Always verify before you fly. Visa rules change frequently.
Confirm the current requirements for your nationality with the Royal Thai Embassy or the official
e-Visa portal well before departure.
Visa-exempt entry
Passport holders from many countries may enter Thailand without a visa for short tourist stays. Whether this applies to you — and for how many days — depends on your nationality and current Thai immigration policy.
Thailand e-Visa
If you need a visa, the simplest route is the official Thailand e-Visa at thaievisa.go.th. You will typically need a passport valid for at least six months, a recent photograph, proof of accommodation and onward travel, and the visa fee.
Letter of invitation
Registered delegates can request an official letter of invitation to support their visa application. Contact the Secretariat →
