To verify a subcontractor’s work authorization lawfully in the United States, first determine which business actually employs the worker. A general contractor does not automatically become the employer just because the work takes place on its site, and a contract label alone may not settle the question. If the subcontractor employs the worker, do not demand or collect particular immigration documents simply to satisfy a site check; if your business employs the worker, follow the Form I-9 process consistently. Unclear or unusual arrangements call for tailored legal advice before you collect documents or make a work-authorization decision.
The practical sequence is straightforward: identify the employer, distinguish an employment-eligibility check from a site or contract requirement, and then use the process that actually applies. Form I-9 is for a business’s own employees; E-Verify is a separate electronic system used by participating employers. Neither a software vendor nor a subcontract clause automatically resolves an uncertain relationship or transfers the employer’s responsibility.

Who is responsible for verifying a subcontractor’s workers?
The business that hires a person as an employee for work in the United States is generally the business responsible for completing and retaining that person’s Form I-9. The first step is therefore to identify the actual employer—not to start by asking a worker to show a passport, green card, or work permit. Federal guidance says employers must complete and retain Form I-9 for each person they hire for employment in the United States after November 6, 1986.
On a construction project, a general contractor, subcontractor, staffing company, and other businesses may each have different roles. The fact that someone works at a general contractor’s site does not by itself establish which company hired the person. Review how the arrangement works in practice, including who directs and employs the worker; do not rely on a contract label alone. The available federal guidance does not provide a complete test for joint-employer status or resolve responsibility for every subcontracting chain.

USCIS materials describe an independent-contractor exception involving whether the hiring entity sets the person’s work hours or provides tools. That short description is not a complete legal test for every construction arrangement. If your company controls aspects of the work, the contract and day-to-day facts are complex, or it is not clear who hired the person, get advice about the specific relationship before deciding that your company must—or does not have to—complete an I-9. See the USCIS Form I-9 overview and DOL I-9 Central.
Think of the first question as “Who hired this worker?” rather than “Who owns the jobsite?” Ask which business brought the person on as an employee and consider the real arrangement, including the parties’ roles in directing and employing the worker. The sources do not supply a one-size-fits-all checklist that settles every question about control or joint employment, so a short answer from a project manager or a label in a subcontract may not be enough.

- Your business hired the person as an employee: use the current I-9 process for your own hire, consistently and without discrimination.
- A subcontractor hired the person as its employee: do not assume that site presence makes the worker your employee or authorizes you to perform a separate document check. Address any legitimate subcontract-management concern through the appropriate business channel and review any distinct applicable requirement.
- The person is described as an independent contractor, or more than one entity appears to employ or direct the worker: do not treat the label or one fact as conclusive. Get advice on the actual arrangement before deciding who has an I-9 responsibility.
This sequence is a way to organize the issue, not a determination of legal status. A particular federal contract, state or local rule, industry requirement, or unusual control arrangement may add questions that the general federal guidance summarized here does not answer.
What should a general contractor do before asking for documents?
Begin with the employer relationship and the purpose of the request. If your company is not the worker’s employer, a site-access or subcontract-management concern does not automatically authorize you to conduct an employee’s I-9 process. Avoid collecting copies of immigration or identity documents from a subcontractor’s workers unless counsel has confirmed a lawful, applicable basis and process.
- Identify the employing business. Confirm which entity hired the worker and assess the actual arrangement, not just the subcontract’s wording. If the answer is uncertain, pause the document request and ask counsel to review the facts.
- Separate employment verification from project controls. A client may have site, safety, credentialing, or contract requirements, but those are not automatically a reason to ask a worker for a particular immigration document. Determine what the requirement actually calls for and whether it applies to your company or the subcontractor.
- If your company employs the worker, use the official I-9 process. Obtain the current Form I-9 and instructions from USCIS and apply the same process to employees without regard to citizenship, immigration status, or national origin.
- Let the employee choose acceptable documents. Do not tell the employee to present a specific document or extra documents when they can present acceptable documents under the I-9 rules. Do not reject documents that reasonably appear genuine and relate to the employee because of citizenship, immigration status, or national origin.
- Keep E-Verify separate. If your company participates, treat E-Verify as a separate step after completing Form I-9, and follow its current rules consistently. It does not replace Form I-9.
- Escalate questions about special rules. A federal contract, state or local requirement, industry rule, or unusual control arrangement may raise separate issues. The federal sources cited here do not determine those requirements for a particular project; have counsel review them.
For a subcontractor’s own employees, a cautious compliance approach is to address the issue with the subcontracting business rather than direct workers to prove their immigration status to the general contractor. Do not assume that a certification, roster, or document-copy requirement is legally required or sufficient: the appropriate contract language and any additional verification obligation depend on the facts and applicable rules.
Before putting a procedure in place, clarify what you are trying to accomplish. A request intended to confirm that a subcontractor is meeting its obligations is not the same thing as asking a worker to establish eligibility for employment with your company. Likewise, a site badge or safety credential is not automatically an I-9 document. Keep the purpose narrow, identify who is responsible for each step, and avoid having supervisors invent document demands on the spot.
If a project owner or prime contract asks for a particular verification step, do not assume that the request itself determines who must complete Form I-9 or what documents a worker must show. Ask whether the requirement is about employment eligibility, access, or another contract obligation; identify the party it applies to; and have counsel review the language if its effect is unclear. The cited federal guidance does not establish a universal subcontract clause, certification, roster, or document-copy process for every project.

