Thailand entry requirements

By the Viamo editorial team · Editor Terje Moy · Last updated July 2026 · 5 min read

Thailand is one of Southeast Asia's most visited countries, and its entry rules have evolved considerably in recent years. Many nationalities can arrive without a visa for short stays, while others need a visa arranged in advance or available on arrival. The picture changes regularly, so this guide explains how the system works — but always confirm the current rules for your passport with official sources before you travel.

Visa exemptions for short stays

Citizens of many countries — including the UK, most EU and EEA states, the US, Canada, Australia and a large number of others — have historically been able to enter Thailand without a visa for stays of up to 30 days when arriving by air, or for shorter periods at land borders. Thailand has at various times extended this period to 60 days for some nationalities, particularly to boost tourism.

The precise duration and the list of eligible countries does change, so do not assume the exemption period you used on a previous trip still applies. Check the Thai Ministry of Foreign Affairs or your nearest Thai embassy or consulate for the current situation.

Visa on arrival

For nationalities not covered by a full exemption, Thailand offers a visa on arrival (VOA) at major international airports and some land borders. It typically allows a stay of around 15 days and requires a fee payable in cash (Thai baht or sometimes USD). Queues at the VOA desk at Suvarnabhumi in Bangkok can be very long at peak times; having the required documents ready — including a passport photo, onward ticket and proof of funds — speeds the process up.

Tourist visa (TR) arranged in advance

If you want to stay longer than the exemption or VOA allows, or if your nationality is not eligible for either, you can apply for a tourist visa (TR) at a Thai embassy or consulate before you travel. A single-entry tourist visa typically allows a stay of up to 60 days and can be extended once at a local immigration office inside Thailand. A double-entry version is also available.

Thailand also introduced a longer-stay Long-Term Resident (LTR) visa aimed at retirees, remote workers and certain investors — this is a more involved process but gives multi-year stays for eligible applicants.

Thailand e-Visa

Thailand has progressively rolled out an e-visa system, allowing applicants from many countries to apply online and receive their visa electronically rather than visiting a consulate in person. Availability varies by country and visa type — check the official Thai e-Visa portal for your nationality. The process requires a passport scan, photo, proof of travel and payment by card.

What to carry when you arrive

Regardless of how you enter, Thai immigration officers may ask to see:

• Your passport, valid for at least six months beyond your intended departure date
• A confirmed onward or return ticket leaving Thailand before your permitted stay expires
• Proof of accommodation for your first night (hotel booking or contact address)
• Evidence of sufficient funds — the informal rule of thumb has been around 10,000 baht per person, though the actual requirement is at the officer's discretion

Travellers who arrive without a confirmed onward ticket have occasionally been denied entry, particularly at land borders. Having evidence of onward travel is strongly advised.

Land border crossings

Thailand shares land borders with Myanmar, Laos, Cambodia and Malaysia. Exemption and visa rules at land borders have historically been more restricted than at international airports — the permitted stay has sometimes been shorter, and some crossings apply a limit on the number of visa-exempt entries per year. "Border runs" — crossing out briefly and re-entering to reset a stay — have become more tightly policed over the years; immigration officers may refuse entry or question travellers who have made many recent entries. If you are planning an extended stay, a proper visa is a far more reliable solution.

Health and other entry requirements

Thailand dropped its COVID-related entry requirements some time ago, but it is always worth checking whether any health documentation is required at the time you travel. Travellers to some islands may pass through informal health or ferry checks, though these are not generally official entry requirements.

Frequently asked questions

Do I need a visa to visit Thailand?

It depends on your nationality and how long you plan to stay. Many nationalities receive a visa exemption for short stays on arrival, while others need a visa on arrival or a visa arranged in advance. Check the current rules for your passport with your government's travel advice and the Thai Ministry of Foreign Affairs.

How long can I stay in Thailand without a visa?

The visa-exempt period has varied between 15 and 60 days for different nationalities and different time periods. The current allowance for your passport should be confirmed with official sources, as it changes and differs between air and land arrivals.

Can I extend my stay inside Thailand?

Yes. Tourist visas and some visa-exempt stays can be extended at a local immigration office inside Thailand for an additional fee. The extension period and process depends on your visa type — check with the nearest immigration office or a reputable local agent.

Is a land border crossing a reliable way to reset my stay?

Less so than it once was. Thai immigration has tightened its approach to frequent border crossings, and travellers using land borders regularly to extend stays may be questioned or denied entry. For longer stays, applying for an appropriate visa in advance is strongly recommended.
