About this website. VietNam Visa Korea is a private, independent visa information and support service. We are not the Embassy of Vietnam in Seoul, the Vietnam Immigration Department or any government agency. South Korean citizens can visit Vietnam visa-free for up to 45 days; for longer stays, and for most other nationalities living in Korea, you can apply for a Vietnam e-visa (up to 90 days) yourself on the official portal (evisa.gov.vn) and pay only the government fee (US$25 single entry / US$50 multiple entry). If you use our support service, our service fee is charged separately and shown before payment. Consular procedures for Vietnamese citizens are handled by the Embassy of Vietnam in Seoul; this page is a reference guide only.
Short answer: The most common reasons for being refused boarding to Vietnam at Incheon are an e-visa that does not match the passport, a trip longer than 45 days without a visa, and insufficient passport validity. Airlines can deny boarding if you do not meet Vietnam’s entry requirements.
Main causes
| Cause | How to check |
|---|---|
| Wrong name, date of birth or passport number on the e-visa | Compare the approved e-visa PDF with your passport letter by letter |
| Stay over 45 days with no visa | Return or onward ticket within 45 days of arrival |
| One-way ticket only | Airlines may ask for proof of onward travel for visa-free entry |
| Passport valid less than 6 months, or damaged | Check expiry date and condition |
| Entry airport or date not matching the e-visa | Compare after any flight change |
If it happens at the airport
- Ask the airline exactly which requirement is missing.
- Apply for a new e-visa or correct the error: how to fix e-visa information.
- Consider moving to a later flight.
- Emergency support takes 4–8 working hours (Vietnamese time); weekends and holidays are assessed case by case. Approval cannot be guaranteed.
Prevent it
- Apply 1–2 weeks before departure
- Print the approved e-visa and keep it with your passport
- Re-check airport and dates after flight changes
- Read the 7 common e-visa mistakes
