I currently have a retirement visa expiring in July. Due to the devaluation of sterling theres no way i can muster up £20,000 to bank the required 800,000, but in Oct we have an insurance policy maturing here in Thailand so i could get the 400,000 and change to the marriage visa. I meet all the criteria, Thai wife, 2 kids, dog etc. My thoughts are to hop to Phnom Penh in July and get a single entry non imm O but if i need the 400,000 banked for 2 months prior to the marriage visa application i will have problems, any advice please.
