Walk through Sinchon at 12:55 on a weekday and you will see it: a wave of students from dozens of countries spilling out of the language institutes, all carrying the same coloured textbooks, all looking for lunch.

The 어학당 (eohakdang), the university Korean language institute, is how tens of thousands of foreigners start their life in Seoul. It is also a visa: enrol at one and you can stay in Korea on a D-4 language training visa, term after term.

This is Part 5 of our Living in Seoul 101 series. Below are the 2026 prices and formats for eight of the best-known institutes, all taken from the universities’ own admission pages.

The short answer

  • A 10-week regular term costs ₩1.65–1.86 million in 2026, plus an application fee of ₩80,000–150,000 and textbooks.
  • Classes run four hours a day, Monday to Friday, about 200 hours per term, in morning or afternoon sessions.
  • Terms longer than 90 days need a D-4-1 visa, applied for at a Korean embassy with the institute's admission certificate.

How much does a Korean language institute cost in Seoul?

Most regular programs charge ₩1.78–1.86 million per 10-week term in 2026. SNU’s afternoon class (₩1.65 million) is the cheapest standard option in this comparison; Yonsei and Sogang’s morning class (₩1.86 million) the most expensive. Several institutes raised prices during 2026, so check which term a fee applies to.

How are the Seoul language institutes different?

The format is almost identical; the teaching style, class size and neighbourhood are not. All eight run 10-week terms, four hours a day, levels 1 to 6. The differences are in what those four hours feel like and what surrounds the classroom.

Yonsei University Korean Language Institute (KLI)

The oldest and one of the largest: Yonsei says around 1,700 students from about 60 countries enrol each term. Placement is by speaking and writing test, and TOPIK scores are not used. Classes run mornings (9:00–13:00) or afternoons (14:00–17:50). The campus sits in Sinchon, Seoul’s densest student neighbourhood; see our guide to Sinchon and Ewha cafés.

Seoul National University Language Education Institute (LEI)

SNU’s Korean Language Education Center runs identical programs in the morning and afternoon, and prices the afternoon class ₩150,000 lower (₩1.65 million against ₩1.8 million). The morning class runs 9:00–13:00 in four 50-minute periods; classes hold roughly 12 to 16 students. The campus is in Gwanak, in southern Seoul, far from the Sinchon cluster, which suits people who want a quieter base.

Korea University Korean Language Center (KLC)

Korea University describes its general course as a communicative, integrated class, and runs an academic Korean track with presentations, discussion, writing and TOPIK classes for students heading into degree programs. Classes are capped at 14. The campus is in Anam; our Anam and Bomun guide covers where to eat.

Sogang University Korean Language Education Center (KLEC)

Sogang’s reputation is speaking. The centre says it introduced Korea’s first communication-focused teaching method in 1990, and that students spend more than two hours speaking in each four-hour lesson, using its own Sogang Korean textbooks. Teachers act as facilitators rather than lecturers. If your goal is to talk rather than to pass a grammar exam, this is the one people recommend. Sogang also runs an evening course (Monday, Tuesday and Thursday, 18:50–20:40, ₩700,000 per term) for people with daytime jobs.

Ewha Womans University Language Center (ELC)

At Ewha’s Korean intensive program, tuition rises to ₩1.85 million and the application fee to ₩120,000 from the Winter 2026 term; textbooks cost ₩53,000–60,000 a term on top. It shares the Sinchon–Ewha student neighbourhood with Yonsei and Sogang.

Sungkyunkwan University (SKKU) Korean Language Center

The lowest application fee in this comparison (₩80,000), and tuition of ₩1.78 million, below every other institute’s morning class; only SNU’s afternoon class is cheaper. SKKU switched from six terms to four a year from 2026. Classes of 10 to 15 run in four 50-minute periods, mornings or afternoons, with a stated focus on Korean for academic purposes and culture. The Seoul campus is near Hyehwa, in the old university district by Daehangno.

Hanyang University Institute of International Education (IIE)

Hanyang lists ₩1.85 million per term with a ₩150,000 application fee, the highest application fee in this comparison, and about ₩55,000 for textbooks. The Seoul campus is at Wangsimni, next door to Seongsu; our Wangsimni and Haengdang guide covers the neighbourhood.

📍 Open in Naver Map

Kyung Hee University Institute of International Education (IIE)

Kyung Hee’s selling point is the afternoon: after core grammar, speaking and reading classes, students choose cultural subjects such as Korean drama and K-pop, or practical ones such as pronunciation clinic, debate and TOPIK preparation. It also offers native-language counselling and Korean student helpers. From Fall 2026 the application fee is charged once instead of every term. The campus is in Hoegi, northeast Seoul; see our Hoegi and Kyung Hee guide.

Choosing between them

  • Want to speak fast? Sogang's method is built around it.
  • Heading into a Korean degree? Korea University's academic track, or any institute's upper levels with TOPIK preparation.
  • Working or on a budget? SNU's afternoon class and SKKU are the cheapest regular options; Sogang's evening course costs less still.
  • Want the student-town experience? Yonsei, Sogang and Ewha sit within walking distance of each other in Sinchon.
  • Want more than grammar? Kyung Hee's afternoon electives.

What visa do you need to study Korean in Seoul?

For a course longer than 90 days at a university-affiliated institute, you need the D-4-1 Korean language training visa. Stays of 90 days or less use the short-term C-3-1 visa instead. Private academies and lifelong-learning centres, even those attached to universities, cannot sponsor a D-4 visa.

The process, according to the Ministry of Education’s 2026 Study in Korea guidebook:

From application to visa

  • Apply to the institute and pay tuition by its deadline. The institute then issues a standard certificate of admission.
  • Prove your finances. The principle is enough for one year of tuition and living costs (six months for language study), shown by bank balance certificates issued within 30 days, bank books or scholarship letters. Parents' statements need a family relationship certificate.
  • Show your education: at least a high school diploma, or a certificate of enrolment.
  • Apply at the Korean embassy or consulate for your country of residence or where you last studied.
  • Register within 90 days of arrival for your residence card (Part 1).

Documentary requirements are stricter for nationals of some countries; Sogang’s admission page, for example, lists 21 countries designated by the Minister of Justice for extra financial checks. Ask your institute which documents apply to your passport.

Can language students work part-time in Korea?

Yes, but only after six months and only with permission. D-4-1 students become eligible for part-time work six months after their status began (or after entry, for visa holders), and must get a part-time work permit from immigration before starting. Under the rules in force since July 2023, the limit is 10 hours a week, or 20 hours for students with TOPIK level 2 or an equivalent Korean qualification (25 on weekdays at certified universities for students with good grades).

Our guide to part-time jobs in Korea shows where the jobs are.

Attendance matters. Institutes track attendance closely because immigration looks at it when you extend your D-4 stay. Missing too many classes can cost you your visa, not just your level.

When should you apply?

Two to four months before the term starts. Institutes need time to issue the admission certificate, and you need time for the visa.

If you already live in Korea on another visa, ask the institute whether you can change status to D-4 without leaving; the answer depends on your current visa.
