80 Got Off the Plane. 38 Vanished. Why Vietnamese Travelers Face Extra Scrutiny at Korean Immigration
On Nov. 14, 2024, a chartered flight from Nha Trang landed at Jeju International Airport. Of roughly 80 Vietnamese nationals who entered visa-free, 38 never boarded their return flight and went silent. Two months later they were reclassified as undocumented overstayers — and six subsequent VietJet charter flights already scheduled were cancelled outright.
Since then, a perception has spread through Vietnam's travel industry that Korean immigration screening for Vietnamese travelers, both in groups and individually, has only gotten tougher. The statistics actually point the other way: according to the Ministry of Justice, about 790,000 travelers from six countries entered Korea on group visas in 2025, up 39% from the year before, while the no-show rate fell from 0.19% to 0.07% — less than half. So why does paperwork still feel so tense for Vietnamese travelers? Because the system itself runs on two separate tracks.
The group-visa fast lane: Since June 2023, a pilot program has let Korean diplomatic missions designate specific travel agencies to handle group tourist visas (C-3-2) for nationals of Vietnam and two other countries. In June 2024, the Ministry of Justice extended the pilot by two years, saying group tourist numbers had doubled. This track simplifies paperwork — but if travelers go missing, the designated agency's standing and the program itself are put on notice; the ministry has explicitly said it will 'monitor no-show rates and review whether to continue.' In effect, one travel agency's credibility shapes how hard the next individual traveler's screening will be.
The paperwork wall for individual travelers: Those not on a group visa (C-3-9) face a different reality. Per the Korean Embassy in Vietnam, individual tourist visa applicants must submit three months of bank statements (including balance verification), while short-term comprehensive visas (C-3-1, e.g. visiting relatives) require an employment certificate and an invitation letter (with a seal certificate if stamped). Travelers who can't produce solid financial or employment proof are the ones most likely to face additional questioning at screening.
Where the door is widening: Ten-year multiple-entry visa eligibility has recently expanded to residents of Hanoi, Da Nang and Ho Chi Minh City, those with a travel history to OECD countries, and employees (and their families) of major Korean-invested companies. The group-visa fee ($15 per person) remains waived through Dec. 31, 2026 for Vietnam and five other countries.
Quick reference: Group visa (C-3-2) — apply only through a mission-designated agency; guides need at least one Korea visit in the past two years; fee waived through Dec. 31, 2026. Individual tourist visa (C-3-9) — bring three months of bank statements with balance verification. Short-term comprehensive visa (C-3-1, e.g. relatives) — employment certificate plus invitation letter (seal certificate if stamped). Ten-year multiple-entry visa — expanded to Hanoi/Da Nang/HCMC residents, OECD travel history holders, and staff of major Korean-invested firms. Apply at the Korean Embassy or consulates in Vietnam.
The gap between sweating it out at the counter over one missing document and simply bringing an extra bank statement isn't large. Whichever visa route you take, packing solid financial and employment paperwork is the surest way to walk through Korean immigration without the tension.
