OASIS Startup Visa Lecture Review — D-8, D-9, or D-10: Which Visa Fits Your Business in Korea?

Hello, this is Administrative Agent Jean.
Following my lecture in May, I gave another OASIS startup visa lecture on June 27 at the Korea Institute of Startup & Entrepreneurship Development in Yeoksam-dong for foreign entrepreneurs preparing to build businesses in Korea.
The central question of the lecture was simple:
What should a foreign founder know in order to start a business in Korea, obtain the right visa, and survive the first renewal?
For foreign entrepreneurs, a visa is not just an entry document.
It affects whether you can start a business, whether you should establish a corporation or register as a sole proprietor, how much investment may be needed, what documents must be kept for renewal, and whether the business structure matches your actual activities.
So this lecture was not designed as a simple document checklist.
Instead, I structured it around a fictional foreign founder named Alex, who moves through realistic situations that foreign entrepreneurs may face while preparing a business in Korea.
What Changed from the Previous Lecture?
The overall structure was similar to the previous session.
Alex, the foreign entrepreneur, prepares a business in Korea, chooses a visa route, and then plans for renewal.
But this time, I added one important visa category:
D-9-4, the visa route often reviewed for foreign sole proprietors.
In the previous lecture, the section that received the strongest response was the comparison of different startup and investment visa routes by business type. So this time, I expanded the discussion beyond D-8-4 technology startup and D-10-2 startup preparation to include D-9-4 for foreign entrepreneurs considering a sole proprietorship structure.
For many foreign entrepreneurs, the word “startup visa” sounds like one single answer.
In reality, the correct visa depends on the structure of the business.
| Business Structure | Visa Route to Review First | | --- | --- | | Technology-based corporate startup | D-8-4 | | Technology startup preparation stage | D-10-2 | | Trade-based business | D-9-1 | | Sole proprietor commercial business | D-9-4 or related route | | Already holding F-2, F-5, or F-6 | Check permitted activity scope before changing status | | Preparing business under short-term stay | Review whether status change is possible |
The key is not simply “I want to start a business.”
The key is how the business will actually operate.
Corporation or sole proprietorship, technology startup or trade business, investment source, current status in Korea, and actual business activities all change the visa strategy.
How Did the Audience Respond?
The strongest response came from the section comparing startup and investment visas by activity type.
When the slide showed which visa might apply to each business model, many participants took photos.
For foreign founders, the hardest part is not memorizing visa names.
The real question is:
Which visa fits my business?
For example:
| Situation | Possible Review Direction | | --- | --- | | Developing an AI-based service | D-8-4 technology startup visa | | Preparing a business before incorporation | D-10-2 startup preparation visa | | Importing or exporting Korean products | D-9-1 trade management visa | | Running a shop or service as a sole proprietor | D-9-4 or related sole proprietor route | | Already holding F-2 or F-6 | Check whether a visa change is necessary | | Working as an interpreter for a company | E-7 or another employment visa route |
A visa is not decided by the business idea alone.
It must be reviewed together with business structure, current status, funding source, incorporation status, and actual activity in Korea.
The Legal Professional Overview Was Also Well Received
The second section that received strong interest was the explanation of legal and administrative professionals in Korea.
For foreign entrepreneurs, Korea’s professional system can be unfamiliar.
In particular, administrative agents and judicial scriveners are not common concepts in many Western countries. So I explained when each professional may be useful.
| Professional | Main Area of Support | | --- | --- | | Attorney | Contracts, disputes, litigation, legal opinions | | Tax accountant | VAT, income tax, corporate tax, tax filing | | Customs broker | Import/export, customs clearance, tariffs | | Patent attorney | Patents, trademarks, designs, intellectual property | | Labor attorney | Employment contracts, wages, dismissal, social insurance | | Judicial scrivener | Registration and certain court or registry matters | | Administrative agent | Visas, permits, immigration documents, administrative appeals support |
AI can now provide a lot of information.
But many foreign founders at the lecture still said the same thing:
“I can search online, but I want to ask someone about my exact situation.”
That sentence captures the real value of this lecture.
Visa information can be searched.
But choosing the right visa for a specific situation still requires human judgment.
Questions from the Lecture
This session had more specific and sharper questions than the previous one.
Some examples included:
- Why did you separate D-9-4 as an individual business route?
- I want to work as an interpreter. Which visa should I consider?
- If I establish a corporation, can I immediately apply for D-8?
- Will establishing a nonprofit corporation affect my visa?
- If my business has started but sales are still low, can I renew my visa?
- Is an AI-generated document checklist enough?
These questions showed me something important.
Foreign entrepreneurs in Korea are not only saying, “I want to start a business.”
They are already thinking about business models, current status, investment structure, renewal risk, and long-term residence.
That level of practical interest is growing.
Some Participants Said the Lecture Was Difficult
There was also honest feedback.
Some participants said the lecture was difficult.
Although I designed the session in a game-like format, the actual content included administrative precedents, visa renewal, administrative disposition, nonprofit corporations, expert selection, and status change strategy.
For foreign founders, that may have felt dense.
So for future lectures, I am considering two versions:
| Version | Focus | | --- | --- | | Beginner version | Visa types, basic flow, business-type comparison | | Practical version | Renewal, supplement requests, administrative discretion, appeals, corporation vs. sole proprietorship |
Visa topics become difficult if we go too deep too quickly.
