: As with most things in Thailand, there is a substantial โgrey marketโ as far as this topic is concerned. By that, I mean most people I know who are eligible for a non-O visa (ie, age > 50 years) simply hire a competent visa agent who will 1) arrange the opening of a bank account (typically Bangkok Bank) and 2) shepherd your non-O application through Immigration without the necessity of transferring any overseas funds into this account (other than a small opening deposit and any additional funds youโd like to have deposited locally). Such visa agent services come at a reasonable cost but this will spare you from having to deposit เธฟ800k to sit in a bank here, and the hassle of dealing directly with Immigration and any other requirements such as insurance.
