D-8-4 Technology Startup Visa: Complete Guide to Eligibility and Application Process

The D-8-4 is designed for foreign founders who cannot meet the 100 million KRW capital threshold but can prove their qualifications through technical expertise and intellectual property. While the standard D-8-1 is a visa that demonstrates the flow of money, the D-8-4 is a visa that shows whether your academic background, technical skills, and patents, trademarks, or copyrights can actually be commercialized. Eligibility branches into two main tracks: a bachelor's degree or higher + completion of OASIS (Overall Assistance for Startup Immigration System) training, or ownership of intellectual property rights.

The step that trips up most applicants in practice isn't the number of documents but rather explaining "why this business qualifies as a technology startup." Holding up a single patent doesn't automatically make you a D-8-4 candidate — the patent must clearly tie to the corporation's actual business operations. Below, we'll walk through eligibility requirements, documents, the OASIS points system, application procedures, differences from D-8-1, and common reasons for rejection.

1. What Is the D-8-4 Technology Startup Visa

The D-8-4 refers to the technology startup (OASIS) track within the D-8 Corporate Investment visa category. Unlike the standard D-8-1 for general corporate establishment or the D-8-2 for venture enterprises, the D-8-4 recognizes the founder's intellectual property and academic credentials as a substitute for capital. Its official name is "Technology Startup," and it is categorized as a subclass of D-8 Corporate Investment under Attached Table 1-2 of the Enforcement Decree of the Immigration Act.

1-1. What Makes It Different

The biggest difference is that the 100 million KRW minimum investment requirement does not apply. However, the corporation must already be established, and the applicant must serve as CEO or a registered director of that corporation. While there is theoretically no limit on capital amount, in practice a minimum operating fund sufficient to sustain the corporation is required.

1-2. Who Uses This Visa

• Foreign nationals who hold a bachelor's degree or higher from a Korean or overseas university
• Foreign nationals who hold intellectual property rights (patents, utility models, designs, trademarks) registered in Korea under their own name
• Foreign founders looking to launch IT, bio, content, or manufacturing-based startups

The most common pathway is entering Korea on a D-10 job-seeker visa, completing startup preparations, and then changing status to D-8-4.

2. Detailed Eligibility Requirements

D-8-4 eligibility branches into two main tracks: degree-based + OASIS points and intellectual property-based. Satisfying just one qualifies you to apply, but in practice applicants who meet both conditions have higher approval rates.

2-1. Academic Requirements

You can apply even if your major is unrelated to technology. However, if the link between your business item and your degree major is weak, reviewers will question whether this truly qualifies as a technology startup. A weak connection here often derails the application.

2-2. Intellectual Property Requirements

You must hold at least one of the following Korean-registered patents, utility models, design rights, trademarks, or copyrights under your own name. Pending applications are generally not accepted — the right must have been granted a registration number.

• Patents: Highest point value and smoothest review
• Utility models: Lower than patents but accepted
• Designs / trademarks: Weak on their own, strong when combined with a patent
• Copyrights: Software registration certificates, content copyright registration certificates

Foreign-granted patents must be converted into a Korean Intellectual Property Office registration. Holding only a USPTO patent, for example, does not automatically qualify you for the D-8-4.

2-3. Corporate Requirements

• Corporate registration complete (stock company or limited liability company)
• Applicant serves as CEO or co-representative
• Secured physical business address (virtual offices are generally not accepted)
• Business registration certificate issued

3. OASIS Startup Immigration System and the Points Scheme

D-8-4 applications accumulate points through the OASIS (Overall Assistance for Startup Immigration System) program operated by the Ministry of Justice. It's not simply a yes/no check on eligibility — accumulating 80 points or more is effectively the passing line.

3-1. Points Category Overview

Point allocations are subject to change, so confirm with the competent Immigration Office just before filing.

