Territoire britannique de l’océan Indien : à savoir avant de partir

L’essentiel

  • Not an ordinary tourist destination: new permit applications are paused except exceptional cases.
  • Outer-island yacht permission does not authorise Diego Garcia access.
  • No ordinary nationality-based tourist visa or visa-free rule is asserted in this guide.

Entrée et visas

Restricted territory: This is not an ordinary tourist destination. BIOT has paused consideration of new entry-permit applications since 31 March 2026 except exceptional cases. Diego Garcia access is restricted to authorised official or mission-essential travel. Check the linked immigration guidance for other nationalities and purposes.

Validité du passeport: UK advice: at least 6 months after arrival and 2 blank pages.
