H-1B Sponsorship for Employers: Requirements, Process & Costs in 2026

H-1B sponsorship is the formal process a U.S. employer uses to hire a foreign national worker in a specialty occupation — a role that requires at least a bachelor's degree (or its equivalent) in a specific field. The H-1B is the most heavily used temporary work visa in the United States, with technology, finance, healthcare, engineering, and architecture employers relying on it to fill roles where domestic talent is in short supply. The annual statutory cap means that sponsorship includes both a Labor Condition Application (LCA) at the Department of Labor and an I-129 petition at USCIS, and every year employers must navigate a programmatic lottery, prevailing-wage compliance, and strict filing fees — and increasingly, plan for the long-term green-card retainment of the same worker.

This guide collects the 2026 employer playbook in one place. It walks through the LCA step-by-step, the FY calendar of registration, lottery, and I-129 filing, the complete fee schedule with company-size adjustments, and the pathway from sponsored worker to permanent resident. If you are budgeting for one hire or twenty, the tables and timelines below will let you plan with confidence.

What is H-1B sponsorship and when do you need it

H-1B is a nonimmigrant (temporary) visa classification that lets a U.S. employer bring a foreign national into the country to perform services in a specialty occupation. Sponsorship is what ties the visa to the sponsoring employer: an H-1B worker cannot legally work for a U.S. company without an approved H-1B petition filed by that specific employer. The worker is tied to the petition, the worksite, the wage on the certified LCA, and the job duties described in the filing.

The Department of Homeland Security defines a specialty occupation as a position that meets at least one of the following criteria:

• Theory and practical application of a body of highly specialized knowledge. Examples include software engineering, data science, financial analysis, architecture, medicine, and biotechnology research.
• Bachelor's or higher degree (or equivalent) is normally the minimum entry requirement. The occupation is one where the industry-wide standard for entry is at least a U.S. bachelor's degree (or its foreign equivalent) in a directly related specialty.
• The degree is common to similar positions in the industry. For most H-1B roles (engineer, analyst, scientist), this is straightforwardly true.
• The position is so specialized or complex that only a person with a degree can perform the duties. This is the catch-all criterion and is where most Requests for Evidence (RFEs) are issued.

When H-1B is the right choice vs. an alternative

H-1B is not always the optimal visa for a given hire. The alternatives are not cap-subject (they are not lottery-locked), and can be cheaper and faster to file. The most common alternatives are:

• O-1A Extraordinary Ability — for individuals with sustained national or international acclaim. No annual cap, no lottery, fast adjudication, premium processing eligible. Worth considering for any candidate who has publications, awards, high salary, judging roles, or original contributions.
• L-1 Intracompany Transfer — for workers who have been employed by a qualifying foreign affiliate of the U.S. employer for at least one continuous year in the preceding three years. No cap, no lottery. L-1A managers and executives can also transition to EB-1C green card without a PERM labor certification.
• TN (USMCA Professionals) — for Canadian and Mexican citizens in designated professional occupations. Renewable indefinitely in one-year or three-year increments, fast, no lottery.
• E-3 Australia — similar in structure to H-1B but limited to Australian nationals in specialty occupations. Smaller applicant pool means the practical lottery pressure is lower.
• Cap-exempt H-1B at an institution of higher education, a nonprofit research organization, or a government research organization — these employers can file H-1B petitions at any time with no lottery. If you have a hosting agreement or research collaboration with such an organization, the cap-exempt route is often the fastest path.

Two fee tiers: under 50 vs. 50+ U.S. employees

If your company has 50 or more full-time equivalent U.S. employees and more than 50% of those employees are in H-1B or L status, you pay an additional $4,000 fee on each new H-1B petition under Public Law 114-65. This is the fee rule most often misquoted online — it depends on both the headcount test and the proportion test, and the proportion test is reviewed against your current workforce at filing, not at registration. Most mid-size and large technology, consulting, and staffing companies hit both conditions. Smaller companies and most startups do not.

Likewise, the ACWIA training fee has two tiers: $750 for employers with 25 or fewer full-time U.S. employees; $1,500 for those with 26 or more. Both are smaller-company-friendly classifications — confirming that small employers do pay proportionally less, not more, of the regulatory fee load.

The fiscal-year clock

H-1B start dates follow the federal fiscal year, which begins October 1. For cap-subject cases, the lottery is run in March/April of the preceding calendar year, and the earliest employment start date is October 1 of the fiscal year named in the registration. A "FY2027 H-1B" filed in March 2026 starts work no earlier than October 1, 2026. The lottery window and start-date rule are fixed — there is no expedited or fast-track way around them for cap-subject petitions. Cap-exempt H-1Bs, extensions, and amendments can be filed at any time and start as soon as approved.

