The movement of people across international borders is one of the most politically controversial issues in the world today. This class focuses on two different types of global migrants, immigrants and refugees, and explores why these two groups move out of their countries and how they are treated by receiving countries. Immigrants and refugees have traditionally been thought of as politically, legally and ethically different from each other and this class explores these differences, but it also explores the many ways that they are similar. Finally, the class explores a third type of global migrant that politicians and policy makers frequently promote, guest workers, and considers to what extent guest worker policies can effectively address the challenges and opportunities posed by the two other migrant groups. This class encourages students from a wide range of backgrounds, experiences and perspectives to enroll because it benefits significantly from including such diversity.
