Korea E-7 Visa Occupation Codes: Complete 87 Job Categories Explained (2026 Update)

Your job title means nothing to Korean Immigration. A “Marketing Manager” who builds campaign strategies belongs to a different occupation code than a “Marketing Manager” who spends 80% of their day creating SNS content. Most E-7 applicants pick their code based on title alone—and that’s exactly why code mismatch remains the number one rejection trigger in 2026. Immigration officers don’t read your LinkedIn profile; they compare your actual daily duties against the official code definition in the Korean Standard Occupational Classification system. If those don’t align, your application gets flagged before anyone even looks at your qualifications.

The E-7 visa system uses exactly 87 designated occupation codes spread across subcategories E-7-1 through E-7-4 and E-7-S. Each code carries specific eligibility requirements: minimum salary thresholds, required qualifications, and detailed duty descriptions that must match your employment contract and 고용사유서 (goyong sayuseo, or “statement of employment reasons”). Wrong code, rejected application. In some cases, your employer faces penalties for misrepresentation.

How the E-7 Occupation Code System Works

The E-7 visa isn’t a single category—it’s a framework containing multiple subcategories, each tied to specific occupation codes defined by the Korean Standard Occupational Classification (KSOC) system. As of April 2026, the Ministry of Justice recognizes 87 designated occupation codes across all E-7 subcategories, according to the official HiKorea portal.

The Five E-7 Subcategories

Each subcategory has different salary thresholds, qualification requirements, and eligible occupation codes. Understanding which subcategory your role falls under determines your entire application strategy.

Here’s the critical distinction: E-7-1 codes are for professional roles requiring university degrees or equivalent experience, while E-7-2 codes cover semi-professional positions in specific industries like hospitality, tourism, and healthcare support. Applying under the wrong subcategory is one of the fastest ways to get rejected. For a detailed comparison of qualification requirements across subcategories, see our E-7-1 vs E-7-2 vs E-7-3 vs E-7-4 comparison guide.

How Codes Map to the Korean Standard Occupational Classification

Each E-7 occupation code corresponds to a specific KSOC code (한국표준직업분류, or “Korean Standard Occupational Classification” in Korean). When you apply through HiKorea, you select from the approved list—not the broader KSOC system. The Ministry of Justice maintains a curated subset of occupations eligible for E-7 sponsorship, updated periodically through official notices on moj.go.kr.

Immigration officers verify applications against the official KSOC duty descriptions, not your company’s internal job titles. A ‘Product Manager’ at a tech startup and a ‘Product Manager’ at a manufacturing firm often qualify under entirely different codes.

E-7-1 Professional Occupation Codes (67 Categories)

E-7-1 is the most common subcategory for foreign professionals in Korea, covering 67 occupation codes across technology, engineering, business, creative industries, and specialized sciences. The minimum salary requirement for E-7-1 is typically the previous year’s GNI (Gross National Income) per capita—approximately ₩31M annually as of 2026—though some codes have higher thresholds.

Technology & IT Codes

Engineering Codes

Business & Marketing Codes

Creative & Design Codes

Science & Research Codes

E-7-1 includes additional codes for specialized fields like architecture, pharmaceuticals, legal services (for foreign-qualified lawyers), translation/interpretation, and more. The complete official list is available on the HiKorea portal under visa application forms.

E-7-2 Semi-Professional Occupation Codes (9 Categories)

E-7-2 covers semi-professional roles in specific industries—primarily hospitality, tourism, healthcare support, and customer service. The minimum salary threshold is approximately 80% of GNI per capita (~₩25M annually as of 2026). These codes are industry-specific, meaning you can only apply under E-7-2 if your employer operates in an eligible sector.

E-7-3 and E-7-4 Skilled Worker Codes (10 Categories)

E-7-3 covers general skilled workers in manufacturing and technical trades, while E-7-4 uses a points-based system for skilled trades. These subcategories target technical workers who may not have university degrees but possess verified vocational skills.

