so the people who died of what you call fake flu.. exactly what did they die of. And if it was fake how come all of the doctors pharmacists etc were fooled??
in that case take the house book to immigration indicate you live there. They give you a form to take to bank..500 baht I think...go to Bangkok Bank....take out their accident insurance...get bank account in minutes
I have spoken to many expats who tell me they have had great care in hospitals in Thailand. I am here not had any health issues yet. No one is going to stop your visa because of ill health
