Hiring a foreign worker legally in the US in 2026 runs through one of several employer-sponsored visa categories — H-1B (capped at 65,000 plus a 20,000 master’s exemption), H-2B (66,000 statutory, with up to 64,716 supplemental visas this fiscal year), L-1, O-1, TN, E-3, or the EB-2/EB-3 permanent pathways — each with its own Department of Labor and USCIS filing requirements before a worker can legally start. Costs vary by category and currently include an unsettled factor: a proposed $100,000-plus H-1B fee is tied up in federal litigation and, as of this writing, not being collected, alongside standard government filing fees, immigration attorney costs, and for PERM-based sponsorship, documented recruitment expenses.
Get the visa category or the Department of Labor step wrong, and delays run into months, not days. This guide walks through why employers sponsor foreign workers, what you need to know before you start, every major visa category available in 2026, the full step-by-step process, realistic costs, and the compliance obligations — I-9 verification, wage requirements, recordkeeping — that continue long after a worker’s first day. This is general information, not legal advice — immigration rules are reviewed frequently, and a qualified immigration attorney should confirm anything specific to your situation before you file.
Why US Employers Hire Foreign Workers
Most employers sponsor foreign workers for one of a few recurring reasons: a genuine skills gap in a specialized field where qualified domestic candidates are scarce, a seasonal or temporary labor need that domestic hiring can’t reliably fill, an internal transfer of an existing employee from an overseas office, or a specific individual whose expertise is valuable enough to justify the sponsorship process.
None of these reasons change the legal requirements — a genuine skills shortage doesn’t exempt an employer from prevailing wage rules, and a strong candidate doesn’t bypass the need for the correct visa category. What it does affect is which category actually fits. A seasonal hospitality need points toward H-2B; a software engineer with a US job offer points toward H-1B; an existing manager being relocated from a foreign branch points toward L-1. The underlying business reason for hiring and the legal pathway for sponsoring are related but separate questions.
What Employers Must Know Before Hiring a Foreign Worker
Four things determine whether a hire is straightforward or requires full sponsorship: the worker’s existing authorization status, Form I-9 compliance, E-Verify enrollment where applicable, and whether your specific business qualifies to sponsor at all.
1. Employment Authorization
Not every foreign national needs sponsorship. Someone who already holds work authorization independent of your job offer — a green card, certain dependent visa categories with employment authorization, or an existing portable status — can generally be hired like any other employee. Sponsorship becomes necessary specifically when the person’s legal ability to work in the US depends on the job offer itself. Confirming which situation you’re in is the first real decision point, and it changes everything downstream.
2. Form I-9
Every US employer, regardless of whether they sponsor anyone, must complete Form I-9 employment eligibility verification for every employee within three business days of their start date. This applies equally to US citizens and foreign nationals — I-9 compliance isn’t specific to sponsored workers, but it’s worth re-emphasizing here because sponsoring employers sometimes mistakenly treat I-9 as something that’s “handled” by the visa petition itself. It isn’t; it’s a separate, ongoing recordkeeping obligation.
3. E-Verify
E-Verify is a federal electronic system that confirms I-9 information against government records. It’s voluntary for most employers, but mandatory for certain federal contractors and required by law in a number of states. Even where it’s optional, some sponsoring employers use it proactively as part of a broader compliance posture, since it adds a documented verification layer beyond the I-9 form itself.
4. Employer Eligibility
Not every type of entity can sponsor every visa category in the same way. Most employer-sponsored categories require a genuine, documented employer-employee relationship, a legitimate US business presence, and in several categories, evidence of the company’s financial ability to pay the offered wage. Startups and very small businesses aren’t excluded, but they should expect closer scrutiny on these points than an established company with a longer financial track record — a theme covered in more depth later in this guide.
