Important Thailand Immigration & Travel Updates

⚠️ Thailand’s 60-Day Visa-Exempt Stay Has Ended

As of 15 September 2026, Thailand’s visa-exempt stay dropped from 60 to 30 days for most nationalities. For travellers from the United States, the United Kingdom, EU member states, Canada, Australia, Japan, and around 60 countries and territories in total, visa-free entry now means 30 days, not 60.

A smaller number of nationalities are affected differently. Seychelles and Mauritius now get a 15-day exemption instead. Visa on Arrival narrowed to just three countries: Azerbaijan, Belarus, and Serbia.

21 nationalities lost visa-free entry altogether: Albania, Andorra, Colombia, Cuba, Dominica, the Dominican Republic, Ecuador, Guatemala, Jamaica, Kosovo, Mexico, Monaco, Morocco, Panama, Papua New Guinea, San Marino, Sri Lanka, Tonga, Trinidad and Tobago, Uruguay, and Uzbekistan. Travellers from these countries must now apply for an e-Visa in advance via Thailand’s official e-Visa system (up to 60 days as a tourist e-Visa).

For the fully confirmed details, see the official announcement from Thailand’s Tourism Authority (TAT Newsroom), published 1 September 2026.

Read the official TAT announcement of the new 30-day and 15-day visa exemption rules (1 September 2026). (opens in a new tab)

Key takeaway: check which of the four groups applies to your nationality (30-day exemption, 15-day exemption, Visa on Arrival, or e-Visa required) before you travel, since it determines whether you need to apply in advance at all.

Here’s what to do before you fly:

  • Check which list your nationality falls under: 30-day exemption, 15-day exemption, Visa on Arrival, or e-Visa required.
  • Confirm the latest official guidance shortly before departure, since details can still shift.
  • Planning to stay longer than 30 days? Look into a Tourist Visa (TR) through Thailand’s official e-Visa system.

⚠️ Regional Security & Travel Advisory (Status: October 2026)

Some areas of Thailand remain subject to official travel advisories due to ongoing security concerns and border tensions.

  • Thailand–Cambodia border: All land border crossings remain closed following the 2025 border conflict, with no reopening date announced. Overland travel between Thailand and Cambodia isn’t currently possible, but flights (e.g. Bangkok – Phnom Penh, Bangkok – Siem Reap) continue to operate normally. Some governments advise against travel within 50km of the border itself.
  • Thailand–Myanmar border: Increased security measures and restrictions remain in place in some areas.
  • Southern provinces (Yala, Pattani, Narathiwat, and parts of Songkhla): Ongoing security advisories remain in place. Violence has increased since mid-2026: an attack on a security checkpoint in Narathiwat killed five paramilitary rangers in late July, a coordinated wave of more than 50 arson, bomb and shooting incidents hit all three provinces on 22-23 August, and further attacks continued through September, including fatal incidents in Narathiwat. The security situation in Thailand’s Deep South remains unpredictable.

Travellers should avoid non-essential travel to affected regions, follow the guidance of local authorities, and check the latest travel advice issued by their own government.

Outside these regions, tourism in Thailand continues as normal, including Bangkok, Chiang Mai, Phuket, Krabi, Ko Samui and most other destinations throughout the country.


Pre-Arrival Essentials

Do I Need to Apply in Advance?

  • Visa-exempt travelers (around 60 eligible countries and territories, including UK, EU, USA, Canada, Australia, Japan and India): No visa is required, but you must complete the Thailand Digital Arrival Card (TDAC, see below) within 72 hours before arrival. The permitted stay is 30 days for most nationalities. 
  • Nationals of the 21 countries that lost visa-free status on 15 September 2026 (see Important Thailand Immigration & Travel Updates above): You must apply for an e-Visa in advance via Thailand’s official e-Visa system before travelling. 
  • Visa-on-Arrival (Azerbaijan, Belarus, and Serbia): Apply upon arrival at designated immigration checkpoints. A TDAC is also required before travel.
  • Tourist & non-immigrant visas: Apply in advance through Thailand’s official e-Visa system and complete the TDAC within 72 hours before arrival.

