As of October 2026, Wyoming has no E-Verify law. No statute requires private employers, the state, counties, municipalities or school districts, or contractors on public works to use it. Wyoming lawmakers have taken up immigration-related employment bills in 2009, 2011 and 2025, and none advanced. Federal rules are the whole story for most Wyoming employers: Form I-9 for every hire, and E-Verify when a federal contract requires it.
Wyoming's neighbors are the complication. Montana now inspects employers' verification records, Utah requires E-Verify from large private employers, Nebraska requires it on public contracts, and Idaho and Colorado have no mandate. Energy, pipeline and construction work routinely crosses those lines, and a crew that moves from Gillette into Montana or from Evanston into Utah can change its employer's obligations.
Not legal advice. Sources and method, current to October 2026: a text search of all 41 titles of the Wyoming Statutes, as the Legislative Service Office publishes them, found no use of "E-Verify" or "employment eligibility verification." The Legislature's records for every House and Senate file from 2010 through 2026, plus the 2009 file discussed below, were screened for immigration and verification bills. Local government and agency contracts were outside our review, so have counsel confirm anything you plan to rely on.
Wyoming by employer type
| Employer | Wyoming rule | What still applies |
|---|---|---|
| Private employers, including energy, ranching and tourism | No E-Verify requirement | The federal I-9 baseline only |
| State agencies, counties, municipalities, school districts | No E-Verify requirement | The same baseline; enrolling is a local choice |
| Contractors on state and local public works | No E-Verify requirement | Whatever the bid documents add |
| Federal contractors and subcontractors | Federal requirement | Clause 52.222-54 when the contract carries it |
The bills that did not pass
| Bill | What it would have done | What happened |
|---|---|---|
| HB 103 (2009), "Illegal immigration," Rep. Illoway | Among many provisions, required certain employers to verify the citizenship status of employees and made hiring unauthorized aliens, or failing to verify, an offense | Died in House committee, March 4, 2009 |
| HB 94 (2011), "Illegal immigration," Rep. Illoway | Required employers to participate in E-Verify and prohibited employing unauthorized aliens; proof of E-Verify use would create a rebuttable presumption that the employer did not knowingly employ one | Returned by House committee without action, March 2, 2011 |
| HB 163 (2025), "Prohibiting employment of unauthorized aliens," Rep. G. Brown and others | New W.S. 6-7-201: misdemeanor to employ or contract with an unauthorized worker; $1,000 fine for a first offense, $5,000 after; each worker a separate offense; no E-Verify provision | Not considered for introduction; died February 3, 2025 |
The 2025 bill is worth a closer look because it took a different route from the earlier ones. Instead of requiring a verification method, it would simply have made unauthorized employment a state crime and left employers to decide how to avoid it. Its exceptions covered workers with a valid, current visa or other work authorization and workers lawfully present who were renewing their status under federal law. It also reached anyone who "otherwise contract[s] for services" with an unauthorized worker, which could have touched independent-contractor relationships that Form I-9 does not cover. The 2026 budget session produced no comparable bill.
A 2025 law that is not about employment, but gets confused with it
House Bill 116 of 2025 did pass. It became W.S. 31-7-143, which treats a driver's license or similar document issued by another jurisdiction to an unauthorized alien, or marked to show the holder did not prove lawful presence, as invalid for driving in Wyoming. That is a traffic law. It does not change Form I-9, which is governed by federal rules: USCIS says an employer may accept a state driver's license that carries a restrictive notation as a List B identity document. Because List B proves identity only, the employee still presents a List C document, such as an unrestricted Social Security card, for work authorization. Rejecting an out-of-state license that otherwise meets the List B rules would risk a federal document-abuse claim. See I-9 List A, B and C documents.
The neighbors, and where Wyoming crews meet them
| State | Rule | Typical Wyoming exposure |
|---|---|---|
| Montana | A records law since July 1, 2025: each new hire's file must hold an E-Verify result or an I-9 plus copies of the documents shown; audits, and fines that reach $2,500 per worker for repeat violations | Powder River Basin and Bighorn crews working in southeastern Montana |
| Utah | Private employers with 150 or more employees must use a status verification system (Utah Code 13-47-201) | Larger Evanston and southwest Wyoming employers with staff in Utah |
| Idaho | No E-Verify statute; 2026 bills for a public-sector mandate failed | Star Valley and Jackson-area employers with Idaho staff: no added duty |
| Nebraska | Public employers and contractors on public services contracts | Cheyenne-area firms bidding Nebraska public work |
| Colorado | No mandate since 2022 | None |
| South Dakota | Nothing enacted; House Bill 1209 failed at the conference stage in March 2026 | None for now |
Montana deserves the most attention. Its records rule applies to each worker employed there, and the state can require the books within three business days of asking. A Wyoming company with a Montana crew should pick one of the two Montana methods for those workers and keep the files ready.