E-7-3 General Skilled Worker Codes (7 Categories)

E-7-4 Points-Based Skilled Worker Codes (3 Categories)

E-7-4 is unique because it requires applicants to score a minimum number of points based on Korean language ability (TOPIK, or Test of Proficiency in Korean), technical certifications, age, and prior legal employment in Korea. This subcategory is typically for workers transitioning from E-9 (non-professional employment) visas.

How to Verify Your Code Matches Your Daily Duties

The number one reason for E-7 rejection is code mismatch—and it’s entirely preventable. Immigration officers don’t care what your business card says; they compare your actual daily tasks against the official KSOC duty description for your selected code. Here’s how to verify alignment before you apply.

Step 1: Get the Official Code Definition

Go to hikorea.go.kr → 민원서비스 (Civil Services) → 체류 (Stay) → E-7 → Download the occupation code list (직종 목록, or “job category list”). This document contains the official duty descriptions for each code in Korean. Use a translation tool or ask your company’s Korean staff to translate the exact wording.

 Time required: 15-20 minutes

Step 2: Document Your Actual Daily Tasks

Write out exactly what you do in a typical work week. Be specific:

• What percentage of your time goes to each task?
• What tools, software, or equipment do you use?
• What deliverables do you produce?
• Who do you report to, and what decisions do you make?

Example: “I spend 60% of my time writing Python code for backend APIs, 20% debugging production issues, 15% in code reviews, and 5% in planning meetings.”

Step 3: Compare Against Multiple Codes

Don’t assume your job title matches one code. Many roles could fit multiple codes depending on emphasis:

Step 4: Match 70%+ of Duties

Immigration typically requires that at least 70% of your daily responsibilities match the code’s official description. Split 50/50 between two codes? Pick the one your performance review actually measures.

Step 5: Get Written Confirmation

Before finalizing your application, ask your HR department or supervisor to confirm in writing that your job duties align with the selected code. This documentation can be referenced if immigration requests additional verification.

고용사유서 and Employment Letter Alignment

Your employer’s 고용사유서 (Statement of Employment Reasons) is the single most scrutinized document in your E-7 application. Immigration officers use it to verify that your selected occupation code matches what your company actually hired you to do.

What the 고용사유서 Must Include

According to Ministry of Justice guidelines, a compliant 고용사유서 must contain:

• Specific job duties — not just a job title, but detailed task descriptions
• Why a foreign worker is needed — specialized skills, language abilities, international experience
• How duties align with the selected occupation code — explicit reference to the KSOC code
• Qualifications verification — how the applicant’s background matches the role

Employment Verification Letters Must Include Duties

If you’re including employment verification letters from previous employers (especially overseas), these must also include job duties — not just employment dates and job titles.

For overseas employment verification:

• Request a letter on company letterhead describing your specific responsibilities
• Include the tasks you performed, not just your title
• If the company only provides dates and title, request a separate reference letter from your manager
• For U.S. employers using The Work Number or similar services, you’ll need a supplementary letter — those systems only verify employment, not duties

Letters from overseas may require apostille authentication. The sequence is: Manager signature → Notary Public → State/Country Apostille. For detailed guidance on employment documentation for visa transitions, see our guide on how to get E-7 visa sponsorship.

E-7 Occupation Code Verification Checklist

Use this checklist before submitting your application. Each item represents a potential rejection trigger if not properly addressed.

Real Case: Code Mismatch Rejection

Marcus, 35 — American Marketing Manager in Incheon, E-7-1

The trap Marcus fell into: His employer copied the job posting into the 고용사유서 — which described the ideal candidate, not what Marcus actually did. Code 2733 (Marketing Specialist) requires duties focused on market research, strategy development, and brand positioning. Marcus spent 80% of his time creating Instagram and TikTok content, editing videos, and managing influencer partnerships. Immigration flagged the mismatch during document review.

The fix: The company resubmitted under code 2871 (Multimedia Producer) with a revised 고용사유서 that accurately described content production as Marcus’s primary function. Approved in 5 weeks.

The lesson: Document your actual daily duties before your employer writes the 고용사유서. The code must match what you do — not your title, not the job posting, not what sounds most impressive.

