In 2026, the rules for entering Thailand should be checked before buying tickets and once again before departure. At the moment, citizens of 93 countries and territories can enter Thailand without a visa for up to 60 days. This procedure has been in effect since July 15, 2024, and applies to tourist trips, business trips, and certain short-term work assignments.

At the same time, the permitted length of stay should not be treated as a fixed rule for the whole of 2026. On May 13, 2026, Reuters reported that Thailand’s Ministry of Foreign Affairs planned to submit a proposal to the Cabinet to reduce the visa-free period for tourists from 60 to 30 days, fortunately without any specific dates so far.

In addition, all foreign nationals entering Thailand must complete a digital arrival card before arrival. It is required for immigration control and applies to entry by air, land, and sea. It must also be completed for children, including infants.

In this article, we will look at what documents are required to enter Thailand in 2026, how long you can stay in the country without a visa, whether it is worth taking out medical insurance, and much more.

Rules for Entering Thailand in 2026

To enter Thailand in 2026, a tourist should check four things: the visa regime for their citizenship, the validity of their passport, whether they need to complete the Thailand Digital Arrival Card, or TDAC, and the documents confirming the purpose of the trip.

The basic set of documents for a tourist trip is as follows:

  • Passport. It is better to have at least 6 months of validity remaining. The Thai Embassy in Moscow states that the passport must be valid for at least 6 months on the date of departure from Thailand.
  • Visa or the right to visa-free entry. This depends on citizenship, the purpose of the trip, and the length of stay. Since July 15, 2024, citizens of 93 countries have been eligible for visa-free entry for up to 60 days, but in May 2026, Thai authorities announced plans to reduce this period to 30 days.
  • Thailand Digital Arrival Card, TDAC. This must be completed online within 3 days before arrival. It is required when entering by air, through a land border, or via a sea checkpoint. The exceptions are transit without passing through passport control and entry with a Border Pass.
  • Return ticket or onward ticket to a third country. This is needed to confirm the intention to leave Thailand within the permitted period of stay. This check often takes place at flight check-in.
  • Accommodation address. A hotel, apartment, or villa booking is suitable, as is the address of the host. These details are also entered in the TDAC.
  • Proof of funds. The Thai Embassy in Moscow gives the following guideline: 10,000 baht per person or 20,000 baht per family. In practice, this document is usually not requested from everyone, but may be asked if additional questions arise about the purpose of the trip.
  • Medical insurance. For ordinary tourist entry, it is not always a mandatory border requirement, but without it, the tourist assumes the cost of medical treatment, hospitalisation, injuries from road traffic accidents, and emergency evacuation.

Visa-free entry means that a tourist does not need to obtain a visa in advance and does not need to apply for a visa at the airport. A visa on arrival applies only to citizens of certain countries and is issued directly at the point of entry.

Thailand Digital Arrival Card

The Thailand Digital Arrival Card, or TDAC, is an online form that foreign nationals complete before entering the country. It does not grant the right to enter Thailand. Its purpose is to provide the immigration authorities in advance with information about the traveller, their route, accommodation address, and health status.

Who must complete the digital arrival card:

Category

Is TDAC required?

Tourist arriving in Thailand by plane

Yes

Tourist entering across the border with Laos, Cambodia, Malaysia, or Myanmar

Yes

Cruise ship passenger passing through immigration control

Yes

Foreigner with a long-term visa or residence permit

Yes

Transit passenger not passing through passport control

No

Foreigner entering with a Border Pass

No

The TDAC must be submitted within 3 days before arrival in Thailand. This period includes the day of entry. For example, if a tourist arrives on November 20, the form can be completed from November 18. The system may not allow the required arrival date to be selected earlier than that.

To complete the digital arrival card, the following information is usually required:

  • Personal details. First and last name as shown in the passport, date of birth, citizenship, and gender.
  • Passport. Passport number, country of issue, and expiry date.
  • Trip details. Date of arrival, method of entry, flight number, or transport details.
  • Address in Thailand. Hotel, apartment, villa, or the address of the host.
  • Contact details. Email address and, if necessary, phone number.
  • Medical information. Details requested in the health declaration section.

