All you can do is sue the business for the money they owe you. Under U.S. law, if the business is indeed a corporation (hence, the "inc."), then you cannot sue any owner(s) (i.e. shareholders) of the business personally; you can only sue the corporation itself. You would need to sue in the county in which the business is located to make sure you have "jurisdiction," or court power, over it; while there are exceptions, generally, a court only has power over defendants located within the geographic area it covers. Given the potential cost and complexity of suing someone in a different country, unless they owe you well over, say, $10,000, it is unlikely to be worthwhile to take legal action.
