Introduction: Your Gateway to Korea’s Startup Ecosystem
Dreaming of building your startup in Seoul? Korea’s OASIS (Overall Assistance for Startup Immigration System) program might be your golden ticket. Launched to attract global tech talent, OASIS offers foreign entrepreneurs a streamlined path to:
- Establish a company in Korea
- Secure long-term residency (D-8-4 visa)
- Access government funding and startup support
- Hire employees and scale operations
In 2026, Korea’s startup ecosystem is more welcoming than ever. With dedicated managers, English-language support, and expanded eligibility criteria, OASIS has become the preferred route for non-Korean founders.
This guide covers everything from eligibility to application steps, visa types, and insider tips to maximize your success.
What Is OASIS?
OASIS is a government-backed program managed by the Ministry of SMEs and Startups (MSS). It combines:
- Immigration pathways (D-10-2 and D-8-4 visas)
- Startup education (business courses, mentorship)
- Networking support (investor introductions, corporate partnerships)
- Funding access (government grants, VC connections)
Think of it as a one-stop shop for foreign entrepreneurs. Instead of navigating Korea’s immigration and business systems separately, OASIS integrates both.
Why Choose OASIS Over Other Visa Routes?
| Feature | OASIS (D-8-4) | Standard D-8 Visa | D-10 Job Seeker Visa |
|---|---|---|---|
| Requires Korean company | ✅ (after prep period) | ✅ | ❌ |
| Initial duration | 1 year (renewable) | 1 year | 6 months |
| Startup education | ✅ | ❌ | ❌ |
| Government support | ✅ | ❌ | ❌ |
| Path to F-2/F-5 residency | ✅ | ✅ | ⚠️ (limited) |
| Application difficulty | Medium | High | Low |
Bottom line: OASIS offers the best balance of support, flexibility, and long-term residency potential for foreign founders.
The Two-Stage OASIS Process
OASIS operates in two stages:
Stage 1: D-10-2 Visa (Startup Preparation)
Purpose: Test your idea, build your team, and prepare to launch.
Duration: 6 months (extendable to 2 years total)
What you do:
- Attend OASIS courses (entrepreneurship, Korean business culture)
- Develop your business plan
- Network with investors and mentors
- Complete legal/financial setup (virtual office, bank account)
What you can’t do:
- Officially operate a business (no revenue generation)
- Hire employees
- Sign commercial contracts
The D-10-2 is essentially a startup prep visa—you’re building the foundation, not running the company yet.
Stage 2: D-8-4 Visa (Technology Startup)
Purpose: Officially operate your Korean startup.
Duration: 1 year initially, renewable indefinitely (as long as the business performs)
What you can do:
- Run your registered Korean company
- Hire employees (including foreign talent)
- Generate revenue and seek investment
- Apply for government grants
Requirements to transition from D-10-2 to D-8-4:
- Complete OASIS courses (minimum 100 hours)
- Secure an OASIS recommendation letter
- Register your company (LLC or Corporation)
- Prove business viability (business plan, initial funding)
Eligibility: Who Can Apply?
Educational Requirements
Option 1: University Degree
- Bachelor’s degree or higher from an accredited university
- Must be apostilled (Hague Apostille Convention) or legalized by Korean embassy
Option 2: Professional Experience
- 3+ years of relevant work experience in tech/startups
- Proof required: reference letters, employment contracts, portfolio
Option 3: Exceptional Talent
- Patent holders
- Award winners (hackathons, startup competitions)
- Published researchers in relevant fields
Business Idea Requirements
Your startup must focus on technology or innovation:
- ✅ Software development, AI/ML, fintech
- ✅ Biotech, healthtech, medtech
- ✅ Hardware (IoT, robotics, electronics)
- ✅ Clean energy, sustainability
- ⚠️ E-commerce (only if tech-driven, e.g., AI-powered platforms)
- ❌ Traditional retail, restaurants, real estate
2026 update: OASIS now accepts climate tech and social impact startups with clear technology components.
Nationality and Age
- Any nationality (no restrictions)
- No age limit (though most applicants are 20-45)
- Physical presence required: You must apply in Korea (not from abroad)
Entry Strategy
How do you get to Korea to apply?
