YOU MUST IMMERSE YOUR AUTHORITIES IN YOUR COUNTRY ON THE CONDITIONS OF VALIDITY OF YOUR PASSPORT.
Everyone entering Thailand must be in possession of a current passport, and it must be valid for at least six months from your date of entry.
Thailand has visa-on-arrival and visa-exemption agreements with most a lot of nations, including European countries, Britain, Australia, New Zealand, Canada, and the USA. Depending on your nationality, you are issued a 14 to 90-day visa exemption and all without any charge. Without proof of a ticket out of the country, you can, in theory, be denied entry. Remember that there are frequent modifications made to the visa regulations, so check the website of the Thai embassy in your country or online at the Ministry of Foreign Affairs in Thailand.
