Application for 90-day Non Imm O Visa for reason of dependant Thai child

[Red Phoenix]

Hi,

I know that the financial requirement for a 1-year EXTENSION of a Non Imm O Visa for reason of a dependant child, only requires you to provide proof of having +400K funds on a personal Thai bank-account at the moment of application.

But what are the financial requirements when applying for the 90-day Non Imm O Visa for reason of dependant Thai child? Is it - like for the 1-year extension - sufficient to show evidence of the funds at the date of application. 

Or do you need to provide proof of seasoning of those funds for 2 months prior to the application?

ALSO: Is there for the Visa application a requirement to provide evidence that the +400K originated from abroad?

Thanks in advance for response - and also a link to the Thai Immigration document covering such case would be appreciated.

For a non-o visa application done at immigration the 400k baht only needs to be in the bank on the day you apply.
