swh..not so much.
There are many specific laws which apply to foreign corporations doing business with or within the United States. AND several amendments to these laws post 2002. Fr' instance, if a foreign corporation fired (or didn't hire) someone who was a U.S. National and black based on skin color and had any form of commercial dealings with the U.S., US law would apply, the case would be heard in a U.S. Court , and appropriate remedies would be applied there regardless of the individuals employment contract--or even its terms.
While a non-US national (or legal alien) would have trouble showing standing in a California court for activities occurring offshore, a U.S. National based and stationed within the U.S. and subject to U.S. law while there would not.
