The article comprises the overview of the essential legal, administrative and financial means that the EU has at its disposal in case of rapid influx of immigrants, as well as a selection of major obstacles to the use of these tools, based on observation of the activities of the EU and its member states taken up to deal with the aforementioned situation which took place in 2015. Using the abovementioned observation and an analysis of relevant documents, it is argued that the refugee crisis of 2015 has revealed the necessity of a profound institutionalisation of the European immigration policy as the most effective way to overcome difficulties in response to such situations. The analysis leads also to the conclusion that the EU is caught in a dilemma of either suspending the Dublin system in crisis situations or creating a new system of intensive support for border member states.
