Applying for French citizenship is a delicate and demanding process in which every detail matters. It is a complex procedure on which your future depends. A mistake, a missing document, a poorly prepared interview — and you lose not only time but also your chance. The filing rules have recently become stricter: under new directives from the Minister of the Interior, prefectures may refuse to accept a file at the very first stage if it does not fully meet the requirements. This means a file may not even be examined if it contains an error, lacks a document or has something not completed in the required form. The result is lost time and a chance of citizenship postponed by a year or more.
