Scholarly debate, legal rules and policy on dual nationality suffer from a fatal flaw: the various situations of dual nationality are conflated in one single category, linked to a single policy. This article argues that the debate would win in clarity if the various situations were untangled. In order to demonstrate the need for more discrimination in situations of multiple citizenship, two cases are discussed: the first one relates to the various situations which may come under the heading of dual nationality. In particular, the argument is made that dual nationality arising out of birthright citizenship should not be confused with situations where a second nationality is voluntarily acquired. The second case where more segregation is in order relates to the treatment of the two nationalities possessed by an individual. The argument goes that the two nationalities should not be treated on equal par, as they rarely have the same value and weight.

下一个前沿：双重国籍作为一个多层次的概念

关于双重国籍的学术争论、法律规则和政策存在一个致命缺陷：双重国籍的各种情况被归为一类，与单一政策相关联。这篇文章认为，如果理清各种情况，辩论就会清楚地获胜。为了证明在多重国籍的情况下需要更多的歧视，讨论了两种情况：第一种情况涉及可能属于双重国籍的各种情况。特别是，有人认为，出生公民权产生的双重国籍不应与自愿获得第二国籍的情况相混淆。第二种需要更多隔离的情况与个人拥有的两个国籍的待遇有关。
