From 1966 - 1976 I worked and lived in U.K. where I was born as U.K. citizen. I paid into social security in England. In 1979 I came to USA and worked here almost 40 years and am now a US citizen. Since 1979 I have paid into social security here. Can WEP be applied to my UK pension which I only paid into while I lived in UK and wasn't a US citizen ?
