H-1B visa definition: specialty occupation rules, sub-classifications and stay limits

The H-1B visa is a temporary US nonimmigrant work classification. It lets employers hire foreign professionals in specialty occupations that require highly specialized knowledge and at least a bachelor's degree in a directly related field. Under USCIS rules, Congress limits new cap-subject approvals to 65,000 each fiscal year, plus 20,000 for workers with a US master's degree or higher. Initial admission lasts up to 3 years and can extend to 6 years total.

What is the legal definition of an H-1B visa?

Under US immigration law, the H-1B nonimmigrant classification applies to foreign workers coming to the United States temporarily to perform services in a specialty occupation, to work on a Department of Defense (DOD) cooperative research and development or coproduction project, or to work as a fashion model of distinguished merit and ability.

The Department of Labor states that the purpose of the H-1B provisions is to help employers that cannot otherwise obtain needed business skills and abilities from the US workforce by authorizing the temporary employment of qualified individuals. You cannot apply for an H-1B on your own. A US employer or agent must petition for you by filing Form I-129, Petition for a Nonimmigrant Worker, with USCIS.

USCIS divides the H-1B classification into distinct categories based on the work performed and applicable trade agreements. The table below compares the core H-1B sub-classifications and related specialty worker categories.

What qualifies as an H-1B specialty occupation?

A specialty occupation requires two things under USCIS and Department of Labor rules. First, the job must require theoretical and practical application of highly specialized knowledge. Second, it must require at least a bachelor's degree or its equivalent in a directly related specific specialty as the minimum entry requirement in the United States. Common fields listed by USCIS include architecture, engineering, mathematics, physical sciences, social sciences, medicine and health, education, business specialties, accounting, law, theology, and the arts.

Under federal regulations at 8 CFR 214.2(h)(4)(ii), directly related means there is a logical connection between the required degree, or its equivalent, and the duties of the position. The word normally in these criteria means conforming to a type, standard, or regular pattern that is considered usual, typical, common, or routine. USCIS specifies that normally does not mean always.

In addition to the general definition, the offered position must meet at least one of four regulatory criteria under 8 CFR 214.2(h)(4)(iii)(A):

• A US bachelor's or higher degree in a directly related specific specialty, or its equivalent, is normally the minimum entry requirement for the particular occupation.
• A US bachelor's or higher degree in a directly related specific specialty, or its equivalent, is normally required to perform job duties in parallel positions among similar organizations in the employer's industry in the United States.
• The employer, or the third party if the worker will be staffed to a third party, normally requires a US bachelor's or higher degree in a directly related specific specialty, or its equivalent, to perform the job duties of the position.
• The specific duties of the offered position are so specialized, complex, or unique that the knowledge required to perform them is normally associated with the attainment of a US bachelor's or higher degree in a directly related specific specialty, or its equivalent.

How do you qualify as an H-1B worker?

Defining the job as a specialty occupation is only half of the eligibility test. You must also prove that you personally hold the credentials required to perform the services.

When an employer files a cap-subject petition, they must submit evidence of your educational credentials, with English translations when applicable, at the time of filing. If you have met all requirements for your degree but the diploma has not yet been awarded, USCIS accepts a copy of your final transcript or a letter from the registrar confirming that you met all degree requirements.

If your profession requires a state or local license to practice fully in the state of intended employment, 8 CFR 214.2(h)(4)(v)(A) through (B) generally requires that you hold that license before the H-1B petition is approved, rather than at the time the petition is filed. If a license is required and no evidence is included, USCIS generally issues a Request for Evidence.

Under USCIS criteria and 8 CFR 214.2(h)(4)(iii)(C), you must meet one of four worker qualification paths:

• Hold a US bachelor's or higher degree required by the specialty occupation from an accredited college or university.
• Hold a foreign degree that is equivalent to a US bachelor's or higher degree required by the specialty occupation from an accredited college or university.
• Hold an unrestricted state license, registration, or certification that authorizes you to fully practice the specialty occupation and be immediately engaged in that specialty in the state of intended employment.
• Have education, specialized training, or progressively responsible experience that is equivalent to the completion of a US bachelor's or higher degree in the specialty occupation, and have recognition of expertise in the specialty through progressively responsible positions directly related to the specialty.