Ranches, resorts and rigs: Form I-9 over long distances
Without a state mandate, the federal Form I-9 is what an auditor would actually look at, and Wyoming's distances make Section 2 the weak point. A ranch hand hired by phone, a resort worker arriving in Jackson the night before a season opens, or a hand reporting directly to a rig two hours from the office all need their documents physically examined within three business days of starting. The usual Wyoming answers:
- Bring new hires through a central office, or meet them at the job site on day one, before they scatter.
- Designate a trained authorized representative in each remote location to examine documents and sign Section 2 for the employer; the employer remains responsible for mistakes. See I-9 authorized representative.
- Employers that are enrolled in E-Verify in good standing may examine documents over live video under the DHS alternative procedure; employers that are not enrolled cannot.
That last option is the most common reason a Wyoming employer with no federal contract enrolls voluntarily. It comes with the federal program's conditions: every new hire at an enrolled site gets a case, and no case may be created before the offer is accepted and the I-9 is complete.
Federal contracts in Wyoming
F.E. Warren Air Force Base near Cheyenne, other federal facilities and federally purchased construction are where a Wyoming business usually meets FAR 52.222-54. Contracting officers insert it when a contract is worth more than $150,000, runs at least 120 days and involves domestic work, leaving out contracts limited to off-the-shelf commercial items; subcontracts for services or construction worth more than $3,500 inherit it. The company then has 30 calendar days after award to sign up, and a private firm checks each person it hires, anywhere in the company, while the contract runs, along with current staff assigned to the work. A Casper or Rock Springs subcontractor should read its purchase order: federal dollars passing through a state agency or an energy operator do not by themselves create a federal procurement clause.
A worked example
The company below is invented. A Gillette oil field services company with 200 employees works mostly in Campbell and Converse counties, keeps a crew of 15 in southeastern Montana, and has a small yard in Utah with six employees. It has never enrolled in E-Verify. Its Wyoming work needs only Form I-9. For the Montana crew it chooses Montana's document-copy route and files copies with each I-9. Because the company has 150 or more employees, it reviews Utah's Private Employer Verification Act for its Utah staff. That statute has no direct penalty for not registering but offers a liability shield to employers that do, so the company weighs enrolling its Utah site rather than assuming a fine is at stake.
A Wyoming checklist
- Work only in Wyoming with no federal clause: complete Form I-9, and enroll in E-Verify only if you want to.
- Any workers in Montana: choose and document a LEGAL Act method.
- 150 or more employees with staff in Utah: review Utah's verification act.
- Nebraska public services contracts: enroll and verify.
- Accept any List B license that meets federal rules, whatever its notation.
- Running a staffing firm in the state raises its own licensing questions, covered in staffing agency license requirements in Wyoming.
Questions people ask
Is E-Verify required in Wyoming?
No. As of October 2026 none of the 41 titles of the Wyoming Statutes mentions E-Verify, so there is no requirement for private employers, public employers or public contractors. Bills that would have required employers to verify status died in 2009 and 2011, and a 2025 bill to criminalize employing unauthorized workers was not even considered for introduction.
What did Wyoming House Bill 163 of 2025 propose?
It would have created W.S. 6-7-201, making it a misdemeanor to employ or contract for services with a person unlawfully present or not authorized to work, with a $1,000 fine for a first offense and $5,000 for later offenses, each worker counting separately. It did not mention E-Verify. The House did not consider it for introduction, and it died on February 3, 2025.
Does Wyoming's 2025 driver's license law change what I-9 documents an employer can accept?
No. W.S. 31-7-143 treats certain out-of-state licenses issued to unauthorized aliens as invalid for driving in Wyoming. Form I-9 is governed by federal rules, and USCIS says employers may accept state driver's licenses that carry restrictive notations as List B identity documents. A List B document proves identity only, so the employee still needs a List C document for work authorization.
A Wyoming crew is working in Montana. What applies?
Montana's LEGAL Act, in effect since July 1, 2025, requires employers to keep either an E-Verify confirmation or a completed Form I-9 with copies of the identity and work authorization documents for each new employee, and allows state audits and per-worker fines. It does not require E-Verify, but it does require records that can be produced on three business days' notice.