But if we explain them too simply, they may not help when the actual application begins.
Finding that balance is my next task.
What Will Change in the Next Lecture?
In the next lecture, I plan to focus more directly on visa practice.
Previously, I included related topics such as nonprofit corporations, administrative appeals, and precedents that may indirectly affect visa outcomes. Going forward, I want to make the lecture more useful for foreign founders by focusing on visa selection and comparative strategy.
AI is now quite good at listing required documents.
But the following question still requires human judgment:
“Which visa is better for my situation?”
Let’s take the example of a foreigner who wants to work as an interpreter.
| Situation | Possible Direction | | --- | --- | | Working as an interpreter for a company | E-7 employment visa | | Establishing an interpretation agency as a corporation | D-8-related route | | Operating as a sole proprietor | D-9-related route may be reviewed | | Already holding F-2, F-5, or F-6 | Check permitted activity scope rather than changing status | | Preparing under short-term stay | Review status change possibility and preparation stage |
The same word “interpretation” can lead to different visa routes depending on whether the person is employed, starting a company, working as a sole proprietor, or already holding a residence-type visa.
That is why visa consultation is not just information delivery.
It is closer to situation diagnosis.
I Also Want to Discuss Administrative Uncertainty
The hardest questions during the lecture were vague but important questions like this:
“I want to establish a nonprofit corporation. What should I do?”
This is a very important question, but it cannot be answered properly in one sentence.
A nonprofit corporation must be reviewed based on purpose, activity scope, competent authority, funding structure, directors, business plan, public interest, and relationship with the founder’s status of stay.
When I answered, “It depends on the activity scope, purpose, and funding structure,” the participant looked understandably uncertain.
But this is how administrative practice often works.
To judge whether something is possible, we need to see the documents.
The law gives principles, the administration has discretion, and the applicant needs evidence to bridge the gap.
In future lectures, I want to explain how to reduce that uncertainty.
For example:
- How to use information disclosure requests to understand standards or precedents
- How to respond to supplement requests from administrative agencies
- How to consider administrative appeals after denial or adverse disposition
- How to structure business plans and activity plans for administrative review
- How to make visa purpose and actual activity consistent in documents
Foreign founders do not only need someone to say “possible” or “impossible.”
They need to know what evidence must be reviewed before that answer can be given.
Reducing the Information Gap
In early July, The Hankyoreh reported on migrant workers facing high costs and information gaps in job placement and visa change processes.
That article stayed with me.
A visa is the first gate into Korea: entering, staying, working, and doing business.
But at that gate, many foreign nationals face language barriers, lack of information, time pressure, and uncertainty about fees.
As an administrative agent, I do not think this is a small issue.
Accurate information reduces unnecessary cost.
Clear explanation reduces anxiety.
Proper consultation reduces avoidable mistakes.
My lectures cannot solve every problem. But I hope they can at least help someone understand what they need to check first.
What Foreign Entrepreneurs Should Organize Before Consultation
As I emphasized during the lecture, visa review begins with facts, not a document checklist.
Before consultation, it is helpful to organize the following:
| Category | What to Prepare | | --- | --- | | Current status | D-2, D-10, C-3, F-2, F-6, etc. | | Stay period | Expiration date, extension possibility, planned departure | | Business structure | Corporation, sole proprietorship, trade business, technology startup, nonprofit corporation | | Business stage | Idea stage, preparation stage, business registration completed, corporation established | | Funding structure | Investment, overseas remittance, sales, government support | | Activity in Korea | What you will actually do in Korea | | Hiring plan | Whether you will work alone or hire employees | | Intellectual property | Patent, utility model, design, trademark, copyright, etc. | | OASIS completion | Completed courses, points, certificates | | Long-term goal | D-8, D-9, F-2, F-5, etc. |
With this information, the review becomes much more realistic.
A visa should not be chosen by name.
It should be chosen by structure.
How an Administrative Agent Can Help
Ethos Administrative Office can assist foreign founders and prospective entrepreneurs with:
- Reviewing D-8-4 technology startup visa possibility
- Preparing D-10-2 startup preparation visa strategy
- Reviewing D-9-1 trade management visa options
- Reviewing D-9-4 sole proprietor business visa options
- Checking status change possibility from the current visa
- Organizing OASIS points and certificates
- Reviewing visa strategy before corporation or sole proprietorship setup
- Structuring business plans and activity plans
- Preparing records for first visa renewal
- Identifying weak points that may trigger supplement requests or denial
For foreign startup visas, the first approval matters.
But building a structure that can survive renewal matters even more.
Sales, contracts, taxes, office records, intellectual property, and business progress materials should be managed from the beginning.
Closing
The June 27 OASIS lecture was meaningful for me as well.
It reminded me how seriously foreign founders are thinking about building businesses in Korea, and how many questions they still have when facing visa and administrative procedures.
That is why I added D-9-4 to this lecture.
Foreign entrepreneurs do not all build the same kind of business.
Therefore, their visa routes cannot be reduced to one answer.
D-8-4, D-10-2, D-9-1, D-9-4, E-7, F-2, F-6.
The important thing is not knowing many visa names.
The important thing is knowing which option is realistic for your exact situation.
In the next lecture, I plan to cover visa selection, administrative discretion, information disclosure requests, and administrative appeals in a more practical way.
I hope to continue making lectures that help foreign entrepreneurs in Korea avoid unnecessary detours caused by lack of information.
