Background and Objectives: One of the foundations of the health system are nurses. Migration is one of the factors of reducing and losing this valuable capital. Methods: In this systematic review study, PubMed, Scopus, Web of Science, SID, Magiran and Google Scholar databases were searched without time limit and based on the Prisma method, and in order to evaluate the quality of the articles, critical evaluation checklists of the Joanna Briggs Institute (JBI) were used. Results: First, 265 articles were extracted. After screening and removing duplicate articles, unrelated, without complete text, the qualitative evaluation stage was performed, and finally 17 articles were included in the study. No intervention was reported in the articles and no study prioritized the identified effective factors. The causes affecting migration were classified into two main categories: Causes related to the country of origin (push factors) and causes related to the destination country (pull factors). The factors in the countries of origin and destination were counted in three areas: individual factors, social factors and cultural factors. Income, job position, job security, continuing education facilities and educational technology, team relations and facilities in the work environment and family status were identified as the most important factors affecting migration. Conclusion: Nurses and especially young nurses from third world countries had a high desire to immigrate. Considering the multi-dimensional causes affecting the migration of nurses, in order to manage this phenomenon effectively, special attention and structural reforms in the social, cultural, political and economic dimensions are needed

The Kurds are a group of Arian tribes and races who immigrated to Iran Platu, along with other Arian groups, and settled down in certain areas in modern countries such as Iran, Iraq, Turkey, Syria, Azarbyjan, and Armenistan.Although their settlement was largely in the above-mentioned districts, some smaller groups, due to their manners of living and earning their livelihood based upon economy and Cattle raising, and sometimes because of the cultural, political, and social reasons, were scattered in various areas of Asia , including estern Iran, during various centuries.There is no exact information available of the cause and date of their scattering in eastern Iran before the Safavid period.There is only certain sources available to mention their living in Khorassan in the early Islamic centuries, while other sources refer to their presence during the Taimorids and the early years of the Safavid era.However, the real movement of Kurds and their immigration to Khorassan began during the Shah Abbas reign and continued till the Nadir Shah rule.In this article an attempt is made to study the causes and reasons of this, more or less, compulsory immigration and how it happened while identifying some of its consequences.
