Immigrants and their descendants typically identify with ethnic, national, religious, and/or regional groups, in various combinations and with varying degrees of compatibility or conflict. Research and theorizing on these patterns of identification, as represented in this issue, suggest guideposts for future research and domains for policy development. Here, we identify some of the issues that warrant additional research and we consider implications of existing research on dual (or multiple) identification for the development and implementation of policies related to immigrants. Examples of the former include the need for careful specification of concepts, the consideration of multiple dimensions of identity, deeper examination of identity meanings, methodological extensions in time and space, and greater theoretical integration. Policy development will require greater attention to various identity combinations, advocacy for national inclusivity, the promotion of sites for positive intergroup contact, and maximizing the potential for immigrants with multiple identities to help bridge intergroup gaps.

为什么移民的多重身份很重要：对研究、政策和实践的影响

移民及其后代通常以不同的组合和不同程度的兼容性或冲突认同种族、民族、宗教和/或地区群体。如本期所述，对这些识别模式的研究和理论化为未来的研究和政策制定领域提供了指导。在这里，我们确定了一些需要进一步研究的问题，并考虑了现有的双重（或多重）认同研究对移民相关政策的制定和实施的影响。前者的例子包括需要仔细规范概念、考虑身份的多个维度、更深入地检查身份含义、时间和空间的方法论扩展以及更大的理论整合。
