What Is an H-1B Visa? A Guide for Employers Sponsoring Specialty Workers

Sponsoring international talent through the H-1B visa program is common practice for companies in technology, engineering, finance, healthcare, and other fields competing for specialized expertise. But the process comes with real employer obligations, from the initial petition through the annual cap and lottery to ongoing wage and compliance requirements. This guide walks through what employers need to know before, during, and after sponsorship, so the process feels manageable rather than overwhelming.

What Is an H-1B Visa?

The H-1B is a nonimmigrant visa category that allows US employers to temporarily employ foreign nationals in specialty occupations. A specialty occupation requires the theoretical and practical application of highly specialized knowledge, typically at least a bachelor's degree or its equivalent in a specific field.

Common fields include technology, engineering, mathematics, architecture, accounting, medicine, and law. The visa is tied to the sponsoring employer and the specific role, not to the worker independently.

H-1B status is granted for an initial period of up to three years and can be extended to six years total, with further extensions available for workers in certain stages of the green card process.

The H-1B Annual Cap and Lottery

USCIS caps H-1B approvals at 65,000 per fiscal year, plus an additional 20,000 for workers with a US master's degree or higher, for a combined cap of 85,000.

When demand exceeds the cap, which happens most years, USCIS conducts a random lottery among registered petitions. Selection is not merit-based.

Employers must register during the lottery window, typically in March. If selected, they may then file a full petition. Plan around this timeline, since workers who are not selected must wait for the next cycle.

Cap-exempt employers, such as universities, nonprofit research organizations, and government research institutions, are not subject to the annual cap and may file at any time.

What Employers Are Responsible For

Sponsoring an H-1B worker comes with several employer obligations:

• Filing the Petition: The employer, not the employee, files Form I-129 with USCIS. Immigration counsel is standard practice and strongly recommended.
• Prevailing Wage Compliance: Employers must pay H-1B workers at least the prevailing wage for the role in the geographic area, as determined by the Department of Labor. Paying below prevailing wage is a compliance violation with significant penalties.
• Labor Condition Application (LCA): Before filing the H-1B petition, the employer must obtain a certified LCA from the Department of Labor. The LCA certifies that the employer will pay the prevailing wage and will not adversely affect working conditions of US workers.
• Public Access File: Employers must maintain a public access file containing the LCA and supporting wage documentation, available for inspection upon request.
• Fees: Employers are responsible for required government filing fees, covered in detail below.

What Employers Should Know About Cost

Government fees for H-1B petitions typically total several thousand dollars per filing, and USCIS periodically adjusts the fee schedule. Confirm current amounts on the USCIS website before budgeting.

Premium processing, which guarantees a decision within a defined business day window, is available for an additional fee and is commonly used by employers who need a faster turnaround.

Employers cannot charge the employee for certain mandatory fees, including the base filing fee and the ACWIA training fee. Legal counsel fees are at the employer's discretion.

Key Compliance Considerations

A few practical points shape day-to-day H-1B compliance:

• Staying Within Scope: H-1B workers may only work for the sponsoring employer in the approved role and location. If the job duties, title, or worksite changes materially, an amended petition may be required.
• Site Visit Readiness: USCIS conducts unannounced site visits to verify H-1B compliance. Employers should be prepared to produce documentation confirming the employee's role, worksite, and wage.
• No Benching: Employers cannot place H-1B workers in nonproductive status without pay. If there is no work available, the employer is still required to pay the required wage.
