On November 9-10, 2017, CSI and the Cornell Population Center (CPC) brought together world-class social scientists, legal scholars, and local community organizers for a conference on the criminalization of immigration. At the conference, scholars exchanged ideas, discussed results of research, engaged with immigration law practitioners and advocates, and identified policy levers that might balance the rights of countries to enforce their borders with the need to protect the basic civil and human rights of immigrants.
