In the recently issued USCIS Ombudsman's 2010 Annual Report to Congress, the Ombudsman notes that the CIS has entered into a contract with Dun and Bradstreet to gather information about H1B employers:

"Technology that employer stakeholders are especially monitoring is the Validation Instrument for Business Enterprises (VIBE). Through use of public, third-party source information, USCIS plans for VIBE to streamline adjudication of employment-based petitions and combat fraud by providing adjudicators with the ability to verify the “financial viability and current level of business operations”
of petitioning employers.

USCIS awarded the contract to develop VIBE to Dun and
Bradstreet in September 2009 and, as of this writing, the system is undergoing testing.59 USCIS scheduled deployment for full use in all service centers to occur this summer.

VIBE should enable USCIS to focus on whether the individual meets the standards for the benefit sought rather than on whether the petitioner is a bona fide employer. While USCIS anticipates that the use of VIBE may result in a reduction of Requests for Evidence (RFEs) or more tailored RFEs due to adjudicators’ reliance on this information, some stakeholders are awaiting more information on how USCIS will handle glitches such as employers that have more than one listing in the database or how employers can make corrections when USCIS relied on information that is outdated or otherwise inaccurate."