What does Form I-9 require—and what should you avoid?
Form I-9 is the federal employment eligibility verification process for a business’s own employees. It is not a general construction-site credential check, and it is not a license to demand whichever document seems most reassuring to a supervisor.
Once the employer relationship is clear, use the current official form and instructions, complete the process consistently, and let the employee choose from the acceptable document options. USCIS’s employee information sheet explains the employee’s choices and states: “Employees do NOT need to prove their citizenship, immigration status, or national origin when establishing their employment authorization for Form I-9 or E-Verify.” Read the USCIS employee information sheet before establishing a procedure for supervisors or project staff.
The document-choice rule matters in day-to-day interactions. An employee may offer documents from the acceptable options; the employer should not steer the person toward a preferred item or add requirements based on assumptions about the employee. The right response to “Which documents do I need to show my employer?” is to point the employee to the official instructions and let the employee choose among the acceptable options, rather than naming a preferred document.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Fix the driver behind crashes, sound loss and screen glitches3Clear out junk files and repair common Windows errors- Do not demand a green card, passport, or work permit by name. An employee may choose other acceptable documents. Asking for a particular item based on an assumption about the person’s citizenship or immigration status risks unlawful discrimination.
- Do not request extra documents as a substitute for following the process. A request for more paperwork because a worker looks or sounds foreign, or because of national origin, is not a lawful shortcut.
- Do not reject a document for an improper reason. Federal guidance cautions against rejecting documents that reasonably appear genuine and relate to the employee based on citizenship, immigration status, or national origin.
- Do not treat a subcontractor’s workers differently based on assumptions. If your business is the employer, apply the same verification process consistently. If it is not, do not turn a project check into a separate citizenship inquiry.
- Do not make the employee prove citizenship or immigration status as an extra step. The I-9 process concerns employment eligibility; it does not require a worker to prove citizenship, immigration status, or national origin to establish authorization through the process.
The DOJ overview of Form I-9 and E-Verify describes the federal process and anti-discrimination concerns. If an employee asks which documents to show or whether an employer can require a specific one, refer them to USCIS’s information sheet rather than improvising a document list.
Consistency is an important safeguard. A supervisor should not ask one worker for a particular document because of a name, accent, appearance, or perceived citizenship, while accepting another worker’s selection of acceptable documents. If a worker asks, “Can my employer require a specific document?”, the answer for the I-9 process is that the employee chooses from the acceptable options; the employer should not demand a particular document or extra papers based on citizenship, immigration status, or national origin.
Keep site personnel from turning a routine access conversation into an improvised eligibility inquiry. Give staff a clear escalation route for questions and use official instructions when your business is completing an I-9. If the concern is about a subcontractor’s performance or a contract assurance, direct it through the business relationship and obtain advice on the appropriate process instead of asking the worker to hand over documents.
Is E-Verify the same as Form I-9?
No. Form I-9 is the employment eligibility verification process; E-Verify is an electronic comparison system used by participating employers. E-Verify does not replace Form I-9, and its use brings separate program rules that employers must follow.

If your company participates in E-Verify, follow current program requirements and create cases only in the proper context for your own employees. DOJ’s guidance says participating employers must use the program consistently and without discrimination. Do not use E-Verify as a reason to demand particular documents, or assume that a site-wide subcontractor screening is automatically permitted. Confirm the rules that apply to your participation and the specific worker relationship using the DOJ’s Form I-9 and E-Verify guidance.
The distinction is important when deciding which process is involved. First, establish whether your company hired the worker as an employee and complete Form I-9 where required. E-Verify is an additional electronic comparison step for participating employers, not a substitute form and not a shortcut for figuring out which business employed someone. It does not turn every person at a project site into an employee of the general contractor.
Do not assume that using the system permits a broader document request or an inconsistent process. A participating employer still needs to follow the applicable program rules and nondiscrimination requirements. If you are unsure whether the program applies to a particular worker or whether a project-specific obligation changes the steps, check current official guidance and get advice rather than relying on a site-wide practice developed without review.
Can I-9 software or a subcontract clause transfer responsibility?
No. Commercial or proprietary I-9 software does not, by itself, transfer an employer’s legal responsibility or guarantee compliance. A subcontract clause or software workflow cannot resolve an unclear employer relationship or make discriminatory document demands lawful.
If your company uses software, ensure its process supports the official I-9 rules and does not steer employees toward particular documents or prompt staff to request extra documents improperly. DOJ and ICE’s April 2025 fact sheet on I-9 software and compliance discusses the risks of using commercial or proprietary programs. For a construction contract, have counsel review language that addresses verification, access, record handling, or subcontractor assurances; the sources cited here do not establish a universally sufficient clause.
Software can be a workflow tool, but choosing a vendor is not the same as determining which entity has the duty or ensuring that staff use the process lawfully. A program’s prompts and document-handling features should be reviewed against the official instructions. If a tool recommends a specific document, encourages extra demands, or creates an assumption that an employer can outsource responsibility, do not treat the software output as a legal answer.
There is no special physical tool or commercial product identified as necessary for this process. Employers can obtain official forms and instructions from government sources. A commercial service may be something a business elects to use, but DOJ specifically cautions that using commercial I-9 software does not guarantee compliance. The important decisions remain who employed the person, what requirements apply, and whether the process is consistently and lawfully administered.