3-2. OASIS Training Completion

OASIS is organized in stages: OASIS-1 (basic training), OASIS-2 (advanced), OASIS-3 (mentoring), OASIS-4 (competition), and OASIS-5 (corporate establishment support). Completing at least OASIS-1 is a prerequisite for a D-8-4 application, and in practice most applicants complete OASIS-2 as well.

3-3. Points Strategy

If you hold only a bachelor's degree and no patent, reaching 80 points is tight. In that case, the plan is to raise your TOPIK score, win a startup competition, or attract investment to fill the gap. The practical approach is to lay out the points table and start plugging the weakest categories first.

4. Complete Document Checklist

4-1. Core Documents

4-2. Filing Abroad vs. Domestic Status Change

If you are entering Korea anew from overseas, you begin by filing for a Certificate for Confirmation of Visa Issuance (CCVI). If you are already staying in Korea on a D-2 (student), D-10 (job-seeker), or E-series visa, you file for a change of status. The document set is nearly identical, but domestic status changes additionally require evidence of compliance with your current status (enrollment certificates, transcripts, records of job-seeking activity, etc.).

4-3. Writing the Business Plan

With business plans, persuasiveness matters more than length. Reviewers look at the following first:

1. Link between the core technology and your IP — How is the patent integrated into the product/service?
2. Market size and target customers — Concrete targets, not vague "global expansion"
3. Revenue model and three-year revenue projection — Numbers with evidence
4. Contribution to the Korean economy — Hiring plans for domestic employees, export potential
5. Funding plan — Real sources of initial operating capital

Vague phrases like "responding to the Fourth Industrial Revolution" are more likely to hurt than help. The connection between your patent claims and your business must be spelled out in writing.

5. Application Process Step by Step

The total timeline runs roughly two months at fastest, and three to five months on average, depending on how far along your preparations are. Because OASIS training is offered on a quarterly schedule, the overall timeline shifts substantially based on when you start training.

5-1. Hi Korea Advance Booking

All applications for status change and CCVI require advance booking through the Hi Korea portal. At the Seoul Immigration Office in particular, bookings are often backed up four to six weeks, so you should prepare documents and book in parallel.

5-2. Preparing for On-Site Inspection

To curb abuse of the technology startup track, the Ministry of Justice has been increasing on-site inspection rates. Inspections verify the following:

• Whether the office is actually in operation (furniture, equipment, computers, signs of use)
• Whether the CEO actually works there
• Whether the posted company name matches the registered name
• Whether bank account activity aligns with business operations

6. Comparing D-8-1, D-8-2, and D-8-4

6-1. Differences Among the Three Types

6-2. Which Is More Advantageous

If you can actually remit 100 million KRW in capital, D-8-1 is faster and cleaner. If you want to leverage technology and your degree rather than money, D-8-4 is more favorable. If your business can qualify for venture certification, D-8-2 is worth considering, but since venture certification itself is a separate process, D-8-4 is more realistic in the early startup phase.

6-3. Potential to Switch

One viable strategy is to enter and launch under D-8-4 initially, and once the business grows, add a foreign investment notification to convert to or run in parallel with D-8-1. Your visa status is not set in stone.

7. Stay Period, Extension, and Family Accompaniment

7-1. Initial Period of Stay

The initial D-8-4 approval is usually granted in one-year increments. As performance accumulates, extensions of up to two years become possible. Occasionally a two-year term is granted from the start, but this is rare.

7-2. Key Points for Extension Review

At extension time, the reviewer's first three checks are:

• Whether revenue has been generated — A continuous 0-won revenue track record makes extension difficult
• Labor expenses — Whether there are employees enrolled in social insurance
• Tax compliance — History of VAT and corporate tax filings

Low revenue in the early stage is understandable, but the key point is that if there is no trace of operations whatsoever, the corporation is treated as having no real substance.

7-3. Family Accompaniment (F-3)

Spouses and minor children of a D-8-4 holder can stay together on an F-3 dependent visa. Since F-3 does not allow employment, a spouse who needs to work must look into a separate status (such as E-7). Children can attend elementary, middle, and high school on F-3.

