Overview
When you are thinking of handing a D-8 application or extension to an administrative agent, a service brochure alone gives you little to compare. This article turns the decision into questions about what the agent actually handles, which documents you prepare yourself, how the process is divided into steps, and how far in-person attendance and representation go, rather than about price or outcomes.
Approval is decided by examination. An explanation that promises a result in advance therefore gives you nothing to check against. This article contains no prices, no processing times and no ranking of offices. The D-8 scope of Vision Administrative Office (VISAS KOREA) is document preparation and guidance on the submission steps, and the questions below can be used the same way with any office you contact. Checking denial criteria and the extension document list are covered in separate articles.
At a Glance
| Item | Detail |
|---|---|
| Scope | Questions to check before handing a D-8 application or extension to an agent (no prices, outcomes or office rankings) |
| Decide first | Which sub-code applies (D-8-1, D-8-2, D-8-3 or D-8-4) and whether this is a change from your current status or a visa route |
| Document basis | Whether the documents you are told to prepare match the required list; the head of the office may add or remove documents |
| Attendance and representation | For stay permits you must be in Korea, and an agency cannot file for a foreigner who is abroad; for a visa issuance certificate filed by a representative, a power of attorney, the representative's employment certificate and ID are added |
| Fees | The government review fee is not refunded once the application is accepted, so confirm it separately from the agent's own fee |
| Wording on results | Approval is decided by examination |
Scope of Activity
- Questions to put to an agent: the scope of work handled for you, the documents you prepare, the steps in the process, and in-person attendance and representation
- For each question, what you should check (for example the D-8-1 extension document list)
- Out of scope: comparing or recommending offices, prices, processing time, and judging the likelihood of approval
Who Qualifies
- Investors and company representatives preparing a new D-8 application and looking for an agent
- People approaching a D-8 extension who are deciding whether to hand over document preparation
- Those who first want to check whether a change from their current status to D-8 is possible
- Prospective investors abroad who are looking at setting up a Korean company and a visa application together
Required Documents
- Sub-code and route: decide which type applies, D-8-1 (investment in a corporation), D-8-2 (venture investment), D-8-3 (investment in an individual enterprise) or D-8-4 (technology startup), and whether this is a change from your current status or a visa issuance certificate route
- Basic documents (D-8-1 extension list): application form (Form No. 34), passport and ARC, one standard photo, copy of business registration certificate, corporate registry certificate, original statement of changes in shareholders, copy of the investment company registration certificate
- Proof of bringing in investment funds: for those it applies to, the foreign-exchange export permit or report from customs or a bank in the home country, and a statement of how the funds were brought in such as a remittance confirmation, foreign-currency purchase certificate or customs declaration. Funds are in principle in the investor's own name
- Business, workplace and residence proof: a business performance certificate such as export-import records, proof that the workplace exists (office lease, photos of the premises, office space and signboard), and proof of residence such as a lease
- Extra documents for individual investors under KRW 300 million: proof of how the capital was used (purchase receipts, office fit-out costs, domestic bank account statements) and, when needed, documents from the home country on business experience in the field
- Document format: documents issued abroad need an Apostille or consular confirmation; documents issued in Korea without a stated validity must be within 3 months of issue
- Attendance and representation: stay permits are filed while in Korea; ask in writing at which steps a representative may file and what authorization documents are added
Application Process
- Check eligibility — confirm your current status, career, degree and contract type match the requirements.
- Prepare documents — foreign public documents need a translator's certification plus an apostille (or consular confirmation for non-member states).
- Book a visit — reserve a slot at your Immigration Office via HiKorea (www.hikorea.go.kr), or file online where e-Application is available.
- File and pay — submit the Integrated Application Form (Form No. 34) and pay the screening fee.
- Review — respond to any request for supplementary documents within the deadline.
- Result — on approval, the period of stay and status are granted; reissue your ARC if required.
Key Points
- Stay permit applications must be filed while you are in Korea, leaving after filing may lead to denial, and an immigration-service agency cannot file for a foreigner who is abroad. If you have travel plans, tell the agent before handing the case over and plan the schedule together.
- The government review fee is not refunded once the application is accepted. It is separate from what you pay the agent, so ask for it in writing which item belongs to which side. This article does not cover amounts.
- The head of the Immigration Office may add or remove documents when particularly needed for examination. If an explanation treats the document list as fixed or promises an approval, ask what it is based on.
- A translation of a foreign-language document must be written by someone other than the applicant, and under the Administrative Agents Act only a foreign-language translation administrative agent may, as a business and for a fee at the client's request, translate documents related to administrative agency work. Check this if you are handing over translation too.
- Denial reasons and fixes are covered in the D-8 denial article, and the full extension document list in the D-8 extension documents article. This article is limited to the questions to ask before choosing an office.
- Documents issued in Korea must normally be dated within 3 months unless another validity period applies.
- Documents already on file in your alien registration record need not be resubmitted.
- Health certificates, drug test results and pre-employment medical reports must be submitted sealed by the issuing hospital (do not open).
- You must be in Korea when applying; leaving the country after filing may result in refusal.
- Screening fees are non-refundable once the application is accepted.
- The head of the Immigration Office may add or waive documents where necessary for review.