Labor Condition Application (LCA) — step by step

The Labor Condition Application (LCA, Form ETA-9035) is the prerequisite to filing any H-1B petition. It is filed with — and certified by — the Department of Labor (DOL), not USCIS. Until an LCA is certified, the employer has no standing to file an I-129, and the LCA's wage, location, and worksite data become binding for the entire H-1B period. Mistakes at this phase propagate through every downstream filing.

Step 1 — Determine the prevailing wage

Every LCA must state the wage the employer will pay the H-1B worker. By law, that wage must be at least the prevailing wage for the SOC (Standard Occupational Classification) code and worksite location, as published by the DOL's Office of Foreign Labor Certification (OFLC). Prevailing wages come from one of three sources:

• OES (Occupational Employment Statistics) wage survey — the default source, updated annually. Covers the largest set of occupations and geographies.
• FLAG (Foreign Labor Application Gateway) prevailing wage — used when OES does not have a wage level for a specific occupation or area.
• Employer-conducted survey — only used when neither OES nor a DOL-published wage is available; the survey must meet strict DOL statistical methodology.

The DOL classifies prevailing wages into four levels (I entry, II qualified, III experienced, IV fully competent) based on the complexity and supervision requirements of the job. Wage Level I is the lowest; Level IV is the highest. An employer that misqualifies a senior role as Level I invites the most common audit trigger in the LCA process. Time the wage determination carefully — DOL processing for non-OES requests can stretch several months in some cases.

Step 2 — File the LCA via iCERT / FLAG

The LCA is filed electronically through the DOL's FLAG (Foreign Labor Application Gateway, successor to iCERT) system at flag.dol.gov. The submission includes:

• Employer name, EIN, and worksite address (one LCA per worksite)
• SOC code, occupational title, and wage level
• Actual wage paid to similarly employed U.S. workers
• Prevailing wage source and exact dollar figure
• Begin date and end date of the employment period
• Number of H-1B workers on the LCA
• Part-time vs. full-time designation

DOL certification typically takes 7 business days, although processing can take longer during peak season (January–March). Certification triggers the notice-posting obligation and starts the public access file clock.

Step 3 — Post the LCA at the worksite for 10 business days

Before the LCA is filed the employer must give notice of the H-1B employment to existing workers at the worksite. Notice must be provided in one of two ways:

• Hard-copy posting at two conspicuous locations at the worksite for 10 consecutive business days; or
• Electronic notification to all employees at the worksite through the employer's intranet, email, or a similar internal channel — provided that employees can access it during the notice period.

The notice must include the occupational classification, the wage rate, the worksite location, and a statement that complaints may be filed with the DOL Wage and Hour Division. Failure to post — or posting with incorrect content — is one of the most common audit findings and can carry back-wage liability even when the prevailing wage itself was correct.

Step 4 — Maintain the public access file

Within one business day of a public request — and on demand from any member of the public — the employer must produce a public access file (PAF) for the H-1B worker. The PAF must contain:

• A copy of the certified LCA
• A statement of the actual wage paid to the H-1B worker
• A summary of benefits offered to U.S. workers and H-1B workers
• Documentation supporting the prevailing wage determination (the source survey, the wage level rationale)
• Evidence of notice posting (the dated posting or the email distribution list)

The PAF must be retained for one year beyond the LCA's validity end date. Missing or incomplete PAFs are the second most common audit finding and are treated as violations independent of any wage or posting problem.

Step 5 — Confirm DOL certification

Once the LCA is certified, the employer must keep a copy of the certified LCA on file, retain proof of posting, and ensure the public access file is up to date. Only then can the I-129 H-1B petition be filed with USCIS, and the LCA must remain valid for the entire H-1B period. If the LCA's dates do not span the full requested H-1B validity, USCIS will issue a Request for Evidence or deny the petition.

H-1B registration and petition process (FY calendar)

The H-1B cap-subject process is a calendar-driven sequence, and almost every miss attributed to "USCIS delays" is actually a calendar deadline that the employer allowed to slip. The following table shows the deadlines that an FY2027 cap-subject petition — registration in March 2026, start date October 1, 2026 — requires:

Two practical notes on the calendar. First, the registration window is short — usually 14 days in mid-March — and USCIS has on multiple occasions modified the dates on short notice. Treat any "expected" window as guidance, not a guarantee, and be ready to register the same day the window opens. Second, the 90-day filing window after lottery selection is unforgiving: if the I-129 packet is not received by USCIS within 90 days, the selection is forfeited and the beneficiary must register again in the following March. This window cannot be extended.

