Just got my 30 days extension for TR60 visa in Muang Thong Thani.
They only asked copy of passport and TM6, forms, pictures, and the 1900 bath.
I had appointment but I didnโt really need - it was just me and a few guys, very quick
It closes from 12pm to 1pm.
Thanks admins and mods in the group for the info!
