Do I need to show proof of 500,000 baht on each entry for a DTV after my initial application?

When applying for a DTV visa in Thailand, proof of having 500,000 baht is generally required only at the time of application. There are indications that some individuals may be asked for this proof upon re-entry, particularly if applications are made from certain countries' embassies. However, it seems that most cases require this documentation solely during the initial application, not upon re-entry.
