How Foreigners Can Join Korea’s National Health Insurance (NHIS)
A clear, practical guide for living safely and comfortably in Korea
Korea is one of the few countries where healthcare feels both advanced and accessible.
Clinics are everywhere, waiting times are short, and treatment quality is consistently high.
For foreigners living in Korea, the real turning point comes when they join NHIS — the National Health Insurance Service.
NHIS is not just an insurance program.

It’s the system that makes Korea’s medical experience affordable, predictable, and safe.
Understanding how it works can completely change your life here.
This guide is designed for foreigners who want a simple, reliable explanation of how NHIS works and how to join it.
⭐ Do Foreigners Need NHIS? Yes — It’s Mandatory After 6 Months
If you stay in Korea for 6 months or longer, you must join NHIS.
This rule applies to:

- Foreign residents with an Alien Registration Card (ARC)
- Long‑term visa holders
- International students
- Employees on work visas
- Marriage visa holders (F‑6)
- Overseas Koreans living in Korea
Once you are considered a long‑term resident, NHIS becomes mandatory, not optional.
⭐ Why NHIS Matters (The Benefits Are Huge)
1) Medical costs drop by 30–80%
Korea’s healthcare is already affordable, but NHIS reduces most treatment costs dramatically.
2) Prescription medication becomes very cheap
Foreigners are often surprised by how low the prices are once insurance is applied.
3) Dental and Korean traditional medicine are partially covered
Scaling, cavity treatment, and some Korean medicine treatments receive insurance benefits.
4) Free or discounted health checkups
Korea’s health screening system is world‑class.
NHIS members receive regular checkups at little or no cost.
5) Immediate access to Korea’s fast medical system
With NHIS, you can fully benefit from Korea’s efficient clinics and hospitals.
⭐ How to Join NHIS (Step‑by‑Step)
Joining NHIS is simple.
Korea’s medical system is designed to be fast and easy to navigate.
1) Receive your Alien Registration Card (ARC)
You must have an ARC and live in Korea for 6 months.
2) NHIS sends you a registration notice
A letter will arrive at your registered address.
It includes your insurance category, monthly fee, and payment instructions.
3) Visit a nearby NHIS office or register online
If you visit in person, bring:
- Passport
- ARC
- Address information
- Bank account (for automatic payments)
Online registration is also available and increasingly easy for foreigners.
4) Pay your first monthly fee
Once the payment is made, your NHIS benefits begin immediately.

⭐ How Much Does NHIS Cost?
It depends on your situation.
1) Employees (Work Visa Holders)
Your monthly fee is based on your salary.
Your employer pays half, and you pay half.
2) Students, freelancers, or unemployed residents
You become a regional subscriber.
If you have no income, you pay the minimum fee, usually around:
₩70,000–₩130,000 per month
(Varies slightly by year)
This is extremely affordable compared to other countries.
