Anonymous participant if you are applying under soft power category you will be rejected. If you are applying under workation, and have documentation showing this has been your sole source of income for more than just a few months, and you have other significant investments, and remote work history, then there is a good chance it will be approved.
SilverRambutan9965 without a documented income from the work you will not qualify. You both also need the equivalent of the bt500,000 in each of your personal bank accounts. You are not married, so none of your documents can have any relevance for both of you. You work for the company owner, and all your documentation must show that, and that you get paid for your work, and have filed your own personal income tax reflecting that income from the work. As you are not married you are treated as two separate individuals. You can not use any of the same documentation.
Being that you are not married, you are treated as two completely separate people, having no relationship at all. You both need your own bank account with bt500,000+ in them. It doesn't matter what explanation you write. You are not married so treated as complete strangers, with each of you required to meet the financial requirements separately, with no exceptions. You should get the DTV for yourself, and while your partner's financials season in a separate bank account, enters on a 60 day visa exempt entry, so you both stay together. With the 30 day extension that can be taken, this puts you at three months of bank account seasoning. There are thai embassies that accept 3 months of bank account seasoning, and basically every embassy except those in Vietnam accept three months of the bt500,000 being in the account. Manila in the Philippines, from the last reports, accept just 30 days of the money being in the account. Taiwan also.
understand that on a frozen account, you have to update all your data anyway in order to get the money out of the account if they close it. Also, Bangkok Bank has been in the process of freezing all accounts held by foreigners over the last eight months, in batches. I had to update by data, when all my Bangkok Bank accounts were frozen last March.
Anonymous participant get your DTV based on medical procedures, then after you get it get the DTV for your other family members under the dependant category. That is the best way in your case. Once they are on the DTV as dependants/spouse they can get medical treatment. They do not need their own DTV based on medical treatment.
