There will be no requirement for applicants to apply for or hold a valid BN(O) passport and successful applicants will be able to travel on a valid Hong Kong Special Administrative Region Passport. However, valid or expired BN(O) passports should be kept and submitted with an application as evidence of BN(O) status. Where a BN(O) passport has been lost, eligibility checks can be made using historical records held by Her Majesty’s Passport Office.
