Each year, tens of thousands of aliens in the United States apply for asylum, which provides refuge to those who have been persecuted or fear persecution on protected grounds. Asylum officers in the Department of Homeland Securitys (DHS) U.S. Citizenship and Immigration Services (USCIS) and immigration judges in the Department of Justices (DOJ) Executive Office for Immigration Review (EOIR) adjudicate asylum applications. This book addresses what DHS and DOJ data indicate about trends in asylum claims; the extent to which DHS and DOJ have designed mechanisms to prevent and detect asylum fraud; and the extent to which DHS and DOJ designed and implemented processes to address any asylum fraud that has been identified.
