National Health Insurance in Korea (NHIS) is mandatory for most foreign residents staying in the country long term.
If you’re planning to live in South Korea, NHIS is one of the first systems you’ll need to understand. It provides access to affordable healthcare and helps reduce the cost of hospital visits, medical treatment, and prescription medications.
Whether you’re wondering who needs to enroll, how much it costs, what it covers, or what happens if you don’t pay, this guide walks you through everything you need to know.
⚡ Quick Takeaway
If you’re staying in South Korea as a long-term resident, you’ll generally be required to join National Health Insurance (NHIS).
- ✅ Employees are usually enrolled automatically through their employer.
- ✅ Most other residents become eligible after meeting the residency requirements, while some visa holders qualify immediately.
- ✅ NHIS helps reduce the cost of hospital visits, clinic appointments, and prescription medications.
- ✅ Missing premium payments may affect your visa status and health insurance coverage.
❓ Is National Health Insurance (NHIS) Mandatory for Foreigners?
Yes. Most foreigners who live in South Korea for six months or longer are required to enroll in National Health Insurance (NHIS).
This rule has applied since July 2019 and covers most long-term visa holders, including:
- ✅ E-2 (English Teachers)
- ✅ E-7 (Professionals)
- ✅ D-2 (International Students)
- ✅ F-Series Visa Holders
- ✅ Other eligible long-term visa holders

⚠️ What Happens If You Don’t Pay?
Failing to pay your NHIS premiums can affect both your health insurance coverage and visa status.
| Issue | What It Means |
|---|---|
| 🚫 Visa Renewal | Your visa renewal or extension may be delayed or restricted until overdue premiums are paid. |
| 💳 Overdue Premiums | Unpaid premiums remain your responsibility and may be collected under Korean law. |
| 🏥 Medical Coverage | Your NHIS benefits may be suspended, and you may have to pay the full cost of covered medical services until your account is up to date. |
💡 Important: Having private health insurance does not automatically exempt you from NHIS if you’re required to enroll under Korean law.

| When do you join? | Shortly after starting work | Usually after 6 months of residence (some visa holders qualify earlier) |
| Who pays? | Employer and employee share the premium 50/50 | You pay the full premium yourself |
