I'm on a non O visa based on over 50 (retirement) Currently I use the 800,000 in a Thai bank (rotting away) method and I'm looking at changing to the 65k monthly income method. I currently use wise to transfer my 'monthly income' to my thai account from the UK.

Couple of questions. Is wise acceptable for the transaction being considered an international transfer? If so do you have to select a particular 'reason for transfer' when making the wise transfer? e.g. 'Funds for long term stay in Thailand'

Living in Phuket if that makes any difference, I know how fickle different immigration office's can be.
