The U.S. laws explicitly neither prohibits nor allow for dual citizenship. What that means is that, it usually turns on the citizenship/nationality laws of the other country, whether you can be dual citizen. So in your case, if the country that you have retired to and live in, if that country allows you to become a citizen and retain another citizenship, then you can be a dual citizen of that country and the U.S. You can read a bit more about dual citizenship here . By becoming the citizen of that country, you will not relinquish your U.S. citizenship. There are certain ways in which a U.S. citizen can lose his/her citizenship, but it's usually not because of acquiring another citizenship.
