How Korean Employers Sponsor an E-7 Visa — HR Guide to Hiring Foreign Nationals
Korean companies looking to hire foreign talent face a specific set of immigration requirements. The E-7 (Specific Activities) visa is the primary route for skilled foreign workers, but the employer plays a central role in the application — not just as a sponsor, but sometimes as the primary applicant. This guide is written for Korean HR teams, startup founders, and managers who need to understand the full E-7 sponsorship process, including when Ministry pre-approval (고용추천서) is required and how a GOLD CARD employment recommendation can simplify the application for advanced-technology hires.

Filing caution
Requirements can change by nationality, local immigration office, and filing channel. Confirm exact requirements with HiKorea, the responsible Korean consulate, or a licensed immigration specialist before filing.
Is your company eligible to sponsor an E-7?
Not all Korean companies can sponsor E-7 workers. Basic eligibility requirements: ① The company must be a legally registered Korean business (사업자등록증 required) ② The company must have been operating for at least 1 year (some exceptions for startups with qualifying status) ③ The company must not have any immigration law violations on record (unpaid fines, previous illegal workers, etc.) ④ The company must have at least one Korean employee (the ratio of foreign to Korean employees is tracked — a company cannot have only foreign workers without demonstrating it cannot fill the role domestically). The specific worker ratio requirements vary by occupation category and company size. Korean companies with fewer than 20 employees face stricter scrutiny; those with 50+ employees typically have more flexibility.
Which occupations require Ministry pre-approval (고용추천서)?
고용추천서 (employment recommendation letter / Ministry pre-approval) is required for E-7 applications in certain occupation categories to verify that the job meets specific standards and that there is a genuine need that cannot be filled domestically. The relevant Ministry depends on the occupation: Ministry of Employment and Labor (고용노동부) for most professional and management roles, Ministry of Science and ICT (과기부) for IT/technology roles, Ministry of Culture, Sports and Tourism (문체부) for cultural/sports roles, Ministry of Trade, Industry and Energy (산업부) for manufacturing engineering and 뿌리산업 roles, Ministry of Health and Welfare (복지부) for healthcare roles. Not all E-7 occupations require 고용추천서 — it is mandatory only where the occupation's own screening criteria say so, and it is waived when the employer is a university or public institution, or when a large company hires a manager. Verify the requirement for your specific ISCO/KSO occupation code with the Ministry or through HiKorea.
The 고용추천서 application process (step by step)
Step 1 — Job posting requirement: Before applying for 고용추천서, the employer must post the job position on the Work24 portal (work24.go.kr) or the Korean Employment Information Service (KEIS) for a minimum period (typically 7 days) to demonstrate that the role was advertised to Korean nationals first. Keep records of the job posting. Step 2 — Prepare the 고용추천서 application package: employment contract (signed), company business registration, company financial statements (recent), job description matching an eligible E-7 occupation code, candidate's degree certificate and work experience documents, company organizational chart showing the role. Step 3 — Submit to the relevant Ministry: submission is via the HiKorea portal (hikorea.go.kr) for most categories, or directly to the Ministry's foreign worker support centre. Step 4 — Ministry review: typically 2–4 weeks. If approved, the 고용추천서 certificate is issued. Step 5 — Immigration application: submit 고용추천서 + all standard E-7 documents to the immigration office with jurisdiction (출입국·외국인청, 사무소 or 출장소; for a visa issuance confirmation, the office covering the company's address) or the candidate's local Korean Consulate abroad.
The GOLD CARD system — an employment recommendation for advanced-technology talent
GOLD CARD (골드카드) is not an employer certification. It is an employment recommendation (고용추천서) for foreign advanced science and technology professionals, issued by KOTRA for the Ministry of Trade, Industry and Energy; the scheme has run since 2000. It covers eight fields — IT, technology management, nanotechnology, digital electronics, biotechnology, transport and machinery, new materials, and environment and energy — at public or private organisations. The candidate needs one of: 5 or more years of experience in the same field; a bachelor's degree plus at least 1 year of experience; or a master's degree or higher (a degree earned in Korea removes the experience requirement). With a GOLD CARD recommendation the employer may apply for the visa issuance confirmation online through the Korea Visa Portal (visa.go.kr) with only the recommendation letter attached; the remaining documents are submitted at alien registration.
Required documents for E-7 sponsorship
The employer must provide: ① Employment contract (근로계약서) — bilingual (Korean + English or the worker's language), signed by both parties, specifying position, salary, duties, start date, and duration ② Business registration certificate (사업자등록증) — issued within 3 months ③ Corporate registration certificate (법인등기부등본) — for corporations ④ Company financial statements (매출 증빙) — showing operational capacity ⑤ Organizational chart — showing the applicant's role in the company structure ⑥ Explanation of why the role cannot be filled by a Korean national ⑦ If 고용추천서 was obtained: include the certificate. The employee must provide: ① Passport ② Degree certificate(s) — apostilled and translated ③ Work experience certificates — from prior employers, translated ④ Resume/CV ⑤ Criminal background check — apostilled national-level check from home country ⑥ Passport-size photos. All foreign documents must be apostilled (or consular legalised if from a non-Hague country) and accompanied by Korean or English translation.
Salary requirements and the occupation minimum wage table
The Ministry of Justice (MOJ) announces a minimum salary for each E-7 tier every year. For 1 February to 31 December 2026 it is KRW 31.12 million per year for E-7-1, KRW 25.89 million for E-7-2 and E-7-3, and KRW 26 million for E-7-4. Occupations for which the Ministry has set a separate standard (some shipbuilding trades, for example) follow that standard instead. The employment contract salary must clearly meet or exceed the occupation minimum. Immigration officers will verify this — an underpaid offer is a common rejection reason. The full occupation minimum salary table is published on the HiKorea portal.
