"Even mentions doing them at police station.."
Well going back quite a few years I was sure an expat friend talked about doing it a police station.
The mariage visa definitely seems the way to go. I could opt not to draw so much down on the private penion and/or invested savings leaving more in the pot for a rainy day. I was concerned about draining more than I actually need then leaving it senselessly sitting in a Thai current account.
My wife is a nurse so has a pretty good salary, for a Thai.
In fact if I can go off topic again, my wife works for a Government hospital. I understand as a spouse of a Government employee I am entitled to health care in Thailand. Anybody else married to a Thai Government employee can confirm this?