If a tourist changes hotels during the trip, the form usually indicates the first accommodation address in Thailand. For a package tour, this may be the hotel listed on the voucher. For an independent trip, the first accommodation booking, apartment address, or host details will be suitable.

After submitting the form, the tourist should save the confirmation on their phone and make a backup copy. A printout is usually not mandatory, but it may help if the phone runs out of battery, there is no internet connection, or questions arise at flight check-in.

Errors in the digital arrival card are best corrected before departure. If an error is found before the trip, the traveller should go to the official TDAC website and check whether it is possible to update or resubmit the information. If the error is discovered only after arrival, the issue is handled with an immigration officer, but it is better not to let the situation reach that point.

How Many Days You Can Stay in Thailand Without a Visa

The period of visa-free stay in Thailand depends on the tourist’s citizenship and the rules in force on the date of entry. Since July 15, 2024, visa-free entry for up to 60 days has been introduced. This scheme applies to citizens of 93 countries and territories, and the stay may be extended for up to another 30 days at the discretion of the immigration authorities.

The period of stay should be counted not from the date the ticket was purchased and not from the date the Thailand Digital Arrival Card, or TDAC, was completed, but from the actual date of entry into Thailand. When passing through passport control, a stamp is placed in the passport showing the date until which the tourist is allowed to stay in the country.

Trips with non-refundable tickets, long-term accommodation rentals, and itineraries without a flexible departure date should be planned especially carefully. If a tourist buys a ticket for the 45th or 55th day of their stay, and by the time of entry the 30-day rule is in effect, the airline may ask questions already at flight check-in. The immigration authorities may also ask the tourist to explain on what grounds they plan to stay in the country longer than the permitted period.

How to Extend Your Stay in Thailand

If the permitted period of stay is not enough, a tourist can apply for an extension at a Thai immigration office. The extension is processed at the immigration office in the place of stay. In some provinces, online submission is available through the E-Extension service, but it does not work for all categories and does not remove the need to check the requirements of the specific office.

The standard set of documents usually includes:

Document

What to prepare

Passport

Original and copies of the main pages

TM.7 form

Application for extension of temporary stay

Photo

Usually 4 × 6 cm, recently taken

Copy of the page with the entry stamp

Needed to confirm the current period of stay

Accommodation address

Hotel, apartment, rental agreement, or host’s address

Fee

1,900 baht

Additional documents

May depend on the office and the grounds for extension

It is best to apply a few days before the permitted period expires. This leaves a time buffer in case additional copies, photos, address confirmation, or corrections to the application form are needed.

Main list of documents for entering Thailand:

  • Passport. The passport must be valid for the entire period of the trip. In practice, it is better to allow for at least 6 months of validity.
  • Digital Arrival Card. The TDAC must be completed before arrival in Thailand. All information is entered in English. It is best to save the TDAC confirmation on your phone, in your email, and as a screenshot.
  • Return ticket or onward ticket to a third country. A return ticket shows that the tourist plans to leave Thailand within the permitted period. This is important for visa-free entry, travel without a clear itinerary, long stays, and frequent repeat entries.
  • Proof of accommodation. The accommodation address is needed for the digital arrival card and may be required if questions arise at the border. For a short trip, a booking for the first hotel is usually enough. For a longer itinerary, you can prepare several bookings or explain that part of the accommodation will be booked during the trip.
  • Proof of funds. For tourists with a visa and those entering under the Visa Exemption scheme, the indicated guideline is 20,000 baht per person or 40,000 baht per family.
  • Medical insurance. In Thailand, treatment for foreigners is charged at commercial rates. Even a short hospital stay can cost significantly more than the trip itself.

For a trip to Thailand, a child needs a document with which they will cross the border. In practice, the most reliable option is the child’s own passport. A digital arrival card must be completed for every child, including infants.

If a child is travelling without their parents, adoptive parents, guardians, or trustees, notarised consent to travel is required from one of the legal representatives.

