Narenji v. Civiletti

In response to Iran's takeover of the U.S. embassy and the resulting hostage crisis, the Attorney General (defendant) issued a regulation requiring all nonimmigrant Iranian post-secondary students to report their residency and immigration status to an immigration officer, with deportation proceedings threatened for noncompliance; Narenji (plaintiff) sued, arguing the regulation's nationality-based classification violated the Equal Protection Clause, and the district court agreed, prompting the government's appeal.
