Short answer: British citizens don't need a visa for Vietnam for stays of up to 45 days, with a full British citizen passport valid for at least 6 months. If you plan to stay longer than 45 days, or you travel on a passport that isn't covered, such as British National (Overseas), you need a visa. The easiest option is the eVisa: up to 90 days, $25 single or $50 multiple entry.
The 45-day exemption: what it covers
- Tourism, family visits and short business meetings. Not paid work.
- Counted from your arrival day. Day 1 is the day you land.
- Entry through airports, land borders and seaports.
- No application, no fee. At some airports you still complete the free pre-arrival declaration.
You can't extend a visa-free stay inside Vietnam. If you know you'll stay longer than 45 days, get an eVisa before you travel.
When a British traveller needs a visa
| Situation | What you need |
|---|---|
| Trip of 45 days or less, British citizen passport | Nothing. Visa-free. |
| Trip longer than 45 days | eVisa (up to 90 days) |
| British National (Overseas) passport | eVisa. BNO is not covered by the exemption. |
| Other British passports (e.g. overseas territories) | Check before you travel. Usually an eVisa. |
| Working in Vietnam | A work visa and permit through the employer |
Leaving and coming back
There is currently no waiting period between visa-free stays. You can leave, for example to Cambodia or Thailand, come back and start a new 45-day period. Immigration officers can still question very frequent back-to-back entries. If you are really living in Vietnam, get the right visa rather than relying on border runs.
Is an eVisa worth it for a shorter trip?
For most trips under 45 days: no. Visa-free is simpler. The eVisa makes sense if your plans might stretch past 45 days, or you want certainty for a trip around day 40–45. Choose multiple entry if you'll leave and come back inside that period.
Staying longer than 45 days?
Get a 90-day eVisa. From $48, government fee included, checked before you pay.