Can I just show up?

No, in most cases TDAC must be submitted within 72 hours (3 days) before arrival at air, land, or sea entry points; scans or printouts of the QR code will be checked.


🌐 Thailand Digital Arrival Card (TDAC)

All foreign travellers (with a few exceptions) must complete the Thailand Digital Arrival Card (TDAC) before entry. This digital form replaces the former paper TM6 arrival card.

Step-by-step guide from Thai Immigration on how to submit the Thailand Digital Arrival Card (TDAC)

Key points:

  • Timing: must be completed within 72 hours before arrival in Thailand.
  • Arrival types: applies to air, land, and sea arrivals.
  • Cost: Free of charge.
  • Submission: via the official Thai Immigration website, or through the Immigration Bureau’s official THIM app. Both are free and do the same thing; THIM is an optional alternative, not an extra requirement.
  • On arrival: You will receive a QR code to show upon arrival.

Exemptions: diplomats, Thai citizens, border-pass holders, and those transiting without passing through immigration.

Submit your arrival card on the official TDAC website. Free of charge, no agency needed. (opens in a new tab)

📄 After submitting your TDAC, you’ll go through standard immigration checks on arrival in Thailand. You will still need to present your passport and meet all visa and financial requirements on arrival.

Thailand Digital Arrival Card (TDAC): Common Questions

Is TDAC mandatory?

Yes. All foreign travellers entering Thailand must complete the Thailand Digital Arrival Card (TDAC) before arrival, with limited exemptions such as Thai citizens, diplomats and travellers transiting without passing through immigration.

Is TDAC free?

YYes. Submitting the TDAC is completely free of charge. Only use the official Thai Immigration website or the Immigration Bureau’s official THIM app. No payment is required at any stage of the process.

When exactly must I submit TDAC?

TDAC must be submitted within 72 hours (3 days) before arrival in Thailand. After submission, you will receive a QR code, which must be shown (digitally or printed) at immigration.

What happens if I forget TDAC?

If you arrive without a completed TDAC, you may be asked to submit it before being allowed to proceed through immigration, which can cause delays. In some cases, airline staff may also check TDAC completion before boarding.


⛨ Health Insurance for Long-Term Stays

If you plan to stay in Thailand for more than a short visit, it is helpful to have international health insurance. Long-stay visas such as retirement, marriage, business, digital nomad, and most non-immigrant visas often require or strongly recommend reliable medical coverage.

** Visa on Arrival narrowed from 31 countries to 3 under the same rules.


1. Visa-Exempt Entry for Tourists – 2026

Nationals from around 60 eligible countries and territories (including the UK, EU, USA, Canada, Australia, Japan and India) can enter Thailand without a visa for tourism. As of 15 September 2026, this exemption is tourism-only, business activities or short-term work are no longer covered and require a Non-Immigrant “B” visa instead.

21 nationalities lost visa-exempt status entirely on 15 September 2026 and must now apply for an e-Visa in advance. See Important Thailand Immigration & Travel Updates above for the full list and further details.

If you plan to stay longer than 30 days, or want greater certainty before travelling, consider applying for a Tourist Visa (TR) through Thailand’s official e-Visa system.

A one-time extension may be available at a Thai Immigration Office, usually for THB 1,900, although travellers should always confirm the latest extension rules before departure.

Requirements:

  • Passport valid for at least 6 months
  • TDAC QR code (Thailand Digital Arrival Card)
  • Proof of onward or return travel
  • Evidence of sufficient funds: THB 10,000 per person or THB 20,000 per family (may be checked randomly)
  • Land border entries: visa-exempt travellers can generally enter Thailand through a land border checkpoint no more than twice per calendar year. The cap applies to land crossings only.

⚠️ Important: Overstaying your permitted period can result in fines, detention, deportation, and bans from re-entry.

