apparently not to many people know but they do have a testing station at the airport for quick tests at thb550 I was told, a few friends used already who were caught out..
little or no work take the Thai Elite 5 years but if you are married you take the family TE worth 800K if you take a retirement visa you need to jump through hoops opening a bank account and depositing and maintaining 1.6 mill thb for 2 persons. the TE visa resets for 12 months everytime you enter and is hassle free so it would only cost you about 25,000 for 2 persons under family TE visa believe me it’s worth having my wife and i are from australia and had for 10 yrs now and if any hassles you ask TE to help
