Overseas countries and territories (OCT)
The twenty-one overseas countries and Territories (OCTs) depend constitutionally on four of the European Union (EU) Member States: Denmark, France, the Netherlands, and the United Kingdom. OCT nationals are European citizens.
However, these countries do not form part of EU territory. Accordingly, they are not directly subject to EU law, but they benefit from associate status conferred on them by the Treaty of Lisbon. The aim of this association is principally to contribute to their economic and social development.
