A friend of mine was telling me about a law in the USA that states if you take an over-seas job, when you return to the USA you are not allowed to work for an operator that carries US Mail for something like 4 or 5 years. Can anybody confirm this or have any details about this law? It would be great to make some money over-seas for a few years, but I would hate to come back and not be able to get a job.