💡 Frequent visitors: Visa-exempt entry is intended for short-term visits. Repeated visa-exempt entries or frequent border runs are subject to immigration discretion. Travellers may be questioned, refused entry, or denied an extension even if they meet the formal entry requirements.

More details: visa information on the Thai Ministry of Foreign Affairs website

4. Long-Term & Non-Immigrant Visas

For those planning to work, study, retire, volunteer, or join family in Thailand, there are several non-immigrant visa options available.

Retirement Visa “O‑A” / “O‑X”

These visas are intended for foreign nationals aged 50 or older who wish to stay in Thailand long term.

O-A (1 year)

  • For individuals aged 50+
  • Evidence of sufficient funds:
    • Monthly income of at least THB 65,000, or
    • Deposit of THB 800,000 in Thai bank (2 months before applying for visa)
  • Health Insurance

O-X (10 years)

  • For individuals aged 50+ from specific countries (e.g., Japan, Germany, USA)

Retirement visa for part-year / overwintering stays

The Non-Immigrant O-A visa also works well if you don’t want to stay in Thailand the whole year. You don’t need to live in Thailand full-time to keep this visa.

Key points:

  • Multiple entries: you can enter Thailand, stay for a period (often around 180 days), leave again, and freely re-enter within the visa’s 1-year validity
  • No requirement to stay continuously: you can spend part of the year elsewhere without consequences
  • Age-based only: no marriage requirement, also open to single, divorced, or widowed applicants aged 50 and older
  • Not meant for work: the visa doesn’t grant the right to work in Thailand, regardless of your marital status

Financial requirements (apply regardless of how many days you actually spend in Thailand):

  • Monthly income of at least THB 65,000, or a deposit of THB 800,000 in a Thai bank account (held for at least 2 months before applying)
  • Health insurance meeting Thailand’s minimum requirement, in effect since 1 October 2021: total coverage of at least THB 3,000,000 (or USD 100,000) per policy year, including COVID-19 coverage. Check the current amount with the embassy or consulate where you apply.

Documents for your visa application

Beyond the financial and insurance requirements above, the Thai embassy or consulate also asks for a number of separate documents for the application itself. Arrange these in good time, applications often take longer than expected.

  • Medical certificate: confirms you’re free of certain conditions. Usually no older than 3 months at the time of application.
  • Police clearance certificate: proof of good conduct from your country of residence, usually no older than 3 months.
  • Proof of address or residency: some embassies additionally ask for proof that you live within their jurisdiction.
  • Proof of income or assets: not a statement based on trust, but actual bank statements or a bank letter showing the required amount.
  • Insurance policy and insurance certificate: besides the policy itself, the embassy asks for a separate certificate, completed and stamped by the insurer, confirming the coverage meets Thai requirements.

⚠️ This list is a general overview. Exactly which documents are needed, and in what form, differs per Thai embassy or consulate. Always check the current document list directly with the embassy where you’re applying.

The annual renewal must be done in person at a Thai immigration office. Plan at least one visit per year for this, even if you spend most of the year elsewhere. If you stay in Thailand continuously for more than 90 days at a time, you must also report your address to immigration every 90 days (TM47). The count restarts with every new entry.

⚠️ Not the same as the DTV: the Destination Thailand Visa (DTV) also offers stays of up to 180 days per entry, which at first glance makes it seem like an alternative for part-year retirement stays. It isn’t. The DTV requires remote work for a foreign employer, freelance income, or participation in a specific cultural activity (such as Muay Thai, cooking courses, or medical treatment). This visa isn’t meant for general retirement or leisure stays. If you don’t work and don’t fall into one of these categories, the O-A visa applies to your situation, not the DTV.

💡 Note on tax residency: the same 180-day threshold that applies to DTV holders (see above) applies here too. If you stay 180 days or more in Thailand per calendar year, regardless of which visa you hold, you become a Thai tax resident. This can affect how foreign income is treated. Keep this in mind if your stay is close to this threshold.

