Transit Visa for Thailand

You would not need a visa to transit Thailand, when you're making a connection of not more than 12 hours. For a long period, such as a two-day visit, you would need to secure a transit visa in advance.

From Thailand's Ministry of Foreign Affairs

Validity of Visa
The validity of visa, as indicated on the visa page (“Enter before …”), is the length of time during which the holder of the visa is entitled to present himself/herself at a Thai immigration checkpoint with a view to entering into the Kingdom of Thailand. It does not indicate the length of time the holder of the visa may stay in the Kingdom. The validity of a single entry Transit Visa is 3 months from date of issuance and that of a two-entry, three-entry or four-entry Transit Visa may be 3 or 6 months from date of issuance.

Period of Stay
The period of stay in the Kingdom of Thailand is not to be confused with the validity of the visa. While the latter is indicated on the visa page, the period of stay (or each stay for a two-entry, three-entry or four-entry Transit Visa) will be determined upon arrival at a Thai immigration checkpoint by the immigration officer (“Admitted Until …” stamped on passport page). Holders of a Transit Visa may be granted entry and permitted to stay in the Kingdom at the discretion of the immigration officer for a period not exceeding 30 days.

Transit Passengers
Passengers transiting at an airport in the Kingdom with a view to catching a scheduled connecting flight within 12 hours of their arrival without the intention of clearing immigration procedure, do not require a visa. They must however be inspected by the competent authorities upon arrival and must stay only in designated areas of the airport until their departure. All passengers transiting at an airport in the Kingdom for more than 12 hours must obtain a transit visa prior to their arrival.
