Okay, thank you for the clarification. I knew this information previously, I was just hoping you knew of something I didn't. My ancestors came from Switzerland many years ago and using this sort of method wouldn't work for me. I have heard that in Switzerland it is relatively difficult to get citizenship, as I've been a few times and asked around while visiting.

I do know for certain (my wife is Swedish and American) that you are allowed at least dual citizenship as long as you don't present yourself at the border with your passport issued by another country. There are several technicalities which "rescind" your American citizenship, but they mostly are not enforced unless you make a big deal out of it (e.g. turning in your passport to an overseas American embassy and declaring that you are no longer a citizen), but presenting at the border your passport issued by another country has lately been interpreted to mean that you are declaring yourself citizen of that nation. IANAL but many of these kinds of things are not black-and-white and depend largely upon the border agent which you are dealing with.

Again thanks for your reply!
