Support by a student on a work-study contract

Hello dear community

My little sister residing in Cameroon has been admitted to a public university with partial exemption. I am a student on an apprenticeship contract and earn above the minimum wage, which is €2000 gross and €1855 net. I would like to know if I can support her with €615/month for a year. I live alone in rented accommodation without any expenses.

A Campus France YouTuber told me: « a student cannot provide financial support even if they have millions, » I didn’t understand why.

I also thought about going to see my bank manager in France to get an AVI (Attestation de Virement Irrévocable) for her, but I’m not sure if it’s possible.

Thank you for your responses and especially for your feedback.
