I second BokerTov's advice though, talk to a specialist tax advisor. US tax is too damned complicated and the penalties for errors too high to risk making mistakes. FBAR penalty alone could be as high as $10,000 for failure to file per violation for nonwillful violations that are not due to reasonable cause. It gets much more expensive if it's deemed a wilful violation.
