Do I need a separate work authorisation to do research in France on this permit?

Unlike standard salaried routes, the Talent researcher permit comes with the right to work built in. The hosting institution does not need to obtain a separate work authorisation for you to carry out the research described in your hosting agreement.

This is one of the practical advantages of the Talent framework, removing an administrative step and making it easier for research bodies to bring in international talent. Your activity should remain consistent with the research project set out in your convention d'accueil.