Frequently Asked Questions

Can I change my occupation code after my E-7 visa is approved?

Changing your occupation code requires a new application and updated documentation, including a revised 고용사유서 (employment reason statement) from your employer. If your actual duties shift significantly—say, from development to management—you should update your code at your next renewal. Working under a mismatched code will surface at renewal or F-2-7 transition — and by then it’s harder to fix.

What if my job involves multiple occupation codes equally?

Immigration requires you to select one primary code. Figure out which category accounts for at least 50–70% of your deliverables—what you actually produce and get evaluated on. Your 고용사유서 should acknowledge the role’s breadth while emphasizing alignment with the selected code. Some applicants have successfully used broader codes (like 2711 Business Consultant) for genuinely hybrid strategic roles.

How do I find the official KSOC description for my code?

Download the occupation code list from hikorea.go.kr under the E-7 visa application section. The list includes code numbers, Korean titles, and brief descriptions. For detailed duty breakdowns, check the Korean Statistical Information Service (KOSIS) occupation classification database, though navigating it requires Korean language skills.

My company has never sponsored an E-7 before. Will this hurt my application?

Companies without prior E-7 sponsorship experience often struggle with 고용사유서 formatting and content. Immigration may scrutinize these applications more closely. Ask your HR team to consult the official guidelines on HiKorea or hire an immigration consultant for document review. Large companies with expat experience typically have streamlined processes, while smaller companies may need extra preparation time.

Does my job title need to match the occupation code title exactly?

No. Job titles are company-specific, while occupation codes are government classifications. A “Growth Hacker” at a startup might correctly use code 2733 (Marketing Specialist) or 2222 (Application Developer) depending on whether their primary work involves marketing strategy or technical implementation. What matters is duty alignment, not title alignment.

What happens if immigration discovers a code mismatch after my visa is issued?

If immigration determines your actual work doesn’t match your registered code—often discovered during renewal applications or random employer audits—they may deny your renewal, require you to find new employment under the correct code, or in serious cases, treat it as a violation of your visa conditions. This can affect future visa applications, including F-2-7 and F-5 permanent residency.

Are there occupation codes that are harder to get approved?

Codes in highly competitive or saturated fields (general business administration, non-specialized marketing) face more scrutiny because immigration assesses whether a foreign worker is genuinely necessary. Highly technical codes (AI/ML engineering, semiconductor specialties) or codes requiring specific certifications typically see higher approval rates because domestic talent shortages are easier to demonstrate.

What To Do Next

If you haven’t identified your occupation code yet

Start by documenting your actual daily tasks in detail. Spend one week tracking what you do each day and calculate the percentage breakdown. Then download the official occupation code list from hikorea.go.kr and compare your task list against the KSOC descriptions for two or three candidate codes. Choose the code where 70% or more of your work aligns with the official description.

If you’ve identified your code but haven’t applied yet

Review your employment contract to confirm the job duties section matches your selected code. Share the code’s official KSOC description with your employer before they write the 고용사유서 (goyong sayuseok, or employment reason statement)—this ensures alignment from the start. Verify your salary meets the subcategory minimum (E-7-1: approximately ₩31M, E-7-2: approximately ₩25M) and confirm your employer hasn’t exceeded the foreign worker ratio limit.

If you’re already on an E-7 and concerned about code mismatch

Compare your current daily duties against your registered code’s KSOC description. If significant drift has occurred (meaning your role has changed since you applied), address this before your next renewal. Either adjust your duties to realign with the code or prepare to apply for a code change with updated documentation. Don’t wait until renewal. Fixing it early is far simpler than explaining it later.

If you’re planning to transition to F-2-7

Your E-7 occupation code affects your F-2-7 income bracket scoring. Confirm your taxable income (shown on your 소득금액증명원, or sodeuk geumak jeungmyeongwon, which is your income verification certificate) aligns with the salary documented in your E-7 application. Any discrepancies—like untaxed allowances reducing your certificate amount below expectations—should be understood now, not during your F-2-7 application. Review our income certificate guide for documentation requirements.
