The different types of “Student” visas
What nationality, what visa to come to France?
Foreign students with a foreign secondary school leaving certificate who wish to enrol in pre-graduate studies at a French university must apply for preliminary admission (DAP). This is done at the cooperation and cultural action branches of French embassies abroad or agencies of CampusFrance, when they exist. This formality concerns only those students who wish to enrol in the first year of university. Students who wish to enrol in a higher level of studies must contact the university concerned directly. Those who wish to enrol in a Grande Ecole, a private institution, a University Technological Institute (IUT), or a department for advanced technicians (STS) must contact the selected institution directly.
