BANGKOK, THAILAND – Thailand’s promise of longer visa-free stays in 2025 came with sweeping new controls that have already turned many holidays into costly ordeals.
Digital arrival card replaces paper forms
Thailand introduced the Thailand Digital Arrival Card (TDAC) on 1 May 2025, scrapping the long‑standing blue TM6 paper form that passengers once filled out on the plane. The mandatory online system, required for all foreigners at every border crossing, served as a data tool for the Immigration Bureau, the Health Ministry and the Tourism Authority and had to be completed within 72 hours before arrival.
Travellers who landed in Bangkok without the required QR code were removed from regular passport queues and forced to register on the spot, often battling overloaded airport Wi‑Fi and long lines at a few terminals. The resulting hours‑long delays and stress increased the risk of mistakes during subsequent questioning by border officers and could trigger additional complications.
Fake TDAC sites and confusion over future ETA
Authorities reported a sharp rise in scams involving counterfeit TDAC websites in 2025, where criminals used search ads to mimic the official tdac.immigration.go.th portal. These sites charged between 20 and 100 US dollars for a service that was in reality completely free while harvesting passport details, flight data and accommodation addresses, creating a high risk of identity theft.
At the same time, many visitors mixed up TDAC with the planned Electronic Travel Authorization (ETA), searching for “Thailand ETA” and ending up on the wrong platforms. According to the guidance, the ETA system, designed as a pre‑approval scheme for visa‑exempt travel, had been delayed over technical issues and was not operational as of December 2025, whereas TDAC was only a data registration step and did not itself grant entry.
Cash checks under Section 12 leave tourists stranded
Despite the global shift to cards and mobile payments, Thailand’s immigration officers continued to rely on Section 12 of the Immigration Act to deny entry to travellers who could not prove sufficient means of support. Foreigners selected for inspection had to show at least 20,000 baht in cash per person or 40,000 baht per family, in baht or major foreign currencies; cards, apps and printouts were often rejected at officers’ discretion.
Reports from December 2025 highlighted a spike in refusals at Bangkok’s Don Mueang airport, a hub for budget airlines, where backpacker‑type travellers with multiple regional stamps were escorted to secondary screening. Those who tried to rely on ATMs were told machines were located airside, inaccessible before clearance, and when they failed to produce cash they were taken to detention rooms and required to buy the next flight back at their own expense.
Crackdown on ‘visa runs’ and overuse of tourist status
The extension of visa‑free stays from 30 to 60 days for nationals of 93 countries in 2024/2025 encouraged some visitors to attempt near‑permanent residence via repeated “visa runs” to neighbouring states. In response, authorities revived a stringent “Good Guys In, Bad Guys Out” policy in 2025 to target those using tourist entries for de facto residence or undeclared work, including digital nomads without proper visas.
Land borders were given a strict cap of two visa‑exempt entries per calendar year; a third attempt at crossings such as Poipet or Aranyaprathet could leave travellers stuck in no‑man’s‑land, forced to arrange costly flights or wait weeks for a regular visa. At airports, immigration computer systems flagged visitors with patterns such as three or four 60‑day stays per year, prompting intense questioning and, in some cases, refusal of entry or shorter permitted stays.
E‑visa errors prove costly and irreversible
Thailand’s shift to a central e‑visa platform made online applications the only route for stays beyond visa‑free allowances, with physical consulates largely stepping back. The system was described as highly inflexible, enforcing a “location principle” under which applicants had to be physically present in the country covered by the processing embassy at the time of filing.
Typical failures included attempts by visitors already in Thailand on visa‑exempt entries to apply for a new visa online for a future trip while still in the kingdom. When systems or officials detected Thai IP addresses or conflicting flight data, applications were rejected without explanation and high fees were lost, with no refunds available.
Passport data mismatches and poor uploads derail approvals
The e‑visa platform required absolute consistency with the machine‑readable zone of the passport, making common mistakes such as confusing “O” and “0”, omitting middle names or mistyping passport numbers particularly risky. In some cases, visas were either denied or issued with incorrect numbers, leaving holders vulnerable to refusal at the border when officers saw mismatches between the e‑visa and the physical document.
Low‑quality document uploads also led to immediate denial. Screenshots from banking apps rather than formal PDF statements, or selfie‑style photos that failed biometric standards, were routinely rejected, and because the process offered no opportunity for clarification or correction, incomplete or blurred files could render an entire application void.
Vaping ban enforced with heavy fines and jail risks
Thailand’s tough stance on e‑cigarettes and vaping devices remained one of the least understood dangers for tourists, even as such products were openly sold on some Bangkok street markets. Importing these items breached the Export and Import of Goods Act, while possession violated consumer protection orders, exposing foreigners to fines of 20,000 to 50,000 baht and prison sentences of up to 10 years, even for personal use.
Police activity reportedly intensified in 2025, with uniformed and plain‑clothes officers conducting checks in tourist hotspots such as Sukhumvit Road and Patong Beach. Visitors caught with vapes were often confronted with the law and pushed to pay large sums to avoid detention, a practice that raised ethical and legal concerns but left most travellers with little realistic alternative on the spot.
