Nauruan CBI Program Overview for UK Citizens
The Nauru Economic and Climate Resilience Citizenship Program (Nauru Citizenship by Investment Program) for UK citizens grants unrestricted dual citizenship and a fairly strong second passport to UK citizens who donate to the state fund.
The primary requirement is a non-refundable contribution of $90,000 to the Nauru Treasury Fund, increasing by $2,000 per dependent over 16. An additional $15,000 contribution is required for siblings ($17,000 per sibling over 16).
The contribution of British citizens is used to support national development and sustainability, including climate resilience initiatives to ensure a safe and sustainable future for Nauruan citizens.
British applicants must submit their applications through an Authorized Agent licensed by the Nauru Program Office, the official Nauru Immigration Department, and overseer of the Nauru Citizenship by Investment Program.

Risks and Compliance for British Citizens
For British citizens considering Nauru Citizenship by Investment, the program requires considering several risks and compliance requirements. Given the increased scrutiny and regulatory pressure on CBI programs–something highlighted in the UK’s decision to remove Nauru’s visa free status–applicants should anticipate more rigorous screening.
Even after approval, several successful applicants have raised concerns about additional questioning at border controls when using their Nauru passports. From a financial perspective, Nauru passport holders could face challenges when opening bank accounts, as some institutions apply stricter compliance checks to new CBI citizens.
