The Mason Project on Immigration (MPI) is comprised of distinguished faculty members at George Mason University whose teaching and research centers on the immigrant experience in the United States. Members of the MPI are drawn from multiple disciplines, including anthropology, sociology, social work, linguistics, and the humanities. All are committed to furthering a reasoned, empirically informed discussion and debate about the role of immigrant groups within the contemporary United States. Members of the MPI are committed to working closely with governmental agencies, community-based organizations, NGOs and foundations, the better to place public policies and discussions on an empirically informed and humane basis.

Activities have included original research on Virginia's Latino community, sponsorship of intellectual events and speaking engagements, and introduction of new academic programs in the field of immigration studies.
