Migrations are an integral part of human life. They depend on various factors such as different climatic conditions, war conflicts, religious and political persecution, economic considerations, etc. The single most important role in this is the creation of a better and safer life. Escaping conflict, persecution, etc., seeks to improve an individual's safety and quality of life. The recent migrant crisis shows how several million people are fleeing various conflicts and negative impacts. The entire crisis has been triggered by an Islamic radical organization known as ISIS which, through its brutal killings, rapes, persecutions, etc., drives non-refugees into refuge. Although the so-called. The Islamic State has been defeated and there is no longer a war of conflicts to the extent that the vast majority of refugees do not return to their countries but seek to reach developed Western European countries legally or illegally. Due to the lack of labour force in Germany and the conditions it offers, it is one of the fundamental goals for migrants. However, there are many problems along the way, especially those related to the security of not only the local population but also the migrants themselves. The local population's resentment among migrants is increasing, especially in areas where there are refugee centres, or where there are more migrants. There are also criminal acts committed by migrants, which increases the sense of insecurity of the local population. Croatia does not currently have any significant problems in this regard, but such problems may arise in the near future, especially due to the fact that the migrant route now running across BiH has changed. One of the migrant destinations may also be Sinj, which would then find itself in security and economic problems. The aim of this paper is to highlight the security problems that may occur with the significant arrival of migrants in the Sinj area, and what implications they may have for life in the wider area of this city. The analysis shows that currently, regardless of certain illegal transitions, the local population feels safe, but it is important to conduct situation analyses and communicate with neighbouring countries regarding the situation with migrants so that they can promptly respond to potential problems.
