Does My 5-Year-Old Daughter Need an Education Visa in Thailand?

There seems to be conflicting information regarding whether a child under 15 years old needs a visa for studying at an international school in Thailand. One source states that children of this age do not require a visa or extension, while another emphasizes the necessity of applying for an education visa within 21 days. It's suggested that children under 15 cannot be fined for overstaying, which complicates the situation further.
