The Code of Entry and Residence of Foreigners and Right of Asylum (code de l'entrée et du séjour des étrangers et du droit d'asile - CESEDA) establishes that for the purposes of applying for this type of visa, financial resources must not be lower than the current French minimum wage (€1,766.92 per month net as at 1 January 2024).
However, it should be noted that even if you prove you have sufficient financial resources, the French consulate or prefecture in France has no obligation to issue the corresponding visa or residence permit – they have the right to issue a visa or permit, or to refuse issuance. The final decision will depend on the general impression made by your dossier and your reasons for moving to France.
