Tell him that you have now another 3 friends coming to Thailand and that they need the Visa, too. But he must give you all a discount. He will give you and you ask for the time to talk with your friends. And do not call him anymore. If he will call you tell him that you are waiting their answer and you will call him back ( thai way to send you to hell ). Do not call him. He will start to understand that his dream to make easy money robbing you and much more money with your friends is really a dream.
up to now Immigration did not call me and I will need to go for the marriage visa within 2 weeks. If they should call me asking to show them again that I still have 400k it should be possible but they cannot do this. They should have told me when they started my consideration or they should have written in their website. There is no logic, at least western logic. I will inform the Group after day 3 june, if they will ask me again or not.
