Any personal data collected upon registration or lodging of an application for international protection and during the personal interview should be considered to be part of the applicant’s file and it should be kept for a sufficient number of years since third-country nationals or stateless persons who request international protection in one Member State may try to request international protection in another Member State or may submit further subsequent applications in the same or another Member State for years to come. Given that most third-country nationals or stateless persons who have stayed in the Union for several years will have obtained a settled status or even citizenship of a Member State after a period of ten years from when they are granted international protection, that period should be considered a necessary period for the storage of personal details, including fingerprints and facial images.
