What Is the H-1B Visa?
The H-1B is a nonimmigrant visa category that allows U.S. employers to temporarily employ foreign nationals in specialty occupation positions. It is the primary work visa used by companies in technology, engineering, finance, accounting, architecture, medicine, and many other professional fields. Unlike some visa categories that are available only to citizens of specific countries or are restricted to certain industries, the H-1B is broadly available to workers of any nationality, as long as the position and the worker both meet the statutory requirements.
The H-1B is an employer-sponsored visa, meaning the employer — not the worker — initiates the process by filing a petition with the U.S. government. The worker cannot apply for an H-1B on their own behalf. The employer takes on legal responsibility for the worker’s wages and working conditions as part of the sponsorship process. This employer-centric structure is one of the most important things business owners need to understand about the H-1B, because it means that from the moment the petition is filed to the moment the employment relationship ends, the employer has ongoing legal obligations.
What Is a Specialty Occupation?
The defining characteristic of an H-1B position is that it must be a specialty occupation. The law defines a specialty occupation as one that requires the theoretical and practical application of a body of highly specialized knowledge, and that requires, at minimum, the attainment of a bachelor’s degree or its equivalent in a specific specialty as a condition of entry into the field. In plain English, this means two things: the job itself must be the kind of job that normally requires a bachelor’s degree in a particular field, and the worker must actually have that degree or its equivalent.
The classic examples of specialty occupations include software engineer, electrical engineer, mechanical engineer, architect, financial analyst, accountant, physician, and similar positions. What makes a position a specialty occupation is not just the presence of complex work, but the fact that entry into the field conventionally requires a specific bachelor’s degree. A highly skilled machinist or a gifted salesperson may do sophisticated, demanding work, but if the field does not normally require a specific bachelor’s degree for entry, it does not qualify as a specialty occupation.
USCIS has grown more demanding in recent years about what qualifies as a specialty occupation. The agency has scrutinized positions with broad or generic job descriptions, positions that mix specialty and non-specialty tasks, and positions in industries where hiring practices are inconsistent about degree requirements. Employers filing H-1B petitions need to document carefully why the specific position — not just the job title, but the actual duties of the role — requires a specific degree. A petition that says merely that the worker is a software engineer is far weaker than one that explains in detail the technical complexity of the work, the specific knowledge domains required, and why that knowledge is typically acquired through a degree program in computer science or a closely related field.
The Dual Requirement: Job and Worker Both Must Qualify
Qualifying for an H-1B requires satisfying two distinct requirements simultaneously. First, the position itself must qualify as a specialty occupation. Second, the individual worker must have the required degree. These two requirements are evaluated independently, and failing either one defeats the petition.
On the worker’s side, the requirement is that the worker holds a U.S. bachelor’s degree or a foreign equivalent in the specific field the position requires. Foreign degrees are evaluated for U.S. equivalency, typically through a credential evaluation by a recognized evaluation service. A worker who has a degree in an unrelated field, or who has work experience but no degree, does not automatically qualify. USCIS does recognize that in some fields, significant work experience can substitute for a degree — the general rule is that three years of relevant professional experience in the field is equivalent to one year of college education — but this equivalency analysis is complex and must be documented carefully by an expert, typically through an evaluation letter from a professional with credentials in the relevant field.
The Employer-Employee Relationship Requirement
One of the more nuanced requirements for the H-1B visa is that there must be a genuine employer-employee relationship between the sponsoring employer and the H-1B worker. USCIS looks at factors like who controls the worker’s day-to-day activities, who has the right to hire and fire the worker, who determines the worker’s work location and schedule, and who provides the tools and equipment needed to perform the work. The agency has used this requirement to deny petitions filed by staffing companies and consulting firms that place workers at client sites, on the theory that the actual employer-employee relationship is with the client, not the staffing company.
This has significant practical implications for consulting firms, IT staffing companies, and any other business whose model involves placing workers at third-party client sites. Such companies can and do sponsor H-1B workers, but they face heightened scrutiny from USCIS and must be prepared to demonstrate that they maintain meaningful control over the worker throughout the engagement. End clients also bear some responsibility: USCIS has the authority to request evidence from end clients confirming the nature of the work being performed and the supervisory structure.
What the Employer Must Pay and Provide
The H-1B program includes substantial wage protections for both the sponsored worker and the domestic workforce. Before filing an H-1B petition, the employer must obtain a certified Labor Condition Application from the Department of Labor. As part of that process, the employer attests that it will pay the H-1B worker the higher of two amounts: the actual wage paid to other employees in the same position at the worksite, or the prevailing wage for the occupation in that geographic area. The prevailing wage is determined by reference to government wage survey data and is designed to ensure that H-1B workers are not paid below-market wages that might disadvantage both the workers themselves and the U.S. workers they work alongside.
