That information is from google, when searched for "George Soros residence".
I made the assumption that nationality and citizenship were interchangeable. Apparently the distinction is blurred.
A British national is entitled to UK citizenship, which is a legal status. (I am aware of the British National Overseas but that is not the case in this instance) Nationality is, apparently, not a legal status, more of a birthright. Perhaps citizenship can be relinquished or removed, nationality cannot. Whether they (British nationals) actually take up the option of citizenship is for them to choose. I assume it is simply a matter of applying for a passport, although some countries do not allow dual/multiple citizenship/passports. This is not the case with UK. UK does allow multiple citizenship.
As I said before, I cannot understand how someone can have more than one nationality, if it is your place of birth. So the distinction is obscure.
or you couldve saved yourself the bother of writing all that diatribe and just said you were wrong
