Thailand to Vietnam visa requirements

Thai ordinary passport holders can visit Vietnam visa-free for up to 30 days per entry. If arriving at Tan Son Nhat (Ho Chi Minh City), complete Vietnam's free Digital Arrival Card before arrival. As of 2026-06-29, Thai ordinary passport holders remain visa-free for Vietnam for up to 30 days per entry under Vietnam's reciprocal visa-exemption arrangements. The official Vietnamese government exemption table lists Thailand with a 30-day stay, and Vietnam's tourism authority lists Thailand among visa-exempt countries. No Vietnamese visa or e-Visa is needed for a normal short tourist, family, meeting, or transit visit within 30 days, but travelers should hold a passport valid at least 6 months from arrival with at least 2 blank pages, plus onward or return travel evidence if asked. Vietnam's e-Visa remains the practical alternative for longer stays or when a fixed pre-approved visa is preferred; the immigration application guide lists USD 25 for single entry and USD 50 for multiple entry, with processing stated as 3 working days, and Vietnam's tourism authority describes e-Visas of up to 90 days. A separate Digital Arrival Card is currently required for foreign passport holders arriving at Tan Son Nhat International Airport (Ho Chi Minh City); it is free, completed online within 72 hours before arrival, and is independent of visa status. Work, study, journalism, residence, or stays beyond the visitor allowance require the appropriate Vietnamese visa or permit.

/06 — The risks

Common refusal reasons

by frequency
/01
Overstaying the 30-day cap
The ASEAN visa-free stay is hard-capped at 30 days. Overstays carry per-day fines and possible re-entry bans.
Low
/02
Frequent back-to-back entries
Border officers can question travellers who appear to use the 30-day cap as de facto residency.
Low
/03
Insufficient travel evidence
No return ticket, vague itinerary, or unclear accommodation can lead to questioning.
Low
/04
Suspected work intent
Visa-free does not cover paid employment. Carrying obvious work gear or pre-arranged contracts can prompt refusal.
Low
/05
Past Vietnamese overstays
Any prior overstay or removal heavily affects future visa-free entries.
Low
/07 — On arrival

After you land

/01
Immigration
