Korean E-7 Visa AtoZ for HR ② JD Design

E-7 (Specialty Occupation) is one of the most common work-based statuses used in global hiring in Korea. In practice, cases slow down not because the steps are complicated, but because the early direction is unclear. If the occupation code and job scope are set incorrectly at the start, the process often turns into repeated supplementation. This can happen even when the rest of the documents are prepared carefully.

Two decisions matter most at the beginning:

• Which E-7 occupation code to apply under
• How to design the JD so it clearly fits that occupation’s defined scope

E-7 reviews move smoothly when the company’s actual business, the job’s real duties and outputs, the candidate’s relevant background, and the selected occupation code form a single coherent story. If this linkage is weak, improving JD wording alone rarely resolves the issue. Instead, delays and additional requests become structural.

What this article helps you produce

By the end of this article, HR should be able to:

1. Narrow down 1 to 3 realistic occupation code candidates for the role
2. Understand when a “similar occupation” approach may be acceptable, and what risks it creates (including differences in approval route)
3. Draft an E-7-ready JD that is defensible under review standards

Key takeaways

• E-7 review does not evaluate your internal job title as-is. It assesses the role after translating it into the defined scope of an eligible occupation code. This is why the occupation code becomes the starting point of JD design.
• If the link between business, job outputs, candidate relevance, and occupation code is weak, supplementation tends to repeat. This is a structural issue, not a wording issue.
• When an exact match is difficult, you may consider a similar occupation approach. However, review route and strictness can differ depending on whether the occupation falls under KSCO major groups 1–2 versus 3–8.
• Occupation-specific criteria may add additional gates, such as employer requirements, candidate requirements, salary thresholds, recommendation letters, quotas, operational restrictions, or domestic employment protection review. Checking these early can reduce timeline risk significantly.
• An E-7 JD should be written in the language of occupation descriptions and eligible job examples, not in the language of internal titles. A controlled scope works best. A practical structure is 5 to 8 core responsibilities supported by 3 concrete deliverables.

Why occupation codes and the JD must be designed together

E-7 applies to foreign nationals who will engage in activities designated by the Minister of Justice under a contract with a Korean entity. This means the review does not accept a company job posting at face value. Instead, it evaluates whether:

• The company’s actual business and operations justify the role
• The role’s duties and outputs fall within the scope of an eligible occupation code
• The candidate’s background is relevant to performing that role and can be substantiated

Because this is how the review is structured, occupation code selection defines what the JD must prove.

The core concept: “relevance” across four connected elements

In practical terms, four elements must align:

1. The company’s actual business (what it truly sells and delivers)
2. The job’s real scope and outputs (what the role produces)
3. The selected E-7 occupation code (its officially defined scope)
4. The candidate’s relevant background (education and experience)

When these four elements reinforce each other, E-7 documentation becomes much easier to defend. When they conflict, the case often becomes fragile regardless of how polished the JD looks.

Understanding the occupation code framework and similar occupation logic

E-7 eligible occupations are operated as “introduced occupations” based on KSCO classification and policy criteria. The review typically asks:

1. Is the role within the eligible occupation list
2. Does it meet the occupation’s detailed criteria (scope, employer requirements, candidate requirements)
3. Can the case be proven through documents

Many real-world roles do not match an occupation perfectly. In such cases, it may be possible to apply under a similar occupation if the overall logic is reasonable. However, approval authority and review strictness may differ depending on KSCO major group classification. This matters operationally. It should be treated as an early risk factor, not a late-stage surprise.

JD design principles for E-7

An E-7 JD is not a branding document. It is a review document. It must make occupation fit and hiring necessity legible to a reviewer.

Practical principles:

• Prefer clarity over marketing language
• Define scope through responsibilities and deliverables
• Avoid mixing unrelated duties that could blur occupation fit
• Align JD verbs and duty categories with the occupation’s official description and examples
• Keep qualifications consistent with general E-7 eligibility logic to preserve relevance

A controlled JD scope reduces review ambiguity. In many cases, limiting the JD to 5–8 core responsibilities and 3 deliverables provides the cleanest structure.

Examples of where occupation codes diverge in high-frequency roles

IT and software roles are not well captured by the single word “developer.” The eligible list separates system software, application software, web development, data roles, and security roles. A JD should make the build target and responsibility scope explicit. It should show design and development ownership rather than reading like maintenance-only work.

Mechanical, plant, and robotics roles often fail when a broad “engineer” JD is submitted without specifying the technical domain, project phase, and deliverables. For plant roles, the JD should clarify which phases and which technical areas are covered. For robotics roles, the JD often needs more conservative and specific qualifications.

Overseas sales roles tend to have particularly specific operating requirements. A JD should define target markets, product scope, responsibility across the export or contract process, KPIs, and work mode.