What are the employer's Labor Condition Application (LCA) obligations?

Before an employer can file Form I-129 with USCIS for a specialty occupation worker or fashion model, the employer must submit Form ETA-9035/9035E, Labor Condition Application (LCA), to the Department of Labor and receive certification. Employers submit the LCA electronically through the Department of Labor's Foreign Labor Application Gateway (FLAG) system. Mail filing on Form ETA-9035 is allowed only with advance permission for employers with physical disabilities or no internet access.

An LCA cannot be submitted more than 6 months before employment begins. The Department of Labor reviews LCAs within 7 working days for completeness and obvious errors. By signing the LCA, the employer makes four mandatory attestations. Violating these attestations can lead to civil money penalties, bars on petition sponsorship, and random investigations for up to 5 years for willful violators:

• Wage requirement: Pay the H-1B worker at least the actual wage paid by the employer to other workers with similar experience and qualifications for the job, or the prevailing wage for the occupation in the geographic area of intended employment, whichever is greater.
• Working conditions: Provide working conditions that will not adversely affect other similarly employed US workers.
• No strike or lockout: Confirm that at the time of filing the LCA, there is no strike or lockout in the course of a labor dispute at the place of employment.
• Notice to workers: Provide notice of the LCA filing to the union bargaining representative, or if there is no union representative, post the notice at the place of employment or electronically.

How do the H-1B cap and selection lottery work?

Congress limits the number of new H-1B statuses or visas available each fiscal year to a regular cap of 65,000, plus an advanced degree exemption (known as the master's cap) of 20,000 for beneficiaries who have earned a master's degree or higher from a US institution of higher education. Up to 6,800 visas from the 65,000 regular cap are set aside annually for H-1B1 workers from Chile (1,400) and Singapore (5,400), and any unused H-1B1 numbers roll into the next fiscal year's regular H-1B cap.

For cap-subject roles, employers must first register each prospective worker electronically during an initial registration window that lasts at least 14 calendar days. USCIS uses a beneficiary-centric selection process, meaning each worker is counted as a unique beneficiary using their valid passport or travel document information, regardless of how many employers register for them. In FY 2026, USCIS recorded 343,981 eligible registrations for about 339,000 eligible unique beneficiaries (an average of 1.01 registrations per beneficiary) and selected 120,141 registrations. By our calculation from USCIS's FY 2026 historical registration table, 336,153 of those 343,981 eligible registrations (97.7 percent) were for beneficiaries with only a single registration, and 120,141 selections out of 343,981 eligible registrations represented a 34.9 percent selection rate.

Certain employers and locations are exempt from the annual numerical cap and can file petitions year-round without entering the lottery:

• Institutions of higher education and their affiliated or related nonprofit entities.
• Nonprofit research organizations and government research organizations.
• Employers filing before December 31, 2029, for H-1B workers performing labor or services in Guam or the Commonwealth of the Northern Mariana Islands (CNMI).

How long does H-1B status last, and when can it extend past 6 years?

An H-1B specialty occupation worker may generally be admitted for an initial period of up to 3 years, which may be extended for an additional period of up to 3 years, for a maximum stay of 6 years. However, if you hold a controlling interest in the petitioning organization (meaning you own more than 50 percent of the petitioner or have majority voting rights), USCIS limits both your initial petition approval and your first extension approval to a validity period of up to 18 months each.

If your employer terminates your employment before the end of your period of authorized stay, the employer is legally liable for the reasonable costs of your return transportation abroad. This rule does not apply if you voluntarily resign.

