Vietnam e-visa caps your time in Vietnam at 90 days per visit. The statute attaches its consequence at 91 days or more, so 90 is the last safe count. Ninety days, single or multiple entry. Visa-free agreements for some nationalities are shorter — 45 days is the usual figure.
Who it applies to
This matters most if you are:
- A visitor on a short-stay visa or visa waiver making several trips a year.
- A long-term traveller stitching stays together and losing track of the cumulative count.
- Anyone booking a return trip who needs to know the last day they may legally stay.
The rule — and why it exists
Vietnam visit length. At most 90 days in Vietnam per visit — written as <=90 / VISIT.
Why it exists: a short-stay allowance is a promise to leave. The cap, and the way it is counted, is what lets a state admit visitors without treating every visit as immigration.
Counting the days
- Count the days of each stay in Vietnam on its own, arrival and departure days included.
- No single stay may exceed 90 days.
- Leaving and re-entering starts a new stay — but frequent or back-to-back visits invite refusal as a de facto resident.

Examples
Example 1 — A stay of 80 days
Stays: Vietnam 2026-03-01 → 2026-05-19. Checked on 2026-05-19.
Result: Vietnam visit length: 10 of 90 days left (80 used in Vietnam).
Example 2 — A stay of 95 days
Stays: Vietnam 2026-03-01 → 2026-06-03. Checked on 2026-06-03.
Result: Vietnam visit length: over the limit — 95 of 90 days, first exceeded 2026-05-30.
Example 3 — Two visits of 62 days each
Stays: Vietnam 2026-01-10 → 2026-03-12; Vietnam 2026-06-01 → 2026-08-01. Checked on 2026-08-01.
Result: Vietnam visit length: 28 of 90 days left (62 used in Vietnam).
Exceptions & edge cases
- National visas and residence permits. Days spent under a long-stay visa of that country are usually not short-stay days.
- Transit. Airside transit generally does not count; a day on which you cross the border does.
- Overstays. Even a single day over can mean a ban or refused entry; the engine reports the first breaching day.
Common misconceptions
- "Under 90 days means I'm safe." False — other tests can apply, and the count is only one input.
- "I can chain visits." Each visit is counted alone, but a pattern of back-to-back visits is treated as residence.
- "Arrival day doesn't count." Any part of a day inside is a day inside.
Frequently asked questions
Is the 90-day count per calendar year or rolling?
Each single stay. Each stay is measured on its own.
Do arrival and departure days count?
Yes — any part of a day counts as a day.
