The government will extend the visa waiver fee for visa on arrival by another six months (untill April 2020) to increase the number of foreign tourists in the kingdom.
Here is a short summery of the Visa Fees for a Thai Visa in Euro, USD, GBP & SEK. I have taken the numbers from selected Thai Embassies in Europe and the US.
The Visa Fees are usually set in Thai Baht first and then being converted into the other currencies. Basically, the prices for the Thai Visas are more or less the same all over the world, when you convert them back into Thai Baht.