USCIS regulations provide two primary ways to extend your H-1B stay beyond the 6-year limit while you pursue lawful permanent residence:

• Up to 3-year extensions under 8 CFR 214.2(h)(13)(iii)(E): Available if you are the beneficiary of an approved employment-based immigrant visa petition in the EB-1, EB-2, or EB-3 classification and are eligible for that status except that an immigrant visa number is unavailable due to per-country or worldwide limits as of the date the H-1B petition is filed.
• Up to 1-year extensions under 8 CFR 214.2(h)(13)(iii)(D): Available if at least 365 days have passed since a permanent labor certification was filed with the Department of Labor on your behalf (if required) or since an immigrant visa petition was filed with USCIS on your behalf. You generally lose eligibility for this 1-year extension if you fail to file an adjustment of status application or apply for an immigrant visa within 1 year of an immigrant visa becoming available, unless USCIS excuses the delay based on circumstances beyond your control.

How do H-1B portability, job changes, and H-4 dependents work?

Because an H-1B is employer-specific and position-specific, changing employers or changing employment terms with the same employer requires a new Form I-129 petition. Under H-1B portability rules, if you are maintaining lawful status and have not worked without authorization since your last admission, you may begin working for a new H-1B employer as soon as that employer properly files a non-frivolous Form I-129 petition on your behalf before your current authorized stay expires, or on the requested start date on the new petition, whichever is later.

If you are laid off, fired, quit, or otherwise stop working for your employer, USCIS provides a grace period of up to 60 consecutive days, or until the end of your current authorized validity period, whichever is shorter. During that window you can have a new employer file a petition, apply to change your nonimmigrant status, or depart the United States. Moving from a cap-exempt employer (such as a university) to a private cap-subject employer requires a selected cap registration unless you were previously counted toward the cap or work concurrently for both the cap-exempt and cap-subject employers.

Your spouse and unmarried children under 21 years of age may apply for admission in the H-4 nonimmigrant classification. If they are inside the United States and need to extend or change their status to H-4, they file Form I-539, Application to Extend/Change Nonimmigrant Status. Certain H-4 dependent spouses can apply for work authorization by filing Form I-765, Application for Employment Authorization, once the H-1B worker has started specific stages of seeking employment-based lawful permanent resident status.

Step-by-step H-1B filing checklist and fee rules

Whether your petition is cap-subject or cap-exempt, USCIS and the Department of Labor require a strict sequence of filings. Use this step-by-step checklist to verify that every stage is completed in order:

Filing an H-1B petition involves fees that vary depending on the petition type. USCIS publishes all petition and service fees on Form G-1055, Fee Schedule, and rejects any petition submitted with an incorrect filing fee. The non-refundable electronic registration fee for each cap-subject beneficiary is $215 (uscis.gov, as of September 2026).

• Step 1 (Cap-subject roles only): Submit the electronic registration in your USCIS account during the initial March registration window with the beneficiary's valid passport or travel document details.
• Step 2 (All specialty occupation and fashion model petitions): File Form ETA-9035E electronically in the Department of Labor's FLAG system no more than 6 months before the employment start date, post the required worksite or electronic notice, and receive the certified LCA.
• Step 3: File Form I-129 with USCIS, including the H Classification Supplement, the H-1B Data Collection and Filing Fee Exemption Supplement, the certified LCA, educational credentials, and (if cap-subject) the Registration Selection Notice.
• Step 4: Once USCIS approves Form I-129 on Form I-797, workers inside the United States with an approved change of status begin H-1B employment on the petition start date, while workers outside the United States apply for an H-1B visa at a US embassy or consulate and seek admission from Customs and Border Protection.

Practice example

What are your specific job duties in the United States, and how does your bachelor's or master's degree directly relate to this position?

A strong, honest answer states your exact job title and describes two or three core technical duties in plain language, then connects those duties directly to the specialized coursework or training from your degree. Before your appointment, review the job description on your employer's Form I-129 petition and the Standard Occupational Classification (SOC) code and wage level listed on your certified Labor Condition Application (Form ETA-9035). Be ready to name your degree field and explain the logical connection between what you studied and the work you will perform each day, especially if your degree title differs slightly from your job title or if you qualified through a combination of education and progressive experience. Keep a copy of your Form I-797 approval notice, your certified LCA, and your diploma or final transcripts organized in your folder in case the officer asks to inspect them.

The consular officer is checking that your offered role meets the regulatory definition of an H-1B specialty occupation and that your degree is directly related to the position's duties, matching what your employer attested on Form I-129 and the LCA.
