Iran does not recognize dual citizenship as such. For the Iranian government, in practice, dual citizens are Iranian citizens only. However, article 977 of the Civil Code of Iran deals with multiple citizenship. As a consequence of Paragraphs 4 or 5 of Article 976, some Iranian minors may have multiple citizenship.
