E7-4 Visa Korea: The K-Point System for Transitioning from E-9

The E-7-4 is the visa that changes everything for Vietnamese workers in Korea. It is the bridge between the E-9 temporary labor permit and genuine long-term residency. Workers who earn E-7-4 status can extend indefinitely, bring their spouse and children to live in Korea, and start accumulating the residency history required for F-2 and eventually F-5 permanent residency. Workers who don't understand the system often miss the window — or worse, make choices during their E-9 years that tank their K-Point score.

South Korea overhauled the E-7-4 selection system for 2025-2026 under the "K-Point 1100" framework. If you have been working in Korea on an E-9 visa for four or more years and are thinking about the transition, here is what the system actually requires.

What Makes E-7-4 Different from Other E-7 Subtypes

The E-7 visa has four sub-classifications. E-7-1, E-7-2, and E-7-3 are employer-sponsored professional visas requiring degrees, sector-specific qualifications, or technical certifications. These are the standard professional pathways for university graduates.

E-7-4 is different. It is specifically designed for E-9, E-10, and H-2 visa holders already working in Korea — people who entered as non-professional laborers but have demonstrated, through years of work, language acquisition, and income stability, that they are qualified to stay long-term in a skilled capacity.

The eligibility minimum is four years of legal work experience in Korea under an E-9, E-10, or H-2 visa. But meeting the minimum does not mean you will be selected. The K-Point system ranks all eligible applicants, and annual slot allocations are limited by sector and region. Strategy matters.

The K-Point Scoring Breakdown

Applicants are scored across three main categories, with a maximum of 300 total points. The minimum threshold for consideration is 200 points.

Average Annual Income — up to 120 points

Income is the highest-weighted category but requires careful management. Korean tax authorities track reported income through the employer's salary records. Workers who receive unreported overtime or "cash" payments outside the official payroll do not get credit for those amounts in the K-Point calculation. To maximize this category, all income must be run through official payroll.

The scoring curve: above 25 million KRW annually earns 50 points; above 50 million KRW earns the maximum 120 points. Most E-9 workers in manufacturing earn between 25 and 40 million KRW annually when overtime is included — placing them in the 50–90 point range.

Korean Language Proficiency — up to 120 points

TOPIK 2 earns 50 points. TOPIK 4 or KIIP Level 4 earns the maximum 120 points. This is the single highest-ROI investment a worker can make during their E-9 years. The difference between TOPIK 2 and TOPIK 4 is 70 points — an enormous gap that can determine whether you clear the 200-point floor or not.

Many Vietnamese workers delay language study because the E-9 factory environment requires only basic Korean. This is the most common strategic error. Workers who start KIIP (Korea Immigration and Integration Program) in their first or second year are significantly better positioned than those who start after year three.

Age — up to 60 points

The peak age window is 27–33 years, earning the maximum 60 points. Points taper above and below this range. A worker who arrives at 23 on an E-9 visa and does not actively pursue E-7-4 until age 31 is still in a strong position. A worker who arrives at 32 and waits until 37 to apply has already dropped to a lower tier.

This creates a genuine strategic tension. The four-year minimum puts workers at age 27 or older before they can even apply. Plan around your age bracket early.

Bonus Points: Where the Competition Is Won

Base points (income, language, age) determine whether you are competitive. Bonus points determine whether you succeed. These categories are often overlooked.

Employer recommendation — 50 points (mandatory). You cannot apply for E-7-4 without a letter of support from your current employer. This is not optional or bureaucratic — it is the mechanism that forces a productive relationship with your employer. Workers who have changed jobs frequently or have a poor relationship with their employer often find this step is the bottleneck. Maintaining one employer for an extended period is strategically valuable.

Continuous service at same employer — 20 points. Working for the same employer for more than three years earns 20 bonus points. This directly conflicts with the desire to switch employers for higher wages. Run the numbers: 20 points may be worth more than the wage difference.

Regional employment in depopulation zones — 20 points. South Korea designates 107 areas as "Depopulation Areas" (지방 소멸 위험 지역). Working in one of these rural industrial zones earns 20 bonus points and also opens the F-2-R regional residency pathway. Many Vietnamese workers avoid these areas because of isolation. This is a calculation error. For workers already in their third or fourth year, transferring to a regional employer can be the difference between clearing 200 points or not.

Professional credentials — 20 points. A Korean university degree or national technical certification (기능사 level or above) adds 20 points. For workers with time in their E-9 period, taking a national trade exam in welding, electrical work, or machinery operation is achievable and strategically valuable.

Korean driver's license — 10 points. Simple, achievable, and overlooked by most applicants.

The Timeline: When to Start Planning

The K-Point application window typically opens once per year. Applications must be submitted when the annual quota cycle opens, with results announced in batches. Missing the submission window means waiting another full year.

Most Vietnamese workers on E-9 visas should begin actively planning for E-7-4 no later than their third year of work. This is when the age calculation is still favorable, KIIP enrollment is still achievable at higher levels, and the employer relationship has time to be cultivated for the recommendation letter.

The F-2-R regional visa, introduced in 2025, creates an additional pathway. E-9/E-10 holders who have worked at least two years can transition to E-7-4R (the regional variant) and then to F-2-R after three years in a designated region. The F-2-R requirement includes TOPIK Level 4 proficiency and income at least 70% of the previous year's GNI. This path is slower but may be viable for workers in depopulation zones.

What Comes After E-7-4

E-7-4 holders can bring their spouse and children to Korea (spouses can work in manufacturing and agriculture under the F-2-R framework in regional areas). The E-7-4 visa can be extended indefinitely as long as employment continues.

After accumulating sufficient residency time under E-7-4, workers can apply for F-2 long-term residency and eventually F-5 permanent residency. The specific timelines depend on the residency sub-route, income levels, language certification, and KIIP completion.

One often-missed benefit: the Social Security Agreement between Vietnam and Korea, effective from 2024, allows workers to "totalize" pension contribution periods in both countries. Vietnamese workers leaving Korea are also entitled to a lump-sum refund of their National Pension contributions — a sum that can reach several thousand dollars but is frequently unclaimed.

If you entered Korea as a professional on an E-7-1 visa and are planning your residency transition toward F-2, the framework differs from the K-Point system. The Vietnam to Korea E-7 Work Visa Guide covers the full E-7 professional pathway — from initial application in Vietnam through credential verification and eventual long-term residency — with the specific documents, timelines, and checkpoints that apply to the professional track.

For E-9 workers targeting E-7-4, the strategic lesson is the same as for professionals: the time to start planning is always earlier than you think. The K-Point system rewards preparation, not last-minute applications.
