After your study visa expires, you cannot legally stay in France without applying for a residence permit or visa extension. You may transition to a temporary residence permit (APS) for up to one year to seek employment, provided your degree meets French requirements. Alternatively, securing a job may allow you to switch to a work visa.
Overstaying your visa risks fines, deportation, or future entry bans. Check with the French Office for Immigration (OFII) or a legal advisor for updated rules. Early application for extensions or new permits is crucial to maintain legal status.
