Visa Requirements

Visa Information for TIIKM Conference Participants

Before travelling to Thailand, each visitor is responsible for confirming whether a visa is required and for obtaining the correct immigration permission. A visa, e-Visa approval, or visa-exemption entitlement does not automatically guarantee admission; final entry permission is determined by Thai immigration authorities at the port of entry.

Important Notice:

Visa rules depend on nationality, passport type, purpose of travel, and intended length of stay. Thailand approved revisions to its visa-exemption and Visa on Arrival arrangements in May 2026, with implementation linked to publication in the Royal Gazette. Travellers should verify the latest official requirements immediately before booking and again before departure.

1. Identify the Correct Entry Category

Visa Exemption

Nationals of eligible countries and territories may enter Thailand without obtaining a visa in advance for qualifying short visits. The permitted stay and eligible activities depend on the current visa-exemption scheme or a bilateral agreement. Eligibility and duration can change, so travellers must check the official country list before departure.

Visa on Arrival

Passport holders from designated countries and territories may be eligible to apply for a Visa on Arrival at approved immigration checkpoints. This option is intended for short visits and normally requires a fee, supporting documents, and proof of onward travel. Eligibility is nationality-specific and should be confirmed through an official Thai source.

Tourist Visa

Travellers who are not eligible for visa-free entry or Visa on Arrival, or who require a longer or more predictable period of stay, should apply for a Tourist Visa before travelling. Applications may be submitted through the official Thai e-Visa system where available or through the responsible Royal Thai Embassy or Consulate-General.

Non-Immigrant and Other Visa Categories

Travel for employment, business, study, research, volunteering, family purposes, retirement, or other non-tourist activities may require a specific Non-Immigrant or long-stay visa. Visitors must select a visa that accurately reflects the main purpose of their trip. Tourist entry permission must not be used for activities that require work authorization or another immigration status.

2. Passport and Supporting Documents

Visitors should travel with original documents and retain accessible electronic copies. Immigration officers may request some or all of the following:

A passport or recognized travel document valid for at least six months from the date of entry.

A valid visa or e-Visa approval, when required.

Confirmation of the Thailand Digital Arrival Card (TDAC).

A confirmed return or onward ticket within the permitted period of stay.

Proof of accommodation, such as a hotel reservation or host address.

Evidence of sufficient funds for the visit.

Documents supporting the stated purpose of travel, where applicable.

Border discretion

Immigration officers may ask additional questions or request further evidence. Travellers should ensure that their documents are consistent, current, and accurate.

3. Thailand Digital Arrival Card (TDAC)

All non-Thai nationals entering Thailand by air, land, or sea are generally required to complete the TDAC online before arrival. The TDAC is an arrival registration form and is not a visa.

Submit the TDAC within three days before arrival, including the arrival date.

Use the official TDAC portal; submission is free of charge.

Prepare passport, travel, accommodation, purpose-of-travel, health declaration, and email information.

A new TDAC is required for each entry into Thailand.

Children and infants also require a TDAC.

Transit passengers who do not pass through Thai immigration are generally not required to submit one.

Keep the confirmation or QR code available on a phone or as a printed backup.

4. Applying for a Visa

Visa applicants should apply well in advance and follow the instructions issued by the Thai embassy or consulate responsible for their country of residence. Requirements vary by visa type and location, but commonly requested materials include:

A completed online application form.

A passport valid for the required period.

A recent passport-style photograph.

Proof of legal residence in the country from which the application is submitted, where required.

Confirmed travel arrangements and accommodation.

Evidence of adequate finances.

Supporting letters or documents related to the purpose of travel.

Payment of the applicable visa fee.

Processing times, fees, document standards, and interview requirements differ by embassy and visa category. Applicants should not purchase non-refundable travel arrangements until they understand the applicable visa process and associated risks.

5. Health Requirements

Travellers arriving from or transiting through a country or territory identified by Thailand as a yellow-fever-infected area may be required to present an International Certificate of Vaccination or Prophylaxis for yellow fever. The vaccination generally must have been administered at least 10 days before arrival.

Health screening measures can change in response to public-health developments. Travellers should consult official Thai health and consular sources before departure, particularly when travelling from or through an affected area.

Comprehensive travel and medical insurance is strongly recommended, even where it is not a universal immigration requirement. Visitors should ensure that the policy covers medical care, hospitalization, trip disruption, and emergency repatriation.

6. Arrival in Thailand

At immigration, visitors should be ready to present their passport, visa or e-Visa approval if required, TDAC confirmation, onward travel evidence, accommodation details, and financial evidence. The immigration officer will determine the period of stay granted and record it electronically or by entry stamp.

Check your permitted stay

Before leaving the immigration area, verify the date until which you are permitted to remain in Thailand. The visa validity period and the permitted period of stay are not always the same.

7. Extensions and Overstay

Some entry categories may be extendable through the Thai Immigration Bureau, subject to eligibility, documentation, fees, and officer approval. Travellers who require additional time should apply before their current permission expires.

Remaining in Thailand beyond the authorized period is an immigration offence. Overstay may result in fines, detention, removal from Thailand, and restrictions on future entry. Visitors should monitor their permitted-stay date carefully and resolve any immigration issue promptly through the appropriate authority.

8. Pre-Departure Checklist

☐ Confirm whether your nationality qualifies for visa exemption, Visa on Arrival, or requires a visa in advance.

☐ Check that your passport meets the required validity period.

☐ Apply for the correct visa early, where required.

☐ Complete the TDAC within the official submission window.

☐ Carry return or onward travel confirmation.

☐ Keep proof of accommodation and sufficient funds available.
