Happy me!
I am a UK citizen.
I applied for the "Non O" visa 15 days ago and received approval this morning.
I supplied 4 months of PDF format bank statements in a single file showing ample funds.
A receipt showing a 6000 THB deposit on a serviced apartment in On Nut, BKK.
A one way ticket and a uk utility bill showing my name and address .
Thanks for all the advice given previously.
