The H-1B Visa, Explained

Part of our Company Visas practice

The H-1B is the main US work visa for specialty occupations, meaning roles that normally require at least a bachelor’s degree in a directly related field. It matters because it can open a long-term US career path, but only if the employer, the role, and the filing strategy all fit a heavily regulated category.

The category is also more dynamic than many guides suggest. USCIS currently treats cap-subject H-1B cases through an electronic registration system with a required fee and, if selection is needed, a process tied to wage-level information in the registration record, as described on the current USCIS H-1B electronic registration page. For European employers and professionals, understanding those current mechanics is the difference between a realistic plan and a filing that fails before the full petition is even reviewed.

What the H-1B Is (and Is Not)

The H-1B is a strictly employer-driven visa for specialty-occupation work, not a flexible self-petition that the worker can run independently.

The H-1B is an employer-sponsored, nonimmigrant work visa for specialty occupations. USCIS defines a specialty occupation as work requiring the theoretical and practical application of highly specialized knowledge and at least a bachelor’s or higher degree in a directly related specialty, or its equivalent, as a normal minimum entry requirement, as laid out on the current USCIS H-1B Specialty Occupations page. The most common categories are software engineering, finance, accounting, architecture, engineering disciplines, and natural sciences, but the definition is broader than most people assume.

What the H-1B is not: a self-petition. You cannot apply on your own. A US employer must sponsor you, file on your behalf, and take on significant regulatory obligations in the process. The employer pays the filing fees (in most cases), attests to your wage and working conditions, and bears responsibility for compliance throughout your stay.

The visa is granted for an initial period of three years, renewable for another three years, for a maximum of six years in standard H-1B status. Extensions beyond six years are possible if a green card application (specifically a PERM labor certification or an approved I-140 petition) has been pending for more than 365 days, but that path involves its own planning horizon.

One of the H-1B’s most important features is its dual intent. Unlike F-1 or B visas, the H-1B does not require you to maintain a foreign residence or demonstrate intent to return home. Holders can pursue permanent residency while on H-1B status without jeopardizing their visa.

What Happens Under the Annual Cap?

Most private-sector H-1B plans live or die at the cap-registration stage, before the employer can even file the full petition.

This is where most plans fall apart.

Congress has capped H-1B issuances at 85,000 new visas per fiscal year: 65,000 for the general pool, and an additional 20,000 reserved for applicants who hold a master’s degree or higher from a US institution. Petitions from certain exempt employers do not count against the cap.

Demand still exceeds supply, but the mechanics are no longer well described as a simple random lottery. USCIS now requires registrants to submit wage-level data and states that, if selection is necessary, it will conduct a weighted selection among properly submitted registrations for unique beneficiaries based generally on the highest OEWS wage level reflected in the registration. USCIS reported 343,981 eligible registrations for FY 2026 on that same official registration page.

The fiscal year begins on October 1. For the FY 2027 cap, USCIS announced that the initial registration period opens on March 4, 2026 and closes on March 19, 2026, with selected registrants notified by March 31. If a registration is selected, USCIS opens the filing window for the full H-1B petition. For most cap-subject cases, work cannot begin until October 1 at the earliest.

The March-to-October Gap

This timeline creates a practical challenge for European employers hiring from outside the US. If someone is selected in March and files in April, they may not be able to start until October 1, six months later. Companies need to plan around this gap: keep the candidate in their European office, bring them in on a B-1 business visa for discrete project work, or explore whether an L-1 or O-1 makes more sense for the initial transfer. See the visa comparison guide for a fuller breakdown of those alternatives.

Which Employers Are Cap-Exempt?

Universities and certain nonprofit or government research entities can avoid the annual cap, which changes the H-1B strategy completely.

Not all H-1B work is subject to the lottery. Cap-exempt employers include:

• Institutions of higher education
• Nonprofit organizations affiliated with universities
• Nonprofit research organizations
• Government research institutions

If an H-1B worker is already employed by a cap-exempt institution, they can be concurrently employed by a cap-subject employer without going through the lottery, provided the cap-exempt employment remains active. This is a narrow but real path that some candidates and companies use strategically.

Workers who have previously been counted against the cap and whose H-1B status has not lapsed by more than six consecutive years may be re-selected or may qualify for a cap-exempt transfer if they are simply changing employers.

