ATTENTION BANGKOK MEMBERS ONLY
Anyone who entered the country on a 60 day tourist visa OR a Special tourist visa (no matter when that was) now uses Chaengwattana for your extensions starting on Monday April 5th.
This means IF you used Counter J at MTT to get an extension and have an under consideration stamp you need to return to 'close the loop' on you go to Chaengwattana NOT Muang Thong Thani.
This also has NOTHING to do with anyone else or any other section. Only people who have a tourist VISA or a Special Tourist visa and/or extensions from those are affected.
Thanx Ellie Takei for posting it (y)
