Sorry Folks, I got the Fiancée Visa bit wrong. The VAF1 fiancee visa is for those who wish to marry in the UK but then leave....i.e. you cant stay in the UK on it. For a Fiancee Visa that you can stay in the UK for up to 6 months before marrying you need the VAF4...i.e. a Settlement Visa. So the cost of getting Married in the UK and then living there is £395 more than getting married in Thailand.
example
Get Married in Thailand then apply for VAF4 Settlement Visa @ £515, then 2 years after marriage apply for ILR @ £750. Total £1265 over 2 years.
or
Apply for a VAF4 settlement Visa @ £515, get married in the UK within 6 months, apply for FLR @ 395, then 2 years after getting the FLR apply for ILR @ £750. Total £1660 over 2.5 years.
Again sorry for the Duff info!
So Bob the Fiancee Visa is easier and cheaper if you don't intend to live in the UK, but more expensive and with more form filling if you do intend to live in the UK.
It all seems a big rip off...I imagine the UK Government must be making a fortune out of Visa applications. Oh forgot to say if the Visa application is rejected, there is no refund though you can appeal.
