>"U.S. citizenship is the most coveted citizenship in the world. To give it up, it has to be pretty serious,"<p>It's pretty serious to give up your birth citizenship no matter where you're from. But, as someone with American citizenship, this doesn't ring particularly true for me. There are a number of passports I would trade, today, right now, for the one I currently hold. Anyone claiming American citizenship is the most coveted in the world is saying a lot more about themselves than they are the US.
