The new Eastern border of Schengen area and the irregular immigration into and from Poland (ARI)
Poland has been forced to design a stricter migratory regime firstly for EU accession and secondly, for entering Schengen espace. Since December 2007 Polish eastern frontier (stretching across 1,200 kilometres from the Baltic to the Carpathians) has become one of the few points in Europe at which it is possible to control human spatial mobility on the east-west axis.