Main Visa Options for Hiring Foreign Workers in the US
Seven categories cover nearly every employer-sponsored hiring situation in 2026, ranging from H-1B’s 65,000-plus-20,000 capped lottery to uncapped options like L-1 and O-1 that carry no annual numerical limit at all.
| Visa | Typical Worker | Annual Cap | Labor Certification | Best For |
|---|---|---|---|---|
| H-1B | Specialty occupation, bachelor’s degree or equivalent | 65,000 regular + 20,000 master’s exemption, lottery-based | LCA (not full PERM) | Tech, engineering, finance, specialized professional roles |
| H-2B | Temporary non-agricultural labor | 66,000 statutory, plus fiscal-year supplemental allocations when authorized | Yes, full labor certification | Hospitality, landscaping, seafood processing, seasonal work |
| H-2A | Temporary or seasonal agricultural labor | No numerical cap | Yes, full labor certification | Farm labor, agricultural production |
| L-1 | Intracompany transferee (manager, executive, or specialized knowledge) | No cap | No | Multinational companies relocating existing staff |
| O-1 | Individual with extraordinary ability or achievement | No cap | No | Highly distinguished individuals in their field |
| TN | Canadian or Mexican citizens in specific professional occupations under USMCA | No cap | No | Cross-border professional hiring |
| E-3 | Australian citizens in specialty occupations | 10,500 annually | LCA (similar to H-1B) | Specialty occupation roles specifically for Australian nationals |
H-1B Visas
Built for specialty occupations generally requiring at least a bachelor’s degree in a specific field. The employer files the petition, starting with a Labor Condition Application attesting to prevailing wage and working conditions. Subject to an annual lottery when registrations exceed the cap, which happens in most years.
H-2B Visas
Covers temporary, non-agricultural labor needs — seasonal demand or a genuine peak-load situation, not an ongoing year-round role. Requires full labor certification, including documented recruitment intended to show qualified US workers aren’t available.
H-2A Visas
The agricultural equivalent of H-2B, for temporary or seasonal farm labor. Unlike H-2B, H-2A has no numerical cap, though it carries its own detailed labor certification and housing/transportation obligations for workers that H-2B doesn’t impose in the same way.
L-1 Visas
For employees being transferred from a qualifying foreign affiliate to a US office of the same company, in a managerial, executive, or specialized-knowledge role. Requires a genuine corporate relationship between the foreign and US entities, and the employee generally must have worked for the foreign entity for a qualifying period before the transfer.
O-1 Visas
For individuals with extraordinary ability or achievement in their field — not limited to any particular industry, and evaluated case by case against an evidentiary standard rather than a fixed cap or lottery.
TN Visas
Available only to Canadian and Mexican citizens, for specific professional occupations listed under the USMCA trade agreement. Generally a faster, less document-heavy process than H-1B for the occupations it covers.
E-3 Visas
A treaty-based category available only to Australian citizens, functioning similarly to H-1B for specialty occupations but with its own separate, smaller annual numerical limit and a generally more streamlined process. E-3 status is also renewable without the same lifetime limits that apply to H-1B.
How to Choose the Right Work Visa for a Foreign Employee
Start with the nature of the role, not the nationality of the candidate. Is this a permanent specialty occupation role requiring a degree? H-1B is usually the starting point, unless the worker’s nationality makes TN or E-3 available, both of which are often faster and less competitive than the H-1B lottery. Is the need genuinely temporary or seasonal? H-2B or H-2A, depending on whether it’s agricultural. Is this an internal transfer of someone already employed by your company abroad? L-1. Does the individual have an unusually distinguished record in their field? O-1 is worth evaluating.
Worker nationality matters in exactly two of these categories — TN is restricted to Canadian and Mexican citizens, and E-3 to Australian citizens — which makes them worth checking first if the candidate happens to hold one of those nationalities, since both routes are typically simpler than H-1B when they’re available.
How to Hire a Foreign Worker in the US: Step-by-Step
Eight steps take a role from “we need to hire internationally” to an employee legally working on US payroll, and the Department of Labor or USCIS can reject a filing over a misstep at any one of them.
