They tend to provide a polite warning first, unless abuse is clear and obvious - the ETA can’t come soon enough will put people’s minds at rest before they travel and eliminate all the so called “scaremongering”
they were very simple, 30 day visa exemption extendable by 30 days, for 1900 baht , once only…..more than adequate for tourists. however in order to stimulate travel to Thailand after Pandemic, they extended the visa exemption to 60 days and added many countries, this was extendable by 30 days……..unfortunately widely abused by long stay visitors , especially Russians and Chinese so they have announced that these short term measures will be canceled, and back to 30 day exemption, tourists aren’t impacted, but ‘long term’ visitors (incl retirees) intent on gaming the system are less than impressed, and being forced to leave or get the correct visas which requires funds to support themselves…….. not unreasonable.
The name of the account is SCB Easi Pass, comes without a pass book, and a very user friendly online app, there is a small one page book which immig accept for visa renewal, but not the traditional passbook you update….very user friendly, made the switch 4 years ago……
