GREECE SIGNS SCHENGEN AGREEMENT
Greece signed the Schengen Agreement on 6 November 1992 and thus became the ninth member of the Agreement. The treaty was initially supposed to come into effect on 1 January 92, but not all of the Member States have ratified it and political, organizational and technical problems have delayed the introduction of security and border control measures common to all Schengen States as stipulated in the agreement.
