https://www.uscis.gov/sites/default/files/USCIS/Resources/Re... is pretty good data for 2018.

You can see that non-consultancy firms like Amazon, Microsoft, Apple, Google and Facebook all have approval rates close to 99%.

There's a large difference between IBM Corporation (approval rate 92%) and IBM India Private Limited (approval rate 82%). The difference is even greater if you look only at initial approvals vs. denials (IBM India 62 vs. 60, IBM 268 vs. 3). I wonder what the cause is.
