Check with your local and state child support enforcement agency. Many state child support enforcement agencies have agreements with foreign countries to recognize child support judgments made in either country. You will need the same kind of information as is required for enforcement in this country and as much specific address information as you can find. If the non­custodial parent works for an American company, wage withholding may work even if the country he lives in does not have any agreement to enforce a United States court order.
