Do I need three months of bank statements for my wife's DTV application as a dependent in HCMC?

The user is applying for a DTV visa for their wife as a dependent in HCMC and questions whether three months of bank statements are necessary to show the required balance, or if it's acceptable to top up the account shortly before applying. Comments clarify that the wife will need to provide the same financial documentation unless she is sponsored, in which case a sponsorship letter and proof of seasoned funds are required. Additionally, it's noted that some embassies might require a combined proof of funds, totaling at least 1 million THB, to avoid complications.
