Various agencies conduct the investigation of immigration fraud under the U.S. government, including the U.S. Citizenship and Immigration Services (USCIS), the Department of Homeland Security (DHS), and Immigration and Customs Enforcement (ICE). These agencies work together to investigate and prosecute individuals and organizations involved in immigration fraud or misrepresentation.

USCIS is responsible for processing immigration applications and petitions, and they have a Fraud Detection and National Security (FDNS) unit dedicated to detecting and preventing immigration fraud. The FDNS conducts site visits and interviews to verify information provided on immigration applications and petitions.

DHS is responsible for enforcing immigration laws and investigating immigration-related crimes, including fraud and misrepresentation. DHS agents work with other law enforcement agencies to investigate and prosecute individuals involved in immigration fraud.

ICE is responsible for investigating and enforcing immigration-related crimes, including immigration fraud and misrepresentation. ICE agents have the authority to arrest and detain individuals suspected of immigration fraud. They work with other law enforcement agencies to bring criminal charges against those involved in immigration fraud.

In addition to these agencies, the U.S. Department of Justice (DOJ) also has a role in investigating and prosecuting immigration fraud. The DOJ’s Office of Special Investigations (OSI) is responsible for investigating individuals and organizations suspected of committing immigration fraud. They work closely with other law enforcement agencies to bring criminal charges against those involved.
