correct, and in that case the money is always put into account within Thailand and it doesn't need to be marked FTT. At least my deposits never came from abroad.
Sorry, since the "initial Visa" is usually applied for in your home country, i can't really believe that. In my understanding ONLY the income method needs to be marked FTT in your bank book.
1st year you need the 800k. If you have all the 12 month an income from abroad into your Thai bank account of minimum 65k THB, you can use that from 2nd year onwards.
Every Bank branch can give you a statement for the last 6 months. Statements for 12 months they have to order from Bangkok Headquarters. However, many branches will refuse any service and gonna tell you to visit your home branch.
