In order to stay in France, you need a French residence permit. It will be your identification card in France. From your arrival, go immediately to the Prefecture of your city to get a residence permit request form. You will also need the following documents:

-student card or registration certificate,

-evidence of accommodation,

-evidence of funds,

-civil status certificate issued during the past three months,

-some identity photographs,

-a stamped envelope,

-do not forget a copy of your passport.

If the card is not given to you immediately, the Prefecture will give you a receipt, which is a sort of residence permit that lasts three months. In some cities, you will be asked to attend a medical check up at the International Migration Office.
