What are the options and costs for the DTV visa in Thailand, especially for married couples?

The DTV visa requires two separate applications if one spouse is working (or engaged in soft power activities) and the other is applying as the spouse of the primary applicant. Each application incurs a fee of approximately 10,000 baht, though actual costs may vary by embassy. Additionally, evidence of savings, specifically 500,000 baht each, is necessary for both applicants.
