Thailand tightens visa rules to limit illegal stays

Thailand has tightened visa rules for foreigners as immigration authorities aim to limit long-term stays based on tourist exemptions and step up their crackdown on illegal activities involving foreign nationals.

The changes took effect last week and now restrict the length of stay for travelers in Thailand on visa-exempt entries or tourist visas. Foreigners can now extend their stay only twice, with the first extension for 30 days and a second extension for just seven days. This is a significant reduction from before, when visitors could stay longer without securing a proper long-term visa. For nationals from countries entitled to 60-day visa-exempt stays, the total maximum stay through extensions now drops to 97 days. Those entering on 30-day stays will be limited to a maximum of 67 days.

Immigration officials have also moved to limit “visa runs,” where travelers exit and re-enter Thailand to reset their stay period. Same-day border runs are no longer permitted, and anyone attempting more than two runs risks being denied entry. Immigration checkpoints at airports and land borders have been instructed to refuse entry to travelers who repeatedly attempt to enter without a valid reason.

The stricter rules come amid growing concerns over how some foreign nationals are using tourist entries to live and work illegally in Thailand, including involvement in online fraud operations in border areas linked to networks in Myanmar, Cambodia and Laos.

According to the Immigration Bureau Chief Pol Lt Gen Panumas Boonyalak, the restrictions were implemented after reviewing cases of foreigners repeatedly entering under visa-exempt rules. In some areas with a high concentration of expatriates, organized border trips have enabled visitors to extend their tourist stay for several years, creating loopholes that are exploited for money laundering, illegal employment and unlicensed business activities.

Officials say these tighter controls are aimed at preventing misuse rather than limiting tourism. Travelers with standard itineraries and confirmed return flights are expected to continue entering without issues. Since January, immigration officers have already denied entry to about 2,900 individuals found abusing visa regulations.

Foreigners with a history of previous deportations or those associated with scam networks may also face entry bans, particularly in border regions such as Mae Sot in Tak province. Immigration offices nationwide have been instructed to scrutinize requests for temporary stay extensions, especially cases showing visa-run patterns, which may lead to withdrawal and deportation.

Authorities state that the broader goal is to strengthen border security and ensure that only appropriate visa categories, which are business, education, retirement, or marriage, are used for longer stays. The Immigration Bureau emphasizes that its aim is not to discourage tourism but to attract “quality visitors” who contribute positively to the Thai economy.
