Hello, I am thinking about applying for the MBA luxe management program in Paris. It costs about 27000 Euros (plus living expenses), which I don't have. Any ideas on how to get funding? I don't know if I'd be eligible for student loans (I'm in medical school right now. . .I know, completely different background!). Should I appeal to the French government or write companies asking for funding? Any ideas?

Do you fulfil the application requirements for the MBA? Then you should be eligible for a loan, but it might be difficult to present a good argumentation.
Usually companies will give you funding only if you can establish that you will do a good MBA, and are an interesting candidate for them afterwards. This evaluation is made on the basis of your former achievements
Or you can get a scholarship or funding, if you have a certain background. As an example you might get funding if you are from an African country with which France has certain agreements.

In all cases I think you have to prove that you are performing over average, and justify why you do this radical change of career, or better explain, that this is the best you can do and will leed to an incredible business career..
