The core feature of the Schengen Agreement is the abolition of internal passport checks between its 29 member states. Once an irregular migrant successfully breaches the EU's external perimeter (such as landing by boat in Italy or Greece), Schengen functions as a border-free corridor.

• The French side (Schengen): Wide open, allowing migrants to arrive freely in Calais.