Powerbank seizures at airports over labelling rules
Airports in Thailand enforced IATA rules on lithium‑ion batteries strictly, banning all powerbanks from checked baggage and limiting carry‑on devices to under 100 watt‑hours without special approval. Units between 100 and 160 Wh were allowed only with airline consent and in small quantities, while larger batteries were prohibited and subject to immediate confiscation and destruction.
The most common trigger for seizures was missing or unreadable capacity labels, particularly on cheap no‑name products from China that lacked clear watt‑hour markings. Security staff removed any device whose rating could not be verified, and there was no avenue for passengers to reclaim expensive powerbanks once taken.
Six‑month passport validity and damage checks
Thailand applied a firm requirement that passports be valid for at least six months on arrival, regardless of planned length of stay, leaving no room for exceptions at the border. Airlines typically refused boarding to passengers whose documents fell short, fearing liability for return transport if they were rejected on arrival.
Officers also stepped up scrutiny of physical damage, rejecting passports with water exposure, peeling laminate, missing or torn pages or pronounced warping. Travellers had previously been turned away over a single centimetre‑long tear, with documents classified as “damaged passports” and therefore invalid for international travel.
Cannabis U‑turn and tight control of medicines
After a period in which Thailand was seen as the “Amsterdam of Asia”, the government reversed course in June 2025, reclassifying cannabis flowers as controlled herbs and officially restricting use to medical purposes. Tourists who continued to buy cannabis in remaining shops without medical consultation or certificates and who consumed it publicly or in hotels faced fines of 25,000 baht or up to three months in jail for causing a public nuisance through smell.
Strict rules also applied to prescription medicines under the oversight of the Food and Drug Administration (FDA). Category‑2 narcotics such as codeine, fentanyl or methadone required special online approval at least 14 days before arrival, while psychotropic drugs like diazepam, alprazolam or lorazepam were limited to 30 days’ supply and had to be carried in original packaging with an English‑language doctor’s note, or risk being treated as drug smuggling.
Onward ticket proof shifts risk to airlines
For visa‑exempt entries, Thai regulations demanded evidence of onward or return travel within the 60‑day allowance, a condition airlines were obliged to enforce at check‑in. Carriers that transported passengers without such proof risked fines and had to bear the costs if travellers were refused entry and flown back.
Travellers who appeared at counters in cities such as Frankfurt or Zurich with only a one‑way flight and no onward booking were often denied boarding after presenting bus or rail tickets to neighbouring countries, which staff did not recognise as sufficient. In practice, a dated flight out of Thailand within the permitted period was the safest accepted form of proof.
TM30 address reporting trips up Airbnb guests
Section 38 of the Immigration Act required property owners and landlords to report every foreign guest to local immigration within 24 hours via form TM30. Hotels handled this electronically as routine, but many operators of private rentals and short‑term Airbnb‑style stays failed to comply, either out of neglect or to avoid scrutiny in buildings whose rules banned short lets.
The omission usually surfaced only later, when foreigners sought services such as a 30‑day stay extension, a 90‑day report or replacement documents. If officers found no TM30 record for the current address, they halted proceedings and, in practice, often fined the foreigner between 800 and 2,000 baht and could refuse processing until the landlord filed the report, a step that might be impossible once the guest had moved on.
Customs limits and hidden post‑control checks
Customs officers enforced tight allowance rules on arrival, limiting each person to one litre of alcohol and 200 cigarettes or 250 grams of tobacco products, with no pooling of quotas within couples or groups. Travellers who carried multiple duty‑free allocations in a single bag for others were treated as personal owners and faced penalties of 10 to 15 times the value of the excess goods, along with immediate confiscation.
In Bangkok, surveillance extended beyond the official red‑and‑green channels, with plain‑clothes officers monitoring passengers after baggage reclaim and watching for multiple duty‑free bags or bulky luggage. Purchases made on the aircraft, in transit or at foreign duty‑free shops all counted against the same limits and offered no protection from fines.
Airport taxi scams add to arrival stress
At Suvarnabhumi Airport, tired arrivals were frequently approached in the arrivals hall by touts offering “official limousines” or “VIP taxis” to downtown Bangkok for flat rates of 1,500 to 2,000 baht. In reality, a metered public taxi from the official stand on Level 1 typically cost around 350 to 500 baht including the 50‑baht airport surcharge and tolls, meaning many visitors paid several times the normal fare.
Even at official ranks, some drivers used so‑called “turbo meters” that ran artificially fast or demanded hefty, unregulated baggage surcharges and claimed traffic justified fixed prices. The advice was to insist on the meter or to use app‑based services such as Grab or Bolt from designated pick‑up zones, where fares and routes were recorded and displayed in advance.
Preparations now crucial to “Land of Smiles” trips
With digital border systems expanding and data from multiple agencies increasingly linked, Thai authorities moved towards near‑total visibility over visitors’ movements, visa histories and compliance. Plans for a fully operational ETA by 2026 and wider use of biometric facial recognition aimed to speed clearance for compliant travellers while immediately flagging irregular patterns and past violations.
Officials framed the evolving regime as a way to welcome “good” tourists—solvent, respectful and temporary—while deterring those seen as abusing tourist statuses for long‑term residence or undeclared work. Commentators concluded that spontaneous, lightly planned backpacking in Thailand had become far riskier and that careful preparation and respect for every rule were now essential to enjoy the country’s enduring appeal.
