All of the following are true of 'dual citizenship' laws EXCEPT:

NCERT (2026-27): “Communities, Nations and Nation-States …
Generally speaking, in recent times there has been a one-to-one bond between nation and state (one nation, one state; one state, one nation). But this is a new development. It was not true in the past that a single state could represent only one nation, or that every nation must have its own state. For example, when it was in existence, the Soviet Union explicitly recognised that the peoples it governed were of different ‘nations’ and more than one hundred such internal nationalities were recognised. Similarly, people constituting a nation may actually be citizens or residents of different states. For example, there are more Jamaicans living outside Jamaica than in Jamaica – that is, the population of ‘non-resident’ Jamaicans exceeds that of ‘resident’ Jamaicans. A different example is provided by ‘dual citizenship’ laws. These laws allow citizens of a particular state to also – simultaneously – be citizens of another state. Thus, to cite one instance, Jewish Americans may be citizens of Israel as well as the USA; they can even serve in the armed forces of one country without losing their citizenship in the other country. …”
