Travelers wishing to enter Thailand have two options: through an airport or overland. Regardless of the mode of entry, the same rules apply to all travelers.
As of July 2024, there are now 93 countries whose citizens can enter without a visa for periods up to 60 days as a tourist. These entries can also be extended once for an additional 30 days. (previously it was 64 countries & 30 day stays) You can find the full list of countries eligible for visa free entry here.
An expanded list of 31 countries can now apply for a Visa on Arrival for stays up to 15 days. The Visa on Arrival entries can not be extended. You can find the updated list of VOA eligible countries here.
Single Entry Tourist Visas (Type TR) allow stays of up to 60 days and are available to all nationalities. The tourist visa can also be extended once for an additional 30 days. These tourist visas are for citizens of countries that do not qualify for visa-free entry.
To comply with the rules, travelers entering visa-free or applying for a VOA must present an airline ticket that departs Thailand before their initial entry period ends (60 and 15 days, respectively). Other travelers may also be asked by the airline to show proof of a departing flight.
When applying for a VOA, travelers must be able to demonstrate that they have 10,000 THB for an individual or 20,000 THB for a family. For those entering visa-free or with a Tourist or Non-Immigrant visa, proof of financial ability must be shown in the form of 20,000 THB and 40,000 THB, respectively. It's important to note that cash is the only acceptable form of proof of financial ability, and credit cards or bank statements do not count. Any major currency is equivalent is acceptable.
Although the majority of travelers are not asked to show proof of financial ability, some travelers may occasionally be asked to do so at Immigration. Therefore, travelers should always be prepared to provide evidence of their financial ability.
Citizens of most countries can apply for a Thai tourist visa at the official Thai government website here.
If your country is not eligible for online applications, then visas must be applied for through the nearest Royal Thai Embassy or Consulate.
