Korea's visa system can look like alphabet soup at first: D-2, E-7, F-6, H-2 and dozens more. But once you know how to read the codes, the whole thing becomes far less intimidating. Each code is simply a letter that signals a broad purpose — study, work, residence, and so on — followed by a number that narrows it down to a specific situation.

This guide walks through how the codes work and then explains the categories foreigners encounter most often. The goal is to help you recognize where you fit and understand, in plain terms, what your status lets you do — especially around work, which is the area where people most often get into trouble by assuming more than their status allows.

How to read a status code

Every Korean status of stay is written as a letter plus a number, like D-2 or E-7. The letter is the family of visa:

The number after the letter pins down the exact category. D-2 (degree student) is very different from D-4 (language training), even though both start with D.

Single vs multiple entry

A visa can be single-entry (good for one entry into Korea) or multiple-entry (you can come and go during its validity). This is separate from how long you are allowed to stay. If you plan to travel in and out, the entry type matters — and once you are a registered resident, re-entry is handled differently, which we cover in our guide to re-entry permits.

Visa vs status of stay

People use "visa" loosely, but there is a real distinction. A visa is the entry permission stamped or issued before you arrive — it gets you through the airport. Your status of stay (체류자격) is your residency category once you are inside Korea, recorded on your Alien Registration Card. They usually match, but the rules that govern your daily life — how long you can stay, whether you can work — flow from your status of stay, not the entry sticker.

Common visa categories at a glance

The table below summarizes the categories foreigners run into most. Treat the "what it broadly allows" column as a plain-language sketch, not a legal definition — the precise rules for each code live on HiKorea.

CodeWho it's forWhat it broadly allows
D-2Students enrolled in a Korean university/degree programFull-time study; limited part-time work only with prior permission
D-4Language trainees and certain other traineesStudy at a language institute; work is tightly restricted
D-10Job seekers and start-up preparersStaying in Korea to look for work or prepare a business, not to work yet
E-2Foreign language instructorsTeaching a foreign language at an approved institution named in your contract
E-7Skilled workers in designated occupationsProfessional/skilled employment tied to a specific approved job
E-9Non-professional workers (manufacturing, etc.)Employment under the Employment Permit System with an assigned employer
F-2Long-term residentsBroader residence rights; often allows wider work options
F-4Overseas KoreansResidence with relatively broad activity, with some restrictions
F-5Permanent residentsIndefinite residence and broad freedom to work
F-6Spouses of Korean nationalsResidence based on marriage; generally broad work freedom
H-2Working-visit (certain overseas Koreans)Residence plus work in permitted industries

The D series — study and preparation

D visas are about being in Korea for a reason other than ordinary employment. D-2 is the classic degree-student visa; D-4 covers language and other training; D-10 is the job-seeking status that often acts as a bridge for graduates lining up a work visa. None of these are meant for full-time work.

The E series — employment

E visas are work visas, but each one is tied to a specific kind of job. E-2 is built around language teaching at a named institution. E-7 covers a defined list of skilled and professional occupations and is closely linked to a particular employer and role. E-9 is the non-professional employment route, managed under a structured permit system. The common thread: your permission to work is narrow and tied to the exact job in your paperwork.

The F series — residence and family

F visas are the "settling in" family. F-2 is a long-term residence status that often opens up broader work rights. F-4 serves overseas Koreans. F-6 is the marriage visa for spouses of Korean nationals. F-5 is permanent residence — the most stable status short of citizenship, with broad freedom to live and work. Many people aim to move toward F-2 or F-5 over time.

The H series — working visit

H-2 is a working-visit status mainly for overseas Koreans from designated countries, allowing residence together with employment in permitted industries.

Work permissions are strict — take them seriously

The single most important thing to understand is that your right to work is tied to your status, and the boundaries are enforced. Working outside what your status permits — for example, a language student taking on full-time paid work, or an E-7 holder doing a completely different job than the one approved — can put your stay at risk, including fines and worse.

Warning. Even part-time work as a student usually requires prior permission from immigration before you start. Do not assume a "small side job" is fine. Confirm what your specific status allows before earning any money.
Tip. If you want to switch from one category to another — say, from a student visa to a work visa after graduation — that is a change of status, not just an extension. See changing your visa status inside Korea to understand your options and timing.

How to confirm your own category

This overview is a map, not a rulebook. The detailed conditions — eligibility, allowed activities, required documents — differ for every code and are updated periodically. To be certain about your exact situation:

  1. Find your status code on your visa or ARC.
  2. Look it up on HiKorea (hikorea.go.kr), the official immigration portal.
  3. If anything is unclear, call the Immigration Contact Center at 1345, which offers multilingual support.

When it comes time to renew, the process is its own task — read how to extend your visa in Korea without leaving.

The bottom line

Korean visa codes are easier than they look once you see the pattern: a letter for the purpose, a number for the specifics. D is study, E is work, F is residence and family, H is working visit. The categories above cover most foreigners, but the fine print — and especially the rules about what work you can do — is strict and status-specific. Use this guide to orient yourself, then confirm your exact rights and obligations on HiKorea or via 1345 before you make any move that depends on your status.
