'Do all Thai Embassies and consular offices around the world already use E-visa? I translated and pasted below from the Embassy website
Not yet. In order to try and evaluate the various aspects, the Thai Ministry of Foreign Affairs has, for now, chosen some pilot offices to test the E-visa.

The third group of Embassies to use the E-visa will be the Thai Embassy in Paris and London on June 17, 2019.
