Can a foreigner file a civil lawsuit against a US citizen at his country's court? Thanks.
As has already been pointed out, your question is a little vague to answer with any definitive answer, and this forum doesn't deal with non US laws.
But in general: It depends on the country and the law in that country that was allegedly violated, but in general, yes, someone in a foreign country could potentially file a lawsuit against a US citizen in his country's court.
Ooops, what Zinger said...
