For most people, the first encounter with Thai immigration rules happens before they’ve even booked a flight: do I need a visa at all? The answer depends entirely on your passport, and in 2026 the rules around this are more fluid than they’ve been in years, with a significant policy change approved by the Thai Cabinet and moving through the process of taking legal effect.

This guide covers visa-exempt entry, Visa on Arrival, the Tourist Visa (TR), the extensions available for each, the new Thailand Digital Arrival Card, and what to do if your trip falls right in the middle of a rule change.

1. The three ways to enter Thailand as a visitor

Depending on your nationality, you’ll generally fall into one of three categories on arrival:

• Visa exemption — no visa needed in advance; you’re stamped in for a set number of days on arrival, based on bilateral or unilateral agreements between Thailand and your country
• Visa on Arrival (VOA) — a short-stay visa issued at the border itself, for nationalities not covered by visa exemption but eligible for this simpler route
• Tourist Visa (TR) — applied for in advance through Thailand’s e-Visa portal or an embassy, giving a longer initial stay than exemption or VOA typically allow

Which category applies to you is determined entirely by your passport’s nationality — it isn’t a choice you make freely if you’re eligible for exemption, though you can still choose to apply for a Tourist Visa instead if you want a longer stay than your exemption category offers.

2. Visa exemption: how it currently works

Visa exemption allows eligible nationalities to enter Thailand without applying for any visa in advance, receiving an entry stamp for a set number of days directly at immigration. As of mid-2026, prior to the pending policy change taking effect, the position has generally been:

• Most of the 93 eligible countries and territories: up to 60 days, a policy extension introduced in July 2024
• A number of nationalities under separate bilateral agreements (including China, under a mutual exemption arrangement, and several others): 30 days
• Myanmar: 14 days, limited to international airports
• Several nationalities with longstanding bilateral treaties (including Argentina, Brazil, Chile, Peru, and South Korea): 90 days, unaffected by the broader 2026 policy review

3. The 2026 policy change, explained

On 19 May 2026, Thailand’s Cabinet approved a package of changes reversing much of the 2024 liberalisation:

• The standard visa-exempt stay for roughly 54 countries reduces from 60 days to 30 days
• A new 15-day tier applies to three island nations: the Maldives, Mauritius, and Seychelles
• The Visa on Arrival list shrinks from 31 countries to just 4: Azerbaijan, Belarus, India, and Serbia
• India, only upgraded to the 60-day exemption list in February 2026, is particularly affected — moving to a 15-day Visa on Arrival under the new framework
• A two-entries-per-year cap on land border crossings is being reinstated for most nationalities

These changes take legal effect only once published in the Royal Gazette, with implementation generally following around 15 days after publication. Because the exact publication date has moved without much advance notice in similar past changes, the safest approach for anyone travelling soon is to plan around the shorter 30-day figure rather than assume the older 60-day allowance will still apply by the time you land.

4. Visa on Arrival (VOA)

For nationalities not covered by visa exemption, Visa on Arrival offers a short-stay option processed directly at the border:

• Maximum stay: 15 days
• Cost: 2,000 THB, payable in cash
• Cannot be extended in the same way a Tourist Visa can, and covers tourism purposes only
• Requirements: a passport photo, proof of onward travel, and proof of funds
• Under the 2026 changes, eligibility shrinks from 31 countries to just 4 (Azerbaijan, Belarus, India, Serbia) — anyone previously relying on VOA outside these four should plan to apply for a Tourist Visa in advance instead

5. The Tourist Visa (TR)

If you’re not covered by visa exemption, want a longer stay than exemption allows, or simply prefer certainty before you travel, the Tourist Visa (TR) is the standard route:

• Applied for in advance via Thailand’s official e-Visa portal (thaievisa.go.th) or at a Thai embassy/consulate
• A single-entry TR typically grants an initial 60-day stay
• Processing commonly takes 5–10 business days — apply at least 2–3 weeks before travel to allow margin
• Does not permit any work, including remote work or freelancing

6. Extending each entry type

Both visa-exempt entry and the Tourist Visa can be extended once, for 30 additional days, at any Thai immigration office, using form TM.7. This is a one-time allowance per entry — it can’t be extended a second time within the same trip.

