Let's hope he never commits a criminal offence .... and gets deported!
Even if you're a citizen that naturalized, can't they withdraw your citizenship and deport you? Didn't they do that to that extremist Muslim cleric? The one they sent to Lebanon?
Well, my friend's husband is American, like myself, so he can hold dual nationality, I think he just doesn't like the idea of swearing allegiance to the Monarchy at the ceremony. He said he'll feel less American if he does take up British citizenship.
I know the Queen doesn't have any real power. And that you all just keep the Monarchy around for traditional and tourism purposes.
Personally, I'll jump at the chance of British citizenship. If you have American citizenship, and British (E.U.) citizenship. The world is your oyster I think. Unfortunately, I have to wait awhile because I'm here on EEA rules.
