> I dont' think it's possible to have an trans-national employment contract (which labor laws would the contract observe? The French ones or the US ones?)

Those contracts are of course possible and exist - although rare due to paperwork hell you need to go through. The labor law of the employee's country is observed and they usually need to handle pension/health contributions on their side. In most of EU at least.

It is true though that most EU countries also demand that you open a local subsidiary once you have a certain amount of employees there (~5-10).
