Dual Citizenship vs. Dual Allegiance
Dual citizenship arises when as a result of the concurrent application of the different laws of two or more states, a person is simultaneously considered a national by the said states.
Dual allegiance, on the other hand, refers to the situation in which a person simultaneously owes, by some positive act, loyalty to two or more states.
While dual citizenship is involuntary, dual allegiance is the result of an individual’s volition.
