Just done mine again for the 4th time,,you just need the 400k in when you go to apply,then you go bk 30 days after to get the final stamp,can use the money after you apply no problem..no need to have it in 2 mths b4..
I got back from uk on 13th august..went to jomtien immigration and ask if i needed to do it..YES was the answer,no matter what,,same house re-entry stamp same address when done re-entry..no exceptions.
