F-5-5 Permanent Residency Korea: Document Checklist for Foreign Investors [2026]

1. What Is the F-5-5 Route?

The F-5-5 visa is an investment-based permanent residency route available to foreign nationals who have continuously maintained a qualifying investment in Korea through a D-8 (corporate investment) visa. It is one of the most accessible PR pathways for foreign entrepreneurs and investors, as it does not require extensive years of general residence history — the key criteria are the investment amount and business activity.

There are two qualifying thresholds under the F-5-5 route:

• KRW 500M single-investor threshold: The investor must have personally remitted at least KRW 500,000,000 (approximately USD 370,000) directly from overseas into a Korean corporation in their name.
• KRW 300M + 5 Korean national employees: The investor must have remitted at least KRW 300,000,000 from overseas AND continuously maintained a minimum of 5 full-time Korean national employees on the payroll of their Korean company.

In both cases, the investor must be currently holding a D-8 visa at the time of application. The F-5-5 route is one of the fastest routes to PR in Korea, but unlike some other PR routes, it does not waive the Korean language requirement entirely — a minimum TOPIK Level 1 score is required (a relatively low bar). The business must remain active at the time of application, and no dormant or shell companies are permitted.

2. Eligibility Requirements — At a Glance

The table below summarizes the core eligibility criteria for F-5-5. All conditions must be met simultaneously at the time of application.

3. Core Document Checklist

The following documents are required for all F-5-5 applications. Additional documents may be requested by the immigration office based on individual circumstances. All foreign-language documents must be accompanied by an official Korean translation.

4. Investment Capital Proof in Detail (외국환매입증명서)

The foreign currency exchange certificate (외국환매입증명서) is the single most important document in an F-5-5 application. It is issued by the Korean bank that received the wire transfer and certifies that the funds originated from overseas. Without valid certificates totaling the required threshold, the application will be rejected.

How the Certificate Works

Each international wire transfer of investment funds into a Korean company account generates one foreign currency exchange certificate from the receiving bank. If the investment was made in multiple tranches (e.g., KRW 200M then KRW 300M), each transfer produces a separate certificate. You must collect all certificates and verify that the cumulative total meets the KRW 500M (or KRW 300M) threshold.

Critical Rules

• Capital must be in the company's name, not a personal account. Funds remitted to an individual's personal bank account and later transferred to the company do not qualify as direct foreign investment.
• Retained earnings do not count. Profits reinvested from Korean business operations are not overseas remittances and cannot be included in the investment total.
• Domestic loans do not count. Borrowing from a Korean bank or investor to fund the company does not constitute overseas remittance, regardless of the amount.
• Capital must remain in the company. If original investment capital has been withdrawn or distributed as dividends below the threshold, the remaining capital may be insufficient. Additional overseas remittance is required to restore the threshold before applying.
• Currency conversion. The threshold is calculated in KRW at the time of each remittance. If the KRW value at the time of transfer was below threshold, subsequent remittances must make up the difference.

5. Employee Documentation for the 300M+5 Route

If you are applying via Route B (KRW 300M + 5 Korean national employees), employee documentation is as critical as the capital proof. The following rules govern this requirement.

Who Counts as a Qualifying Employee?

Only Korean national (대한민국 국민) employees count toward the 5-employee threshold. Foreign national employees, including other visa holders working at your company, do not satisfy this requirement regardless of their employment status or time with the company.

Required Employee Documents

• NHIS 사업장 취득자 명세서: Issued by the National Health Insurance Corporation; must list all 5 qualifying Korean employees currently enrolled at your business workplace. This is the primary verification document used by immigration officers.
• Employment contracts: Individual employment contracts for each of the 5 Korean national employees, showing full-time status and current employment dates.
• Employee resident registration numbers: The resident registration numbers on the employment contracts and NHIS enrollment records must match exactly. Discrepancies will delay processing.

Maintaining the 5-Employee Count

The 5-employee threshold must be maintained continuously throughout the application period. Specific risks to be aware of:

• If an employee resigns and headcount drops below 5 before PR approval, the application is likely to be rejected or suspended. Replacement hiring must be completed and documented before submission or resubmission.
• Part-time employees do not count — all 5 must be full-time (40 hours/week or as defined under Korean labor law).
• After F-5-5 is approved and granted, the 5-employee requirement no longer applies to maintain PR status — it is only a condition for obtaining PR, not for retaining it.

6. Korean Language Requirement for F-5-5

Unlike some other long-term residency categories where no Korean language is required at all, the F-5-5 route does require a minimum level of Korean language ability. However, the bar is set significantly lower than for general F-5 routes.

Accepted Language Certificates

• TOPIK Level 1 (한국어능력시험 1급): The minimum accepted score. TOPIK Level 1 represents basic conversational ability and is the most straightforward path to satisfying the requirement. The certificate must be valid — issued within 2 years of the application date.
• Social Integration Program (사회통합프로그램) partial completion: Completion of certain stages of the Social Integration Program may be accepted in lieu of TOPIK. Confirm with your immigration office whether your stage level is sufficient.

What If You Have No Korean Ability?

The language requirement cannot be entirely waived for F-5-5. If you have not yet taken TOPIK, you must register for the next available TOPIK session (offered multiple times per year by the National Institute for International Education) and obtain at least Level 1 before submitting your F-5-5 application. An interpreter may be arranged for the immigration interview, but a valid language certificate is still required in the document package.
