it's NOT a sticker visa anymore ๐ (you got yours before what ever consulate you used switched to the eVisa online system
Now every thai consulate in the world went to online eVisa web portal ๐ฎ
There are no walk up apply consulates. ๐
You go to the country whose consulate you want to apply at, you log in to the eVisa system, upload your required documents, proof you're in that country (visa/entry stamp) pay and wait for the visa to be approved and they send it to you by email
