Background and Objectives: However, unauthorized frontiersmen will be deprived of the rights and freedoms normally envisaged for licensed foreigners. But from the point of view of international law, governments are bound to enjoy these kinds of aliens with the rights and freedoms most of which are of human rights origin. The purpose of this article is to examine the rights and freedoms of unauthorized frontiersmen from the perspective of international human rights law and the Iranian legal system. Methodology: In the writing of this article, it is first evaluated by deductive study of library and documentary sources of international law, rights and freedoms of aliens. Then, with an analytical approach and an inductive approach, each of these rights is discussed. In the case of the Islamic Republic of Iran, the domestic legal sources and the practices of the national institutions concerned with the inductive method with a descriptive-analytical approach are studied through library and documentary studies. Findings and Results: The results show that although unauthorized boundaries do not meet the legal requirements for entry into the country, they have rights and freedoms such as, the right to life, the right to citizenship, the right to freedom of expression and opinion. Or the right to return to their home country, which is required by international law. The Iranian legal system has also committed itself to a number of international commitments, as well as religious teachings and the foundations of Islam, to the human rights and freedoms of unauthorized transgender people, which are embodied in the constitution and subject matter laws.