- Identify the position and worker. Confirm the role genuinely requires the qualifications you’re specifying, and that the candidate meets them — this documentation matters later, especially for labor-certification-based categories.
- Check visa eligibility. Match the role and worker’s nationality against the category comparison above.
- Determine wage requirements. Most categories require paying at least the prevailing wage for that occupation and geographic area, determined through Department of Labor wage data.
- Prepare the job offer. The offer letter should align precisely with what will be represented in the visa filing — inconsistencies between the offer and the petition are a common source of delay.
- Complete required labor certification. An LCA for H-1B and E-3, or full PERM-style labor certification for H-2B, H-2A, and most green card sponsorship.
- File the immigration petition. Typically Form I-129 for temporary worker categories, or Form I-140 for immigrant (green card) petitions.
- Wait for approval. Processing times vary by category, USCIS workload, and whether premium processing was used — current estimates should be checked directly on USCIS’s website rather than assumed.
- Complete employment authorization and onboarding. Once approved, complete Form I-9 verification and begin standard onboarding, while tracking the visa’s validity period for future renewal planning.
How Much Does It Cost to Sponsor a Foreign Worker?
Six distinct cost categories make up the real price of sponsorship, and government filing fees — the number most employers budget for first — are often the smallest line item once attorney, recruitment, and relocation costs are added in.
- Government filing fees — Base petition fees plus category-specific charges (such as the ACWIA training fee and fraud prevention fee that apply to H-1B), confirmed against USCIS’s current fee schedule rather than an older source, since these are periodically revised.
- Immigration attorney fees — Vary by case complexity; a routine H-1B extension costs considerably less than a PERM case or a response to a USCIS request for evidence.
- Premium processing — An optional additional USCIS fee guaranteeing expedited adjudication within a set number of business days for eligible petition types.
- Recruitment and advertising costs — Required and documented for PERM-based sponsorship, where the Department of Labor expects evidence of a genuine recruitment effort, not just the filing fee itself.
- Relocation expenses — Covered in more detail later in this guide; entirely a matter of company policy rather than a legal requirement.
- Ongoing compliance costs — Tracking renewal deadlines, amending petitions when a worker’s role changes materially, and maintaining required records.
Given how much H-1B-related fees specifically have shifted through litigation over the past year — covered in the next section — this guide deliberately avoids quoting one all-in dollar figure. Confirm current fees directly with USCIS and DOL, and get a specific estimate from an immigration attorney for your actual case.
H-1B Sponsorship for Foreign Workers
H-1B remains the most-used specialty-occupation visa for US employers, but qualification, wage attestation, and the annual 65,000-plus-20,000 lottery each carry their own distinct requirements.
Who Qualifies:
Workers in specialty occupations requiring at least a bachelor’s degree, or its equivalent through education and experience, in a field directly related to the job duties.
Employer Requirements:
The employer must demonstrate a genuine job offer matching the specialty occupation standard, and commit to the wage and working conditions attested to in the Labor Condition Application.
H-1B Registration and Selection:
Employers register candidates electronically during an annual registration period. When registrations exceed the cap — 65,000 regular slots plus 20,000 reserved for US master’s degree holders — USCIS runs a random lottery, and only selected registrants may then file a full petition. Non-selection in a given year is common and doesn’t reflect on the worker’s or employer’s qualifications; it’s simply a function of demand exceeding supply.
Prevailing Wage Requirements:
The Labor Condition Application requires attesting to paying at least the prevailing wage determined by the Department of Labor for that specific occupation and geographic area — not a wage the employer sets independently.
Employer Responsibilities:
Beyond filing, employers must maintain a public access file documenting LCA compliance, notify affected workers appropriately, and in certain circumstances pay return transportation costs if the employment ends before the authorized period expires.
