A K-ETA is valid for 3 years and covers multiple entries, so short trips out of Korea and back do not require a new application. Each entry is assessed on its own, and the officer sets the permitted stay again.
What does not reset
- The visa-waiver arrangement itself — you cannot use repeated entries to turn a 30-day arrangement into permanent residence
- Your K-ETA validity — it still expires on its original date
- The record of how you have been using it
Repeat visits attract questions
Korea, like most countries, treats visa-waiver entry as being for visits. A pattern of leaving for a few days and returning each time your stay runs out is visible in the system, and an officer can refuse entry even with a valid K-ETA.
What to have ready on re-entry
- An onward or return ticket
- Your accommodation address in Korea
- Something showing you are going home: work, study, family

If you are currently exempt from the K-ETA (until 31 December 2026), you do not need one for these trips at all. Check your eligibility before paying anything.
More about K-ETA
After you land
K-ETA gets you on the plane. What comes after — arrival card, e-gates, cash, tax refunds, transport, healthcare, emergencies — checked with official sources.
Tax refund
Visitors get VAT back on purchases of KRW 15,000+ at tax-free shops. On-the-spot refunds: under KRW 1,000,000 per purchase, KRW 5,000,000 per trip.
Liquids and power banks
Carry-on liquids: 100 ml containers in one sealed 1 litre bag. Since 20 April 2026, at most 2 power banks per person, and no charging on board.
Passport and details
The K-ETA is linked to the passport you applied with. A renewed passport ends it early, and mismatched details stop you at check-in.
At the border
Immigration, quarantine and customs are three separate checks. Knowing which one asks what is the difference between ten minutes and an hour.
Quarantine
Failing to declare animal or plant products on arrival in Korea can bring a fine of up to KRW 5 million under the Contagious Animal Diseases Prevention Act.
