Well I would rather belive the embassy than all this on Facebook. Having travelled to Thailand for the last 30 years I have found the rules on the London Embassy to be correct.
If you want the transfer for your retirement extension. You transfer for longstay in Thailand. It will then take 2 working days.It will then appear in your thai bank account as an overseas transfer for visaa applications.If you select for tourism it is almost instant transfer but is not correct for visa applications ie
