I recently turned 50, and secured my first Non O retirement visa (3 months). Soon I need to apply for my first 12 month extension. Local expats here in Hua Hin tell me I need to get a 12 month statement for my account at Bangkok Bank (which takes a week to get). However, the official immigration documents say the the 800k only has to be in the account for 2 months prior to applying for the (first) 12 month extension. Is the 12 month bank statement actually necessary for first time retirement extension applications?
