of revenue is how the investment funds are being deployed. If there are steady traces of business activity — rent, payroll, equipment purchases, marketing — and a concrete revenue plan going forward, extensions do get granted. However, if both revenue and spending remain negligible for two consecutive years, you'll hit a wall.

10. Consultation

D-8 is a visa where the story of your funds and the substance of your business show up before the document count does. Once the incorporation sequence goes off course, you often have to backtrack at the foreign-invested registration step — and the source-of-funds evidence needs to be designed before remittance, not after. The three places where going it alone gets hardest are structuring the source-of-funds narrative, designing corporate capital, and tuning the business plan to the reviewer's perspective.

Vision Administrative Office handles D-8 business investment visa applications, incorporation, and foreign-invested company registration as one continuous workflow. We review from the earliest stage so that your funding structure and business plan lock together cleanly.
