 These states include most of the EU countries, as well as the EEC countries Norway, Switzerland and Iceland.Any person who is physically inside any of the Schengen states will usually be able to travel to any other Schengen state without hindrance from the law enforcement, even if he or she has no legal right to enter another Schengen Area member state.A person who wishes to immigrate illegally to a Schengen Area member state may therefore find it more practical to enter it through another member state.