Change of status vs. consular processing

If the beneficiary is already in the U.S. in another nonimmigrant status (typically F-1, OPT, L-1, or TN), you can request a change of status (COS) inside the I-129. COS lets the beneficiary remain in the U.S. throughout adjudication and start working in H-1B status on October 1 — even if approved later — as long as the underlying stay has not expired. For beneficiaries outside the U.S., the I-129 must be approved first; the beneficiary then attends a consular visa interview at a U.S. embassy or consulate abroad to receive the H-1B visa stamp. Consular processing adds weeks to months on top of USCIS adjudication and is highly variable by country. India and China have historically had the longest consular wait times.

Employer cost table: filing fees, attorney fees, government fees

H-1B sponsorship carries mandatory government filing fees that — by 20 CFR 655.731 — the employer cannot lawfully shift to the employee. The exception is optional premium processing, which the employee may voluntarily agree to pay. Below is the consolidated schedule of 2026 H-1B costs the employer should plan for:

For a personalized breakdown tied to your specific company size and processing choices, see our live H-1B fee calculator or the full employer cost calculator. Note that additional government fees apply on H-1B extensions (the I-129 base + ACWIA + Fraud Prevention fees recur on each extension) and on amendments for worksite or wage-level changes filed mid-petition. Green-card sponsorship triggers a separate fee structure — under the PERM labor certification process the employer pays all costs and may not shift them to the employee.

How to retain sponsored workers long-term (green card pathway)

The H-1B is a temporary nonimmigrant visa. An H-1B worker is admitted for an initial period of up to three years, extendable once for a second three-year term — for a maximum six-year stay as an H-1B. After six years (or before, if the worker has an approved I-140 immigrant petition and is waiting for a priority date), the worker must either depart the U.S., obtain a different nonimmigrant status, or adjust status to permanent residence. Most employers who invest in H-1B sponsorship of a critical employee do not stop at the temporary period — they begin green-card sponsorship in parallel so the same worker can transition to permanent residence without ever leaving the company.

Step 1 — PERM labor certification (the binding step)

The Program Electronic Review Management (PERM) process is how you, the employer, demonstrate to the DOL that there are no qualified U.S. workers available for the same role at the prevailing wage. PERM proceeds in three sub-stages:

• Prevailing Wage Determination (PWD) — a request to the DOL National Prevailing Wage Center for the wage you must offer in the PERM recruitment
• Recruitment — required ads on the company website, two Sunday newspaper ads, a job bank posting, and internal notices; the recruitment window runs 30+ days with strict documentation rules
• ETA 9089 filing — within the validity of the PWD, file the permanent labor certification application with DOL for review

PERM processing times in 2026 run roughly 6–18 months for audited cases and a few months for un-audited cases. Failed recruitment — including too narrow a job description, not posting long enough, or offering a wage that fails the recruitment wage test — is the most common reason for PERM denials. Always work with experienced immigration counsel on the recruitment step.

Step 2 — I-140 immigrant worker petition

Once the PERM is approved, the employer files Form I-140 (Immigrant Petition for Alien Worker) with USCIS, classifying the worker under one of the employment-based preference categories:

• EB-1 — priority workers (extraordinary ability, outstanding professors/researchers, multinational executives). PERM is generally not required for EB-1.
• EB-2 — professionals with advanced degrees or exceptional ability. The most common PERM → I-140 path for H-1B workers in tech, finance, and academia. EB-2 NIW (National Interest Waiver) is a self-petitioned variant that can bypass PERM.
• EB-3 — skilled workers, professionals, and other workers. Used when the role does not require an advanced degree.

The I-140 establishes the worker's priority date — the date on which the PERM was filed (or the I-140 itself, if PERM was bypassed). That priority date determines the worker's place in the green-card queue.

Step 3 — Waiting for the priority date

The Department of State publishes the monthly Visa Bulletin, which lists the priority dates that are currently being processed for each preference category and chargeability area. Workers must wait until their priority date becomes "current" before they can file Form I-485 (Application to Adjust Status) or proceed with consular processing. Per the May 2026 Visa Bulletin, EB-2 India and EB-3 China and India retrogress heavily — multi-year waits are common. EB-2 Rest of World and most other categories are typically current within a year or two.

Step 4 — AC21 portability mid-process

Under the American Competitiveness in the 21st Century Act (AC21), a worker whose I-485 has been pending for 180 days (or whose I-140 has been approved) can change employers without losing their place in the green-card queue. This is the rule that protects retention: an H-1B worker being sponsored for a green card is not locked in to the sponsoring employer, and the new employer's I-140 can take over the original priority date. Workers who have built considerable tenure with one employer often use AC21 as a negotiation tool — it is part of the long-term retention strategy you should explain to senior H-1B hires.