Long-Term Visas: DTV, Student Visa, Retirement Visa, and Other Options

If a trip to Thailand goes beyond an ordinary holiday, visa-free entry and a tourist visa are not always suitable. For spending the winter in Thailand, studying, remote work, medical treatment, family residence, business, or retirement relocation, the visa category should be chosen according to the actual purpose of stay.

Destination Thailand Visa, DTV

The Destination Thailand Visa, or DTV, is suitable for those who plan to live in the country longer than the usual tourist period but do not work for a Thai employer.

The Thai Embassy lists three main purposes for this visa: work during a long-term stay, including digital nomads, remote workers, foreign specialists, and freelancers; Thai cultural and wellness programmes, including Muay Thai, Thai cooking courses, and medical treatment; and spouses and children under 20 years old of the visa holder.

The Destination Thailand Visa is valid for 5 years and is a multiple-entry visa. Among the mandatory requirements for applicants is a bank statement showing a balance of at least 500,000 baht. Remote workers and freelancers must additionally provide an employment contract, a certificate of employment, or a professional portfolio confirming the applicant’s status.

For Thai cultural and wellness programmes, participation in the relevant activity must be confirmed. This may be an acceptance letter from the organiser or training centre, or a letter confirming an appointment with a medical institution. Family members of the visa holder must confirm the relationship, for example with a marriage certificate, birth certificate, or adoption document.

Student Visa, Non-Immigrant ED and ED Plus

The student visa, Non-Immigrant ED, is intended for foreigners entering Thailand for educational purposes. To apply, an applicant usually needs a letter from a school, training centre, university, or another organisation in Thailand. The document must confirm that the applicant has genuinely been accepted onto a programme and that the purpose of entry is related to study.

A separate option, the enhanced student visa, Non-Immigrant ED Plus, was created for foreign students studying at Thai universities at bachelor’s level or higher.

Family Visa, Non-Immigrant O

The Non-Immigrant O family visa is issued to spouses of Thai citizens, dependents of foreigners who work or study full-time in Thailand, as well as volunteers and employees of non-governmental organisations.

For the spouse of a Thai citizen, documents confirming the marriage are required, along with the Thai spouse’s documents, a sponsorship letter, and financial proof. The embassy requirements specify a bank statement showing at least 400,000 baht for the last 2 months or proof of annual income equivalent to an average of 40,000 baht per month.

For dependents of a foreigner who works or studies in Thailand, it is necessary to confirm the relationship, the status of the main applicant, their visa or permission to stay, and their connection with the employer or educational institution.

Retirement Visa, Non-Immigrant O-A

The long-stay retirement visa, Non-Immigrant O-A, is intended for applicants aged 50 and older who want to stay in Thailand for up to 1 year and do not plan to work.

For this category, passport requirements are stricter: it must be valid for at least 18 months and have at least one completely blank visa page. A medical certificate confirming the absence of diseases from the prescribed list is also required.

After entry, the holder of an O-A visa may be permitted to stay for up to 1 year from the date of first entry. If the person wants to leave Thailand and return during this period, they need to obtain a re-entry permit; without it, the current permission to stay may be cancelled.

Business and Work Visa, Non-Immigrant B

This category is intended for work in Thailand, doing business, working at a private school or educational institution, as well as certain special purposes, such as sports contracts or short-term training at a private company.

A visa alone is not enough to work in Thailand. The applicant usually needs a package of documents from the employer, including proof of qualifications, an approval letter from the Ministry of Labour or documents under form WP3, as well as corporate documents of the Thai company.

Long-Term Resident Visa, LTR

The official programme of Thailand’s Board of Investment identifies four categories: wealthy global citizens, wealthy pensioners, work-from-Thailand professionals, and highly skilled professionals. Spouses and children of holders or applicants in these categories may also apply as dependants.

The stated advantages of the LTR include multiple entry, exemption from a separate re-entry permit, reporting of stay once a year instead of the standard 90-day reporting, the possibility of obtaining a digital work permit for the relevant categories, and support through a specialised service centre.

The LTR is not suitable for most ordinary tourists or winter visitors. This category requires the applicant to maintain the declared conditions throughout the validity period of the visa, including investments, employment status, account balances, and insurance coverage.
