Visiting Thailand as a Tourist
When you visit Thailand for the purpose of leisure, sight-seeing and personal enlightenment, you are a tourist. A tourist is not allowed to work or conduct business in Thailand. A tourist needs a tourist visa so you can stay in Thailand for a period of 15 or 30 days while doing her own explorations and excursions in the kingdom.
A tourist visa is a stamp or document needed so you can stay in Thailand for a specific period of time, on the purpose of tourism. It is stamped on your passport upon arrival at the airport in Thailand, or it can be obtained in your home country through the Thai embassy or consulate located there. The tourist visa can also be extended if necessary. There are certain countries who made agreements with the government of Thailand so their citizens can benefit from the visa exemption when entering Thailand as tourists.
