To make sure the first salary will be paid on time, some elements need to be sent to Véronique Caules (either by email, or through Labandco)
You should try to send these as early as possible, so the salary will be sent on time.
You have to go to Délégation CNRS Paris-Centre, 26 rue des Fossés Saint-Jacques 75005 Paris.
For the residence permit, it will be necessary to bring: the passport with the visa obtained; the proof of the address; 3 photos.
