Apparently this formidable additional expense will come into effect in July (2019).
To be processed at the time of applying for a one-year visa.
Looking at the "approved" health insurance providers, premiums will quickly escalate from about Bt 50,000 a year for a 50 year old to Bt 250,000 a year for those in their 90s.
For myself this is outrageously more than I currently pay for non-subsidised care at a local hospital.
It is also difficult to believe that authorities have found this measure necessary due to foreigners dodging hospital bills; my experience is that hospitals demand a credit card before they will even see you. (never understood how that stands up against medical ethics)
Does anyone have an opinion on how this will hit foreign retirees?
Knowledge of how authorities consulted foreigners for this would also be interesting?
