The Nationality Document Return Service (NDRS) is for applicants applying online to naturalise as British citizens or for those under the age of 18 who wish to apply to register as a British citizen. The service allows applicants to take their original documentation to their local authority, where the documents are copied and once the applicant leaves, sent to the Home Office, allowing the applicants to keep their original documents whilst the application is being considered.
To attend an appointment the applicant needs to contact their local authority directly and well in advance of the date they wish to submit their documents. There are mandatory documents that must be provided in their original format. There are 24 Nationality Document Return Services in Greater London and the fees vary according to the location.
