If you are a citizen of the European Union, the European Economic Area or the Swiss Confederation, you do not need a visa. Otherwise, you must have a type D visa stamped « Student ».
To obtain a visa, go to the French Consulate or French Embassy in your home country to find out which documents you must produce and how long it takes to obtain them or go to campusfrance.org.
