I-9 Verification for Healthcare Staffing Agencies: Who Completes It, and When the Clock Starts

A nurse accepts a travel assignment on Friday and is due on a hospital unit two states away on Monday. I-9 verification for that nurse sits with her staffing agency, which the federal regulation treats as her employer [1], and if Monday counts as her first day of employment, U.S. Citizenship and Immigration Services, or USCIS, expects the agency's section of the form to be completed by Thursday [2].

Two rules bear directly on agency work. USCIS lets a staffing agency choose which date counts as the first day of employment, and the choice moves the deadline [2]. The second is newer: on October 14, 2026, the Department of Homeland Security made final its rule ending automatic extensions on renewal for Employment Authorization Documents in certain categories [3]. For renewals filed on or after October 30, 2025, the expiration date printed on the card is now the reverification deadline unless a law or Federal Register notice provides otherwise [4].

The staffing agency is the employer for I-9 verification

Every U.S. employer completes a Form I-9 for every person it hires, citizens included [5]. For contract labor, the federal regulation at 8 CFR 274a.1(g) names which employer that is: "In the case of an independent contractor or contract labor or services, the term employer shall mean the independent contractor or contractor and not the person or entity using the contract labor" [1]. USCIS's Handbook for Employers M-274 tells businesses not to complete the form for workers employed by temporary agencies or employee leasing firms and providing labor to them [6].

One limit still applies to the facility. The handbook's answer on contractors adds: "However, you may not use a contract, subcontract, or exchange to obtain the labor or services of an employee you know is unauthorized to work" [7].

The form is federal and the same in every state, which sets it apart from licensing across state lines. None of the federal guidance cited here has a separate rule for healthcare. The background check that sits next to I-9 verification is a separate record with its own rules.

The three-business-day clock starts on a date the agency chooses

Section 1, the employee's part, is due "no later than the employee's first day of employment" [8]. Section 2 is the employer's part, completed by examining the documents the employee presents within "three business days of the date employment begins" [2].

The handbook's Section 2 guidance has one sentence written for staffing agencies: "Staffing agencies may choose to use either the date an employee is assigned to the employee's first job or the date the new employee is entered into the assignment pool as the first day of employment" [2].

The two options can put the deadline weeks apart. Counting entry into the pool starts the three business days at that entry, possibly well before any shift. Counting the first assignment starts them on the assignment, which for a traveler may be the day she reports to a facility in another state. The handbook does not say whether an agency must apply one choice to every worker, and no public guidance answers that.

Short work has no three-day window at all. "If an employee will work for less than three business days, Sections 1 and 2 must be fully completed at the time of hire (in other words, by the first day of employment)" [6], and the regulation bars accepting a receipt in place of a document for employment that short [9]. That is the rule to check against per diem bookings and short local contracts.

Immigration and Customs Enforcement, or ICE, which inspects employers' forms, lists failing to complete Section 1 or Section 2 on time among substantive violations [10].

Examining documents by video requires E-Verify at each hiring site

The harder case is a clinician who never visits an agency office. The handbook's default is plain: "In general, you or your authorized representative must review the employee's documentation in their physical presence" [2].

An authorized representative near the clinician

An employer may use "any person you choose" as an authorized representative to complete Section 2, notaries public included, and USCIS requires no contract with them [6]. The agency remains "liable for any violations in connection with the form or the verification process, including any violations committed by the authorized representative acting on your behalf" [6]. That wording does not exclude a client facility's staff, and the handbook says nothing about facilities in the role.

Remote examination for E-Verify employers

The alternative procedure for remote examination is open to employers that participate in E-Verify in good standing, which includes enrollment "with respect to all hiring sites that use the alternative procedure to remotely examine documents" [2, 11]. The employee sends copies of the documents, then presents the same documents in a live video interaction, and the employer keeps copies of all of it with the form [11, 12].

The form has a box in Section 2, and another in Supplement B, to record that the alternative procedure was used [11, 13]. ICE's August 2026 fact sheet lists two substantive violations tied to that box: leaving the box blank when the procedure was used, and checking it without being "an active E-Verify participant or registered in a DHS Non-E-Verify Remote Document Examination Form I-9 program" [10]; the USCIS page on remote examination describes E-Verify participation as the condition and mentions no other route [11].

