The Cypriot nationality laws established in 1967 have been amended and replaced by the Civil Registry Law of 2002. Its recognition stems from Annex D of the Treaty of Establishment of the Republic of Cyprus. Article 50 of the Constitution of Cyprus grants veto power to the President (and Vice-President) of the Republic of Cyprus for any laws relating to the acquisition of foreign citizenship by a Cyprus national, however such veto has never been exercised.
Citizenship in Cyprus is based on the principle of ius sanguinis, when a child is born to at least one Cypriot parent. Cypriot citizenship is also granted upon marriage to a Cypriot national based on certain conditions, or through naturalisation. As of 2014 Cyprus has been running the Cyprus Investment programme which allows applicants to become citizens of Cyprus within six months, upon fulfilling certain investment criteria.
Dual citizenship is recognised and there are no laws in Cyprus prohibiting being a citizen of other jurisdictions. This recognition stems from section 8 of Annex D of the Treaty of establishing the Republic of Cyprus.
