> The Immigration Reform and Control Act of 1986 (IRCA) makes it illegal for an employer to discriminate with respect to hiring, firing, or recruitment or referral for a fee, based upon an individual's citizenship or immigration status. The law prohibits employers from hiring only U.S. citizens or lawful permanent residents unless required to do so by law, regulation or government contract

Look, like it or not, we all have to work with our HR apparatus. If I have the choice between running their department and keeping mine functional, I have to accept that they at some level know what they are doing. Not to mention, when your HR head has the JD, and you don't, what you think you know is outweighed by their credential.

Now, was I misinformec by an HR person during my time as a hiring manager? Maybe. But guess what, I didn't control their pipeline, and I had work to make sure got done. I'll definitely be adding HR people to my list of groups to talk to when interviewing companies interested in hiring for a hiring manager position though, because the sheer amount of hell that experience came with was beyond unreasonable.

Not just crap. It’s misinformation—whether direct or indirect—motivated by those who’d benefit from believing this.
