This page reflects the UK government’s understanding of current rules for people travelling on a full ‘British Citizen’ passport, for the most common types of travel.
The authorities in Thailand set and enforce entry rules. For further information contact the embassy, high commission or consulate of the country or territory you’re travelling to. You should also consider checking with your transport provider or travel company to make sure your passport and other travel documents meet their requirements.
Restrictions in response to coronavirus
Entry and transit
If you want to travel to Thailand, you must apply for permission to travel via the Royal Thai Government’s online platform.
You should keep up to date with the latest information on the websites of the Ministry of Foreign Affairs , Royal Thai Embassy London, Civil Aviation Authority of Thailand, and the Ministry of Public Health.
Residents currently outside Thailand
If you have a Thai resident visa and normally live in Thailand but cannot return within the required year, you will be granted an extension to your compulsory return deadline. However, you are required to return to Thailand as soon as the situation improves.
Certain categories of foreigners arriving in Thailand will be tested for COVID-19 on entry and again during quarantine – see Entry section above.
Most travellers to Thailand, including British nationals travelling from the UK, are required to complete 14 days’ quarantine at a State Quarantine or Alternative State Quarantine (ASQ) facility. Whilst in ASQ, you will normally not be allowed to leave your room except for medical treatment or COVID-19 tests.
In some areas of Thailand it is possible to complete some or all of the quarantine period without being restricted to an ASQ facility. Schemes include the Phuket Sandbox and Samui Plus. You can find out more information on the Royal Thai Embassy London website.
You may be required to download the Thai Chana COVID-19 tracking app on arrival in Thailand.
You need a valid visa to stay in Thailand. If you do not have a valid visa you will be subject to overstay penalties. You should speak to your local Immigration Office or visit the Thai Immigration website.
You are legally required to have a valid passport in Thailand. Any visa you hold will become invalid from your passport expiry date. If you need to renew or apply for a new British passport, see Overseas British passport applications.
If you are unable to renew or change your visa and unable to travel to your home country (because the border is closed, for example) and need support you should contact the Embassy.
Thai authorities may introduce further measures. You can monitor the latest updates from Thailand’s Ministry of Public Health website.
Regular entry requirements
Your passport must have at least 6 months’ validity remaining from your date of entry into Thailand. Entry to Thailand is normally refused if you have a passport which is damaged or has pages missing.
If you’re a dual national, you must depart Thailand on the same nationality passport you used to enter. If not, you may experience difficulties as you pass through immigration.
For current information on entry and visa requirements refer to Restrictions in response to coronavirus.
Under normal circumstances, British passport holders arriving by air or land can enter Thailand for 30 days without a visa (a ‘visa exemption’). If you need to stay longer, it’s possible to extend your stay once for up to 30 days. You must apply for the extension before your visa exemption period ends.
You can only enter Thailand through a land border using the 30 day visa exemption twice per calendar year. To cross more frequently, you’ll need to get the appropriate visa in advance of travelling. This doesn’t apply if arriving by air. For more information, contact the nearest Thai embassy or consulate.
If you plan to stay in Thailand for longer than 30 days, are going to work, or use land borders regularly you must get the appropriate visa before you travel.
The only legal way of getting a new visa, entry permit or extension of stay is from a Thai Embassy or Consulate, an Immigration Officer at a point of entry into Thailand, or one of the Immigration Offices around the country. Visas issued by visa shops, travel agents or by any other means are likely to be illegal and lead to criminal proceedings.
If you stay beyond the period of your visa (‘overstay’), you’ll be fined 500 baht per day up to a maximum of 20,000 baht. You also risk being held in detention, fined, deported at your own expense and banned from re-entering Thailand. The enforcement of penalties for overstaying is strict and conditions in detention centres can be harsh. Deportation by the Thai authorities can be a lengthy process and you will also be banned from re-entering Thailand for up to 10 years.
If you’re living or staying in Thailand on a long-term visa, immigration rules can be complex and are subject to change. It is your responsibility to ensure you meet the requirements of your visa. Stay informed and contact your local immigration office for more information.
Proof of onward travel and funds
Immigration officials in Thailand may ask you for proof of onward travel (e.g. a return or onward air ticket). You should make all reservations before travelling to Thailand. Some airlines have refused to board passengers without evidence of onward travel.
Immigration officials may also ask for evidence of adequate finances and have refused entry to people who could not show this. This is not defined in law and can be interpreted in a number of ways.
To work in Thailand you will need a work permit or business visa. Failure to observe this rule can lead to arrest and deportation.
Yellow fever certificate requirements
Check whether you need a yellow fever certificate by visiting the National Travel Health Network and Centre’s TravelHealthPro website.
UK Emergency Travel Documents
UK Emergency Travel Documents (ETDs) are accepted for entry, airside transit and exit from Thailand. If you’re planning to enter Thailand using a UK ETD, you should contact the nearest Thai Embassy or Consulate before you travel to seek advice about whether a visa is required. If you’re requesting a two-way ETD from Thailand, you must provide proof that you have a non-immigrant visa.