An important 2026 cost caveat: a September 2025 presidential proclamation introduced a $100,000 fee tied to new H-1B petitions for beneficiaries abroad requiring consular processing — not extensions or change-of-status filings. A federal court vacated the implementing guidance in mid-2026, and the fee remains blocked as of this writing following an appellate ruling against the government’s attempt to resume it. A September 2026 proclamation sought to extend the same, still-blocked requirement through September 2027, and a separate DHS-proposed regulatory fee covering a broader set of cap-subject petitions remains in the public comment stage, not yet finalized. A distinct, smaller fee tied to H-1B and L-1 petitions at larger employers did take effect in September 2026 and sits outside this litigation. Treat any specific figure here as a snapshot and confirm current status directly on USCIS.gov.
Green Card Sponsorship for Foreign Employees
Permanent sponsorship runs through a longer sequence than any temporary visa — PERM labor certification, an EB-2 or EB-3 classification, an I-140 petition, and finally adjustment of status or consular processing — often spanning well over a year start to finish.
PERM Labor Certification
The Department of Labor process required for most green card sponsorship, requiring employers to conduct documented recruitment demonstrating that no qualified US worker is available for the role at the prevailing wage.
EB-2
Covers workers with an advanced degree or those who can demonstrate exceptional ability in their field. Generally requires PERM, with narrow exceptions in specific circumstances.
EB-3
A broader category covering skilled workers, professionals with a bachelor’s degree, and an “other workers” subcategory for roles requiring less than two years of training or experience. Also generally requires PERM.
I-140 Petition
Filed with USCIS after PERM certification is approved, formally petitioning for the worker’s immigrant classification.
Adjustment of Status or Consular Processing
Once the I-140 is approved and a visa number is available — which can involve a wait of varying length depending on the worker’s category and country of birth — the worker either adjusts status from within the US or completes consular processing abroad to receive the immigrant visa.
How Small Businesses Can Hire Foreign Workers
Smaller companies absolutely can sponsor foreign workers, but they should expect more scrutiny on a few specific points than a large, established employer would face. Ability-to-pay documentation matters more when a company’s financial history is shorter — USCIS and DOL want confidence that the wage commitment is real and sustainable, which can mean providing more detailed financial records than a Fortune 500 company would need to. A startup with limited operating history sponsoring its first foreign hire should expect to document its financial capacity carefully, and many benefit meaningfully from experienced immigration counsel specifically because smaller companies have less internal precedent to draw on from prior sponsorships.
None of this makes small business sponsorship impractical — it’s a routine part of the process for many startups and small employers — but it does mean budgeting more time for documentation than a larger company might need.
Hiring Foreign Workers Without a US Credit or Immigration Background
Employers sponsoring their first foreign worker, with no prior immigration filing history and no established relationship with an immigration attorney, face a steeper initial learning curve but not a different legal standard. The requirements are the same regardless of whether this is an employer’s first sponsorship or fiftieth. What changes is the practical reality: a first-time sponsoring employer benefits disproportionately from legal guidance, since the cost of a procedural misstep is the same whether or not the company has done this before, and an experienced immigration attorney can meaningfully reduce the risk of easily avoidable errors on a first filing.
Employer Requirements After Hiring a Foreign Worker
Sponsorship obligations don’t end at approval — six distinct compliance duties, from I-9 recordkeeping to termination-related return-transportation costs, continue for as long as the sponsored employee remains on staff.
1. I-9 Compliance:
Ongoing recordkeeping obligation that doesn’t end at the hiring date — I-9 forms must be retained and available for inspection for a required period even after employment ends.
2. Wage Requirements:
Sponsoring employers must continue paying at least the wage committed to in the original filing for the duration of the sponsored status, not just at the point of hire.
3. Worksite Changes:
A material change in work location can, for some visa categories, require filing an amended or new LCA before the employee actually begins working at the new site — this is a frequently missed requirement when companies relocate staff or shift to hybrid arrangements.
4. Visa Extensions
Sponsored status has a defined validity period, and extensions need to be filed with enough lead time to avoid a gap in authorized status — tracking these deadlines proactively, rather than reactively, is essential.
5. Recordkeeping
Beyond I-9s, employers should retain LCA public access files, petition approval notices, and supporting documentation for each sponsored worker, since these may be needed for audits, extensions, or future sponsorship stages.
