Which visa?

Hi, my Thai wife and i married in Dec 2006 in Bangkok and she has a 2 yr visa for living in England where we have been since Dec 12th 2006. My house is on the market in England and we plan to return to Udon to live in a small village about 15kms from Udorn (my wifes village).I am 59 yrs old she is 48 so my plan is to retire there. I currently have a small pension approximately 3500 baht per month but plan to invest the bulk of my money from the sale of my house in the UK to get a return around 400/450000 baht per year and still have the capital on deposit in England. I will also have a pot about 50k readily available (running costs etc) What visa should i apply for as i will not be able to show funds available(only capital assets) for a 3 month period unless we stay in England after i sell my home for 3 months even though i will be solvent.Also where is the best place to put my pot money, in a Thai bank or draw from my account in the UK using ATM,s in Udon as i did on my previous visits there( Nationwide a/c no charge for using abroad). Any advice or suggestions will help.

get a non immigrant type O visa before you come (based on marriage to a Thai)
Its about 100 pounds and will allow you to stay here about 1 year BUT only in 90 day increments when you will have leave/re-enter Thailand to activate the next 90 segment.
After 1 year when things have settled down - you will have a better picture of what you want to do - extend the 'marriage visa' or apply for a retirement visa.
Both of these routes will require proof of income though (40,000 per month for the marriage visa or 65,000 per month for the retirement visa OR (for the retirement visa only) a lump sum in the bank of 800,000 baht (and was there for the preceeding 3 months prior to application)
Keep as much of your money in the UK
You should be able to get 5 or 6 % interest - as oposed to 3/4 % or sometimes even nothing, here.

Thanks for the info, i could manage the "lump" in the bank ,is that in England or Thailand though.

Most definitely Thailand
And they will want to see your bank books to make sure that there is movement of this money and its not just sat there for visa purposes. Otherwise they will 'demand' to know what you are living off.

Its easy to see why some people go home once a year and get a new non imm visa and don't worry about lump sums, extensions or 'somewhat difficult' immigration officers (ahemmm)

Yes,thats what I'm doing.
I got a 12 month non-immigrant visa from the UK and after it expires will be looking to get a marriage visa.
You have to leave the country every 90 days with the non-immigrant visa but its an easy trip from Udon to Nong Khai.
I had the same type visa 3 years ago and I used to look on a trip to Nong Khai as a day out with the Mekong river,market and riverside cafes.
This time round I'll probably spend a bit of time in Laos as well.
I'll get my pension transferred monthly to a Thai bank account in the hope immigration looks on my application favourably !
