Form I-9 looks simple. It's two pages. How hard can it be? Ask the employers who've paid tens of thousands in fines for getting it wrong. After 30-plus years advising companies on employment verification, here's the practical guide I wish every HR manager had on day one.
The rule is straightforward: every U.S. employer must complete a Form I-9 for every person hired for employment in the United States. Citizens, green card holders, visa holders — everyone. No exceptions for company size, and no exceptions because someone "looked American."
Timing matters. The employee completes their section by the end of the first day of work. You, the employer, must complete your section — including physically examining their documents — within three business days of the start date. Miss that window and you've already got a violation, even if everything else is perfect.
The document examination is where most employers stumble. You must examine the actual documents the employee presents — a passport, or a driver's license plus a Social Security card, or any other acceptable combination from the official lists. The documents must reasonably appear genuine and relate to the person presenting them. You're not expected to be a forensic examiner, but you can't just glance and check a box either.
Can you verify documents remotely? This changed recently. DHS now allows employers enrolled in E-Verify to use an alternative procedure for remote document examination instead of the traditional in-person physical inspection. If you're not in E-Verify, you still need someone physically present with the employee — you can designate an authorized representative, like a notary or a local manager, to complete the verification on your behalf. Webcam-only review without the authorized alternative procedure doesn't cut it.
Independent contractors are not your employees for I-9 purposes — the contracting company handles their own verification. But beware: you can't use contractors as a dodge to employ unauthorized workers. If you know someone isn't authorized to work, no paperwork trick protects you.
Reverification trips people up too. When an employee's work authorization expires, you must reverify — but never reverify a U.S. citizen or green card holder's documents just because you feel like it. That's document abuse, and it carries its own penalties.
Penalties are serious: thousands of dollars per violation for paperwork errors, and far worse for knowingly employing unauthorized workers. And in the current enforcement climate, I-9 audits are not rare events. They happen to small businesses, not just big corporations.
My advice: audit yourself before the government does. Review your I-9s annually, fix errors properly (never backdate), train everyone who touches the process, and consider E-Verify enrollment. An hour of prevention beats a world of fines.
