Hi, Frogger!
I'm no authority on this subject, but you may have difficulty for this scholarship due to the eligibility criteria. Applicants must:
1. Be aged 30 years old or less in the selection year.
2. Have a single nationality from a developing country deemed an "emerging country" by the French state department, especially those in Asia and Latin America, for example, currently under-represented among the student population in France.
The scholarship is sponsored by the French government (French ministry of Foreign Affairs), but I think that you apply through HEC. In other words, HEC acts as a filter or middleman in the process. That was my impression, at least.
I'm sure that you have already seen this, but here is a brief description of it just in case. If you still have any questions, contact the HEC admissions department.
