Acknowledgements Throughout the almost nine years I have spent working on this book, many wonderful people have given generous support, guidance and insight. This acknowledgements section is my inadequate token of thanks to them. The kernel for this project arose from my doctoral work at, and with funding from, Queen Mary University of London (QMUL) School of Law from 2008 to 2012, where the inclusive and dynamic academic community and the fantastic supervision of Richard Ashcroft made it a great place to begin the research. I am also grateful for the encouragement of Jonathan Glover and the additional support particularly from Prakash Shah and Kate Malleson, and the QMUL PhD community, the Centre for the Study of Migration at QMUL and the LSE migration studies graduate reading group. Working at the UNU Institute on Globalization, Culture and Mobility in Spain from 2012 to 2015 provided exciting opportunities for engagement in political processes and colleagues with whom to discuss the questions presented here: Megha Amrith, Valeria Bello, Tatiana Diniz, Anna Franzil, Parvati Nair, Janina Pescinski, Regina Salanova and Francesco Vacchiano. As a Postdoctoral Associate and Lecturer at the Global Justice Program at Yale University in the US in 2015 and 2016, I met interesting and challenging scholars and enjoyed writing and thinking time. I am particularly grateful to Shmulik Nili, Thomas Pogge, Daniel Putnam, Alex Sayegh, and to Seyla Benhabib who also gave generous encouragement. I also thank students who attended my seminar class for providing an opportunity to put the book to a critical and fresh audience. The mutual support of fellow book-finishers Jess Melvin and Daniele Botti has been invaluable and their comments have been transformative. In 2016, during the final throes of this project, I took up a lecturer position at The Open University, UK. The welcome and support of my new colleagues have made it possible for me to finish the writing process. Collaboration with Katherine Tonkiss has been important to the formation of my ideas over the years. Feedback on the work presented in this book was also provided by participants at workshops and panels that she and I have organised, in particular the ‘Non-Citizen’ship’ workshop at the University of Manchester in 2013, and panels at the ECPR general conferences in 2014 and 2015 at the Universities of Montreal and Glasgow respectively. I also gained much from
