FAQ
Where do I apply for a Korean visa in Vietnam?
At the Korean embassy or consulate in Vietnam, or the visa application center it designates. Check the embassy notice for jurisdiction and how to submit.
Does a K-ETA or visa guarantee entry?
No. The immigration officer makes the final decision. Be ready to show your accommodation, return ticket and itinerary.
When and where do I submit the e-Arrival Card?
From 3 days before arrival, free of charge, on the official site (e-arrivalcard.go.kr). Beware of paid look-alike sites.
I am visiting family in Korea. What is different?
If your country needs a visa, an invitation letter and guarantee from your family help a lot. See the invitation guide for the documents.
