Visas and Passports
Travellers should check visa regulations at a Thai Embassy or consulate before staring their journey. All foreign nationals entering Thailand must have valid passports. At the airport, nationals from most countries will be granted a free transit visa valid up to 30 days, provided that they have a fully paid ticket out of Thailand. Tourist visas allow for a 60-day stay from the date of entry into the Kingdom. People who are waiting for a work permit to be issued can apply for a non-immigrant visa, which is good for 90 days, from their Thai Embassy or consulate at home. A letter of guarantee is needed from the Thai company you intend to work for.

Visa Extensions
Visas can be extended before they expire by applying at the Immigration Bureau on Soi Suan Plu, South Sathorn Road, Tel : 0 2286 4231, 0 2287 3101 ext. 2271 (8:30 a.m.-4p.m., Monday-Friday) Visitors wishing to leave Thailand and return before their visa have expired can apply for re-entry permit prior to their departure at immigration offices.

Banks

If you have overseas business to conduct with a bank, it is better to do it in Bangkok. Most banks are open from Monday to Friday at 8:30 a.m - 3:30 p.m.

Money Matters
The Baht is the principal Thai monetary unit. It is divided into 100 units called satang. Bank note denominations include 1,000 (grey), 500 (purple), 100(red), 50(blue), 20(green), 10(brown) baht. While bank notes are easy to decipher, the coinage is a confusing matter with a variety of sizes and types for each denomination. Ther are 10-baht coin (brass center with a silver rim), two different 5-baht coins (silver pieces with copper rim), three varieties of 1-baht coins (silver, usually only the small size will fit in a public telephone), and two small coins of 50 and 25 satang (both are brass coloured).
