According to reports and statements from former Homeland Security officials, the DHS has initiated three "pilot programs" to analyze social media posts during the visa review process. Prior to 2014, a DHS policy prohibited social media monitoring by immigration officials. EPIC successfully obtained documents in 2012 detailing the DHS social media monitoring policies, including instructions to analysts to monitor criticism of the agency. EPIC also submitted a letter to congressional leaders, outlining how DHS officials misrepresented their policies in a Homeland Security Committee hearing. EPIC wrote that the DHS' monitoring program should be suspended, as it exceeds the agency's statutory authority and chills First Amendment activity.