7-4. Progression to F-2-7

While residing on D-8-4, accumulating enough points allows you to change to F-2-7 (points-based residency), and after five or more years on F-2 you can apply for F-5 permanent residency. If you're planning for long-term settlement, it pays to map out this route in advance.

8. Common Mistakes and Reasons for Rejection

8-1. The Misconception That a Patent Is All You Need

Many applicants assume a patent registration certificate alone will secure D-8-4 approval. What reviewers actually examine is the real-world connection between the patent's technical content and the business item. If your patent claim covers Technology A but your corporation's main business is Distribution B, the case for a technology startup falls apart.

8-2. Shared-Office-Only Addresses

It's common to use a shared office for the convenience of incorporation, but if there's no actual desk or sign of use, this leads to rejection. At a minimum, you need a lease that specifies a dedicated unit number, along with photos showing actual use of that unit.

8-3. Submitting a Generic Business Plan Template

Pasting in template text from the internet is easy to spot. Unsupported numbers like "aiming to capture 20% of the domestic market" actually work against you. It's better to keep it small but concrete — that path is closer to approval.

8-4. Inflated OASIS Point Counts

It's common for an applicant's self-calculated score to diverge from the score the reviewer assigns. If a patent is jointly filed, recently transferred, or granted only overseas, the points don't carry over as expected. Before finalizing your score, match each official category against your actual documents one by one.

8-5. Setting Capital Too Low

Because there's no capital requirement, some applicants form a corporation with just one million KRW, which raises the suspicion: "Can a corporation that can't even pay its office rent actually run a business?" In practice, having around 30 million KRW in capital plus initial operating funds in the account is the safer option.

8-6. Violations of Current Visa Status

If you failed to properly report job-seeking activity during D-10 status, or exceeded the part-time work limit as a D-2 student, you'll be penalized during the status change. Whether you've faithfully complied with your current visa status is also a review point.

9. Frequently Asked Questions (FAQ)

Q1. My patent is still pending — can I apply for D-8-4 before it's granted?

A. As a rule, only fully registered intellectual property rights are recognized. Patents that are still under examination are not counted in the OASIS points system. That said, if you can exceed 80 points through a bachelor's degree, TOPIK scores, and completed startup training, you can still apply without a patent. When going without a patent, the technical merit section of your business plan must be significantly more detailed.

Q2. Are doctoral degrees earned abroad recognized?

A. Yes. However, you need the original degree certificate and transcript with an apostille or Korean consular confirmation, and foreign-language documents must be accompanied by a notarized translation. Degrees earned through online programs or from unaccredited schools face stricter scrutiny.

Q3. I'm currently on a D-10 job-seeker visa — can I switch directly to D-8-4?

A. Yes. In fact, the D-10 → D-8-4 change is the most common pathway. You may, however, be asked to verify whether you've been properly reporting job-seeking activity during your D-10 stay. You file for a status change after completing corporate establishment, business registration, and OASIS points calculation.

Q4. How much capital should I set for a favorable review?

A. There's no statutory minimum, but 30 to 50 million KRW or more is recommended. Your capital should be enough to cover office rent, six months of operating expenses, and initial marketing costs — that's the level at which your corporation is considered to have "real substance." If capital is too low, reviewers will doubt your ability to sustain the corporation.

Q5. Can I change my business item after D-8-4 approval?

A. Switching to a completely different industry can jeopardize your D-8-4 status. This is because the very identity of "technology startup" gets shaken. Expanding within the scope connected to your existing intellectual property is less problematic, but when replacing your industry wholesale, confirm with the competent Immigration Office in advance.

10. Consultation Information

The D-8-4 has relatively few required documents, yet its approval rate is low. The reason is simple: too many applications lack the narrative that connects degree, patent, and business plan. No matter how strong your patent or how advanced your degree, if the explanation that ties these three into a single business is weak, the application falters at review.
