What are the requirements for the Digital Nomad Visa (DTV) in Thailand regarding financial proof and dependent applications?

Hi all,

My wife and I are planning to base ourselves in Thailand for the next 2–3 years and (fingers crossed) start our family there. I’m a remote employee for a U.S. company and my wife freelances. A few questions on the DTV process:

1) For the 500,000 THB financial requirement, will bank statements from investment/brokerage accounts be accepted, or do they need to be from a cash/checking/savings account? We have sufficient funds, but one account dipped below 500k recently due to an investment.

2) I’ve seen people mention an employer letter confirming permission to work remotely from Thailand. Is this actually required, and what wording do they expect?

3) I’ve also read that some consulates ask for recent payslips. My wife’s income varies as a freelancer. Because of Trump's shenanigans, lots of business (her clients) put a pause the last six months so he income has been very low to 0. Things are finally kicking in back into gear and she is signing up a few clients, but they won't likely start right before we apply for the DTV visa. Would this be a problem for her application even though we cover the minimum $ requirement? Would you recommend to have her as a dependent, rather than apply for her separate visa?

4) If we apply for her as a dependent, does that mean I have to first get my DTV visa approved and then apply for her as a dependent? Is there a way to do it simulatenously?
