Immigrants significantly contribute to the ever-expanding diversity of the populations of the countries they reside in, and they bring a wide array of cultural values, norms, and practices that help to make each country unique. The immigrant experience is multidimensional, consisting of at least one and sometimes multiple geographical relocations, and the various socio-economic, cultural, and psychological challenges that are encountered en route. In this volume, the authors provide insights regarding the multidimensional immigrant experience in different countries around the world. The heterogeneity of immigrant populations in various countries is highlighted in several chapters, and the importance of perceptions on our treatment of immigrants and how it affects the immigrants' experience is underscored. Several contributions examine the psychological stressors immigrants face, how these stressors affect their mental health status, and how to ameliorate these problems. A number of chapters discuss educational and socio-economic policies that affect immigrants and how to improve upon them. The common theme amongst the contributions in this volume centre on how to improve upon the immigrants' social, cultural, and psychological experience and to provide them with the tools they need to become healthy, integrated, and involved members of their new host country. This volume is an important step to help inform professionals and laymen alike on how we can support our immigrant populations and help them to break down the barriers they encounter in their migration.
