The airport at Geneve is built on both French and Swiss land, altough it's a "Swiss" airport....If you wish you can leave by a side door and pass by French customs etc directly into France. Don't recommend it because the French door is not easy to find and when you leave you are in what appears to be a small regional airport.
I'm sure othershere have the same problem as the OP ?
