IMPORTANT: Also please be aware that these days the USCIS is conducting H1-B administrative site visits primarily to check whether there is really an actual employer, whether the employer knows it filed the petition, who paid the USCIS fees and whether the beneficiary is doing the work and receiving the wage indicated on the petition. H-1B visits are done on a post-adjudication basis, and are randomly selected. Each employer should receive only one such visit, but may receive different visits for different sites.
As part of on-going anti-fraud measures, the USCIS has implemented a program known as Validation Instrument for Business Enterprises (VIBE). It is a web-based tool that allows the USCIS to corroborate certain basic information about a company during adjudication of employment-based visa petitions. VIBE uses commercially available information to verify the contents of employment-based immigration petitions. Use of this program is becoming evident in the content of requests for evidence (RFEs). Thus, employers need to be aware of the VIBE and, take steps to update their company information with Dun and Bradstreet (D&B) who is the information provider for the VIBE program. D&B is a supplier of commercial information on businesses. In order to avoid RFEs due to outdated or inaccurate information in D&B's records employers should review their D&B company report and ensure that D&B's database is accurate. There is no fee to update company information. If a company finds that D&B does not have its information at all, it may request assignment of a D&B number.
