Without the protection of their adult family members or relatives, unaccompanied minors are considered to be the most vulnerable group of migrants who run the risk of exploitation and abuse during their flight (Hopkins & Hill, 2008; Thommessen, Corcoran & Todd, 2015; Keles et al., 2018). Reaching their destination does not mean however that they are then less vulnerable. To start with, at arrival they may be detained by immigration authorities due to their unknown migration status which endangers the best interest of the child - there are over 100 countries which detain children for migration-related reasons (UNICEF, 2017). Once they are let in the country, they can still be under risk of exploitation due to exhaustion or lack of resources, as may have to work off debts to their smugglers (UNHCR, 2018). At the same time, they are faced with specific challenges of integration on economic, social, and cultural dimensions and in many cases also face burdens of the reunification of their family. Growing anti-immigration tendencies in public opinion do not help either.In spite of their high vulnerabilities, there is relatively little attention for unaccompanied minors in the literature on 'forced' migration. This was an important reason to initiate this book. It covers different phases of the migration and integration processes of unaccompanied minors: from the decision to migrate and the migration journey, including the risk of exploitation en route, the period shortly after the arrival in the destination country, and the integration process. The migration process is to be considered as travel through time and space at the face of evolving and shifting insecurities reflecting various conflicts and conflicts of interest at the origin, transit and destination countries. Via this broad scope, this book aims to contribute to the literature on child migration, and specifically on unaccompanied minors and separated children.INTRODUCTIONIşık Kulu-Glasgow, Monika Smit, Ibrahim SirkeciCHAPTER 1Syrian Unaccompanied Minors Journeys to Germany and initial experiences upon arrival Raphael Kamp and Katie KuschminderCHAPTER 2'I just wanted to be safe': Agency and decision-making among unaccompanied minor asylum seekers Işık Kulu-Glasgow, Sanne Noyon, Monika SmitCHAPTER 3Ways into and out of exploitation Unaccompanied minors and human traffickingHilde Lid n and Cathrine Holst SalvesenCHAPTER 4Best Interests of the Child assessments to facilitate decision-making in asylum proceduresCarla van Os and Elianne ZijlstraCHAPTER 5Navigating the Immigration Process Alone: Unaccompanied Minors Experiences in the United StatesJennica Larrison and Mariglynn EdlinsCHAPTER 6Dropping out of Education: Refugee Youth Who Arrived as Unaccompanied Minors and Separated Children Aycan elikaksoy and Eskil Wadensj CHAPTER 7Eritrean Unaccompanied Refugee Minors in The Netherlands: Wellbeing and Health Anna de Haan, Yodit Jacob, Trudy Mooren and Winta Ghebreab