6. Termination Obligations
Ending a sponsored worker’s employment before their authorized status period expires can trigger specific obligations, including, for H-1B specifically, responsibility for return transportation costs in some circumstances — this is worth understanding before a termination decision, not after.
How Long Does It Take to Hire a Foreign Worker in the US?
There’s no single answer, because timeline depends heavily on the category. H-1B is constrained first by the annual registration and lottery timing, then by standard or premium processing once a petition is filed. PERM-based green card sponsorship typically takes considerably longer overall, since it involves a documented recruitment period before the labor certification can even be filed, followed by the I-140 petition and, depending on the worker’s country of birth, a potentially significant wait for visa number availability. L-1 and O-1 generally move faster than the PERM-based categories, since they don’t require labor certification at all. Current USCIS and DOL processing time estimates, checked directly rather than assumed from a general guide, are the only reliable way to plan around a specific filing.
Common Mistakes Employers Make When Hiring Foreign Workers
Seven errors account for most of the preventable delays, denials, and penalties employers encounter during sponsorship — and nearly all of them are avoidable with earlier attention to deadlines and documentation.
- Hiring before work authorization — allowing someone to begin work before their status or authorization is actually in place
- Using the wrong visa category — matching a worker to a category based on a general sense of their qualifications rather than the specific legal requirements of that category
- Paying the wrong wage — offering less than the prevailing wage requirement, even unintentionally
- Missing filing deadlines — particularly extension deadlines, which can leave a worker without valid status
- Incorrect I-9 procedures — errors in timing or documentation that create compliance exposure independent of the visa itself
- Failing to update petitions after major changes — a worksite move, role change, or salary adjustment that should have triggered an amended filing
- Treating immigration compliance as the employee’s responsibility — the employer, not the worker, bears most of the legal and financial obligations tied to sponsorship
Immigration Lawyers and Professional Help for Employers
Whether you need an attorney depends on complexity. A single, straightforward H-1B extension is something some employers’ internal HR teams manage confidently, particularly with prior experience. PERM labor certification, by contrast, involves enough procedural detail — specific recruitment steps, strict timing windows, and documentation standards — that most employers engage immigration counsel for it, since errors can restart the process or delay it by months.
A business immigration attorney typically helps with selecting the correct category, preparing and reviewing filings, responding to requests for evidence, and advising on company-wide policy if sponsorship happens regularly rather than as a one-off. This is distinct from recruitment agencies, which source candidates but don’t provide legal representation — the two roles complement each other but shouldn’t be confused.
How to Build an International Hiring Process
Employers who sponsor regularly benefit from treating immigration compliance as a standing internal process rather than a one-off project each time a need arises. That typically means designating a clear internal owner for sponsorship cases, maintaining a tracking system for visa expiration and extension deadlines across all sponsored employees, establishing a relationship with immigration counsel before an urgent need arises rather than during one, and building sponsorship timelines into hiring plans early enough to account for category-specific constraints like the H-1B lottery or PERM’s recruitment period.
This matters most for companies that expect to sponsor more than occasionally — a single one-time hire can be managed reactively, but a company building an internationally sourced team benefits from a repeatable, documented process rather than reinventing it with each new hire.
Relocation and Benefits for Foreign Employees
None of what follows is legally mandated, but relocation packages, health insurance parity, temporary housing, and travel coverage are what competitive employers use to win sponsored candidates away from other offers.
I, Relocation Packages
Covering flights, moving costs, and sometimes a lump-sum allowance — entirely a matter of company policy, not a legal requirement, though competitive for specialized roles where employers want to reduce friction for the candidate.
II, Health Insurance
Sponsored employees are generally offered the same health benefits as comparable domestic employees, both as standard practice and, for H-1B specifically, because the Labor Condition Application’s working-conditions attestation can raise questions if sponsored workers receive meaningfully different benefits than their peers.
