From Wikipedia: There are numerous regulations governing the practice of lobbying, often ones requiring transparency and disclosure.[7] People paid to lobby must register with the secretary of the Senate and the clerk of the House of Representatives within 45 days of contacting a legislator for the first time, or 45 days after being employed.[5][7] An exception is that lobbyists who earn less than $3,000 per client for each fiscal quarter, or whose total lobbying expenses are less than $11,500 each quarter, do not need to register.[7] Part-time lobbyists are exempt from registering unless they spend more than 20% of their working hours doing lobbying activities in any quarter. If lobbyists have two or more contacts with a legislator as a lobbyist, then they must register.[5][7] Requirements for registering also apply to companies that specialize in lobbying, or ones that have an in-house lobbyist, particularly if they spend more than $11,500 on lobbying.[7] Generally, nonprofit organizations, other than churches, are exempt from registering if they hire an outside lobbying firm.[7] Filing must be made each quarter, and a separate file is needed for each of the lobbyist's clients, and include information such as the name and title of the client, an estimate of lobbying expenses, and an estimate of income the lobbyist achieved after doing the lobbying.[7] http://en.wikipedia.org/wiki/Lobbying_in_the_United_States http://en.wikipedia.org/wiki/Lobbying_in_the_United_States
