Firstly, the French School of Seoul welcomes children of French nationality so as to provide a continuity of French public education for expatriated families.
According to the available places, the French school also opens its doors to children of the host country as well as the children of other nationalities who stand benefit from a French education..
French pupils (58 % in 2009) :  Native French students coming from the French educational system (public institutions, accredited private institutions and those that are part of the network of French schools abroad) are automatically allowed where the administrative and financial conditions are fulfilled and within the limits of the available places. The pupils from non-accredited private institutions may apply for admission subject to an entrance test.

If the student is from 5 to 10 years old and not French-speaking he or she may be admitted within the limits of the available places, into the French immersion class (an intensive French-language class comprised of a maximum of 15 students of varying ages).
