Do I need to keep my funds in a current account for three months to apply for a DTV visa in Thailand?

saving account is also ok

I applied from Taipei December last year. Was in similar situation as you described. I moved it to my current account create a statement the day before application. No problem

The 500k does not need to be seasoned for 3 months. It depends on the embassy you apply from. If applying from London a final balance of 500k with several months statements is ok. You can see posts of people transferring money same day or day before and approved. Instant access to funds required

The financial requirement of 500k must be liquid and available when you submmit the application. Some people say you need to have it for 3 months when i applied for mine last week in Hanoi i sent 6 bank statements. The DTV visa is quite broad in how you can apply for it. If your finances are not up to what they require have an sponsor and go with one of the soft options. If you go with the ( your own business route) they need a structure and looking into what you are providing it might complicate the story. Stay simple and you would get the visa . Good luck 🙏

Need to be in bank account with instant access
