USCIS has released some interesting statistics today on recent H-1B adjudications,.

Below is a snippet of key points from Forbes.com link 

In FY 2018, USCIS denied 80% of the H-1B petitions for new (initial) employment for Capgemini, a French multinational, 61% for U.S. company Cognizant, and between 34% and 54% for IT services companies Syntel, Infosys, Mindtree and HCL America. To put these figures in perspective, major U.S. tech companies, including Amazon, Facebook and Apple, had 1% or 2% of their new H-1B petitions denied in FY 2018.

USCIS says 60% of all completed H-1B cases received a Request for Evidence in the first quarter of FY 2019, which companies consider a high level that adds time, cost and uncertainty to the process. FY 2018 data show even H-1B extensions for existing employees were denied about 25% of the time for many IT services and consulting companies, even though such employees had been previously approved for visas.
