Why would you want to attempt too wash money through a U.S. corp? Your looking to get royally fucked by doing this. Why not just have all your earnings paid into an offshore company that you would indirectly own through another offshore company. Pay yourself a modest income as an employee/contractor of the first company so as not to attract the attention of the taxman and then payout the rest of your funds from the 1st company to the 2nd offshore company. You'll have to be careful though because if the taxman finds out that your living beyond your means they will turn your life into a living hell well they try to track where the money is coming from. After you've built up a nice nest egg in the 2nd company just move out of your country for a few years and then move back and your money is washed and legit.
Again, avoid involving the U.S. in this scheme. Aswell, the above mentioned structure is a very simple one; too really hide the money you would have to have a much larger network of offshore companies to run the money through.
