You can buy the 60 day SETV visa for ฿1,900 In Malaysia then get it extended in Thailand at your local immigration office for 30 days at a cost of ฿1,900….I’m guessing this is the type of visa you want to buy
I took me 1 week to get my METV, it goes live the moment you receive the visa, so its important to buy your ticket to thailand asap so you can maximize the METV
do a border bounce before 04 JUL then go to your local immigration office and buy the 30 day extension for 1,900 THB to get 9 months out of the 6 month METV
