以下是回复原文:Please note that when applying for a visa, even if taking into account what the applicants are requesting, the lodging of a visa application and the production of the required documents do not automatically lead to the desired visa.
I cannot comment on the actual reason(s) your visa was issued for a limited validity and the decision cannot be overturned but as general guidelines, the reasons for issuing short validity visas are usually:
near expiry dates of passports/ BRPs;
unreliable bookings;
misuse of previous visa(s).
Should you wish to travel back to France beyond the validity of your current visa, you will therefore need to submit a new application.
