The first transatlantic IMISCOE Summer School was a big success. In a stimulating Princeton environment a group of 30 PhD candidates from the US and Europe followed a five-day program with lectures by Maurice Crul, Marco Martiniello, Karen Pren and Douglas Massey. Additionally the group participated in a panel discussion at the City University New York (CUNY) with Richard Alba, Nancy Foner and Phil Kasinitz.
