There are many different types of visas you can get, depending on how long you want to stay and other conditions. Sometimes, a visa is not even necessary. Here some quick facts:
 

Where to issue visas


Visas are issued at the Royal Thai Embassy or at the Thai Consulate of your country and can be collected on-the-spot. Depending on the type of visa, they may be extended to a longer period of time. For your visa to be issued, you need several documents:

No Visa - 30 days
It is issued to most nationalities upon entry into the Kingdom and can be extended, before it expires, for another 14 days at an Immigration Office. The fee is around 1,900 Baht and overstay fines are 500 Baht per day. This visa will be re-issued every time you leave and re-enter the Kingdom.

Tourist Visa - 60 days
This visa is issued in any country other than Thailand at the Royal Thai Embassy or at the Thai Consulate. It can be extended for 30 days at your nearest Immigration Office.

Overstay


Overstay fines are 500 Baht per day, with a maximum of 20,000 Baht. The fine has to be paid on your departure or when you ask for an extension. If you get caught for overstaying or can not pay the fine when leaving the country, you run the risk of being sentenced to up to 2 years of imprisonment. Note that overstays can also jeopardize your future applications.
