Can I apply for a soft power DTV visa in Thailand with my spouse and children?

When applying for a soft power DTV visa in Thailand, you can submit your dependents' applications (spouse and children) simultaneously with your own. Each applicant typically needs to meet the visa requirements individually, and it's common that all involved have to pay the visa fees separately. There may be exceptions, especially for children, where a sponsorship letter can sometimes suffice instead of showing individual funds.