Similarly, a subcontract does not settle every question simply by assigning responsibility in its wording. Contract terms may be relevant to project obligations, but they do not by themselves determine the actual employment relationship or establish that any requested worker documents are appropriate. If the contract calls for verification-related assurances, record handling, or access controls, review the exact obligation and its legal basis with counsel before implementing it.

Seek advice before taking action when the employing entity is unclear, the contract and actual work arrangement do not align, or a project-specific rule appears to add a verification duty. Tailored review is also appropriate where a federal contract, state or local law, industry requirement, or control arrangement may change the analysis. The federal sources in this article do not decide responsibility in every subcontracting, joint-employer, or contract-specific situation.
It is especially prudent to pause before requesting documents when more than one business appears to direct or employ the person, the subcontract labels someone an independent contractor but the work arrangement is disputed, or a project owner is asking for a form of proof that is not part of the ordinary I-9 process. Those facts do not themselves resolve the legal answer; they are reasons to have the actual contract and working arrangement reviewed before deciding who should act.
Legal review may also help separate requirements that arise from different sources. The relevant issue could be a federal employment-verification rule, a contract term, or a state or local or industry-specific requirement. The general federal sources summarized here do not decide the last category for a particular reader’s project. Do not treat a broad statement about Form I-9 as a conclusion that no other applicable rule exists—or that a contract demand is automatically valid.
If the question is about discrimination in the employment verification process, DOJ’s Immigrant and Employee Rights Section (IER) provides employer guidance and a hotline. Its frequently asked questions explain where employers can direct questions. For a specific project or worker, obtain legal advice based on the actual facts rather than treating general guidance as a determination about your company.

Which official sources should I use?
Use current government forms and guidance rather than an old checklist or an informal site procedure. The DOL’s I-9 Central page points employers to federal I-9 information; USCIS provides the form, instructions, employee information sheet, and overview; DOJ explains anti-discrimination obligations and E-Verify. Check current program and form requirements when you establish or update a process.
Useful starting points include the USCIS employee information sheet dated April 12, 2023, which addresses employee document choices; the USCIS Form I-9 overview, which describes exceptions including the limited independent-contractor description; and DOJ’s April 2025 fact sheet about software and compliance. Check that you are using current forms and instructions, rather than relying on an older checklist or an informal practice copied from another project.

There is no need to buy a physical product to obtain the government form or its instructions. A business that chooses commercial software should not treat the purchase as a compliance guarantee or transfer of responsibility. For fact-specific questions about a subcontracting chain or added project requirements, official general guidance may be a useful starting point, but it cannot replace a review of the actual arrangement.
Frequently Asked Questions
Can a subcontractor’s employee refuse to show me immigration documents at the jobsite?
A worker’s refusal to show documents to a general contractor does not, by itself, establish that the worker lacks authorization; the general contractor may not be the employing entity responsible for Form I-9. Determine who hired the person and whether a separate, applicable site or contract rule exists before treating the refusal as a compliance violation.
Can I ask a subcontractor to confirm it completed I-9s for its employees?
The federal guidance here does not prescribe a universal certification or document-request process for general contractors. If you want an assurance in a subcontract, have counsel review the wording and how it will be used; do not assume that requesting employee document copies is necessary or appropriate.
What if an employee offers a specific document without being asked?
Use the official I-9 procedure and do not use the offer as a reason to demand additional documents. Employees choose from acceptable documents, and employers should not steer them toward a particular document based on citizenship, immigration status, or national origin.
Where can an employer ask about possible discrimination in Form I-9 checks?
The DOJ Immigrant and Employee Rights Section provides employer information and a hotline for anti-discrimination questions. Its IER FAQ page is a starting point for finding the relevant guidance.
Which documents do I need to show my employer for Form I-9?
Employees may choose from the acceptable document options under the I-9 process. Consult the current official instructions and the USCIS employee information sheet; the employer should not direct you to a particular document based on citizenship, immigration status, or national origin.
The Bottom Line
Bottom line: First identify which business actually employs the worker. If your business hired the person as an employee, complete the current Form I-9 process consistently and let the employee choose acceptable documents; if a subcontractor employs the person, do not turn a site check into an ad hoc immigration-document demand. E-Verify is a separate program, commercial software does not guarantee compliance, and unclear control or contract questions deserve tailored legal review.
