Korea D-7 Visa: One-Year Overseas Employment Rule and Required Documents

The overseas headquarters has established a branch or liaison office in Korea, and you have been selected to manage operations, transfer technical knowledge or perform another specialized role.

Then HR notices an important condition in Korea’s D-7 visa rules:

The employee generally must have worked for the overseas organization for at least one year.

Does that mean exactly 12 months at the overseas headquarters?

What if you worked at another office of the same foreign company?

Which documents actually prove the employment period?

And is the one-year requirement always mandatory?

Before preparing a D-7 intra-company transfer application, check four things first: the employee’s overseas service period, the relationship between the overseas and Korean entities, the employee’s role in Korea, and the documents that prove the transfer.

Check 1: Have You Worked for the Overseas Organization for at Least One Year?

The basic rule comes from Korea’s Immigration Control Act Enforcement Decree.

The D-7 category covers a person who has worked for at least one year at the headquarters, branch or other business establishment of a foreign public institution, organization or company and is then dispatched to an affiliate, subsidiary, branch or office in Korea as essential professional personnel. D-8 cases are excluded from this D-7 route.

This wording matters.

The rule should not automatically be rewritten as:

“You must have worked exactly 12 consecutive months at the foreign headquarters immediately before departure.”

The statutory language is broader. It refers to at least one year of employment at the foreign organization’s headquarters, branch or other business establishment.

HR should therefore document the applicant’s actual employment history rather than rely only on the date shown on the latest headquarters appointment letter.

If the employee has not accumulated the required period, however, the ordinary D-7 eligibility rule becomes a serious issue unless a recognized exception applies.

Check 2: Is the Korean Destination Connected to the Overseas Organization?

One year of overseas employment is only part of the test.

The employee must also be dispatched to a qualifying organization in Korea.

The Enforcement Decree refers to an affiliate, subsidiary, branch or office in Korea. This means the D-7 structure requires a real organizational connection between the overseas sender and the Korean receiving entity.

For a standard foreign-company D-7 application, official immigration materials list supporting documents such as an overseas-company employment certificate, a personnel or dispatch order, documents proving establishment of the Korean branch or office, and evidence relating to operating funds or the business plan.

This is why establishing an unrelated Korean company and simply calling the employee an “intra-company transferee” does not satisfy the basic structure of D-7.

The corporate relationship must make sense on paper.

Check 3: Is the Employee Essential Professional Personnel?

D-7 is not a general visa for every employee a foreign company wants to relocate to Korea.

The law requires the transferee to be dispatched as essential professional personnel.

That makes the employee’s actual function important.

A senior-sounding title alone does not establish eligibility. At the same time, the public rule should not be reduced to an invented list of acceptable job titles.

The application should instead make clear what the employee actually does, what experience or expertise the employee brings, and why that person is being transferred to the Korean operation.

Official consular guidance for relevant D-7 cases also lists materials such as a résumé or career certificate as evidence that the applicant is essential professional personnel.

The documents should tell one consistent story:

This person already works within the overseas organization, has a qualifying professional function, and is being transferred to perform that function in Korea.

Check 4: What Documents Prove the One-Year Employment Period?

This is where many online D-7 checklists become too rigid.

You may see claims that every applicant must submit:

12 months of salary bank statements, 12 months of payslips, a home-country income-tax certificate and social-insurance records.

Those records can certainly help in a particular case.

But the official D-7 materials reviewed for this article do not establish that exact package as a universal statutory requirement for every applicant.

For the standard foreign-company D-7 route, the official document list includes an overseas-company employment certificate and a personnel or dispatch order, together with documents establishing the Korean operation and relevant operating-fund or business information.

Additional evidence may be requested when the employment history is unclear or requires further verification.

That could make payroll, tax, banking or social-insurance records useful evidence depending on the case.

But “useful additional evidence” is not the same as “a mandatory 12-month document package for every D-7 applicant.”

The practical objective is to make the qualifying overseas employment period clear, consistent and verifiable.