III, Temporary Housing
Some employers provide short-term housing support while a newly arrived employee secures permanent accommodation — a practical, policy-driven benefit rather than a requirement.
IV, Travel Expenses
Initial relocation travel is sometimes covered by the employer; return travel obligations can also apply in specific termination scenarios for certain visa categories, as noted earlier.
V, Employee Onboarding
Beyond standard onboarding, sponsored employees often benefit from additional orientation covering practical settlement topics — banking, housing, and local logistics — which, while not legally required, can meaningfully improve retention for employees who’ve relocated internationally for the role.
Government Resources Employers Should Check Before Sponsoring a Worker
Four federal sources hold the current fees, caps, and processing data this guide can’t substitute for, since all four are reviewed and updated more frequently than any general article can track.
- USCIS.gov — Current forms, filing fees, processing times, and cap/lottery status for each visa category
- US Department of Labor — Prevailing wage data, LCA filing, and PERM labor certification guidance
- US Department of State — Consular processing procedures and visa bulletin updates for immigrant categories
- E-Verify.gov — Enrollment and compliance information for employers using the system
Checking these directly, rather than relying on a general guide for specific current figures, is the only reliable way to confirm fees, caps, and processing times that change periodically — as this guide’s H-1B fee discussion illustrates.
Frequently Asked Questions
Can a US company hire a foreign worker?
Yes. Depending on the worker’s existing status, this may mean standard hiring with I-9 verification, or it may require employer sponsorship through a specific visa category.
How does a company sponsor a foreign worker?
By selecting the appropriate visa category, completing any required Department of Labor step, filing a petition with USCIS, and the worker then completing consular processing or adjustment of status.
How much does it cost to sponsor a foreign worker?
Costs vary significantly by category and include government fees, attorney fees, and for PERM-based sponsorship, recruitment costs — confirm current figures directly with USCIS and DOL, particularly for H-1B given ongoing fee litigation.
What visa does a small business use to hire internationally?
The same categories available to any employer — H-1B, L-1, O-1, and others — though small businesses should expect closer scrutiny of their financial ability to pay the offered wage.
Does hiring a foreign worker guarantee visa approval?
No. Eligibility, documentation quality, and category-specific requirements all factor into the outcome, and no employer or guide can guarantee approval.
What is PERM labor certification?
A Department of Labor process requiring documented recruitment to demonstrate no qualified US worker is available for the role, generally required before most green card sponsorship categories.
How long does employer sponsorship typically take?
It varies enormously by category — H-1B is shaped by the lottery and processing time, PERM-based green card sponsorship generally takes considerably longer due to the recruitment period and potential visa number wait.
Do employers need an immigration lawyer?
Not always for simple, familiar filings, but PERM’s complexity and the stakes of an incorrect H-1B filing make professional help genuinely valuable for most employers beyond routine cases.
What happens if an employer makes a mistake in the sponsorship process?
Consequences range from processing delays to petition denial, depending on the error’s nature and severity — which is why review by experienced counsel reduces risk considerably on anything beyond the most routine filing.
Can employers sponsor workers for permanent residence?
Yes, generally through EB-2 or EB-3, both of which typically require PERM labor certification before an immigrant petition can be filed.
Conclusion: Hiring Foreign Workers Legally in the US
Hiring foreign workers legally in the US in 2026 means matching the right visa category to the actual role, meeting Department of Labor requirements where they apply, and treating sponsorship as an ongoing compliance relationship rather than a single filing event. The available categories — H-1B, H-2B, H-2A, L-1, O-1, TN, E-3, and the EB-2/EB-3 permanent pathways — cover a wide range of hiring situations, but eligibility, cost, and timeline differ substantially between them, and the H-1B fee picture specifically remains genuinely unsettled while litigation continues.
Confirm current fees, caps, and processing requirements directly with USCIS and the Department of Labor before filing, and bring in an immigration attorney for anything beyond the most straightforward sponsorship case — the cost of getting a filing wrong is almost always higher than the cost of getting help to get it right.
