Do Vietnam Citizens Need a Visa for South Korea?
Yes. Vietnam passport holders require a visa to enter South Korea for most purposes — visitor, business, study, work, and family categories all need pre-approval. The information below describes the standard process and the most common refusal triggers on this corridor.
Before you apply: the refusal you have to beat
A South Korean C-3 short-term visa is refused when the consular officer is not satisfied you will return — weak evidence of ties to Vietnam, unclear or insufficient funds, or an inconsistent purpose. The decision is made on your documents at the embassy, and the fee is not refunded if you are refused.
The reassuring part: these refusals are almost always preventable. They come down to how your case is presented, not who you are:
- Insufficient or inconsistent proof of funds — single large deposits with no documented source, balances that don't match declared income
- Weak ties to Vietnam — no documented employment, studies, property, or family obligations to show you will return
- Incomplete or mismatched documentation — dates, names, and amounts that contradict between documents
- Unclear or implausible purpose — an itinerary or story the officer has to guess at
Step-by-Step: How to Apply
- Confirm you need a C-3 visa (no K-ETA / e-visa). As a Vietnamese passport holder you must apply for a C-3 short-term visa — you cannot use K-ETA and there is no online tourist e-visa. Ignore third-party sites claiming otherwise.
- Prepare your documents. Assemble your passport, application form and photo, proof of funds with a stable history, proof of employment or business or study, a travel itinerary and accommodation, and an invitation plus host documents if visiting family. Make sure everything is consistent.
- Apply at the Korea Visa Application Center. Submit your application at the KVAC in Hanoi or Ho Chi Minh City (or the Korean Embassy/Consulate). Pay the consular visa fee and the KVAC service fee — confirm the current amounts first.
- Wait for the decision. Standard processing is around 20 working days; an express option may be available. Do not buy non-refundable flights until your visa is granted.
- Collect your visa and travel. Once approved, collect your passport with the visa. Check the entry type (single or multiple) and validity. The visa lets you travel to Korea; an immigration officer at the airport makes the final entry decision, so carry proof of funds, accommodation, and ties.
Frequently Asked Questions
Do Vietnamese citizens need a visa for South Korea?
Yes. Vietnamese passport holders need a visa to visit South Korea for tourism — the C-3 short-term visa. Vietnam is on Korea's full visa-requirement list, so you cannot use the K-ETA (which is only for visa-waiver nationalities) and there is no online tourist e-visa for Vietnamese applicants. You apply in person through the Korea Visa Application Center (KVAC) or the Korean Embassy/Consulate.
Where and how do Vietnamese citizens apply?
You apply at the Korea Visa Application Center in Hanoi or Ho Chi Minh City (or the Korean Embassy in Hanoi / Consulate General in Ho Chi Minh City), submitting your forms, documents, and — where required — attending in person. There is no online e-visa route for Vietnamese tourists, so be wary of websites claiming to issue a Korean "e-visa" to Vietnamese passport holders.
How much does a Korean C-3 visa cost for Vietnamese applicants?
A consular visa fee applies and differs for single-entry, double-entry, and multiple-entry visas, plus a Korea Visa Application Center service fee. Because these amounts are set by the consulate and change periodically, confirm the current figures with the KVAC or the Korean Embassy before paying rather than relying on third-party sites. The fee is generally non-refundable whether or not the visa is granted.
How long does a Korean visa take from Vietnam?
Standard processing for the C-3 short-term visa is around 20 working days, and some posts offer a faster express service. Apply well ahead of your travel date and do not buy non-refundable flights until the visa is granted. Because the decision is made on your documents, a complete, consistent file is the fastest route to a clean outcome.
Can Vietnamese travellers get a 10-year multiple-entry Korean visa?
The scope of the C-3 multiple-entry visa (including a 10-year multiple-entry category) was expanded from the end of March 2026, widening who can qualify. Multiple-entry visas are generally granted to applicants with a strong, compliant profile (stable employment or business, good travel history, sufficient funds). First-time applicants are more commonly issued a single-entry visa; confirm current eligibility with the consulate.
Why are Korean visas refused for Vietnamese applicants?
The consular officer must be satisfied that you are a genuine short-term visitor who will return to Vietnam. Common refusal grounds are insufficient or unexplained funds, weak evidence of ties to Vietnam (employment, business, family, property), an unclear or inconsistent purpose, and gaps or contradictions across documents. A sudden large deposit shortly before applying tends to raise concern rather than reassure.
What documents do I need for a Korean C-3 visa?
Typically: the application form and a photo, your passport, proof of funds (bank statements with a stable history), proof of employment or business or study, a travel itinerary and accommodation details, and — if visiting family or friends — an invitation and the host's documents. Requirements vary, so check the current checklist on the KVAC / Korean Embassy website and make sure every document is consistent.
