At the present time, the presence of innumerable foreigners in Iran and many Iranians in abroad and the marriage of the Iranian citizens with the foreigners, the respect of the principle of uniform nationality of the couples in the civil law are confronted with certain obstacles that authorise application of principle of plurality of nationality. On one part, Iranian legislator for avoiding the dual nationality and statelessness of Iranian women are accepted that if the law of husband imposes its nationality to wife at the time of marriage, this woman loses her Iranian nationality. In this situation, the change of nationality of the Iranian women seems contrary to principle 41 of the constitution. Because, the freedom of change of nationality of the women is limited in this case. On the other part, of the foreign women in the case of marriage with the Iranian men become Iranian. In this case also effective giving of Iranian nationality and the diplomatic protection of Iranian state for the people who their attachment towards Iran is not known and their condition of capacity is not studied is in some illogical and contrary of principle 42 of the constitution. In this article, we study reasons of attention of Iranian legislator to the principle of uniform nationality in family, the methods of application of this principle by differing aspects, the practicable difficulties in application of this principle for the Iranian citizens and Iranian state and finally certain propositions like the plurality of nationality are presented.