Option 1: Tourist visa → D-10-2
Most common route:
- Enter Korea on a tourist visa (90 days visa-free for many countries)
- Apply for D-10-2 while in Korea
- Convert your tourist status to D-10-2 within 60 days
Option 2: Other visa → D-10-2
If you’re already in Korea on:
- Student visa (D-2)
- Work visa (E-series)
- Working holiday visa (H-1)
You can transition directly to D-10-2 by submitting your OASIS application.
Note: You cannot apply from abroad. OASIS requires in-person attendance at courses and interviews.
Application Process: Step-by-Step
Step 1: Submit OASIS Application
Where: www.oasisvisa.com or www.startup-korea.com
Required documents:
- Passport (valid 6+ months)
- University degree (apostilled) or work experience proof
- Business plan (5-10 pages, English or Korean)
- Resume/CV
- Proof of financial means (KRW 10 million+ in bank, ~USD 7,500)
Processing time: 2-4 weeks for initial review
Step 2: Attend OASIS Courses
Once accepted, you’ll attend:
- Entrepreneurship courses (business model design, lean startup)
- Korea business culture (negotiation, networking etiquette)
- Legal/tax basics (company registration, visa compliance)
Format: Hybrid (online + in-person)
Time commitment: 100 hours over 3-6 months
Location: Seoul (main hub), Busan, Daejeon (regional centers)
Step 3: Secure Recommendation Letter
After completing courses, OASIS evaluators review your:
- Business plan
- Market research
- Team composition
- Financial projections
If approved, you receive an OASIS recommendation letter—essential for visa applications.
Success rate: ~70% for applicants who complete courses seriously
Common rejection reasons:
- Vague business plan (no clear value proposition)
- Non-tech business idea (e.g., traditional services)
- Insufficient financial backing
Step 4: Apply for D-10-2 Visa
Where: Korean Immigration Office (nearest to your location in Korea)
Documents:
- OASIS recommendation letter
- Completed visa application form
- Passport photos (3.5cm x 4.5cm)
- Health insurance proof
- Residence agreement (lease or hotel booking)
Fee: KRW 60,000 (~USD 45)
Processing time: 1-2 weeks
Step 5: Register Your Company
While on D-10-2, prepare for company registration:
- Choose business structure (LLC vs. Corporation—see our complete guide)
- Register with Korean tax office
- Open corporate bank account
- File FDI notification (if foreign-funded)
Timeline: 4-8 weeks (if you do it yourself), 2-3 weeks (with legal assistance)
Step 6: Apply for D-8-4 Visa
Once your company is registered:
Documents:
- Company registration certificate
- Business license
- Lease agreement (office/virtual office)
- Financial statements (initial capital proof)
- Updated business plan
Processing time: 2-3 weeks
Fee: KRW 100,000 (~USD 75)
D-8-4 Visa: Renewal and Long-Term Strategy
Renewal Requirements
To renew your D-8-4 annually, you must prove:
- Business activity: Revenue, contracts, or active development
- Financial stability: Bank statements showing operational funds
- Compliance: Tax filings, social insurance payments
2026 standards (stricter than before):
- Year 1: Proof of concept (prototype, beta users)
- Year 2: Revenue or external funding (VC, government grant)
- Year 3+: Profitability or clear path to profitability
Immigration officers now scrutinize substance:
- Do you have real office space? (Virtual offices are acceptable in Year 1 only)
- Do you have employees? (At least 1-2 by Year 2)
- Are you paying yourself a salary? (Recommended: KRW 2-3 million/month minimum)
Insider tip: Keep meticulous records—bank statements, contracts, invoices. Immigration loves documentation.
Path to Permanent Residency
D-8-4 → F-2-7 (Points-Based Residency)
After 3+ years on D-8, you can apply for F-2-7 if you meet:
- Age, education, income, and Korean language points (80+ total)
- Detailed guide: F-2-7 Points-Based Visa 2026
D-8-4 → F-5 (Permanent Residency)
After 5 years on D-8 or 3 years on F-2, you can apply for F-5 if:
- Business generates consistent revenue
- You’ve paid taxes and social insurance
- No immigration violations
OASIS Success Stories (2026)

Founder: Maria, Brazil (30 years old)
Journey:
- Entered Korea on tourist visa (2025)
- Applied for D-10-2 via OASIS
- Completed courses in 4 months
- Registered LLC (KRW 50 million capital)
- Secured D-8-4 (2026)
- Raised KRW 300 million seed round from Korean VC
Key to success: Strong demo product (working AI model) before applying for D-8-4.
