France's post-study permit is the RECE (Recherche d'emploi ou création d'entreprise), which replaced the older APS in 2024. It gives you 12 months to look for graduate-level work or launch a business in France. You don't need an employer sponsor to apply.
The permit is available to graduates of a French Master's, MSc, Mastère Spécialisé, Licence professionnelle, or an equivalent programme. The 12-month version is non-renewable. There is an extended 24-month version available only to graduates from countries with specific professional-mobility agreements with France, including India, Benin, Burkina Faso, Cape Verde, Congo-Brazzaville, Gabon, Mauritius, and Tunisia. Nigeria is not currently on that list, so Nigerian Master's graduates get the standard 12 months.
During your RECE, you have full work rights and can take any job while looking for the right graduate-level role or building a business. Securing a qualifying skilled position on the RECE is the standard route into the Carte Talent, which is the main permanent residency pathway.
For general information on the RECE, refer to the official French government guidance at service-public.gouv.fr. We're not immigration lawyers and this page is educational, not legal advice.
