Nik Dadd It might be different for married to a Thai visa. There was an order from Immigration or Royal Thai Police relating to the special circumstances for US, UK and Australia. Suggest you seek out Tod Daniels in this group who *might* have a copy of this. His knowledge of visas is pretty well unsurpassed.
Nik Dadd Immigration allow it for citizens of Australia, UK and USA, as these embassies no longer provide affidavits of income, so transfers actually have to be made into a Thai bank account at monthly intervals and must be shown in the bank book as an international transfer
Nik Dadd I had to get a year's worth of bank statements from my bank which cost me 200 baht, plus the updated bank book. These had to show the 65k international transfer, one for each calendar month for the previous year.
