Before the 12 months expiration, you must convert to a French Driving License. France has reciprocal agreements with only 18 specific US states, meaning only licenses issued by these states can be exchanged for a French license without retaking the written or practical driving tests. These eligible states are Arkansas, Colorado, Connecticut, Delaware, Florida, Idaho, Illinois, Iowa, Maryland, Massachusetts, Michigan, New Hampshire, Ohio, Oklahoma, Pennsylvania, South Carolina, Texas, Virginia, and Washington DC.

12 months will be verified because you will need a short-term visa to remain in France
