Visa on Arrival is for tourism and normally permits a stay of no more than 15 days. It is issued only at designated immigration checkpoints, so travelers using a smaller land or sea crossing should verify that VOA processing is available there.
Applicants should be prepared with:
-
Completed VOA application and a recent 4 × 6 cm photograph.
-
Passport valid for the required period, preferably with at least six months remaining and two blank pages.
-
Confirmed onward or return ticket showing departure within 15 days.
-
Evidence of at least THB 10,000 per person or THB 20,000 per family.
-
The THB 2,000 fee, normally payable in Thai baht cash.
-
Accommodation information and a completed TDAC.
Official Thai mission pages are not completely consistent about the minimum passport validity stated for VOA. Following the stricter six-month standard reduces the risk of a carrier or checkpoint applying more demanding guidance.
VOA is generally not extendable for an ordinary holiday. Immigration may consider limited extensions in exceptional situations such as documented illness, but travelers should not plan a longer trip around that possibility.
Who needs a visa before traveling
Ordinary passport holders outside Thailand’s published exemption, bilateral and VOA groups generally need an appropriate visa before departure.
Tourists can start through the official Thai eVisa portal. Thailand has expanded electronic visa processing across its embassy and consular network, but eVisa remains an application method, not a universal entitlement or guaranteed approval.
The system asks for the applicant’s:
-
Passport country or travel-document type.
-
Current physical location.
-
Thai embassy or consulate responsible for that location.
-
Intended visa category and purpose.
-
Travel dates, accommodation and supporting evidence.
Applicants must normally be outside Thailand and apply through the mission responsible for their current location. Nationality alone does not establish which embassy can process the application; proof of lawful residence or presence may be required.
Typical tourist-visa files include the passport biodata page, a recent photograph, proof of current location, travel plans, accommodation and financial evidence. The responsible mission may request additional documents, and fees and processing periods differ.
Approved applicants receive an electronic confirmation by email. Keep the approval accessible and carry a printed copy for airline and immigration checks.
Tourist status does not authorize employment. Longer stays connected with remote work or other qualifying activities belong to a separate immigration route covered in Thailand Digital Nomad Visa: DTV Guide & Income.
Thailand Digital Arrival Card
Every non-Thai national entering Thailand by air, land or sea must complete the TDAC, including visa-exempt visitors, visa holders, VOA applicants, children and infants.
Submit it through the official Thailand Digital Arrival Card portal during the three-day window before arrival, including the arrival date. For example, a traveler arriving on Friday may submit from Tuesday onward.
The form requests:
-
Passport and personal information.
-
Arrival date and flight, vehicle or vessel details.
-
Purpose of travel.
-
Address in Thailand.
-
Countries visited before arrival when relevant.
-
Health-declaration information.
-
An email address for the confirmation.
Each TDAC is valid for one entry only. A new submission is required for a later trip, even when the traveler holds a multiple-entry visa.
The TDAC is an arrival card, not a visa, ETA, health certificate or customs declaration. Completing it does not create visa eligibility and does not guarantee admission.
Travelers may present the confirmation electronically. Keeping an offline copy or screenshot is sensible in case mobile service is unavailable at the checkpoint.
Passengers remaining in international airside transit without passing Thai immigration do not normally submit a TDAC. Once the itinerary requires immigration clearance—for example, to collect and recheck baggage—the passenger is entering Thailand and must meet the relevant visa and TDAC rules.
Passport and supporting documents
Passport condition and validity
Use a passport in good condition with enough blank space for immigration stamps. Thai official pages commonly publish a six-month passport-validity standard, although route-specific wording can differ. Following the six-month standard is the safer approach for airline and border checks.
The name, passport number and nationality on the TDAC, visa and booking documents should match the passport presented at the checkpoint.
Onward travel and accommodation
Keep confirmed onward or return travel within the permitted stay. Airlines may check this before boarding, and immigration can request evidence that the visit is temporary.
