Through the USCIS Fraud Fee, investigators are being sent to employers of H-1B holders.  Investigators are looking to verify whether the
companies are real operating business entities and whether the person being sponsored is a
"legitimate" employee.  Of particular interest are two types of fraud, "(1) a foreign worker who falsifies an application and claims to work for a
company that he does not work for and/or (2) a company that is falsifying an
application. He indicated that he wants to meet the H-1B worker and see some
form of identification to prove that the employee is who he says he is."  (Quoted from AILA InfoNet 7/31/09).  Source AILA InfoNet.