7. The Thailand Digital Arrival Card (TDAC)

The TDAC replaced the old paper TM6 arrival card and is now mandatory for essentially all foreign nationals entering Thailand at participating ports, including all major international airports and most major land crossings. It must be completed online, through the official immigration portal, within 72 hours before arrival — submission is free of charge.

8. Proof of funds and onward travel

Regardless of entry category, Thai immigration can (and periodically does) ask for evidence of:

• Sufficient funds — commonly cited at 10,000 THB per person or 20,000 THB per family under older guidance, though newer embassy guidance in some contexts has referenced higher figures (20,000 THB per person / 40,000 THB per family) — carry documentation for the higher figure to be safe
• Onward or return travel — a confirmed booking showing you intend to leave Thailand within your permitted stay; a one-way ticket with no onward plan can raise questions at check-in or on arrival

These checks are applied inconsistently in practice — many travellers are never asked — but being unable to produce evidence when asked can result in boarding denial at your departure airport or complications on arrival in Thailand.

9. Land border entries and the entry-per-year cap

Under the 2026 policy changes, a cap of two visa-exempt land border entries per year is being reinstated for most nationalities. This specifically targets a long-standing pattern of repeated short “border run” entries used to maintain a continuous presence in Thailand without a formal long-stay visa. Anyone relying on this pattern should treat it as an increasingly unreliable long-term strategy, not a stable arrangement.

10. Choosing between visa-exempt entry and a Tourist Visa

If you’re eligible for both, the choice generally comes down to certainty vs simplicity:

• Visa-exempt entry is simpler — no advance application, just show up with your passport and TDAC completed — but the exact permitted days can be subject to policy changes like the one currently underway
• A Tourist Visa requires advance planning and a small fee, but locks in your permitted stay before you travel, removing any uncertainty around a policy change landing mid-trip-planning

For anyone with a trip planned during a period of known policy uncertainty (like the current 2026 transition), applying for a Tourist Visa in advance removes the guesswork entirely, rather than gambling on which rule will be in force by your arrival date.

11. What happens beyond the maximum stay

Once you’ve used your entry stamp and any available extension, your options are the same regardless of which category you entered under:

• Leave Thailand before your permitted stay expires
• Apply for a proper long-stay Non-Immigrant visa if you want to stay longer term, ideally arranged from outside Thailand in advance
• Overstay, which carries fines and, beyond 90 days, re-entry bans — not a viable planning strategy

12. Common mistakes

• Assuming the 60-day exemption still applies without checking current status, given the policy change actively underway through 2026.
• Forgetting the TDAC, then being delayed or held up on arrival because it wasn’t completed in advance.
• Booking a one-way ticket with no proof of onward travel, risking denied boarding at the departure airport.
• Assuming Visa on Arrival can be extended like a Tourist Visa — it cannot.
• Relying on repeated land border runs, unaware of the reinstated two-entries-per-year cap for most nationalities.
• Not checking whether your nationality falls under a separate bilateral treaty (China, South Korea, and others) rather than the general exemption scheme, and assuming the general policy change applies when it may not.

13. Frequently asked questions

14. Practical tips

• Check your specific nationality’s current status close to your travel date, not months in advance, given the pace of change in 2026.
• Complete your TDAC within the 72-hour window before arrival, not at the airport under time pressure.
• Carry evidence of funds and onward travel, even if you’re rarely asked — the cost of having it ready is nothing compared to the cost of not having it when asked.
• If your trip timing is uncertain relative to the policy change, consider a Tourist Visa for certainty rather than gambling on which rule applies when you land.
• Don’t build a long-term Thailand strategy around repeated border runs — if you’re planning to stay for months or years rather than weeks, look into the correct long-stay visa category instead.
