According to the ACLU, "millions of aspiring Americans apply to U.S. Citizenship and Immigration Services (USCIS) each year. But under a previously unknown national security program known as the “Controlled Application Review and Resolution Program” (CARRP), the government excludes many applicants from Arab, Middle Eastern, Muslim and South Asian communities from these opportunities by delaying and denying their applications without legal authority."
