The United States is known as a nation of immigrants. Over the years the composition of immigrants has significantly changed. From receiving immigrants from primarily Europe, the United States is now home to people from countries around the globe. One of the common challenges encountered by immigrant and refugee families and youth is to successfully resettle and integrate into the host country that is culturally different from their country of origin. Depending on the context of migration, families and youth oftentimes face additional challenges ranging from potential trauma prior to immigration, language, employment, education, healthcare accessibility, integration, discrimination, etc. This book focuses on different issues experienced by immigrant and refugee families and youth as well as programs implemented to serve these populations. These issues pertain to the individual at a personal level (attachment, trauma, bi-cultural self-efficacy, behavioral problems, and mental health), family (parenting, work-family conflict, problems such as domestic violence), community (risk factors such as racial discrimination and protective factors such as social capital) and policy (immigration policy and enforcement). Part I of the book focuses on immigrant and refugee families and Part II focuses on immigrant and refugee youth. By increasing our awareness of issues pertinent to immigrant and refugee families and youth, we can better provide culturally respectful and sensitive services and policy to this population at a time when they are navigating between their host culture and home culture in addition to dealing with challenges encountered in resettlement.The book is a significant new contribution to migration studies and social justice, and will be a great resource for academics, researchers, and advanced students of social work, public policy, law and sociology. The chapters in this book were originally published in the Journal of Ethic & Cultural Diversity in Social Work.
