BANGKOK — Thailand will reduce the visa-free stay permitted for tourists from 60 countries and territories from 60 days to 30 days starting September 15, the Foreign Ministry said.

The change is part of the government’s efforts to tackle crimes involving foreign nationals, as Thailand continues to rely heavily on international tourism for its economy.

Authorities have recently arrested several foreigners over alleged offences including drug trafficking, sex trafficking and running businesses such as hotels and schools without the required permits.

According to CNA, under the existing visa exemption scheme, tourists from more than 90 countries and territories can enter Thailand without a visa and remain in the country for up to 60 days.

The affected group of 60 countries and territories includes Singapore, China, the United States and 27 European Union member states, according to the Foreign Ministry’s Department of Consular Affairs.

However, the ministry has not clarified whether visa-free arrangements for about 20 other countries will also be affected. A Foreign Ministry official declined to comment on the matter on September 1.

Meanwhile, visitors from Peru, Brazil and South Korea will receive longer visa-free stays of up to 90 days, compared with the previous 60-day limit.

Tourists affected by the new 30-day limit will be allowed to apply for a single extension, subject to the discretion of an immigration officer.

The government had approved the measure in May as part of wider efforts to prevent abuse of Thailand’s visa system.

Foreign Minister Sihasak Phuangketkeow said at the time that the shorter visa-free period was intended to address cases involving foreigners who exploited the system to commit crimes in Thailand.

Despite the changes, tourism remains a major contributor to Thailand’s economy. Official figures showed that 20.9 million foreign tourists visited the country between January and the latest reporting period this year, representing a 3 per cent decline from the same period in 2025.
