In our country, the issue of dual citizenship of companies has been neglected, therefore, in the literature of administrative law, there are only two definitions of Iranian and foreign companies. Under these conditions, Iranian companies with international activities are forced to choose another name and register the company in a third country. This research was conducted in an analytical-descriptive method and its purpose is to investigate the administrative challenges of the presence of the mentioned companies in the country's oil and gas projects. It was concluded that in important projects, due to the lack of ownership of equipment, there is no confidence in the ability of Iranian companies, and in the conditions of sanctions, any communication between the company's foreign branch and the main office in Iran is monitored under the title of cross-border relations and can be costly. Inside the country, the aforementioned communications are viewed from a security point of view, which can be subjected to accusations such as money laundering and sabotage by the aforementioned authorities. The administrative system has not even paid attention to the all-Iranian companies with international activities, and this causes their lack of motivation in the aforementioned costly activities. In the relevant laws, there is no limit for the recognition of dual citizenship of companies, and the administrative-executive authorities can recognize the internationality of the company while approving the complete bylaws regarding the implementation of principles 41 and 42 of the constitution.
