From the Overseas Private Investment Corporation (OPIC), a federal agency specializing in funding U.S. businesses for overseas enterprise, comes what claims to be a fairly complete rundown of Washington agencies that can help in establishing offshore ventures. Some truly are secret: the Federal Bar Association, for example, gives free consultations to small businesses on legal questions of international trade and investment. Even more useful are the details of OPIC's own programs, including feasibility-study participation and direct loans of up to $4 million to small businesses (defined as companies having revenues or net worth less than that of the smallest company on the Fortune 1,000).
