The Freedom of Information Act states that anybody has the right to seek information from the government. It includes both citizens and non-citizens of the United States. You can write to any ministry or agency of the government to seek any information and the law mandates such government agency to release such document if it is available and fit for public access. If the document is classified or secret you will need a court judgment to access it because it is under the privacy act. So you can write to the SEC or treasury department, pay the stipulated fees, keep checking on the status of your request and hopefully you can get some details.