Common questions

Do I have to stay in Thailand the whole year with a retirement visa?

No. The O-A visa allows multiple entries, so you can stay part of the year, leave, and freely return within the visa’s validity, as long as you renew it annually in Thailand. If you stay continuously for more than 90 days at a time, the 90-day address notification also applies.

Can I get a Thai retirement visa if I’m not married?

Yes. The O-A is based solely on age (50+) and financial requirements. There’s no marriage requirement.

What visa do I need to overwinter in Thailand for 6 months a year?

For most people over 50, the Non-Immigrant O-A visa is the right choice. This visa isn’t tied to work, freelancing, or cultural activities, as is the case with the DTV.

Can I use my state pension or foreign pension as proof of income?

In principle yes, but income verification letters from embassies have become far less common. Several embassies in Bangkok have stopped issuing them, so most applicants now show proof directly through bank statements, either the required THB 800,000 balance equivalent, or a monthly income of at least THB 65,000. Always confirm with your own embassy, or the immigration office handling your application, what’s currently accepted.

Note: this only applies to the income method. If you use the THB 800,000 deposit method instead, a bank balance is exactly what’s required. Only under the income method does a balance or savings not count on its own, it has to be a demonstrable income.

Can I overwinter on a tourist visa instead of the O-A visa?

Visa-exempt entry is currently limited to 30 days. With a Tourist Visa (TR) you can stay 60 days, with the possibility of a 1-month extension, for a maximum of 90 days total. That’s not enough for a continuous stay of around 180 days, even with the extension. The O-A visa remains the most suitable route for that.

Destination Thailand Visa (DTV)

Launched July 2024, the DTV (Destination Thailand Visa) offers a multi-entry, long-stay option ideal for digital nomads, freelancers, remote workers, and professionals working outside Thailand.

Key Benefits & Limitations:

  • Validity: 5 years with multiple entries.
  • Stay Duration: Up to 180 days per entry, extendable once per entry for an additional 180 days (i.e. up to ~360 days without leaving).
  • Visa Fee: THB 10,000 per entry or extension.
  • Eligible Activities: Remote work for foreign companies, participation in Thai cultural activities (e.g., Muay Thai, cooking classes), medical treatments, seminars, and more.
  • Work restrictions: You cannot obtain a Thai work permit or work for Thai clients; allowed to work for overseas companies or run online business remotely
  • Dependents: Legal spouses and children under 20 can accompany the primary visa holder.

Requirements:

  • Age: Applicants must be at least 20 years old.
  • Financial Proof: Evidence of funds totaling at least THB 500,000, held in the account for at least 3 months before applying. A single large deposit made shortly before applying is a common reason for rejection.
  • Documentation: Depending on the purpose, documents may include proof of freelance / remote work or business outside Thailand (portfolio, contract, income statements), employment letters, enrollment confirmations for cultural activities, or proof of relationship for dependents.
  • Application location (new, 31 August 2026): You must apply at the Thai embassy or consulate covering your country of citizenship or your country of legal permanent residence.
  • Criminal record check (new, 31 August 2026): A criminal record clearance certificate from your home country is now required.
  • Soft Power activities: Thai language school enrollment no longer qualifies. Choose from other eligible Thai cultural activities (e.g. Muay Thai, cooking classes) instead.
  • Reporting: Most non-immigrant visa holders and long-stay residents must report their current address to Thai immigration every 90 days. This is known as 90-day reporting and applies even if you haven’t moved.

⚠️ Tax note: Spending 180 days or more in Thailand within a calendar year makes you a Thai tax resident, which can affect how foreign-sourced income is treated. This is a common surprise for long-stay DTV holders. Consider speaking with a tax advisor if you’re planning to stay near or beyond that threshold.

When DTV is a good choice

If your main goal is long-stay with remote work freedom (but without employment in Thailand), DTV is a strong option, especially compared to constantly renewing tourist visas.

When DTV is not ideal

If you want to work for Thai companies or pursue permanent residency/work permit, options like LTR or Non‑Immigrant B / Work Visa might be more suitable.

