My organization has found it 100% effective, but that’s merely an anecdote, since we’re fairly small.

This site explains has more solid data:
https://www.uscis.gov/e-verify/about-program/performance

To wit:
98.94% of cases are found to be work-authorized immediately.
0.16% of cases were found to be initially mismatched, but corrected. (This is why the EEOC warns not to immediately fire mismatched employees.)
0.61% of cases were found to be mismatched, and not contested.
0.01% of cases were contested, and found to be mismatched. (1 in 10,000 people disagreed with final findings that they are not work authorized.)
These cases account for 25 million hires in the past year, or 50% of all hires.
Illegal aliens constitute 12% of hires not made through E-Verify.

Thanks for your excellent reply.

Some of the pro illegals small business people try to say this data is worthless.

Yet good business owners swear by it.

Also, it helps young legal Hispanics and Hispanic Americans to find out that their SS#’s have been hacked.
We have a couple tell us that the E verify told them their SS#’s had been hacked.

So the tool is there if employers want to use it.

Thanks again.
