The United States Department of Homeland Security (“DHS”) published, on September 18, 2017, in the Federal Register, a notice that it would begin collecting certain information relating to immigrants’ use of social media as part of the National File Tracking System of Records. Since 1944, so-called Alien Files have been the official record system of immigrants, who have each received an Alien Registration Number. These files have historically contained basic information, such as each immigrant’s name, date of birth, date of entry into the United States, country of birth, parents’ names, and naturalization information, if applicable. The files also generally include any record of interactions between each immigrant and the United States government.
