How can I switch from a No O retirement visa to a parent visa in Thailand?

Hi Todd. You gave me great advice before and I thank you.

I have a new situation that needs a clear solution

Currently I am on a no O retirement visa. Due to a change in my finacial situation I will not be able to keep a bank balance of 800000 for the equired period of time.

However, I am a single dad of a 16 year old Thai son.

I want to change to a parent visa to reduce the financial requiement to 400000.

I have a UK state pension that equates to about 25000 per month and the transfers show in my Thai bank for at leas 2 years.

This equates to about 290000 per annum.

I also have a continuing current account balance which if combined with the pension is more than the 400000 requirement.

Is this ok?

What do I need to do?

My old addled brain needs some help as I get conflicting advice.

Many thanks.
