The articles included in this book deal with various aspects of international migration analyzed from different methodological perspectives. What unites this collection of articles is that they deal with peripheral borders, separating rich and poor regions of our globe. They analyze the challenges and problems faced by the European Union and its member states, including Spain and Poland – states with external sea and land borders of the EU. The position of a peripheral country causes a number of problems related to illegal immigration, experienced by Poland and Spain alike. The United States face a similar problem on the border with Mexico. Undoubtedly, as a result of migration pressure, both the European Union and the United States increasingly resemble a besieged fortress.