The offer has to be consistent by site: "If you choose to offer the alternative procedure to new employees at an E-Verify hiring site, you must do so consistently for all employees at that site" [11]. It may be limited to remote hires, provided that practice is not adopted for a discriminatory purpose and employees are not treated differently based on citizenship, immigration status or national origin [11]. E-Verify's user manual defines a hiring site as a location associated with a memorandum of understanding where employees are hired and complete Form I-9 [14]. No public source applies that definition to a recruiter working from home, or to a traveler who never sets foot in an agency office.

Reverification now falls on the printed expiration date unless an extension applies

Reverification is due "no later than the date employment authorization expires", and the handbook states what follows: "You cannot continue employing a person who does not provide proof of current employment authorization" [15]. For a traveler, that date can land in the middle of an assignment.

The October 30, 2025 cutoff turns on the renewal's filing date. Applications filed on or after it carry no automatic extension unless a law or Federal Register notice provides otherwise, while applicants who filed earlier under certain eligibility codes may still qualify for one of up to 540 days if they meet certain requirements [4].

Tracking those dates has limits that run the other way. "Reverification is never required for U.S. citizens or noncitizen nationals", nor when U.S. passports, passport cards, Permanent Resident Cards or List B documents expire [16]. USCIS's list of practices to avoid includes "Don't request specific documents for reverification" [17].

Clinicians who come back after a gap

A traveler rehired within three years of the original form can be recorded on Supplement B or on a new form; after three years, a new Form I-9 is required [18]. The handbook treats some interruptions as continuing employment: it asks whether the employee "has a reasonable expectation of employment at all times", and its examples include temporary layoff for lack of work and seasonal employment [19]. It does not apply that test to the weeks between staffing assignments, and no public source settles whether a traveler who starts a new contract a month after the last one is continuing in employment or rehired.

How long the form is kept, and what ICE asks for at inspection

Retention runs "three years after the date of hire, or one year after the date employment ends, whichever is later" [20]. For anyone who worked less than two years, USCIS counts the three years from the date in the First Day of Employment field [20], so for those workers the agency's first-day choice also sets the retention clock.

An inspection starts with a Notice of Inspection and at least three business days to produce the forms [10]. Technical or procedural failures, including use of a form version that was not current when first completed, get at least ten business days to correct before they become substantive [10].

The civil penalty for a paperwork violation is "not less than $288 and not more than $2,861 for each individual with respect to whom such violation occurred", under 8 CFR 274a.10 as shown on the Electronic Code of Federal Regulations, up to date as of November 9, 2026 [21].

Where Credentially fits around the Form I-9

I-9 verification and any E-Verify case sit outside Credentially. Its part is the pre-employment document collection an agency runs in the same week. As documents arrive, Credentially reads each file, captures the relevant details and matches it to the requirement it satisfies, and your team sees what is complete and what still needs review without checking every page by hand.

After placement, Credentially monitors license status and document expirations in the background, alerting your team when something changes or needs action. Each check is recorded as it happens, so ongoing compliance does not depend on someone remembering to look; the document expiration tracking page shows how. Reverification is part of the Form I-9 process, so it also sits outside Credentially.

Start with the work authorization dates due in the next 90 days

The I-9 verification check to run first is a list: the active clinicians whose Form I-9 shows an employment authorization expiration date in the next 90 days, leaving out the documents the handbook says are never reverified. Mark which of them filed a renewal on or after October 30, 2025, because under the current rule a timely filing on its own no longer moves their date [4]. If the license dates around them depend on someone remembering to look, book a demo to see how license status is monitored.

Frequently asked questions

Who handles I-9 verification for a travel nurse, the staffing agency or the hospital?

The staffing agency. Federal regulation defines the employer for contract labor as the contractor "and not the person or entity using the contract labor", and USCIS tells businesses not to complete the form for temporary agency workers. A facility still may not use a contract to obtain labor it knows is unauthorized [1, 6, 7].

When does the I-9 verification deadline start for a staffing agency?

The three-business-day deadline for Section 2 runs from the first day of employment, which USCIS lets staffing agencies set as the date of the first assignment or the date the worker enters the assignment pool. Work lasting less than three business days needs both sections done by the first day [2, 6].

Can a staffing agency complete I-9 verification remotely by video?

Yes, if the agency participates in E-Verify in good standing at the hiring sites using the alternative procedure. The employee sends copies, then presents the same documents in a live video interaction. The agency keeps the copies and checks the alternative procedure box on the form. A hiring site that offers the procedure must offer it consistently, though it may limit it to remote hires on a nondiscriminatory basis [11, 12].
