What is the OASIS Startup Visa?

The OASIS (Overall Assistance for Startup Immigration System) Startup Visa is South Korea’s specialized immigration program designed to attract innovative foreign entrepreneurs. Officially designated as the D-8-4 visa category, OASIS represents Korea’s commitment to building a vibrant startup ecosystem by removing traditional barriers that previously prevented talented international founders from establishing businesses in the country.

Unlike conventional business visas that require substantial capital investment or established business track records, the OASIS program focuses on entrepreneurial potential, innovative business ideas, and the founder’s commitment to building their venture in Korea.

Why OASIS Matters in 2026

Korea’s startup landscape has evolved dramatically over the past decade. The government recognizes that global talent drives innovation, and the OASIS program reflects this understanding. In 2026, the program offers foreign entrepreneurs:

Lower Entry Barriers: Traditional investment requirements that excluded early-stage founders have been significantly reduced under OASIS guidelines.

Integrated Support System: Beyond visa issuance, OASIS provides comprehensive business support including mentorship, networking opportunities, and connections to Korea’s venture capital ecosystem.

Pathway to Long-Term Residence: Successful OASIS visa holders can transition to other visa categories, including investment visas and eventually permanent residence, as their businesses grow.

Access to Government Programs: OASIS participants gain eligibility for various government startup support programs, grants, and incentives that would otherwise be unavailable to foreign entrepreneurs.

OASIS Eligibility Requirements

To qualify for the OASIS Startup Visa in 2026, foreign entrepreneurs must meet specific criteria:

Basic Qualifications

Non-Korean Nationality: The program specifically targets foreign nationals who wish to establish startups in Korea. Korean citizens and existing long-term residents with work authorization are not eligible.

Age Requirements: While there’s no strict age limit, applicants must be legally capable of establishing and managing a business (typically 19 years or older under Korean law).

No Criminal Record: Applicants must provide documentation proving they have no serious criminal history that would disqualify them from visa issuance.

Business Plan Requirements

Your business plan forms the core of your OASIS application. Korean immigration authorities and recommending institutions evaluate:

Innovation Potential: The business must demonstrate innovative elements—whether technological innovation, novel business models, or solutions to existing market problems.

Market Viability: Your plan should show realistic market analysis, target customer identification, and credible revenue projections.

Growth Scalability: OASIS prioritizes businesses with potential for growth beyond the initial launch phase, particularly those that could create employment or contribute to Korea’s economy.

Korea-Specific Rationale: You must explain why Korea is the right market for your business and how you plan to navigate the local business environment.

Recommendation System

The OASIS program operates through a recommendation system. To receive a D-8-4 visa, you must obtain recommendation from one of the designated organizations:

Each recommending institution has its own evaluation criteria and application process, though all assess innovation potential, feasibility, and the founder’s capabilities.

The OASIS Application Process

Step 1: Research and Preparation

Before applying, thoroughly research the Korean market and startup ecosystem. Attend startup events (many are now available online), connect with existing foreign entrepreneurs in Korea, and understand the competitive landscape for your business idea.

Prepare comprehensive documentation:

Step 2: Secure Recommendation

Apply to one or more recommending institutions. Each institution has application windows throughout the year, typically quarterly. The application process generally includes:

  1. Submission of Business Plan: Submit your comprehensive business plan and supporting documents through the institution’s application portal.

  2. Initial Screening: The institution reviews applications for completeness and basic eligibility.

  3. Interview/Pitch Session: Qualified applicants are invited to present their business plan, either in person or via video conference.

  4. Evaluation: A committee evaluates your application based on innovation, feasibility, market potential, and your capabilities.

  5. Recommendation Issuance: Successful applicants receive an official recommendation letter, which is essential for the visa application.

Step 3: Visa Application

Once you have your recommendation letter:

If You’re Outside Korea: Apply at the Korean embassy or consulate in your home country. Required documents typically include:

If You’re Already in Korea: You can apply for the D-8-4 visa at an immigration office if you’re currently on a visa that permits status change (such as tourist visa, student visa, etc.). Required documents are similar, with additional proof of legal stay.

Processing time typically ranges from 2-4 weeks, though this can vary depending on application volume and individual circumstances.

Step 4: Post-Arrival Requirements

After receiving your D-8-4 visa and arriving in Korea:

  1. Alien Registration: Register at your local immigration office within 90 days of arrival to receive your Alien Registration Card (ARC).

  2. Company Registration: Establish your business entity (typically a stock company 주식회사 or limited liability company 유한회사) with the Korean courts.

  3. Business Registration: Obtain business registration from the tax office.

  4. Bank Account: Open a corporate bank account (this can be challenging and may require multiple visits).

  5. Participate in OASIS Programs: Engage with the support services provided by your recommending institution.

Duration and Renewal

The initial OASIS D-8-4 visa is typically granted for 2 years. Renewal is possible as long as you continue operating your business and making reasonable progress toward your business goals.

For visa renewal, you’ll need to demonstrate:

Common Challenges and How to Overcome Them

Success Stories: OASIS Entrepreneurs in Korea

The OASIS program has supported hundreds of foreign entrepreneurs since its inception. Common patterns among successful OASIS visa holders include:

Cross-Cultural Bridges: Entrepreneurs who create value by connecting Korean markets with their home countries often find product-market fit quickly.

B2B Solutions: Foreign entrepreneurs bringing international best practices to serve Korean businesses have achieved notable success.

Community Building: Founders who actively engage with the Korean startup community, attend events, and contribute to the ecosystem tend to build stronger networks and access more opportunities.

2026 Outlook: What’s Changing

The Korean government continues refining the OASIS program based on participant feedback and policy objectives. In 2026, watch for:

Expanded Recommending Institutions: More universities, accelerators, and regional centers are joining as official recommending organizations, increasing geographic access.

Enhanced Support Services: OASIS programs are expanding mentorship, workspace subsidies, and connections to corporate partners.

Streamlined Processes: Digital transformation initiatives are making application and renewal processes more efficient.

Industry-Specific Tracks: Some recommending institutions are developing specialized tracks for specific industries (biotech, cleantech, AI) with tailored support.

Practical Tips for OASIS Applicants

Before You Apply

  1. Validate Your Business Idea: Test your concept before committing to the OASIS application. Can you acquire customers? Is there genuine market demand?

  2. Build Your Network Early: Join online communities of foreign entrepreneurs in Korea. Their insights are invaluable.

  3. Prepare Financially: Even with OASIS, you’ll need personal funds to support yourself for at least 6-12 months. Budget conservatively.

  4. Research Recommending Institutions: Different institutions have different strengths, application processes, and support services. Choose strategically based on your industry and needs.

During the Application

  1. Tell a Compelling Story: Your business plan should clearly articulate why your idea matters, why Korea, and why you’re the right person to execute it.

  2. Show Evidence: Where possible, demonstrate traction—customer interest, prototype development, market research, partnership discussions.

  3. Be Realistic: Overpromising in your business plan can create problems during visa renewal. Set achievable milestones.

  4. Prepare for Interviews: Practice explaining your business clearly and concisely. Expect questions about market size, competition, monetization, and your Korea strategy.

After Receiving Your Visa

  1. Hit the Ground Running: Use your first few months intensively to establish your business foundation, build networks, and make progress toward early milestones.

  2. Document Everything: Keep thorough records of business activities, expenses, progress toward goals. You’ll need this for visa renewal.

  3. Leverage OASIS Resources: The support programs aren’t just formalities—actively participate in mentorship, networking, and educational opportunities.

  4. Plan for Growth: Think ahead about how your business will evolve and what visa category you might transition to as you scale.