The TDAC requires an address in Thailand. Hotel, rental or host details should therefore be available before submission.
Evidence of funds
Thailand has reminded foreign visitors to keep evidence of sufficient funds ready for possible screening. The published amount depends on the entry category rather than one universal figure for every traveler.
For VOA, the stated minimum is THB 10,000 per person or THB 20,000 per family. Different figures may apply to tourist-visa or visa-exempt cases. Funds, payment access or other credible evidence should be available without assuming that every traveler will always be asked.
Health documents
Most visitors do not complete a separate general health form beyond the relevant TDAC questions. Travelers arriving from or after visiting a country designated for yellow-fever controls may need a valid International Certificate of Vaccination.
Where the yellow-fever rule applies, submit the certificate through the official Thailand Health Pass system and carry the original document. Vaccination normally must have been completed at least ten days before travel.
Customs declarations concern goods rather than immigration status. Alcohol, vaping products, food, medication and restricted-item rules are covered separately in Thailand Airport Customs Rules: Alcohol Limits & Vape Ban.
Air, land, sea and transit differences
TDAC registration applies to immigration entry through all three modes, but the available visa route and frequency limits can differ.
Under the active exemption scheme, visa-exempt entries by land or sea are generally limited to two per calendar year. Nationals of Brunei, Indonesia, Malaysia and Singapore are exempt from that stated two-entry limit. This rule should not be treated as permission to use repeated border crossings to extend a holiday.
VOA is available only at designated checkpoints. Confirm availability before using a remote border crossing.
Myanmar’s 14-day bilateral exemption is limited to international-airport arrival. Travelers should not assume it is available at a land border.
International transit depends on the real itinerary, not merely the word “transit” on a booking. Baggage collection, separate tickets, terminal access, an airport change or an overnight stay outside the sterile area may require the passenger to pass immigration.
Transport and airport risks beyond immigration are discussed in Is Thailand Safe? Scams, Taxis & Transport Guide.
Extensions and overstay
Visitors admitted under the current 60-day exemption may normally request an extension of up to 30 days. Tourist-visa holders may also have an extension route, depending on the visa and admission stamp.
Applications are made through Thai Immigration and should be filed before the existing permission expires. Approval is discretionary, and an application does not create a right to remain after the current stamp has expired.
VOA holders should plan to leave within 15 days because ordinary tourist extensions are generally unavailable.
Overstay is an immigration violation. The standard fine is THB 500 per day, capped at THB 20,000, but payment of a fine does not make overstay lawful. Longer overstays or cases discovered before voluntary departure can result in detention, deportation and a re-entry ban.
Check the immigration stamp immediately after entry and treat its expiry date—not the flight-booking date or a general online summary—as the controlling deadline.
Common entry mistakes
-
Treating the approved 30-day reform as active. The current 60-day scheme remains in force until the Gazette-based effective date.
-
Confusing TDAC with a visa. The arrival card is required in addition to the correct visa or exemption route.
-
Applying for VOA despite qualifying for the current exemption. Several passports appear in both published groups.
-
Choosing the wrong eVisa mission. The application location must match the responsible embassy or consulate’s jurisdiction.
-
Assuming airport and land-border rules are identical. VOA availability, bilateral exemptions and land-entry limits can differ.
-
Ignoring the admission stamp. The officer may grant a period that needs to be checked before leaving the counter.
-
Mixing immigration and local-law questions. Vaping, cannabis and visitor conduct are covered in Thailand Tourist Bans & Laws: Vaping, Weed & Fines.
Staying connected after arrival
Mobile data can help with maps, hotel messages, transport bookings, translations, onward tickets and access to stored travel documents. Connectivity has no effect on visa eligibility or the immigration officer’s decision.
Using a Roafly Thailand eSIM can keep essential services accessible without relying on airport Wi-Fi. Broader comparisons are available in How to Get Internet in Thailand: Airport, Local SIM, eSIM & WiFi and Best eSIM for Thailand.