What Should the Dispatch Order Show?

The dispatch order connects the employee’s overseas position with the Korean assignment.

Official D-7 guidance expressly includes a personnel or dispatch order among the supporting documents, and consular guidance may require the dispatch period to be stated.

A well-prepared dispatch order should therefore make the transfer understandable: who is being sent, which organization is sending the employee, where the employee will work in Korea, the assignment period, and the employee’s position or duties.

But there is no reason to invent a single worldwide D-7 template if the official rules do not provide one.

The same caution applies to document authentication.

Do not assume that every foreign-issued dispatch order automatically requires an Apostille simply because it was prepared outside Korea.

Authentication requirements can depend on the type of document, country of issuance and place where the visa application is filed.

Check the requirements of the relevant Korean immigration office or diplomatic mission before paying for legalization.

Is the One-Year Employment Rule Absolute?

No.

The Enforcement Decree itself provides exceptions.

The one-year requirement does not apply in certain cases involving national key industries or national projects, or in other cases where the Minister of Justice recognizes the need.

Official Korean consular guidance also identifies a practical exception involving essential professional personnel dispatched to a Korean branch of a foreign company with at least USD 500,000 in operating-fund introduction performance.

The important point is not the USD 500,000 figure itself.

It is that the one-year rule has recognized exceptions, but a newly established foreign company does not automatically receive an exemption simply because it is new.

If the proposed transferee has less than one year of qualifying overseas employment, the company should identify the specific legal or administrative basis for an exception before proceeding.

Do Not Treat USD 500,000 as a General D-7 Capital Requirement

The USD 500,000 figure can easily be misunderstood.

It does not mean that every foreign company seeking a D-7 visa must invest or remit USD 500,000.

D-7 contains different transfer structures, and USD 500,000 appears in different contexts within those rules.

For example, the Enforcement Decree separately addresses employees who worked at an overseas subsidiary or branch established by a Korean listed corporation or public institution and are then dispatched to the Korean headquarters. A USD 500,000 threshold appears in that separate structure as well.

Do not mix these provisions together.

Before applying any dollar threshold, first identify the direction of the transfer and the specific D-7 category involved.

What Should HR Prepare First?

Do not begin by collecting twelve months of bank statements or obtaining Apostilles for every foreign document.

Begin with eligibility.

First, map the relationship between the overseas employer and the Korean affiliate, subsidiary, branch or office.

Second, confirm and document the employee’s qualifying overseas service period.

Third, define the employee’s professional role and why the Korean assignment fits the D-7 intra-company transfer structure.

Fourth, prepare the core evidence: the overseas employment certificate, personnel or dispatch order, Korean branch or office establishment documents, and applicable operating-fund or business documents.

Then check the specific filing location for additional documents, authentication requirements and procedural details.

This order can prevent a company from spending time and money preparing documents before discovering that the employee does not meet the underlying D-7 eligibility requirements.

The Key Point

The Korea D-7 visa is not simply a visa for anyone employed by a foreign company.

For the standard foreign-company intra-company transfer route, the applicant generally needs at least one year of employment at the foreign organization’s headquarters, branch or other business establishment and must be dispatched to a qualifying Korean affiliate, subsidiary, branch or office as essential professional personnel.

The one-year rule is real.

But it should not be expanded into requirements that the official rules do not universally impose.

The official materials reviewed for this article do not establish one mandatory package of exactly 12 monthly bank statements, a specific home-country tax certificate and an Apostilled dispatch order for every D-7 applicant.

The one-year requirement also has recognized exceptions.

So before preparing the documents, answer four questions:

Has the employee completed the qualifying overseas service period?

Is there a qualifying relationship between the overseas sender and Korean receiving entity?

Is the employee being transferred as essential professional personnel?

Can the company document those facts consistently?

If those four pieces fit together, the paperwork has a clear purpose.

If they do not, collecting more documents will not fix the underlying D-7 eligibility problem.
