I used my original 500k for both my dependants. So 500k for main application. Once approved the same 500k for 2 dependants submitted at the same time. I applied in Taipei

When applying for dependants, you don't need to send anything regarding your soft power. It's actually quite simple. A copy of your passport, bank statements with at least 500k thb in their name (if they don't have a bank account under their name then you can give your bank account with a sponsor letter stating you will cover all costs of living) and a copy of your approved dtv.
