Immigrating to South Korea as a foreign founder
Many foreign founders immigrate to Korea and start their startup journey in Seoul, one of the most vibrant and innovative cities the world. Korea also provides very robust technology infrastructure.
Many founders join Korea’s well-known startup immigration program, the Overall Assistance for Startups Immigration System (OASIS), expecting a smooth and straightforward process. At first glance, the official instructions appear clear, simple, and easy to follow.
Additionally, available online resources, although often outdated, can give the impression that securing a startup visa in Korea is relatively hassle-free.
Access the OASIS Program Hub for complete details on program information, schedules, and eligibility assessment.

The OASIS Program Journy
Once founders complete their first OASIS course, questions quickly begin to pile up:
- How do I calculate my points?
- What do my accumulated points mean for my startup visa application?
- How do I prepare my business plan?
- What is the correct business plan format?
- Which documents are required?
- How can I obtain the non-standard documents?
- What are the correct document names in Korean?
- How do I properly fill out the application forms?
And many more.
What initially feels like a straightforward process often becomes confusing and fragmented. Founders are left navigating a system where clear, consistent answers are hard to find; often with no single source providing complete, accurate guidance.
In many cases, even OASIS program providers themselves cannot offer definitive answers.
This is something I’ve personally observed while supporting members of my global startup CEO community as they navigate Korea’s startup visa process.
Common Reasons for OSIS Visa Rejections (D-8-4 & D-10-2)
Many founders assume that visa rejections happen because they don’t qualify. In reality, that’s often not the case.
Most rejections for the Korea Startup Visa (D-8-4) and D-10-2 visa occur due to a lack of preparation; not a lack of eligibility.
Below are some of the most common reasons applications get rejected:
- Insufficient or miscalculated points: The total score may appear correct, but it does not meet the internal eligibility criteria used by immigration
- Missing or incorrect application forms: Submitting outdated, inaccurate or even incorrectly filled forms can lead to immediate rejection.
- Incomplete documentation: Missing even a single required document can delay or invalidate your application.
- Lack of in-depth understanding of eligibility: Many founders don’t fully understand how their profile is evaluated—leading them to pay high fees to external consultants for guidance that often fails to clarify the process or speed up their application.
The False Confidence Trap
I recently spoke with a founder preparing for his D-8-4 startup visa in Korea while working through his application documents.
He was confident.
Confident that he had chosen the right path.
Confident that the expenses he was making were necessary.
Confident that everything was under control.
But as we went deeper into the conversation, a different picture started to emerge.
There were clear gaps in his approach; and more importantly, missed opportunities based on his personal profile.
One of his biggest concerns was cost.
So I asked him a simple question:
Have you checked your eligibility and optimized your profile pathway using the OASIS eligibility tool that the majority of community members use before starting?
He hadn’t.
He explained that he was comfortable filling out forms and assumed that would be enough.
That’s where most applicants go wrong.
It’s not only about filling out forms correctly.
It’s about understanding what to do before you even begin and aligning your application with what immigration is actually evaluating.
As we reviewed his situation together, it became clear:
- He was taking steps out of order
- He was spending money on things he didn’t actually need
- He was overlooking more efficient pathways to achieve the same outcome
If he had started with a clear understanding of his eligibility and profile strategy, his entire approach would have been different.
After identifying these gaps, he quickly shifted his strategy—not by doing more, but by taking the right steps in the right order using the SkalePLUS Korea Startup Visa Clarity Tool.