Application Process:

  1. Visit the 🔗 Thai e-Visa Portal.
  2. Complete the online application form.
  3. Upload required documents.
  4. Pay the visa fee.
  5. Await approval notification.

Don’t forget to complete your TDAC (Thailand Digital Arrival Card) within 72 hours before departure.

For the most current information and to apply, please refer to the official Thai e-Visa Portal.

Long-Term Resident (LTR) Visa

The Long-Term Resident (LTR) visa was introduced by the Thai government in 2022 to attract high-potential foreign residents, including wealthy individuals, skilled professionals, and remote workers. It allows approved applicants to stay in Thailand for up to 10 years and offers benefits such as annual immigration reporting instead of 90-day reporting, the possibility to include dependants, and certain tax and work-related advantages for qualifying applicants. Applications are handled by Thailand’s Board of Investment (BOI).  

The LTR visa has four main categories, each with its own detailed requirements:

  • Wealthy Global Citizens – high-net-worth individuals holding at least USD 1 million in global assets, including at least USD 500,000 invested in Thailand. No separate income requirement applies to this category.
  • Wealthy Pensioners – retirees aged 50+ who meet the required passive income thresholds, with alternative routes involving lower income plus investment in Thailand
  • Work-from-Thailand Professionals – remote workers employed by qualifying overseas companies who meet the relevant income and employment criteria
  • Highly-Skilled Professionals – specialists working in targeted sectors who may qualify for special tax and visa-related benefits under the scheme  

Because the financial and professional thresholds are significantly higher than for standard visa routes, the LTR visa is suitable for a relatively small group of applicants. Even so, eligibility has broadened over time, so it is worth checking the official BOI LTR website for the latest criteria if you think you may qualify.  

Marriage Visa (Non-Immigrant Visa “O” – Based on Thai Spouse)

This visa is for foreign nationals legally married to a Thai citizen, allowing for long-term stays in Thailand.

Eligibility:

  • Must be legally married to a Thai national.
  • Must meet financial requirements.
  • Eligible spouses include same-sex couples. Thailand’s Marriage Equality Act, in effect since January 2025, gives same-sex spouses legally married to a Thai citizen the same eligibility for this visa as any other spouse.

Key Features:

  • Initial Visa: Typically valid for 90 days; can be extended to a 1-year stay based on marriage.
  • Extensions: 1-year extensions can be applied for annually at local immigration offices.
  • Work Eligibility: Holders can apply for a work permit.

Financial Requirements:

  • Option 1: Bank deposit of at least THB 400,000 in a Thai bank account for at least 2 months prior to application.
  • Option 2: Monthly income of at least THB 40,000, verified through pay slips.

Required Documents:

  • Valid passport.
  • Marriage certificate (original and copy).
  • Thai spouse’s ID card and house registration (Tabien Baan).
  • Proof of financial means (bank statements or income evidence).
  • Photos of the couple together at home and in the community.
  • Map to residence in Thailand.
  • For the e-Visa portal, applicants may be asked to provide proof they are outside Thailand at the time of application.

Application Process:

  1. Apply for the visa at the Thai e-Visa portal. You can only do this when you are not in Thailand. The visa you will receive will be valid for 90 days.
  2. For an extension of stay (typically up to a year), submit required documents to the local immigration office.
  3. Attend an interview with your Thai spouse.
  4. Await approval and receive the extension stamp.

ℹ️ Note: Regular 90-day reporting to Thai immigration is required. Late reporting and/or overstaying can lead to penalties.

⚠️ Bangkok Bank customers: Bangkok Bank has confirmed that, under its current policy, foreign customers requesting a deposit balance certification letter for a marriage visa are required to have THB 400,000 frozen for four months. During this period, the frozen amount cannot be withdrawn. This is a Bangkok Bank policy rather than a Thai Immigration requirement; for example, Kasikorn Bank does not currently impose the same four-month freeze. Bank policies can change, so check the conditions with your bank before requesting the letter.

