What are the financial requirements for the Soft Power DTV visa in Thailand for spouses and children applying together?

Hi everyone,

My husband and I are preparing to apply for the Soft Power DTV from the United States. He will be attending a Muay Thai program, and I will be attending a cooking school. We will also be bringing our 4 year old child.

We currently have over 2 million THB equivalent in savings. Does the financial requirement need to be in separate accounts for each applicant, or can the funds be held in a joint account?

If both spouses are applying for their own DTVs rather than one spouse being a dependent, can the same account balance be used to support both applications, or does each applicant need to show their own qualifying funds?

Since we will be applying from the United States, are there any U.S. specific requirements, challenges, or recommendations we should be aware of?

For those who have gone through the process with a spouse and child, are there any tips, lessons learned, or things you wish you had known before applying?

Thank you in advance for any advice.
