I worked for a company that verified I9’s and provided an eVerify integration for employers. I can’t explain what problem it solved.

It was a multi-million dollar if-statement that copied the expertise of the relevant law into a permanently legacy expert system.

Doing anything besides that would be illegal. But that also means there is no cross-referencing or vendor enforcement of fraud.

It did things like check if some tax-related status code was valid for the indicated home country of emigration. It didn’t do things like check against a national database for an SSN.

It basically punished people for filling out forms incorrectly or not being able to scan a document.

We didn’t get new regulations every quarter or ever. I dunno what the point was.

Edit: the everify step technically used personally identifiable information to contact a national database.

I guess my gripe is that I didn’t see how it could prevent fraud in any way a normal HR person wouldn’t have caught if it were to be caught. It’s a duplication of a process everyone was already doing.