Non-Immigrant Visa “B” (Business & Employment)

For individuals employed by or doing business with Thai companies. In most cases, a Thai employer must sponsor the visa and work permit application process on behalf of the expat.

Since the September 2026 visa exemption reform, entering Thailand visa-free no longer covers business meetings or short-term work of any kind. Anyone planning business or paid activity in Thailand should arrange a Non-Immigrant “B” visa before travel rather than relying on visa-exempt entry.

Requirements:

  • Valid passport
  • Completed visa application form
  • TDAC QR code
  • Passport photo
  • Letter of employment or business invitation
  • Company registration documents

More details: Non-Immigrant B visa on the Ministry of Foreign Affairs website

For visiting family, medical treatment, or volunteering.

Requirements:

  • TDAC QR code
  • Valid passport
  • Visa application form

Extensions of Stay

  • Tourist / visa-exempt entry: Usually extendable by 30 days at immigration for THB 1,900.
  • Non-immigrant visas (including retirement and marriage): Extension rules vary by visa type, but many allow extensions of up to 1 year.
    • Marriage visa: In practice, extensions are often processed in stages, with a short initial extension during review, followed by a longer extension once approved.
  • How to apply: Visit your local immigration office (for example Chaeng Wattana, Chiang Mai, or Phuket), arrive early, and bring all required documents

What to Expect at Immigration

When arriving in Thailand, immigration officers may check the following:

  • Passport & visa stamp
  • TDAC QR code
  • Proof of onward or return travel
  • Accommodation details (hotel booking or host address)
  • Proof of sufficient funds (cash, bank statement, or credit card; checks are discretionary)

Arrival at Airports

Major international airports such as Suvarnabhumi Airport (Bangkok) and Phuket are generally efficient, though queues can be longer during peak arrival periods.

Some airports offer automated immigration gates for travelers who are eligible for them. At Suvarnabhumi Airport (Bangkok), e-gates are now available to travelers from 33 nationalities entering under visa exemption only: Australia, Austria, Belgium, Canada, Czech Republic, Denmark, Finland, France, Germany, Greece, Hong Kong, Hungary, Ireland, Italy, Japan, Latvia, Luxembourg, Malaysia, Malta, Netherlands, New Zealand, Norway, Poland, Portugal, Singapore, Slovakia, Slovenia, South Korea, Spain, Sweden, Switzerland, UAE, and the UK. This covers only about half of EU member states (not all 27), alongside several Asia-Pacific and Gulf nationalities, so confirm current eligibility before you travel, as the rollout is happening in phases. If you’re entering on any visa, including a DTV, you’ll still go through a staffed counter regardless of nationality. You’ll also need a completed TDAC and a prior Thailand entry on the same passport with biometrics on file; first-time arrivals always use a staffed counter too.

If you are arriving at Bangkok’s main international gateway, see our detailed Suvarnabhumi Airport (BKK) arrival guide for step-by-step information on immigration procedures, airport transport into the city, SIM cards, money exchange, and airport services. The guide also explains when fast-track immigration options may be available.

Arrival at Land Borders

Land border crossings may involve additional scrutiny. Under the September 2026 rules, visa-exempt travellers can generally enter Thailand by land no more than twice per calendar year, so border runs are no longer a practical way to extend a stay.

Cambodian and Myanmar nationals entering under their bilateral agreements receive 14 days, at international airports only. All land crossings between Thailand and Cambodia remain closed.

Insider Tips

  • Always double-check the stay-until date stamped in your passport by immigration; it’s the date that legally matters, not what you calculated yourself.
  • Coming and going overland, for example from Malaysia or Laos? Count your visa-exempt land entries for the calendar year before you book. The current rules allow two per year.
  • Have your accommodation address ready even if you’re entering visa-exempt; immigration officers can ask for it at the border, not just for visa-on-arrival.
  • For extensions, arriving at Immigration early (around 8 AM) cuts your wait significantly compared to midday.
