Internship in France – Ameli refusing registration as non-EU student ?

Hello,

I'm currently facing an issue with opening my rights to French health insurance (AMELI), and I would appreciate some clarification on my situation.

I’m a Tunisian student, enrolled at a university in Tunisia, and I’m currently in France for an end-of-studies internship. As part of my application for health coverage, I submitted all the required documents. All were accepted except for the certificate of enrollment for the current academic year.

This document was rejected several times without a clear explanation. Recently, I finally received the following reason:
"Please provide a certificate of enrollment or school certificate from a French institution."

However, as I explained during phone calls with AMELI support, I’m not enrolled in a French university — my university is based in Tunisia. I am in France for a conventioned internship lasting more than 2 months, and I’ve submitted both my internship agreement and a payslip directly at an AMELI office.

Could you please confirm whether students in my situation — doing an internship in France while enrolled in a foreign (non-EU) university and paid at the legal minimum (4.35€/hour) — are eligible to open health rights through the French system?

Thank you in advance for your help.
