If you have 4 citizenships?

Question

from 4 different countries,

what exactly are you?

Answer 1

You're a primary citizen of the country you were born in.

Answer 2

What you are is subject to the laws of 4 nations.  When one of your kids visits one of them and finds himself pressed into mandatory military service because they consider him a citizen too you'll see what a silly idea it was.

Answer 3

a citizen of the world, perhaps?

Keanu Reeves has 4 citizenships if he chose to acknowledge them.

He is Lebanese because he was born in Beirut, Lebanon

he is English because his mother is English

he is Canadian because that is where he grew up and went to school

and he is American because his father is American.

the only two he uses are Canadian and American.
