Last year I applied to extend my Married to Thai one year visa with the appropriate mountain of paperwork and "she who must be obeyed" with me. at Samui Immigration. Everything was fine until the Officer in the right hand Office said, "you havn't deposited any money in your Bank today!" I had already deposited the mandatory 40,000 baht for that month, which was recorded both in my Bank Book and the Bank Letter, but she said that was not good enough. I was about to blow a fuse, but my lovely calm Thai Wife said, "go have a coffee and I will be back in 15 minutes". Which she was and the application was accepted by the Officer behind the desk.
My view is this was an attempt for us to pay extra for the Visa, which I refuse to do. I think next time I will refer the case to Bangkok Immigration for advice?
