In the Van Hool Islands, yes. The Prime Minister, Ariella Aitken, is a dual Van Hool-South African citizen, while the Acting Prime Minister, Odelia Ryskamp, is a dual Van Hool-New Zealand citizen.

No.
You must be a born and bred Versilian, and hold exclusively Versilian citizenship.

All you need is to have Skyhookedian citizenship. So yes.

We've never gave two shits either way, although Ewan McGregor's announcement back in 1959 after his takeover from the Communist coupers that "in a time of war, we can't have people who either - potentially - could support us or could support our enemies in Assembly" is still held as an unofficial priniciple to this day. But then again, we've never gone to war, are not at war, and we still refuse to give two shits either way to this day...

There are no laws prohibiting someone who holds dual citizenship from serving in any political office.

Yes, dual citizens can hold political office

Dual citizenship is already illegal once you turn twenty one years old in Cascadia. All white-dual-citizenship persons that are also born residents are forced to renounce it and give a pledge to White Cascadia as a nation. Non-born residents of other races must either renounce it and give the pledge or be deported to the other nation, while non-born non-whites are deported at age 21. With the exception of out standing achievements. Born while non-white residents are given the same treatment as white non-borns.

So, in short, a firm no.

King Emillio Myles:

Interviewer: Whats so funny?

King Emillio Myles: Why the hell would we let any other race have a place in our government? We have a constitution saying 'no African shall ever be ruled by another race again' . Now does your question seem logical?

Interviewer: Well what if it was an "African American----

King Emillio Myles: Let me stop you right there....this interview is over. See yourself out.

According to the Constitution, to be a King of TurtleShroom, one must be a natural born TurtleShroomer. That means that the candidate is born, hatched, or germinated within the borders of TurtleShroom, or in territory subject to formal TurtleShroomian control.

The Constitution is silent on dual citizenship, but no creature can hold another office while serving in a government position. Also, all creatures serving in public office must be citizens of TurtleShroom.

We don't give a damn. Our emperor is from the Lowlands and Saxony. 29% of the Imperial Senate holds dual citizenship.

Ah yes, another thing that is illegal in the DGES. It is only natural that we would outlaw these privileges, or anything, really.

We must have mentally and physically strong politicians, so, of course.
