April 29, 2017 will mark Donald Trump's 100th day in office. As a candidate, Mr. Trump laid out an ambitious plan on immigration for his first 100 days and provided greater detail in his immigration blueprint than on many other priorities for his administration. His promises included building a border wall paid for by Mexico, curtailing federal funding for sanctuary cities, deporting more criminal aliens, ending the Deferred Action for Childhood Arrivals program, "extreme vetting" for refugee admissions, and suspending immigration from terror-prone regions. This Migration Policy Institute discussion, with MPI's Doris Meissner and Muzaffar Chishti, former ICE Director Julie Myers Wood, and former DHS Assistant Seceretary for Policy and Planning C. Stewart Verdery, examines the administration's track record on immigration in its first months, the policies articulated in its executive orders, legal challenges, reactions by publics and policymakers, and what the long-term effects of these policies might mean.