What Makes a Role H-1B-Eligible?

H-1B eligibility depends on both sides of the case: the job must qualify as a specialty occupation and the worker must be properly qualified for that job.

The Position

The job itself must qualify as a specialty occupation. The position description, job duties, and educational requirement must all be consistent with the claim. USCIS scrutinizes job titles that are broadly defined or that could theoretically be performed by someone without a degree. Vague titles like “consultant” or “analyst” without rigorous supporting documentation routinely attract Requests for Evidence (RFEs).

The employer must demonstrate that a bachelor’s degree in a specific field is a normal and standard requirement for the role in question. A computer science degree for a software engineering role is straightforward. A history degree for a financial analyst role requires much more explanation.

The Worker

The beneficiary must hold at least a bachelor’s degree (or a foreign equivalent) in a field directly related to the position. Foreign degrees are accepted but must be evaluated by a credentials evaluation service. A German Diplom-Ingenieur in mechanical engineering, for example, is generally recognized as equivalent to a US bachelor’s in engineering, but the evaluation must be formally documented.

If the candidate does not hold a degree, USCIS allows a combination of education and professional experience to substitute, at a ratio of three years of specialized experience for each year of college-level education. This is harder to document and more likely to generate an RFE, so it is a fallback rather than a preferred approach.

Wage Compliance

Before filing the H-1B petition, the employer must file a Labor Condition Application (LCA) with the Department of Labor. The LCA attestation requires the employer to pay at least the prevailing wage for the occupation in the geographic area, or the employer’s actual wage for similarly situated employees, whichever is higher. The prevailing wage is determined by the Bureau of Labor Statistics Occupational Employment Statistics or by a private wage survey.

Prevailing wage levels are categorized from Level I (entry-level) to Level IV (fully competent). USCIS has historically scrutinized Level I wage certifications for positions that appear to require significant expertise, so salary planning should be conservative.

How Is the Petition Filed?

Once the registration and LCA steps are complete, the actual H-1B petition becomes a documentation exercise about the company, the role, and the worker.

Once selected in the cap process and past the LCA stage, the employer files Form I-129 (Petition for a Nonimmigrant Worker) with supporting documentation. Standard processing times vary, but premium processing remains available for H-1B petitions and gives a 15-business-day USCIS action window under current USCIS premium processing guidance.

One current wrinkle matters for cross-border hiring: USCIS now states that certain H-1B petitions filed on or after September 21, 2025 for beneficiaries outside the United States must include an additional $100,000 payment under a presidential proclamation, while purely domestic amendment, change-of-status, or extension cases are treated differently under the same policy.

Premium processing is almost always worth it. The certainty of knowing the outcome within three weeks, rather than waiting through a multi-month queue, has real operational value, especially when a hire is contingent on the outcome.

“A lot of H-1B problems start before the petition is filed, when the company has not pressure-tested whether the role really fits the specialty-occupation standard”, says Kari Foss-Persson, Esq., Managing Partner at Vinland Immigration.

The petition package typically includes:

• The approved LCA
• Evidence of the employer’s business (tax filings, client contracts, organization chart)
• Evidence of the specialty occupation (job description, industry wage surveys, expert opinion if needed)
• The beneficiary’s educational credentials and evaluation
• Copies of any prior immigration filings, if applicable

Requests for Evidence

A Request for Evidence is not a denial; it is a request for additional documentation. RFE rates for H-1B petitions have historically been high (above 20% in some fiscal years), particularly for IT consulting firms placing workers at third-party client sites. Responding effectively to an RFE requires understanding precisely what USCIS is questioning and providing targeted, well-organized evidence. Weak RFE responses lead to denials.

After Approval: Visa Stamp and Entry

An approved petition authorizes the classification, but applicants outside the United States still need visa issuance and admission at the border.

For beneficiaries outside the US, an approved I-129 petition is not itself a visa. They must apply for an H-1B visa stamp at a US consulate. The consular interview is generally straightforward for H-1B holders, but wait times at some posts have been long. For options and planning considerations around consular processing, see consular processing vs. adjustment of status and visa processing times.

Nationals of countries without a US consulate or facing very long wait times may be eligible to apply at a third-country post, though this has its own scheduling constraints.

