How Long Does an Employer Have to Complete Form I-9?

Your new hire starts Monday. She lives in Bend, your HR team sits in Portland, and nobody has looked at her documents yet. By Thursday you’re out of compliance, and most employers don’t realize the clock started the moment she began work for pay.

How long does an employer have to complete Form I-9? Three business days from the employee’s first day of work for pay, for Section 2. Section 1 is due earlier, on or before day one.

Below you’ll learn exactly when each section is due, how to count the three days, how to handle a remote hire who can’t reach your office, and what a notary can and cannot do on the form.

How Long Does an Employer Have to Complete Form I-9?

An employer must complete and sign Section 2 of Form I-9 within three business days of the employee’s first day of work for pay. If the job will last fewer than three business days, Section 2 must be completed no later than the first day of employment. The employee must complete Section 1 on or before day one.

USCIS uses a clean example in the Handbook for Employers: an employee who begins work for pay on Monday needs Section 2 completed on or before Thursday of that week. 

The trigger is the first day of work for pay, not the offer date and not an unpaid orientation. That distinction matters, because HR teams routinely start the clock from the wrong event and lose a day.

When Is Section 1 Due and When Is Section 2 Due?

The form splits responsibility between two people with two different deadlines, and mixing them up is the most common source of a late I-9.

Two details in that table are easy to miss. Only the employee may complete Section 1, so an HR coordinator filling it in on their behalf creates a defect. And the short-job rule collapses both deadlines onto day one, which catches employers running seasonal or event staffing.

Staffing agencies get one piece of flexibility. USCIS allows them to treat either the date an employee is assigned to their first job, or the date the employee enters the assignment pool, as the first day of employment.

How Do You Count the Three Business Days?

Business days mean the days your business actually operates. If you run Monday through Friday, weekends don’t count. If you regularly operate Saturdays and holidays, those days count toward the three.

Here’s where employers get burned. There has been longstanding debate over whether the hire date itself counts as day one, and USCIS guidance has not settled it cleanly in every context. Immigration counsel generally advises the conservative reading.

Count the hire date as day one and finish early. The safest practice is simpler still: ask the new hire to bring their documents on day one and complete Sections 1 and 2 together. That removes the counting question entirely.

Can You Complete Form I-9 Before the Employee’s Start Date?

Yes, and for remote hires you probably should. Once the candidate has accepted the job offer, both Section 1 and Section 2 can be completed at any point up to the deadline.

The three business days is a maximum, not a required waiting period. Nothing stops you from finishing the entire form the week before someone starts, and scheduling breathing room is exactly why employers use that window.

One firm limit applies. You may not ask someone to complete Section 1 before they have accepted an offer. Handing Form I-9 to a candidate during interviews is a violation on its own, regardless of how the timing works out.

What Happens When Your New Hire Works Remotely?

The deadline doesn’t move because your employee is three hundred miles away. What changes is who does the examination.

Federal rules let you designate an authorized representative to examine original documents in the employee’s physical presence and complete Section 2 on your behalf. USCIS places almost no restrictions on who that person can be. It can be a colleague near the employee, a notary public, an attorney, or a professional verification service.

The one absolute rule: the employee cannot verify their own documents. An I-9 where the new hire completed both sections reads as missing Section 2 during an audit.

Here’s the workflow that keeps you compliant:

1. Identify a representative near the employee before their start date, not on day three.
2. Send written instructions covering what to examine, how to fill in Section 2, and how to return the form.
3. Include the Lists of Acceptable Documents from the current Form I-9 so the representative isn’t guessing.
4. Have the employee and representative meet in person with original, unexpired documents.
5. Get the completed form back by scan or mail before your three-day window closes.
6. Review Section 2 yourself for missing dates, document numbers, and signatures before filing.

That review step is not optional busywork. The employer stays liable for every error the representative makes, so a five-minute check protects you from a defect that surfaces years later.

Does a Notary Have to Notarize Form I-9?

No, and this is the single most misunderstood point in the whole process. Form I-9 is never notarized. There is no notarial act involved and no seal belongs anywhere on the form.

