What documents do I need to prepare for my DTV visa application for remote work in Thailand?

I’m planning to reapply for the DTV visa after being rejected more than 6 months ago (the previous application was for a boxing course, submitted through an agent). This time I’m applying based on remote work, and I’m do everything by myself here in Vietnam.

Documents I currently have:

• Signed employment agreement (in English)

• Letter from my employer (in English) confirming that my job is fully remote and that all clients are from my home country

• 6 translated payslips (translated by myself in Word) – my monthly salary is around 1,500 USD

• Original payslips (local language)

• 6-month bank statement (downloaded from my bank’s website in English, with a stable positive balance of around 700,000 THB during the entire period)

• Employer’s business registration certificate

Before I submit the application, I want to make sure I’m fully prepared:

• Do I need any additional documents?

• Do any of these documents need to be notarized?

• Is there anything else that you recommend adding?

• Should I include a short personal background letter? If anyone has an example, it would be very helpful.

Thank you very much in advance!
