> renounce citizenship.

Isn't the US one of the few (the only?) countries which makes this really hard?

Like, if I wanted to get rid of my citizenship (European country) all I need to do is get another one, it is void the second that happens. And even if it wasn't, I do have the right to get rid of the citizenship at any time, no reason or justification needed.

If I remember in the US it is not only expensive but also they for some reason have this system where they can deny you renouncing your citizenship.
