On August 28, 2018, Bilzerian flew to Armenia with his brother Adam and father Paul in order to take their oaths to obtain Armenian citizenship and join the Armenian Armed Forces.[40][41] On that same trip he visited the Republic of Artsakh where he visited a shooting range, and fired weapons there.[42] The government of Azerbaijan sent a note of protest to the United States over these actions due to the contested status of Artsakh, and summoned U.S. Chargé d'Affaires William Gill to take an official note of protest addressed to the U.S. Department of State. A court in Baku issued an arrest warrant for Bilzerian and put him on the international wanted list.[42]
