Do I need a visa?

Generally, foreign nationals wishing to enter Thailand are required to obtain a visa from the Royal Thai Embassy or the Royal Thai Consulate-General. However, certain nationals are eligible for visa exemption or visa on arrival. For online VOA please visit https://thailandevoa.vfsevisa.com/thailand/online/home/index

Foreign nationals entering Thailand on the Tourist Visa Exemption Scheme (30 days) may enter Thailand via land border only up to 2 times per calendar year (This limit does not apply to nationals of Malaysia, Brunei, Indonesia, and Singapore). There is no limit on the number of entries by air arrival

Foreign nationals entering Thailand on the Tourist Visa Exemption scheme and the Exemption from Bilateral Agreement are advised to prepare  proof of adequate finances for the duration of stay in Thailand to present at the port of entry (i.e., traveler’s cheque or cash equivalent to 10,000 Baht per person and 20,000 Baht per family) as well as proof of accommodation for the duration of stay in Thailand. 

Foreign nationals entering Thailand by any means on the Tourist Visa Exemption scheme and the Exemption from Bilateral Agreement are required at the port of entry to present  proof of onward travel (confirmed air, train, bus or boat tickets) to leave Thailand. Otherwise a tourist visa must be obtained before entering Thailand.
