How to Fill Out and File the I-129 H Classification Supplement

The H Classification Supplement to Form I-129 is the section every employer completes when petitioning for a foreign worker in any H category. It begins on page 13 of the I-129 packet and collects the beneficiary’s prior time in H or L status, the specific H classification requested, and details about the job or training program. You complete the shared fields at the top, select exactly one H sub-classification, and then fill in only the section that matches that box, leaving the rest blank.

Where to Find the Supplement

The current edition of Form I-129 (02/27/26) includes the H Classification Supplement and is a free PDF download from the USCIS website.¹ The supplement runs several pages: general information fields that apply to all H petitions come first, followed by classification-specific sections for H-1B, H-2A/H-2B, and H-3.

Choose the Right Sub-Classification

Item 4 on the first page of the supplement lists every H sub-classification. Select one box, and only one:

H-1B1: Free-trade specialty workers from Chile or Singapore
H-1B: Specialty occupation (the most common H category)
H-1B2: Workers on cooperative research and development projects administered by the Department of Defense
H-1B3: Fashion models of distinguished merit and ability
H-2A: Temporary agricultural workers
H-2B: Temporary non-agricultural workers
H-3: Trainees or special education exchange visitors

Selecting the wrong box or leaving it blank will trigger a request for evidence and delay the case, so verify this field before you submit.

General Fields Every H Petitioner Completes

The shared fields at the top of the supplement ask for the petitioner’s legal name, the beneficiary’s full name, and how many workers the petition covers.

Item 3 requires every prior period the beneficiary spent in the United States in H or L status during the last six years. For H-2A and H-2B beneficiaries, list only the last three years.² Only include periods when the beneficiary was physically present and in H or L status; do not list time spent as an H-4 or L-2 dependent. Enter the start date, end date, and classification held for each entry. USCIS uses this chart to count how much of the six-year H-1B maximum remains.³

Items 6 and 7 address the Guam-CNMI cap exemption under Public Law 110-229. Most petitioners answer “no” to both. Items 8a and 8b ask whether the beneficiary holds a controlling interest in the petitioning organization, a question aimed at detecting self-petitioning, which is not permitted for most H classifications.

H-1B and H-1B1 Specialty Occupation Section

The H-1B section is the most detailed part of the supplement. It opens with two narrative fields: a description of the proposed duties and a summary of the beneficiary’s current occupation and prior work experience. Generic descriptions are one of the top reasons USCIS issues a request for evidence, so be specific about daily tasks, the tools or systems involved, and the minimum degree field the job requires.²

Labor Condition Application Attestation

Every H-1B and H-1B1 petition must be supported by a certified Labor Condition Application (LCA) from the Department of Labor. The supplement includes an attestation the petitioner signs agreeing to abide by the LCA’s terms, which commit the employer to pay at least the higher of the actual wage (what you pay other employees in the same role) or the prevailing wage for that occupation and area.⁴ The petitioner also certifies that working conditions will not adversely affect other similarly employed workers. These attestations are legally binding; false statements can result in civil penalties and debarment from the foreign labor certification program.

The LCA’s ETA case number and validity dates appear on Form I-129’s main body rather than the supplement, but the supplement’s attestation ties back to those dates. Confirm the employment period requested on the petition falls entirely within the LCA’s validity window.

Cap Selection and Exemptions

If the beneficiary was selected in the H-1B cap lottery, Item 5 asks for the confirmation number from the H-1B Registration Selection Notice, along with the passport or travel document number used at registration.⁵ Cap-exempt petitioners, typically institutions of higher education, nonprofit research organizations, and government research entities, skip the registration process and file year-round without a selection notice.

One item on the main I-129 (Part 6) sits outside the supplement but is easy to miss: it asks whether the beneficiary will need access to technology controlled under the Export Administration Regulations or the International Traffic in Arms Regulations. Leaving Part 6 blank triggers an RFE, and failure to respond results in denial.⁶

H-2A and H-2B Temporary Worker Section

If you checked H-2A (agricultural) or H-2B (non-agricultural), Section 2 applies. The core of this section is showing that the employer’s need for labor is genuinely temporary and that qualified U.S. workers are not available. Both classifications require a temporary labor certification from the Department of Labor before the I-129 can be filed.

Categorizing the Temporary Need

The supplement provides checkboxes for the type of temporary need. USCIS recognizes four categories:

Seasonal: the need is tied to a predictable season or recurring event, and the employer can identify the months when the labor is not needed.
Peakload: the employer has a permanent workforce but needs extra hands for a short-term spike. The temporary additions cannot become part of regular operations.
Intermittent: the employer does not maintain permanent full-time workers for this role but occasionally needs temporary help for short periods.
One-time occurrence: a specific, non-recurring event creates a temporary need that will not repeat.

