Please note that the period of Thailand visa validity is different from the period of stay.
Thai Visa validity is the period during which a visa can be used to enter Thailand.
In general, the validity of a visa is 3 months, but in some cases, visas may be issued to be valid for 6 months, 1 year or 3 years.
The validity of a Thailand visa for Indians is granted with discretion by the Royal Thai Consulate-General and is displayed on the visa sticker.
The period of stay is granted by the Thailand immigration officer upon arrival at the port of entry and in accordance with the type of visa.
For example, the period of stay for a transit visa should not exceed 30 days, for a Thai tourist visa should not exceed 60 days and for a non-immigrant visa should not exceed 90 days from the arrival date.
The period of stay granted by the immigration officer is displayed on the arrival stamp.
Travellers who wish to stay longer than such period may apply for extension of stay at offices of the Immigration Bureau in Bangkok, located at Soi Suan Plu, South Sathorn Road, Bangkok 10120, Tel 02-2873101-10 or at an Immigration office located in the provinces.
