Thailand is drastically cutting the length of visa-free stays for tourists from more than 90 countries in an effort to curb crime involving foreign nationals, officials said on Tuesday.

Tourism is vital to the south-east Asian nation’s economy, but foreign arrivals are yet to return to their pre-Covid levels.

A recent series of high-profile arrests of foreigners has included cases linked to drug offences, sex trafficking and foreigners operating businesses such as hotels and schools without proper permits.

Under Thailand’s current tourism scheme, travellers from more than 90 countries – including the US, UK, Europe’s 29-nation Schengen area and Australia– are eligible to visit for up to 60 days without a visa.

Thailand’s cabinet on Tuesday approved reducing visa-free stays for travellers from those countries.

The new visa-free duration would be decided on a country-by-country basis, with most foreign nationals granted stays of up to 30 days, while some could receive only 15 days, the tourism minister, Surasak Phancharoenworakul, said.

Tourists will be able to renew visas once by visiting an immigration office, a government spokesperson told Agence France-Presse.

“The 60 days was automatic but the renewal will be decided by the officer and tourists will have to explain why they are staying longer,” she said.

The foreign minister, Sihasak Phuangketkeow, said last week that the plan to reduce visa-free stays was part of a crackdown on transnational crime.

Thailand was not targeting any specific country, he said, but rather individuals abusing the visa system by committing crimes in the country.

Tourists provided “benefits, such as boosting the economy, but the current scheme has allowed some people to exploit it”, a government spokesperson told reporters on Tuesday.

The visa-free period was previously capped at 30 days but was extended to 60 in July 2024 as part of government efforts to boost tourism and the economy.

Tourism accounts for more than 10% of Thailand’s GDP, although visitor numbers remain below pre-pandemic levels.

Foreign arrivals dropped by about 3.4% in the first quarter of this year compared to the same period in 2025, with visitors from the Middle East down by nearly a third, according to government data.

Thailand expects about 33.5 million foreign tourists this year, up from nearly 33 million visitors last year, the government has said.
