“Our agency is Campus France approved”
That is false, and Campus France states it plainly : no agency is approved. A paid intermediary makes neither the pre-registration nor the visa easier. Support can be valuable, but it grants no privileged access to the procedure.
“You have won a scholarship, please pay the file fee”
Fake scholarship offers circulate by messaging apps and social media, sometimes using the name of real institutions. No public scholarship is paid for in advance. Always check on the organisation’s official website, never through the link you were sent.
“Send the deposit, the flat will go fast”
Never pay before visiting, or having someone you trust visit. Run a reverse image search on the listing photos. To build a rental file, DossierFacile is a free French government service : nothing to pay.
“Your enrolment will be cancelled without immediate payment”
Fake emails in an institution’s colours, altered bank details, artificial urgency. No institution asks for a transfer by email with a deadline of a few hours. Check on your enrolment account, or by phone.
