Thank you,will do.Check with your local consulate (since the health insurance is required as a condition of the visa and must be obtained before you enter France). It can depend a bit on the type of visa you are going for.
Some visas (student visas, for example) require you to have insurance that will cover medical evacuation back to your home country in the event of a serious accident or illness. Other visas require you to obtain health insurance that is roughly equivalent to the French national program. The first kind of insurance is travel insurance. The second is "expat health insurance" and should be obtainable through most of the large, international companies (AXA, Bupa, Allianz, Swiss Life, etc. etc.).
