French application of work welfare (Revenu de solidarité active)

The French government decided to change the work welfare application procedure applying the once-only principle (Program name: Dites-le-nous uns fois). In the future, citizens can apply for the procedure online and the administrations have to exchange the documents they already have. Citizens will just have to provide information that the public administration does not have yet. The application of the once-only principle will simplify the life to citizens and facilitate the application.
Before, citizens who wished to apply for social welfare (Revenu de solidarité active) in France had to complete an application form and file it to the service department or to another organisation that will process their application, such as the Caisse Family Allowances (CAF) or the Social Mutualité agricole (MSA). Depending on their situation, citizens often have to attach a lot of documents and information, f.e. their income and family situation - even if these information are already somewhere in the public administration. This procedure is very complex and takes a lot of time. Due to these circumstances, there was a number of citizens who were discouraged and did not apply for RSA.
