Schengen-konventionen opstiller, selv om den skulle fastlægge den frie bevægelighed for personer i EU, tværtimod forhindringer for denne frihed, under alle omstændigheder med hensyn til dem, som kommer uden for EU.
Whilst claiming to facilitate the freedom of movement of individuals within the European Union, the Schengen accords actually put up barriers along the path to achieving this freedom of movement, at least for those who are from countries outside the European Union.
