A Miami Department of Homeland Security worker who was training to become a special agent has been accused of charging non-U.S. citizens up to $12,000 for fraudulent documents that allow them to work in the United States, officials said Nov. 13.

Federal agents arrested Isidro Guerrero Fernández, 32, Nov.12 at the Federal Law Enforcement Training Center in Glynco, GA, according to a criminal complaint, the Sun-Sentinel reported.

“People who misuse their positions to commit crimes will find no sympathy in this office," John Bulger, director of the Miami office of U.S. Citizenship and Immigration Services, said in a statement.

Guerrero has worked with CIS, formerly the Immigration and Naturalization Service, since March 1998. He transferred to the Employment Authorization Documents department in CIS's Miami office in April 2002, and on Nov. 6 began training in Georgia to become a Homeland Security special agent.

Investigators said Guerrero worked with a Chilean man, Miguel Raggio, to get immigrants to pay between $6,500 and $12,000 for employment authorization cards, which non-U.S. citizens need to work in the United States. The cards can be bought legally from CIS for about $110.
