Thailand’s Immigration Bureau has revealed the results of its proactive enforcement campaign, reporting that 29,490 foreign nationals were denied entry, during the first five months of 2026 under its “Three No’s” strategy aimed at tackling transnational crime and preventing foreign offenders from operating in the country. Get today's headlines by email On 4 June 2026, Pol Maj Gen Cherngron Rimphadee, deputy commissioner and spokesperson for the Immigration Bureau, said National Police Chief Pol Gen Kitrat Phanphet had ordered a nationwide crackdown on transnational criminal networks and foreigners posing as tourists who may threaten Thailand’s security, economy and society. Immigration Bureau Commissioner Pol Lt Gen Phanumas Boonyalak said all immigration divisions nationwide had been enforcing the policy since the start of 2026 through the “Three No’s” approach: no entry, no stay, and no escape. The first measure, “No Entry”, focuses on preventing unwanted individuals from entering Thailand. Authorities use the Advance Passenger Processing System (APPS) to block foreign nationals listed on Thailand’s blacklist, including those previously imprisoned in the country and individuals subject to Interpol notices. The blacklist currently contains 169,506 names, preventing those individuals from boarding flights to Thailand, while anyone attempting to enter through land border checkpoints is refused entry. Immigration officers have also increased scrutiny of travellers entering under visa-free schemes. Those interviewed and found to display behaviour suggesting they intended to work illegally or may have links to scam operations relocating from neighbouring countries were denied entry. Between January and May 2026, a total of 29,490 people were refused entry under this measure. The second measure, “No Stay”, targets foreigners who violate the conditions of their visas. Authorities have revoked visas for individuals who entered legally but engaged in activities inconsistent with their visa category, particularly student visa holders not undertaking genuine studies. From 1 January to May 2026, 668 people were denied permission to remain and were deported. Immigration authorities have also conducted nationwide inspections and enforcement operations against foreign offenders. Between 1 January and April 2026, a total of 14,161 foreign nationals were arrested for various offences. The final measure, “No Escape”, involves intelligence gathering and cooperation with local police forces. Between January and May 2026, immigration officers identified 190 foreign-related targets in communities considered at risk of affecting public order, particularly in major tourist destinations. The targets included 147 in Chonburi, two in Mae Hong Son, nine in Chiang Mai, 22 in Surat Thani and 10 in Phuket. Searches have so far resulted in 31 arrests, while investigations into the remaining targets continue. Khaosod reported that authorities said immigration and police units will continue monitoring high-risk individuals and communities as part of ongoing efforts to prevent criminal activity and strengthen enforcement across Thailand.
