For a paper British citizenship application, the process is indeed simpler than the online route. You provide the physical application form (which includes integrated referee declaration sections) along with your passport-sized photograph to each referee [1][2]. The referees fill in their personal details and sign their respective sections directly on the paper form you have given them—they do not need to print anything themselves [1][2]. One referee must also sign the back of the photograph to confirm it is a true likeness of you [1]. Once both referees have completed and signed their sections, you collect the completed form and photograph and submit everything by mail to the Home Office. This manual, paper-based approach avoids the hybrid digital-then-physical workflow of online applications, making it more straightforward for referees since they are simply writing on the official form you have already provided.
