Generally speaking, foreigners visiting Thailand for business, investment, study, medical treatment, or employment are required to apply for a Thai visa from a Royal Thai Embassy or Consulate-General. Foreigners must possess valid passports or similar documents and comply with the regulations contained in the Immigration Act B.E.2522 (1979) and its related provisions. Be aware that Thai visa requirements change from time to time and a Thai embassy can provide you with the most up to date Thailand visa information.
If you are planning a short holiday in Thailand you may not require a Thailand visa if you are citizen of one of the approximately 40 nations that qualify for a Thai visa waiver or Thai visa exemption. With evidence of onward/return travel, citizens of New Zealand, Australia, Canada, the USA, and most European nations may enter Thailand for up to 30 days without a Thai visa. These Thailand visa waivers are issued upon arrival in Thailand. Those entering Thailand by land may not receive a 30 day exemption however; the Thai visa waiver was reduced to 15 days for those entering by land after January 1, 2009.
If your citizenship does not qualify you for a Thailand visa waiver or if you are planning to stay in Thailand for longer than 15/30 days, you must apply for a Thai visa at an embassy or consulate outside of the Kingdom. Thai tourist visas are valid for 30 or 60 days, though visitors who plan to travel from Thailand to a neighboring country and then back to Thailand can apply for several consecutive 30 or 60 day Thai visas. At most, three Thai visas can be issued at one time, granting visitors either 30 or 60 days for each entry into Thailand (maximum 3x60 days, requiring visitors to leave within 60 days before beginning the next 60 day visa).
The penalty for overstaying your visa is typically 500B per day, with a 20,000B limit. Fines can be paid upon departure at the airport. If you've only overstayed one day, you may not have to pay any fine or you may have to pay 1,000 baht, depending on the current regulations. Children less than 14 years old who are traveling with a parent or guardian are not required to pay any fines for overstays.
You can avoid paying any overstay fines by visiting a Thai immigration office and requesting a Thai visa extension. The Bangkok immigration office near Sathorn Rd is the most popular (02-287-3101; Soi Suan Phlu, 9am-12pm/13:00-16.30 Mon-Fri, 9am-12pm Sat) and the Chiang Mai immigration office will also provide Thai visa extensions (05-320-1755-6; Th Mahidon; 8.30am-16.30pm Mon-Fri). The usual fee for a Thai visa extension is around 2000 Baht. Because the immigration offices can be very busy, getting a Thai visa extension may not be practical unless you believe you will overstay your Thai visa by more than 3 or 4 days. The length of the visa extension depends on the length of your prior Thai visa; typically 7 days extension for a 30 day visa waiver and up to 30 days extension for a 60 day visa.
Other Thai visas, such as non-immigrant, retirement, and student visas should be inquired about at your nearest embassy or consulate, or the Thai Ministry of Foreign Affairs at www.mfa.go.th.
