Do I need to show proof of funds in a Thai bank account to extend my son's non-ed visa?

The inquiry revolves around extending a child's 3-month non-education visa to a 1-year duration. It has been clarified that typically, no proof of funds is required for an education extension visa. The financial proof is generally necessary only when a parent applies for a guardian visa in association with their child's education visa. Therefore, for the child's extension, documentation from the school is usually sufficient without needing to show bank funds.
