The Foreign Office has warned Brits to check their paperwork is in order as a country changes its entry rules.
As of today, Thailand’s entry system has changed. After two years running a generous scheme under which citizens of 93 countries and territories could enter visa-free for stays of up to 60 days, a harsher system has taken over. Effective this morning, the length of stay has been cut in half from 60 days to 30 days for many nationalities.
For US, UK, Australian and Canadian citizens, the principle remains straightforward: no visa is required for a tourist stay of up to 30 days in Thailand. However, the visa-free period has been halved from 60 to 30. If you want to stay in the country for longer than that, you’ll have to apply for an extension of up to 30 additional days. The Thai government has indicated that this should be granted.
Another major change is that the visa-free scheme now applies only to tourists. Those entering the country for work or other purposes now use the visa category corresponding to their activity.
The reform also reintroduces a restriction on land-border entries, with those using the 30-day visa exemption allowed only two land-border crossings per calendar year. Nationals of Brunei, Indonesia, Malaysia and Singapore are not subject to this limit.
Ahead of the changes coming into effect today, the UK’s Foreign, Commonwealth and Development Office (FCDO) issued updated advice to Brits, a record-breaking million of whom visited Thailand last year. The government warned of the consequences of overstaying your visa or visa-free period.
“If you overstay the period of your visa, you will get a fine of 500 Thai baht a day up to a maximum of 20,000 baht. You risk being:
- held in detention
- deported at your own expense
- banned from re-entering Thailand for up to 10 years
“Conditions in detention centres can be harsh.”
Thailand relaxed its visa rules in 2024, expanding the number of countries that qualified for visa-exemption, while extending the maximum length of stay to 60, in a bid to boost its tourism sector post-Covid. Tourism accounts for as much of 20% of the country’s GDP.
However, the rise in visitor numbers has caused tensions in the country. Back in May government spokesperson Rachada Dhanadirek told reporters that while tourism provided “benefits, such as boosting the economy”, the former visa scheme had allowed people to “exploit” the system. Foreigners overstaying and illegally operating businesses in tourism hotspots, without the proper permits, is a particular concern in parts of the country.
The full FCDO advice reads: “From 15 September 2026, if you enter Thailand under the visa exemption scheme, you can stay for up to 30 days for tourism. If you entered Thailand before 15 September 2026, you will usually be allowed to stay for the period granted when you arrived. If you want to stay longer, you must get the appropriate visa before you travel or, if eligible, apply for an extension through the Thai immigration authorities.
“You may be asked to show that you meet the entry requirements. This could include proof that you have enough money for your stay (at least 10,000 Thai baht per person or 20,000 Thai baht per family) and evidence of onward or return travel. British nationals have been refused entry for failing to provide this evidence.
“If you overstay your permission to stay in Thailand, you could be fined, detained, deported or banned from re-entering the country. Make sure you understand the conditions of your stay and get any visa extension you need before your permission expires.”
Alongside the entry guidance, the Foreign Office has revised its advice on Thailand’s rainy season and the dangers posed by heavy downpours.
The rainy season generally runs from May to October across most of the country, and from November to March in Koh Samui and south-east Thailand. However, the updated guidance warns that “weather patterns have become increasingly unpredictable and periods of intense rainfall can occur across Thailand.”
It continues: “Heavy rainfall can cause flash flooding, landslides and disruption to transport, particularly in northern, north-eastern and mountainous areas. Conditions can change rapidly and may result in road closures and local travel disruption. Lakes, caves and waterfalls are particularly at risk of dangerous flash flooding.”
Holidaymakers should follow instructions from local authorities and keep a close eye on weather warnings from the Thai Meteorological Department.
