Greetings Everyone
There are many people asking about visa here.
Thailand has many types of visa - education; employment; retirement; business; religious etc
Visa fees are different for different countries and duration of visa too
Contact the Thai embassy at your own country for they will give you accurate answers.
Always listen from the horse mouth when comes to official matters so as there is no mistake.
Good example, ASEAN countries people don't need to pay any fees for tourist or business visa but other countries do and different price too. Europe has Euro and Thailand is member of ASEAN.
