Thailand Visa & Entry Requirements
Thailand operates one of the most welcoming visa regimes in Southeast Asia, offering visa-free or visa-on-arrival access to citizens of over 90 countries. For UK citizens, entering Thailand is straightforward — but understanding the rules prevents future complications.
UK Citizens — Visa Exemption
UK passport holders do not need a visa for tourist visits of up to 60 days. This is a visa exemption (not a visa-on-arrival), meaning you simply present your passport at immigration, receive a stamp, and enter.
Requirements at Entry
- Passport valid for at least 6 months from date of arrival
- Proof of onward travel — a return or onward flight ticket. In practice, this is rarely checked at airports but more frequently requested at land borders. Budget airlines and overland carriers may refuse boarding without it.
- Proof of funds — Immigration may ask for evidence of 20,000 baht per person (or 40,000 per family) in cash or equivalent. This is seldom requested but can be enforced, particularly at land borders.
- Completed arrival/departure card — The TM.6 form, distributed on flights and available at border checkpoints.
Extension
The 60-day visa exemption can be extended by 30 days (total stay: 90 days) at any Thai Immigration office. Cost: ฿1,900. Required documents: passport, TM.6 departure card, one passport photo, and a completed TM.7 application form. The process typically takes 1–3 hours.
Key Immigration offices:
- Bangkok: Immigration Bureau, Government Complex, Chaeng Wattana Road
- Chiang Mai: Promenada Mall, 3rd floor
- Phuket: Phuket Town, Phuket Road
- Koh Samui: Immigration office near Nathon

Overstay Penalties
Thai immigration takes overstays seriously:
| Overstay Duration | Penalty |
|---|---|
| 1 day | ฿500 |
| Per day thereafter | ฿500/day (max ฿20,000) |
| Caught by police while overstaying | Detention, fine, deportation, and ban re-entry (1–10 years depending on overstay length) |
If you discover you've overstayed, present yourself voluntarily at an immigration office or at the airport on departure. Voluntary surrender is treated more leniently than being caught.
Land Border Notes
"Visa runs" — exiting and re-entering Thailand to reset the visa-exemption clock — were once common for long-stayers. Immigration has cracked down significantly:
- Multiple entries at land borders may trigger additional scrutiny
- Immigration officers have discretion to refuse entry or grant shorter stays
- Two consecutive visa-exemption entries at land borders is generally fine; more than three in succession may raise questions
Air arrivals face less scrutiny than land arrivals for re-entries.
Health Requirements
- No mandatory vaccinations for entry (unless arriving from a yellow fever area, in which case proof of yellow fever vaccination is required)
- COVID-19 vaccination certificates are no longer required (as of 2023)
- Recommended vaccinations: Hepatitis A and B, Typhoid, Tetanus/Diphtheria. Consider Japanese Encephalitis and Rabies for extended rural travel.
