Planning a trip to South Korea? ✈️ If you’re from a visa-free country, you can no longer just book a flight and show up. Since 2021, South Korea requires most travelers to obtain a K-ETA (Korea Electronic Travel Authorization) before boarding their plane. In this in-depth guide, we explain everything you need to know about K-ETA in 2025: who needs it, how to apply, how much it costs, how long it lasts, and the most common mistakes to avoid.
Complete Guide to K-ETA
1. What Is K-ETA?
K-ETA stands for Korea Electronic Travel Authorization, an online pre-screening system introduced by the Korean government. It is mandatory for travelers from over 110 visa-free countries who plan to enter South Korea for short stays such as:
- 🏖️ Tourism
- 🛍️ Shopping
- 🧳 Transit
- 🤝 Business meetings
- 👨👩👧 Family visits
Once approved, your K-ETA is valid for 2 years or until your passport expiry date, allowing you to enter Korea multiple times without reapplying.
2. Why South Korea Introduced K-ETA
South Korea launched K-ETA to simplify border procedures, strengthen immigration security, and streamline airport arrivals. Before K-ETA, visitors from visa-waiver countries could enter without formal screening. K-ETA now helps:
- Enhance national security post-COVID
- Pre-screen travelers before arrival
- Reduce airport immigration lines
- Digitize visitor records
3. Who Needs K-ETA in 2025?
Travelers from over 100 visa-waiver countries must obtain K-ETA before visiting Korea for:
- Tourism
- Business meetings
- Attending events or conferences
- Short-term family visits
📝 Travelers with valid visas, diplomats, or those from visa-required countries do not need K-ETA.
4. Is K-ETA a Visa?
No, K-ETA is not a visa. It’s an online travel authorization system.
| K-ETA | Visa |
|---|---|
| Online approval | Issued by consulate |
| 24–72 hrs processing | 1–4 weeks |
| Short-term stays only | Covers more purposes |
K-ETA is only for short-term, non-working visits. If you’re coming for study, employment, or long-term stay, a visa is required.
