I’m an American currently working in Paris on a titre de sejour temporaire (salarier) that is due to expire at the end of October. This fall I’m going to leave my job to become a master’s student at the EHESS. Would be it possible for me to get a student’s titre de sejour without leaving France? My classes don’t start until November so it is unlikely that I will be able to formally enroll before early September - will this leave me enough time to renew my permit? Any help appreciated!
