The expensive mistake is checking Korea’s entry rules after your flight becomes nonrefundable. Start with your passport and nationality, then confirm visa or K-ETA status on an official government site. If you need an e-Arrival Card, submit it only on the free government website within the permitted three-day window before arrival.
Best starting decision: Do not begin with an airline blog or a paid form service. Begin with the Korea Visa Portal, K-ETA notice and official e-Arrival Card navigator.
- Passport validity is an airline and immigration decision; check it before paying.
- K-ETA exemption and visa-free entry are different questions.
- The official e-Arrival Card is free and warns travelers about imitation sites.
Make the decision in 60 seconds
| Your situation | Best move | Check before paying |
|---|---|---|
| You hold a Korean visa | Confirm the visa and use the e-Arrival Card navigator | Name, passport number and intended entry date |
| You normally travel visa-free | Check 2026 K-ETA status for your nationality | Whether the temporary exemption applies to you |
| You already hold a valid K-ETA | Check whether an arrival declaration is excluded | That the K-ETA matches the passport used for entry |
Step 1: confirm the passport you will actually use
Your passport is the anchor for every later check. Confirm the spelling of your full name, passport number, nationality, date of birth and expiration date. Use the same document for the airline booking, visa or K-ETA check, e-Arrival Card and immigration inspection. A second passport, renewed passport or dual nationality can change the answer, so do not copy details from an older trip.
There is no useful one-line “six-month rule” for every visitor. Airlines and immigration authorities apply rules based on nationality, travel document and itinerary. Check with the Korean embassy or consulate responsible for your place of residence and with the operating airline before a nonrefundable purchase. A transit country may also impose a separate document rule.
Step 2: separate visa, K-ETA and arrival card
A visa permits travel for a defined purpose and period. K-ETA is an electronic travel authorization for eligible visa-free travelers. The e-Arrival Card is an entry declaration, not permission to board. Treat them as three separate boxes. The official 2026 K-ETA notice extends the temporary exemption for the countries and regions already covered through December 31, 2026, but it does not turn every nationality into a visa-free nationality.
Use the Korea Visa Portal for the visa path, the official K-ETA exemption notice for authorization status and the e-Arrival Card navigator for the declaration. Save the result and date of each check.
Step 3: prepare the address and flight details
The arrival declaration asks for passport and travel information, including where you will stay. Save the first accommodation’s Korean address, local phone number, arrival flight and planned departure information before you open the form. If you change hotels later, keep the first confirmed address easy to find rather than searching through email at the immigration counter.
The official service allows submission from three days before arrival in Korea and charges no fee. A site asking for payment information is not the official e-Arrival Card service. Since May 2026 the submission flow also includes a verification-code step, so use an email address you can access while traveling.
Step 4: build a document backup that works offline
Keep a screenshot or PDF of your flight confirmation, first hotel, onward travel and any visa or K-ETA approval. The official e-Arrival Card page says carrying the card itself is not required, but knowing the issue number can help. Store copies on the phone and in a cloud account you can reach without a Korean SIM.
A screenshot is a backup, not proof that a rule still applies. Recheck the official source shortly before departure, especially after a passport renewal, itinerary change or government notice. The detailed e-Arrival Card versus K-ETA guide explains the declaration path without mixing it with visa eligibility.
Your final booking checklist
- Match the ticket name to the passport machine-readable page.
- Check visa eligibility on the official Korea Visa Portal.
- Check the dated 2026 K-ETA exemption notice.
- Run the e-Arrival Card navigator with your actual documents.
- Save the first hotel’s Korean address and phone number.
- Confirm the operating airline and terminal, not only the codeshare seller.
- Store approvals and bookings offline.
- Repeat the official check before departure.
Mistakes that cost time or money
- Paying a third-party site for the free e-Arrival Card.
- Assuming K-ETA exemption automatically means visa-free entry.
- Entering with a renewed passport while an approval references the old number.
- Using a social-media checklist without its publication date or nationality scope.
Turn this guide into a real plan
Complete the document check before choosing a nonrefundable fare. Once entry eligibility is clear, reserve the first stay, save its Korean address and decide how you will connect at the airport. That order prevents a booking from forcing a document assumption.
On travel day, keep the official pages bookmarked and carry one offline folder. After landing, follow the airport’s arrival sequence for immigration, baggage and customs, then use the Incheon Airport to Seoul comparison rather than choosing transport while tired.
Frequently asked questions
Is the Korea e-Arrival Card a visa?
No. It is an entry declaration. Visa eligibility and K-ETA status must be checked separately on their official government services.
Does every traveler need K-ETA in 2026?
No. Eligibility and temporary exemption depend on nationality and document status. Check the official K-ETA notice with the passport you will use.
How much does the official e-Arrival Card cost?
It is free. The Ministry of Justice warns that a site requesting payment information is not the official service.