When a notary completes Section 2, they are acting purely as your authorized representative. They’re doing the same job an office manager would do, which is looking at original documents and attesting that the documents reasonably appear genuine and relate to the person presenting them.

A notary who stamps Form I-9 has misunderstood the assignment. The seal adds no legal weight, and in some states applying it where no notarial act occurred creates its own problem.

This is why it pays to use a notary who has done I-9 work before. Ours complete Section 2 as a designated representative and leave the stamp in the bag, which is a different skill from the notary and witness services most people call us for.

When Can You Examine Documents Over Video Instead?

Since August 2023, DHS has authorized an alternative procedure allowing remote document examination by live video. It is not open to everyone.

To use it, you must be enrolled in E-Verify and in good standing. The employee transmits copies of their documents to you first, then presents those same documents during a live video interaction. You retain copies and check the alternative procedure box on the form.

If you’re not in E-Verify, this option is closed to you and the in-person examination requirement stands. That’s the situation most small and mid-sized Oregon employers are in, which is why the authorized representative route remains the practical answer.

One clarification that saves confusion. Remote online notarization is not the same thing and does not satisfy Form I-9 requirements. RON is a notarial process under state law, while I-9 document examination is a federal employment rule. They don’t substitute for each other.

What Happens If You Miss the Three-Day Deadline?

Complete it as soon as you discover the gap. A late Section 2 is better than a missing one, and demonstrating a good faith effort to comply matters.

What you must never do is backdate the form. Entering a date that makes the completion look timely turns a paperwork violation into something far more serious, and auditors are practiced at spotting it.

Correct errors the approved way instead. Draw a single line through the incorrect entry, write the correct information, then initial and date the change. Attach a brief signed note explaining what happened and when you caught it.

Immigration enforcement assesses penalties per form, and they escalate with the number of violations and the employer’s history. A file of late or incomplete I-9s multiplies quickly across a workforce, which is why the deadline is worth systematizing rather than remembering.

What Mistakes Do Employers Make With I-9 Deadlines?

Starting the clock at the offer date. The trigger is the first day of work for pay. Offer letters, background checks, and unpaid orientation don’t start it.

Letting HR complete Section 1. Only the employee may fill in Section 1. A preparer or translator can assist, but they sign the preparer certification rather than completing it as the employee.

Telling the employee which documents to bring. Employees choose what to present from the Lists of Acceptable Documents. Specifying documents is a discrimination issue, not just a paperwork one.

Accepting photocopies. The representative must examine original documents, with certified copies of birth certificates as the narrow exception. A photo of a driver’s license on a phone doesn’t qualify under the in-person method.

Assuming a notary knows the process. Most notaries have never completed a Form I-9 and will reach for the stamp out of habit. Send written instructions every time.

Waiting until day three to find a representative. Coordinating someone in another city takes longer than you think. Line them up the week the offer is accepted.

Who can be an authorized representative for Form I-9?

Almost anyone the employer designates, including a notary, an attorney, or a local colleague. The employee cannot verify their own documents.

Does Form I-9 need to be notarized?

No. A notary completing Section 2 acts as an authorized representative and should not apply a seal to the form.

Can I verify I-9 documents over video?

Only if you’re enrolled in E-Verify and in good standing, using the DHS alternative procedure. Otherwise examination must be in person.

What if I miss the three business day deadline?

Complete it immediately and note when the error was found. Never backdate the form.

Who is liable if the authorized representative makes a mistake?

The employer. Liability does not transfer to the representative, so review Section 2 before filing.

How Long Does an Employer Have to Complete Form I-9? The Short Answer

Three business days after the first day of work for pay, with Section 1 done on or before day one. Shorter still if the job runs under three business days, because then everything lands on day one.

Remote hiring doesn’t change the deadline, only the logistics. Designate an authorized representative early, give them written instructions, and check their work before you file it.

And remember the part almost everyone gets wrong: Form I-9 is not a notarized document. If you send a new hire to a notary, make sure that notary knows they’re completing Section 2 as your representative, not performing a notarization.
