If your visa application is denied, here's what you can do.

Disputes regarding short stay visas refusal

If a student is declined the granting of an entry visa to France, consular or diplomatic authorities will have to issue acceptable reasons to this denial from November 1st 2016.

Disputes regarding long stay visas refusal

In case your visa demand has been rejected, you may enter an informal appeal with the consulate by asking to reconsider its decision.

You may also refer to the Commission of Appeal against Entry Visa Denial in France ("Commission de recours contre les décisions de refus de visa d'entrée en France", CRV). This process is mandatory before appealing to an administrative judge. It is mandatory to file your demand within two months following rejection, starting on the notification of refusal decision, whether written or not. You, any person able to prove his/her interest to refuse the decision or a duly authorised representative may refer to the Commission (for example, a sibling). The Commission may reject the appeal or ask the Minister in charge of immigration and the Minister for Foreign Affairs to grant the visa issuance.
