H-1B Visa: Everything Employers and Workers Need to Know

The H-1B visa is the most common employment-based nonimmigrant visa in the United States, and it is the primary pathway through which US technology companies, universities, hospitals, research institutions, and many other employers hire foreign nationals for professional positions. Understanding how the program works, how the annual lottery operates, and what the long-term immigration implications are is essential knowledge for both employers and foreign professionals navigating the US immigration system.

The demand for H-1B visas dramatically exceeds the annual cap of 85,000 new visas, creating an annual lottery that most applicants enter year after year before their numbers are selected. The process from lottery selection through visa issuance to eventual green card has become so protracted for workers from India and China, the two most common countries of origin, that it spans decades for many people.

This guide explains the eligibility requirements, the annual lottery process, employer obligations, the worker's rights within the H-1B relationship, and the pathway from H-1B status toward permanent residence.

H-1B Eligibility: Specialty Occupation and Employer Requirements

The H-1B visa authorizes a foreign national to work for a specific US employer in a specialty occupation, defined as an occupation that requires at least a bachelor's degree or its equivalent in a specific academic field as a minimum qualification. The employer must file a petition on behalf of the worker; H-1B is employer-sponsored and the worker cannot petition for themselves.

Whether a particular position qualifies as a specialty occupation is one of the most frequently contested issues in H-1B adjudication. USCIS evaluates whether the theoretical and practical application of specialized knowledge typically associated with at least a bachelor's degree is required to perform the duties of the position. Generic, entry-level, or supervisory positions that do not require specialized degree-level knowledge may not qualify as specialty occupations even if the employer typically hires college graduates for them.

The employer must also comply with the Labor Condition Application requirements, which impose wage obligations. The employer must pay the H-1B worker the higher of the actual wage paid to other similarly employed workers at the same location or the prevailing wage for the occupation in the geographic area. This requirement is designed to ensure that H-1B workers are not used to undercut US worker wages, and compliance with the LCA is a legal obligation that the Department of Labor can enforce.

The Annual H-1B Lottery

Each fiscal year, USCIS receives far more H-1B petitions than the 85,000 cap allows. When this happens, USCIS conducts a random lottery among all eligible registrations to determine which petitions will be selected for processing. The lottery now operates through a pre-registration process in which employers register their prospective H-1B workers electronically during a specified registration window, typically in March for an October 1 start date.

Registrations selected in the lottery are then invited to file full H-1B petitions during a specified filing window. The lottery is conducted in two rounds: the first selects enough registrations to fill the master cap of 65,000, and the second selects enough from the remaining pool of those with US advanced degrees to fill the 20,000 advanced degree exemption slots. Workers with US advanced degrees are effectively entered in both rounds, which gives them a slightly higher overall selection probability.

The unpredictability of the lottery creates significant challenges for employers and workers who must plan for the possibility that a lottery registration will not be selected. Workers who are not selected face continuing their current status if they have one, or departing the United States if their current authorization is expiring. Employers sometimes pursue cap-exempt H-1B positions at universities or nonprofit research institutions as an alternative while awaiting lottery selection.

H-1B Worker Rights and Employer Obligations

H-1B workers have specific rights that USCIS and the Department of Labor enforce, and that are important for workers to understand because violations by employers are not uncommon. The employer must pay the H-1B worker the required wage even if the worker is not working, a concept called the benching prohibition. An employer cannot make the H-1B worker pay for the visa petition filing fees or for the costs of portability arrangements.

H-1B workers are authorized to work only for the specific employer who filed their petition, at the specific location or locations specified in the petition. Working for a different employer without a separate H-1B petition, or working at a materially different location without an amendment, violates the terms of the status. H-1B portability provisions allow workers who have been with the same employer for a certain period to transfer to a new employer upon the filing of a new H-1B petition without waiting for approval.

USCIS maintains a public access file requirement for H-1B employers, which requires that certain LCA documents be available for public inspection at the employer's principal place of business and at each worksite location. Employees, the public, and enforcement agencies can request access to these files to verify wage and other compliance.

H-1B to Green Card: The Long Path to Permanent Residence

The H-1B visa is the most common starting point for employment-based green card sponsorship, but the journey from H-1B status to permanent residence is lengthy and involves multiple USCIS petitions and in some cases labor market testing through the PERM process. The employer typically initiates the green card process by sponsoring the worker for an employment-based immigrant visa petition.

Workers born in India and China face multi-decade wait times for their green cards due to the per-country limits on employment-based immigrant visa numbers and the enormous demand from those countries. Workers born in other countries typically wait much shorter periods. During the wait, H-1B extensions beyond the standard six-year maximum are available under the American Competitiveness in the Twenty-First Century Act when the worker has an approved immigrant visa petition and cannot yet adjust status due to visa number unavailability.

The human impact of these wait times is profound. Workers who entered the H-1B system in their 20s or 30s may not receive their green cards until their 40s or 50s, spending decades in an immigration limbo that limits their job mobility, creates anxiety about their status, and affects their ability to plan for the future. Legislative reform efforts have addressed this issue periodically but have not yet produced a comprehensive solution.

Final Thoughts

The H-1B program is the backbone of employment-based skilled worker immigration in the United States, and it serves as the starting point for the careers and immigration journeys of hundreds of thousands of professional workers each year. Understanding its requirements, its limitations, and its pathway to permanent residence is essential knowledge for both employers who use it and workers whose lives depend on it.

The annual lottery, the employer dependency, and the decades-long green card wait for workers from certain countries create real hardships that deserve acknowledgment alongside the program's genuine value to the US economy. Workers navigating the system deserve experienced immigration counsel and employers deserve advisors who can manage compliance and petition quality.

Whether you are an employer seeking to sponsor a foreign professional or a worker navigating the H-1B system toward permanent residence, understanding the full picture of the program gives you the foundation to make sound decisions at each stage.
