Over the past decades, the forces of globalization have helped created a huge wave of immigration. The relationship between globalization and immigration has been intensely examined in the last decade with a focus not only on whether and how much globalization has caused international immigration but also how to promote and sustain a just global system for the growing number of immigrants. This study selects three developed countries with different welfare state philosophies and traditions-Australia, Sweden and the United States-and compares how they cope with the growing number of immigrants and their various needs. This paper reflects thinking about states' ability to redistribute resources, about the ability to agree upon a unified theory of welfare rights in a diverse society, and the feasibility of opening nations' welfare systems to all immigrants in the globalization context and from a rights-based social work perspective.