Case 2: Biotech Diagnostics
Founders: Alex & Sam, USA (35, 38 years old)
Journey:
- Both had PhDs in biology
- Applied for D-10-2 individually
- Partnered during OASIS courses
- Co-founded Korean Corporation (KRW 100 million capital)
- Hired 2 Korean researchers
- Won government grant (KRW 200 million)
Key to success: Leveraging academic credentials + Korean co-founder network from OASIS.
Case 3: Climate Tech (Failed, Then Succeeded)
Founder: Jean, France (42 years old)
Journey:
- Applied for D-8-4 directly (without OASIS) → Denied (no recommendation letter)
- Re-applied via D-10-2 → Accepted
- Refined business plan during OASIS courses
- Registered LLC (KRW 30 million capital)
- Secured D-8-4 on second attempt
Lesson: OASIS dramatically improves approval odds. Don’t skip it.
Common Pitfalls to Avoid
1. Underfunded Business Plans
Mistake: “I’ll raise money after I get the visa.”
Reality: Immigration wants proof you can survive 12+ months. Show:
- Personal savings (KRW 20-30 million minimum)
- Pre-seed funding (friends & family, angel investors)
- Revenue potential (letters of intent from customers)
2. Ignoring Substance Requirements
Mistake: Virtual office + no employees + no revenue = renewal denied.
Solution: By Year 2, have:
- Real office or co-working space
- At least 1 employee (even part-time)
- Signed contracts or paying customers
3. Poor Korean Language Skills
Mistake: “Everyone speaks English in Korea.”
Reality: Immigration interviews, tax office visits, and bank interactions often require Korean.
Solution: Learn basic business Korean (Level 2-3 TOPIK). OASIS offers Korean classes—take them seriously.
4. Late Tax/Insurance Filings
Mistake: “I’ll file taxes next year.”
Reality: Immigration checks tax compliance annually. Even if your revenue is zero, file on time.
Solution: Hire a Korean tax agent (KRW 500,000-1,000,000/year) from Day 1.
FAQ: Your OASIS Questions Answered
Q1: Can I apply if I’m over 50?
Yes. No age limit. However, older applicants should emphasize proven track record (previous successful startups, industry expertise).
Q2: Do I need to know Korean?
Not initially. OASIS courses are in English. But for long-term success, learning Korean is highly recommended.
Q3: Can I bring my family?
Spouse & children: Yes, on F-3 dependent visas (after you secure D-8-4).
Parents: No (unless you transition to F-2/F-5 later).
Q4: How much does OASIS cost?
- OASIS courses: Free
- Visa fees: ~KRW 160,000 total (D-10-2 + D-8-4)
- Company registration: KRW 500,000-1,500,000 (DIY or with lawyer)
- Living expenses: KRW 1,500,000-3,000,000/month (Seoul)
Total first-year budget: KRW 30-50 million (~USD 22,500-37,500) including capital.
Q5: What if my startup fails?
If your business closes:
- You have 3 months to find another visa path (e.g., employment visa, new startup)
- You cannot stay on D-8-4 indefinitely without business activity
- Consider pivoting to a new startup idea while on D-8-4 (instead of closing)
Q6: Can I work part-time while on D-10-2?
No. D-10-2 doesn’t allow employment. You must rely on savings or external funding.
Exception: Teaching English or freelancing is not allowed without separate work permit.
2026 Updates: What’s New?
Expanded Eligibility
- Climate tech and social impact startups now qualify
- Non-degree holders with 5+ years experience (previously 3 years minimum)
Faster Processing
- D-10-2 approval: 2 weeks (down from 4 weeks in 2025)

Dedicated Support
- English-speaking case managers assigned to each OASIS cohort
