As per the official cite one can apply for naturalization in France after completing 2 years in a French superior institute
2 ans d'études accomplies avec succès pour obtenir un diplôme d'un établissement d'enseignement supérieur français
My question is that if the normal duration of a course is 1 yr and for some reasons it is extended to 2 years, what are the rules in such a case? In particular one may assume that 2 yrs degree would be defined by number of credit hours and if so would one have to take a few more credit hours to be eligible. Where can one find more information regarding this issue?