The employer must also provide the H-1B worker with the same working conditions and benefits offered to similarly situated U.S. workers. This means the H-1B worker must be eligible for the same health insurance, retirement plans, paid time off, and other benefits as comparable employees. The employer cannot offer an H-1B worker a stripped-down compensation package on the theory that the worker needs the sponsorship enough to accept worse terms.
There is also an important rule about who bears the cost of the H-1B process. Certain fees associated with the H-1B petition are legally required to be paid by the employer, not the employee. Specifically, the USCIS filing fees, the fraud prevention and detection fee, and the American Competitiveness and Workforce Improvement Act training fee must be paid by the employer. If an employer deducts these fees from an H-1B worker’s wages — even with the worker’s consent — it may be found to have paid wages below the required level, creating a violation of the LCA attestations.
Duration of H-1B Status and Extensions
An initial H-1B petition is approved for a period of three years. The employer can then file an extension petition for another three years, bringing the maximum standard H-1B period to six years. After six years in H-1B status, a worker must generally leave the United States for at least a year before they can again enter in H-1B status — unless the employer has taken steps to sponsor the worker for a green card. If a green card application has been pending with USCIS for more than 365 days, or if an immigrant visa petition has been approved but a green card is not yet available due to annual caps, the worker becomes eligible for one-year extensions of their H-1B status beyond the six-year limit, indefinitely, until the green card is either approved or the case is abandoned.
This intersection of the H-1B time limit and the green card process is one of the most important planning considerations for employers who want to retain H-1B workers long term. For workers born in countries with significant green card backlogs — most notably India — the wait for a green card can extend well beyond six years, meaning the employer must begin the green card process early enough to create the basis for H-1B extensions. Employers who wait until year five or six of an employee’s H-1B before initiating green card sponsorship may find themselves unable to keep the employee working legally in the United States.
What Happens If the Worker Changes Jobs
H-1B status is tied to a specific employer. If an H-1B worker leaves one employer and moves to another, the new employer must file a new H-1B petition before or at the time the worker begins working for the new company. Under a concept called H-1B portability, a worker who has an H-1B petition pending with a new employer may begin working for the new employer without waiting for the petition to be approved, as long as certain conditions are met. This portability provision is enormously important in a dynamic labor market and is discussed in detail in a separate article in this series.
What the worker cannot do is simply stop working for the sponsoring employer and begin working for a new employer without any government filing. Doing so would put the worker out of status — meaning they would be violating the terms of their visa — which can have serious consequences for their future immigration options, including bars on re-entry to the United States. Employers who hire workers in H-1B status from other companies need to move quickly and carefully to ensure the transfer petition is properly filed.
Cap-Exempt Employers and Institutions
Most H-1B petitions are subject to an annual numerical cap, which limits the number of new H-1B workers who can be approved in a given year. However, certain types of employers are exempt from this cap, meaning they can file H-1B petitions at any time of year and without competing in the lottery that governs cap-subject petitions. Cap-exempt employers include institutions of higher education — universities and colleges — as well as affiliated nonprofit entities and nonprofit or government research organizations. Workers who are currently in H-1B status with a cap-exempt employer can move to a cap-subject employer without going through the lottery, as long as they have previously been counted against the cap.
This cap-exempt status is a meaningful advantage for universities and research institutions that need to hire specialized faculty and researchers. It also creates a planning opportunity: workers who cannot secure an H-1B through the lottery might consider taking a position with a cap-exempt employer as a way to obtain H-1B status and then later transfer to a cap-subject employer.
H-1B1 and E-3: Related Categories for Specific Countries
Two related visa categories are worth noting for employers. The H-1B1 visa is available only to citizens of Chile and Singapore under free trade agreements. It functions similarly to the H-1B but has a separate annual cap and does not require USCIS to approve a petition — instead, it is processed directly at a U.S. consulate abroad. The E-3 visa is available only to Australian citizens in specialty occupations. Like the H-1B1, it has its own annual cap and can be renewed indefinitely in two-year increments. Both of these categories are significantly underused relative to their caps, meaning eligible workers from Chile, Singapore, and Australia can often obtain work authorization more quickly and with less uncertainty than workers who must go through the H-1B lottery.
The Petition Process in Brief
Filing an H-1B petition involves several steps. The employer first obtains a certified Labor Condition Application from the Department of Labor, which involves posting notice to employees and attesting to wage and working condition obligations. The LCA certification typically takes about seven business days through the DOL’s electronic system. Once the LCA is certified, the employer files the H-1B petition with USCIS, which includes the petition form, supporting documentation about the employer and the position, evidence of the worker’s qualifications, and filing fees. USCIS offers a premium processing service for an additional fee, through which the agency commits to adjudicating the petition within a specified timeframe — currently fifteen business days. Without premium processing, adjudication can take several months.
Employers filing H-1B petitions for new hires who are not already in H-1B status — for example, recent graduates on student visas, or workers currently outside the United States — must navigate the annual cap and lottery, which is covered in the next article in this series. Employers filing for workers who are already in H-1B status with another employer, or extending status for a current employee, generally do not face the same lottery constraints and can file at any time.
