I suppose when you apply for US SS, you are asked whether you are receiving other state pensions (which would then invoke WEP). You have options when you take your pensions. Why not take your US SS before the UK pension? At that time you can answer that you are not receiving any other pensions. Wouldn't that set up your US pension with no WEP? Then take UK pension later. Or do you have to answer that question every year?
