You will need to contact the French consulate in your country. The time required to obtain an appointment for a Schengen visa should not exceed 15 days (unless special circumstances apply, i.e. if it is the ""high season"" for example) and the time taken to issue one should not exceed 15 calendar days.

The person applying for the visa must provide the consular authorities with all necessary items of proof concerning the purpose of the envisaged stay and the related conditions (sufficient resources, accommodation which can be demonstrated by means of an accommodation certificate) and must ""supply all information making it possible to assess the applicant's willingness to leave the territory of the member states"".
