Was just thinking about the advantages of marrying a Thai.
I get tax allowances for being married, also for my wife's parents who are over 60.
Used to be easier for your kids if the parents are married, but not now.
The only advantage for older, retired guys is less money in the bank for a visa, however the disadvantages FAR outweigh this advantage. After living here for 30 years, I could tell you about billions of baht lost due to foreign guys trusting their wives.
There is one other advantage, if you go down to the town house and spend hours and time getting a yellow housebook(that foreigners call 'tabien bahn'), you can get a pink card that means you don't have to carry your passport every 5 years when you renew your Driver's license except in a few provinces, like Roi Et included.
