Iran has yet to be the subject of research looking into the gaps in the nationality law, which, could create and perpetuate statelessness. There were however, several pre-identified populations, some members of which are believed to be affected by statelessness, as well as gender discrimination in the nationality law - which causes and increases the risk of rendering children stateless. Therefore, based on this previous knowledge of potentially stateless populations, and the gaps/lack of certain safeguards against statelessness in the nationality law, this research provides a foundation for understanding nationality and statelessness in the country.
