A D-2 study visa lets you study in Korea. On its own, it does not let you work — not one hour, paid or unpaid, on or off campus. Before an international student can legally earn any income, they need a separate part-time work permit (시간제 취업허가) issued by the immigration office, tied to a specific employer and specific working hours. Students who skip this step because "it's just a part-time job" are, under the Immigration Control Act, working illegally, and the consequences fall on both the student and the business that hired them.
→You Can't Even Apply on Day One
The part-time work permit (시간제 취업허가) generally isn't available immediately after you enroll. Degree-seeking students typically need to complete at least one semester in good standing before immigration will consider an application — the idea being that a student should first show they can handle their coursework before adding a job on top of it. Language institute (어학원) students on a D-4 visa face a longer wait and tighter restrictions than degree-track D-2 students, and are barred from the permit entirely during their first two terms in most cases. Applying before you're eligible doesn't just get rejected — it can flag your file for closer scrutiny on future applications.
→Your Weekly Hour Cap Depends on More Than Just Being a Student
Once eligible, the number of hours you're allowed to work each week during the semester is not a flat number for every D-2 holder. It scales with your degree level (graduate students are generally allowed more hours than undergraduates), your GPA and attendance record from the prior semester, and — for many students — your demonstrated Korean ability, often measured through a TOPIK score or completion of a Korean language program. Students who clear the higher proficiency bar are typically permitted more weekly hours than those who haven't. During the two officially recognized vacation periods each year, the semester-time cap is lifted and full-time work becomes possible with the permit still in place.
| Situation | General Rule |
|---|---|
| First semester on campus | Not yet eligible to apply |
| During the semester | Capped hours, scaled by degree level, grades, and Korean ability |
| Official vacation periods | Cap generally lifted with a valid permit |
| D-4 language institute students | Longer waiting period, tighter caps than D-2 |
Some Jobs Are Off-Limits No Matter What Your Permit Says
A valid part-time work permit doesn't clear you to take any job. Positions at adult entertainment or gambling-related establishments, and a number of other categories the immigration authorities periodically restrict, remain closed to student visa holders regardless of how many hours your permit allows. The permit also names a specific employer and workplace — it isn't a general license to work anywhere. Taking a second job, or switching employers, without reporting the change first is treated the same as working without a permit at all.
The permit is tied to one employer, one set of hours, and one visa status in good standing — change any of those without telling immigration, and the permit stops protecting you.
1Working Without a Permit Puts More Than Just a Fine at Risk
Illegal employment under the Immigration Control Act can result in fines, a shortened visa period, cancellation of your D-2 status, and in more serious or repeated cases, an order to leave the country with a re-entry ban. It doesn't require the job to have been full-time or long-running — immigration authorities have treated a small number of unreported hours as a violation. It also creates a real problem years later: an illegal employment record can complicate a future visa change to a work visa (E-7, for example) or a permanent residency (F-5) application, long after the part-time job itself is forgotten.
2The Employer Is Exposed Too — Which Matters for You
Businesses that hire a student without a valid, matching part-time work permit face their own fines and can be barred from sponsoring foreign workers going forward. In practice, this means some employers who initially agreed informally back out once they understand the paperwork required, or try to pay cash "off the books" to avoid it — which leaves the student with no wage protection at all if a dispute later arises over unpaid hours, since an undocumented arrangement is much harder to prove and enforce.
→What to Actually Do Before You Take a Part-Time Job
- Confirm your eligibility window first — check how many semesters you've completed and your current GPA and attendance standing before assuming you qualify.
- Apply for the permit through your school's international office or HiKorea before agreeing to a start date with any employer.
- Match your actual hours to what the permit allows — a permit for one employer's stated schedule doesn't cover a second job or extra shifts elsewhere.
- Report any change in employer or hours immediately — an outdated permit protects you no better than having none at all.
