When I transferred my visa to my new passport recently there was no mention of a letter. All immigration wanted was the old and new passport. They have all your details on the computer system.
You are right in telling her to save her money on paying agents fees if she has the 800k. When I got my retirement extension I entered on a 30 day exemption and converted it to a Non B at the immigration office and waited for the 2 month seeding period for the 800k and then converted to a Non O and then the yearly extension. I never had to leave the country. It cost me a total of around 4,000 baht for the 2 visas. It was very straightforward and easy to do by myself. I don't understand why so many people are telling you to use an agent.
you never have to use an agent. I did all of that myself. From 30 day entry converted to Non B then Non O and one year extension all without leaving the country. 2,000 baht
I can show you insane strategies that will make huge sums of money on demo or back test but there's no way you would sleep at night on a live account or even take the trades when your own money is on the table.
do you seriously think that practicing on a demo account is the same as a real account? Trading is 10% strategy and 90% psychology. So do you think there is the same psychology in play on a demo account as there is on a live account?
