Hello everyone! A few days ago I received my first one-year Extension of Stay Permit (EOS) from my immigration office. I had my salary certificate certified by my embassy in Bangkok. My immigration told me that I actually have to have this certified certificate certified again in Bangkok by a Thai authority. (over-authentication).
What is the name of this authority in Bangkok?
And where is this authority located?
Because it is my first EOS, my immigration has kindly stamped the EOS in my passport without this additional authentication just for this time.
Thank you for your answers!
TLDR : Answer Summary
The post discusses obtaining a one-year Extension of Stay Permit (EOS) in Thailand and the requirement for additional document certification. The user needs to know the authority responsible for certifying their salary certificate in Bangkok, which is likely the Ministry of Foreign Affairs or the Department of Consular Affairs. Key locations mentioned include Central World and Chaeng Wattana, and it's recommended to make an online appointment for the process.