Filing with immigration and processing timeline
Applications are filed at: ① The immigration office with jurisdiction (for a visa issuance confirmation, the office covering the company's address) — for example the Seoul Immigration Office (서울출입국·외국인청, in Mok-dong, Yangcheon-gu) or regional offices for in-country status changes ② The Korean Consulate or Embassy in the applicant's home country for applications from abroad. Standard processing time: 2–4 weeks for straightforward applications. With 고용추천서: add 2–4 weeks for the Ministry review step before immigration filing. With a GOLD CARD recommendation: the visa issuance confirmation can be applied for online with only the recommendation letter attached. Complex or first-time applications may take 4–8 weeks. Status can be tracked online via HiKorea (hikorea.go.kr) using the application receipt number. Prepare for possible supplementary document requests (보완 요청) — respond promptly as these pause the clock.
Tips from 행정사s
Post the job on Work24 before beginning the 고용추천서 process — the domestic job posting is a prerequisite, not a parallel step.
A GOLD CARD recommendation is issued for an individual candidate in an advanced-technology field (through KOTRA), not as a standing certification for the company — check whether each new hire's field and background qualify.
The employment contract must be signed before filing — a letter of intent alone is not sufficient for the immigration application.
Salary must be stated as a gross annual or monthly KRW figure — dollar or euro denominated contracts create complications and should be converted to KRW in the contract.
Criminal background checks from some countries take 6–12 weeks — advise your candidate to start this process the moment an offer is made, in parallel with other document collection.
For 뿌리산업 (root industries: casting, mold and die making, metal forming, welding, heat treatment, surface treatment), the recommending Ministry is MOTIE (산업부) and the process has some unique document requirements — check the MOTIE foreign worker support guidance.
If an E-7 worker changes their role significantly within the same company (different occupation code), a new E-7 application may be required — confirm with immigration whether the change warrants a status update.

Visa Process
Alien Registration Card (ARC)
The Alien Registration Card (ARC) is the official ID card issued to foreigners staying in South Korea for 91 days or longer. It is required to open a bank account, sign a phone contract, and access most public services.
Visa Process
HiKorea
How to use HiKorea (www.hikorea.go.kr) — Korea's official immigration portal for visa extensions, status changes, and ARC renewal. Processing time: 3-10 business days.
Visa Process
Visa Extension (Stay Period Extension)
A visa extension — officially called a 'stay period extension' (체류기간 연장) in Korean immigration law — allows a foreigner to legally remain in Korea beyond the expiry date on their current visa or ARC without leaving the country.
Visa Process
Status of Sojourn Change (체류자격 변경)
A status of sojourn change allows a foreigner already in South Korea to switch from one visa category to another without leaving the country — for example, from a D-2 student visa to an E-7 skilled worker visa upon graduation and employment.
Frequently asked questions
Can a startup with no revenue sponsor an E-7 visa?
In some cases, yes. Startups with limited operating history face higher scrutiny, but several pathways exist: ① Startup with government incubator status (창업진흥원 승인 기업, TIPS programme, or similar) — immigration gives these companies more flexibility ② D-8-4 tech startup investors who have pivoted to needing an E-7 employee ③ Companies that can demonstrate funding (Series A+ or documented investment) in lieu of revenue. The key is demonstrating that the company is genuine and has the capacity to pay the stated salary. A startup lawyer or 행정사 familiar with tech company HR is worth consulting before filing the first E-7.
What happens if the E-7 employee resigns or is terminated?
If an E-7 employee leaves the company (voluntarily or involuntarily), both the employer and the employee have notification obligations to immigration. The employer must report the end of employment to the Korea Immigration Service within 15 days. The employee's E-7 visa becomes a provisional status — they have a limited window (often 1–3 months) to find a new E-7-eligible employer and file for a workplace change, or transition to D-10 job seeker status, or depart Korea. The employer does not face penalties for the employee's departure itself, but failure to notify immigration can result in fines. Never attempt to keep an employee's visa tied to your company after the employment relationship ends — this creates liability.
Do we need a Korean employee ratio to sponsor E-7 workers?
Yes. Korean immigration tracks the ratio of foreign workers (in certain categories) to Korean employees. While the rules vary by company size and occupation, a general principle is that companies with fewer Korean employees face more scrutiny when sponsoring multiple E-7 workers. For occupations subject to the employment protection review (most E-7-1 professional roles are exempt), a company with fewer than 5 Korean employees that mainly serves the domestic market cannot, in principle, sponsor at all, and E-7 workers are capped at 20% of the company's Korean employees — 5 Korean employees allow 1 E-7 worker, 10 allow 2. A company already above 20% is in principle refused new invitations, status changes and workplace changes. Maintaining accurate employment insurance records (고용보험 가입 내역) for Korean employees is essential, as these records are used to verify headcount.
Can we pre-screen a candidate's eligibility before making an offer?
Yes — and it is strongly recommended. Before extending a formal offer, verify: ① The candidate's occupation matches one of the 94 E-7 occupation codes ② The candidate's education and experience meet the minimum for that code ③ The candidate's nationality does not create any special restrictions for the occupation ④ If 고용추천서 is required for your occupation, confirm your company is eligible to apply for it ⑤ Confirm the salary you plan to offer meets the E-7 occupation minimum for that code. An 행정사 can do a pre-assessment review of the candidate's documents (in 2–5 business days typically) before the formal offer is extended, saving significant time and protecting both parties from an untenable situation.
