Who or what agency do I file a claim to start an investigation against
a corporation that hires illegal and untrained immigrants to perform
work when the U.S. professional employees refuse to accept any
additional jobs because they are not being paid for work performed? 
Is it a federal agency or Florida Labor or Workforce Commission?  Is
there a web-site with a form I can fill in and submit to implement the
investigation into the corporation?  If not, how do I contact the
agency?

Hello,

According to the Immigration and Naturalization Service, you should
contact the closest field office. The following offices are in
Florida:

7880 Biscayne Blvd., 9th Floor
Miami, FL 33138
(305) 762-3610

4121 Southpoint Blvd.
Jacksonville, FL 32216
(904) 232-3156

9403 Tradeport Drive
Orlando, FL 32827
(407) 855-4418

301 Broadway
Riviera Beach, FL 33404
(no phone number listed)

5524 W. Cypress St.
Tampa, FL 33607-1708
(813) 637-3050

For more information on the topic, see
(http://www.ins.gov/graphics/howdoi/illegal.htm).

There is a Florida Department of Business and Professional Regulation
(http://www.state.fl.us/dbpr/). However, they would only handle issues
dealing with businesses that require special licenses from the state,
such as accountants and real-estate agents. The Florida Department of
Labor recently was eliminated. Because immigration is a federal issue,
you should focus your energies on the federal government, notably the
INS.

I hope this answer meets your needs.
