Advice for dual nationals and holders of British Overseas Territories (Cayman Islands) Passports applying for a UK Passport
Advice from the UK Passport Office makes clear that dual nationals and Cayman Islands passport holders who are applying for a UK passport should send in a full colour photocopy of their existing passports, instead of sending in the original document. This means that Cayman Islands passport holders will not be without a travel document when making their UK passport application.