H-1B Portability and Transfers

Portability lets some H-1B workers move faster between employers, but the rule is narrower and more technical than many summaries suggest.

One of the H-1B’s most valuable features for employees is portability. USCIS states that if you are changing H-1B employers, you may begin working for the new employer as soon as it properly files a non-frivolous Form I-129 on your behalf, or on the requested start date in that petition if later. There is no general 180-day employment threshold for basic H-1B portability; the real constraints are valid status, a timely filing, and a non-frivolous new petition.

For employers, portability means that poaching is real. A worker who has been on H-1B for more than six months can join a competitor the day the transfer petition is filed. Employers who invest in H-1B sponsorship should plan accordingly.

“The best H-1B planning is operational, not just legal; managers need to understand how location changes, promotions, and timing decisions can trigger new filings”, says Kari Foss-Persson, Esq., Managing Partner at Vinland Immigration.

Alternative Paths to Consider

The H-1B is not always the right starting point, especially when cap timing, entity structure, or the worker’s profile makes another category cleaner.

The H-1B is not always the right tool. Before committing to the lottery, it is worth considering whether another category better fits the situation.

O-1A. For individuals with extraordinary ability or achievement in their field (demonstrated through awards, publications, peer recognition, high salary, or leading roles in distinguished organizations), the O-1A has no lottery and no annual cap. The evidentiary bar is high, but for senior professionals with a strong record, it is often more reliable than the H-1B lottery. See the full guide on the O-1 for companies expanding to the US.

L-1. For European companies with an existing US entity (or willing to establish one), the L-1 intracompany transfer visa allows the transfer of managers, executives, and employees with specialized knowledge. No lottery, no cap. See the L-1 guide.

EB-1. If the goal is permanent residency, the EB-1 (particularly the EB-1A for extraordinary ability and EB-1B for outstanding professors and researchers) bypasses the labor certification process entirely. Priority dates are currently current for most nationalities, making it an efficient path for qualifying candidates. See the EB-1 green card guide.

Can H-1B Lead to a Green Card?

The H-1B is often a bridge to permanent residence, but only if the employer starts the green-card strategy early enough.

Many H-1B holders use the visa as a bridge to permanent residency. The employment-based green card process typically runs through three stages: PERM labor certification (a Department of Labor process demonstrating that no qualified US worker is available for the position), I-140 immigrant petition, and either adjustment of status (if already in the US) or consular processing.

For nationals of countries with long green card backlogs (notably India and China), the wait between an approved I-140 and an available visa number can stretch to decades. The visa bulletin and priority date guide explains how to track your place in the queue. For European nationals, current priority dates mean this is generally not a barrier.

European companies sponsoring H-1B workers should understand that initiating PERM early, ideally in the first three years of H-1B status, preserves the employee’s ability to extend beyond the six-year cap while the green card is pending. Waiting too long narrows the options.

Compliance Obligations

H-1B compliance continues long after approval because the employer’s wage, posting, and change-management duties remain active throughout the case.

H-1B compliance does not end at approval. Employers must:

• Maintain a public access file for each H-1B worker containing the LCA, wage documentation, and supporting materials
• Notify the Department of Labor if the worker is laid off or terminated before the petition expires
• Pay return transportation costs if the employee is terminated before the H-1B period ends
• File an amended petition if there is a material change in the terms of employment (change in job duties, geographic location, or salary below the LCA wage)

The “material change” rule catches many employers off guard. Compliance audits from the Department of Labor’s Wage and Hour Division are infrequent but not rare, and the consequences of a violation (back pay, debarment from the program) are significant.

Summary

The H-1B still works well for genuine specialty-occupation hiring, but it now requires more current planning than older lottery-era guides suggest.

The H-1B works for employers who need specialized talent and for professionals seeking to build a career in the US. Its limitations, particularly the lottery and the heavy compliance structure, make it more demanding than most alternatives. The path forward requires realistic timelines (plan for October 1 start dates, not immediate hires), rigorous documentation (weak petitions attract RFEs), proper wage planning (prevailing wage compliance is not optional), and an honest assessment of whether the H-1B is actually the best fit given the employer’s structure and the employee’s qualifications.

For most European companies new to US hiring, the first H-1B sponsorship is also an introduction to the wider infrastructure of US employment law and immigration compliance. Getting it right from the start is considerably easier than correcting it later.
