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!
