Thanks, that's perfect. I was unsure about how pensions were treated and the amount of cash savings required. The links cover pensions and my social security and also show how much we'll need in savings to cover any income shortfall when the higher income requirements kick in. I'm relieved that having the cash savings in a US bank is ok, I was afraid that I might have to move to the UK and open UK accounts before applying for the visa. It all looks ok. But if I was looking at this when I was first married in the US as a starving post-doc it wouldn't have been possible to qualify for the visa via income or savings.
