Korea Work Visa: How the System Works — E-Series, Sponsorship and the Employer-Driven Process

The shape of the system

Korea’s work visa system is organised around the letter that starts your visa code. The broad families are:

• E-series — employment in Korea: professors (E-1), foreign language instructors (E-2), researchers (E-3), technical instructors (E-4), licensed professionals (E-5), arts and entertainment (E-6), and the special occupation visa (E-7) that covers most white-collar professional hires.
• D-series — study, investment and job-seeking: the D-8 corporate investor visa for founders, and the D-10 job-seeker status for people already in Korea looking for a role.
• H-series — the H-1 working holiday for nationals of partner countries, and the H-2 work-and-visit status for overseas Koreans from designated countries.
• F-series — residence and settlement statuses such as the points-based F-2, the overseas Korean F-4, permanent residency F-5, and the marriage migrant F-6. These usually come after time on a work visa rather than being first visas.

Which one applies to you depends less on your nationality and more on your job type and the employer’s situation. This article is a map of the system as of August 2026; the specific rules change and are set by the Ministry of Justice.

Who drives the application — the employer

The defining feature of Korean work visas is that the employer drives the process. For sponsored categories such as E-7, the employer applies to the Korea Immigration Service for a Certificate of Confirmation of Visa Issuance (CCVI) — the document that confirms the company, the role and the candidate meet the published criteria.

Only then do you apply for the visa at a Korean embassy or consulate in your country of residence, using the CCVI number with your passport and supporting documents. A foreign worker generally cannot initiate a sponsored application from abroad on their own.

This matters before you accept an offer. The employer must be eligible to sponsor: the company’s business registration, tax compliance, financial standing and staff structure are all assessed, alongside your qualifications. A role that does not map to a designated occupation code, or an employer that fails the corporate criteria, produces a refused application regardless of how strong your CV is.

Picking the right visa for the job

The practical starting point is your occupation:

• English or foreign-language teaching — E-2, at a licensed language institute or school.
• Professional, technical or managerial roles — E-7, tied to a published list of designated occupation codes and a specific employer.
• Professor or researcher — E-1 or E-3 at a university or research institution.
• Starting or investing in a company — D-8, with investment and corporate registration requirements.
• Job hunting from inside Korea — D-10, for people who have studied in Korea or recently left sponsored employment; actual work requires moving to a sponsored status once hired.
• Working holiday — H-1, for nationals of countries with a bilateral agreement.

Each of these has its own dedicated article on this site: E-7 requirements and occupation codes, the E-2 teaching route, the D-8 investor track, the D-10 job-seeker status, the H-1 working holiday and the F-series residence statuses.

Salary, documents and the matching rule

For sponsored categories the assessment covers two parties — you and the employer.

Your side: most professional categories require a qualification that matches the role — typically a bachelor’s degree in a related field plus relevant experience, or substantial experience in lieu of a degree. The rule is matching: a computer science degree fits a software role, while an unrelated degree for the same role usually does not.

Salary: sponsored professional visas carry a minimum salary, published annually and generally referenced to gross national income per capita. The threshold moves every year, so check the figure in force when you apply rather than relying on an older article.

Documents: the typical set includes your passport, degree certificates (apostilled or consular-authenticated with Korean translation), a career certificate describing actual duties and dates, an employment contract, and the employer’s business registration and financial statements. Career certificates are the most common weak point — a one-line letter is rarely enough.

After arrival — the Residence Card

Anyone entering on a long-term visa (90 days or more) must register for a Residence Card — the document formerly called the Alien Registration Card — at the local immigration office within 90 days of arrival. The card is your de facto ID in Korea: banks, phone contracts and the national health insurance all key off it.

Practical points:

• Book the registration early — office slots in busy cities can fill up.
• The card ties your stay to your visa purpose. Changing employers on a sponsored visa requires reporting and, in practice, a fresh assessment of the new employer and role. Do not start at a new company assuming the paperwork will follow.
• If you lose your job, there is a reporting obligation and a limited window to find a new sponsor or change status. Many people move to D-10 while searching.

Note — immigration rules, occupation lists and salary floors are revised periodically and applied differently by individual offices. This article is general information as of August 2026; confirm the current requirements with HiKorea or your local immigration office before acting.