These labels matter because USCIS will deny a petition if the need looks permanent.⁷

Fee and Recruitment Attestations

Items 8 through 13 ask whether the petitioner or any agent has collected prohibited fees from workers, including recruitment fees, job-placement charges, or reimbursement for petition costs. The employer must also attest that the position is not vacant because of a strike or lockout, a provision that applies to both H-2A and H-2B petitions. Items 14 through 19 cover prior debarment orders, revoked labor certifications, and any findings of fraud or willful misrepresentation on earlier petitions.

H-3 Trainee Section

The H-3 trainee category is not for productive employment. The point is structured training that benefits the beneficiary’s career abroad, and USCIS reviews these petitions closely.

The supplement requires a detailed description of the training program, and the petition package must include a written statement covering:

The type of training and how it will be supervised
A fixed schedule showing hours in classroom instruction versus on-the-job training
Why the training is unavailable in the beneficiary’s home country
How the training prepares the beneficiary for a specific career outside the United States
The proportion of time devoted to productive employment, which must be minimal

A program that deals in generalities with no fixed schedule, measurable objectives, or means of evaluation will not be approved.⁸ A vague proposal like “the trainee will learn business operations” without a week-by-week outline will draw a denial or an RFE.

Fees to Send With the Petition

The I-129 comes with a base filing fee plus several add-ons that depend on classification and employer size. Submitting the wrong amount will get the entire package rejected, so verify every line item on the USCIS fee schedule (Form G-1055) before mailing.¹

Two fees apply across H classifications: the base I-129 filing fee, and the Asylum Program Fee of $600 for employers with more than 25 full-time equivalent employees, $300 for those with 25 or fewer, and $0 for nonprofits.⁹

H-1B petitions carry additional charges:

ACWIA Training Fee: $1,500 for employers with 26 or more full-time equivalent U.S. employees; $750 for employers with 25 or fewer. The supplement’s attestation section prohibits passing this cost to the beneficiary.¹⁰
Fraud Detection and Prevention Fee: $500, required for initial H-1B filings and certain change-of-employer petitions.
H-1B-dependent employer fee: $4,000 per petition for companies with 50 or more U.S. employees where more than 50 percent hold H-1B or L-1 status.
Registration fee: $215 per beneficiary for the annual H-1B cap lottery.¹¹

An H-1B petition from a mid-size employer (26 or more employees, not H-1B-dependent) can easily exceed $3,000 before attorney fees; a petition from a large H-1B-dependent firm can exceed $7,000.

Where and How to File

USCIS now accepts Form I-129 both online through a USCIS online account and by mail, though not all classifications are available for online filing yet. H-2A petitions can only be filed online.¹² Check the USCIS “Forms Available to File Online” page for your specific classification.

Paper filings go to a USCIS lockbox facility, not directly to a service center. The correct lockbox depends on the H classification and, for H-1B, on the state where the petitioner’s primary office is located. H-1B filings are split across lockbox facilities in Dallas, Phoenix, Chicago, and Elgin, Illinois. H-3 petitions go to a single address in Montclair, California. Confirm the current address on the USCIS direct filing addresses page before mailing, and use a courier service or certified mail with tracking. A package sent to the wrong lockbox will be rejected and returned.

After You File

Once USCIS accepts the filing, it issues Form I-797C, Notice of Action, which serves as proof of receipt and carries the receipt number you use to track the case through Case Status Online.¹³ The I-797C is only a receipt; it does not approve anything.

Standard processing runs roughly three to seven months, depending on classification and workload. Employers who need a faster answer can add Form I-907 and pay for premium processing, which guarantees USCIS action within 15 business days. That action may be an approval, a denial, an RFE, or a notice of intent to deny.¹⁴ As of March 1, 2026, the premium processing fee is $2,965 for most H-1B and H-3 filings and $1,780 for H-2B petitions.¹⁵

If USCIS issues a request for evidence, respond within the deadline stated on the notice, usually 60 or 84 days. Missing that deadline results in denial. Common H-1B RFE triggers include vague job descriptions that raise specialty occupation doubts, weak documentation of the employer-employee relationship at third-party client sites, insufficient proof of work for the full requested period, and questions about whether the beneficiary’s degree matches the position.

When the petition is approved, USCIS sends Form I-797B to the petitioner.¹⁶ A beneficiary abroad uses the I-797B to apply for an H visa stamp at a U.S. consulate. A beneficiary already in the country under a petition that included a change or extension of status uses the I-797 itself as proof of the new status.
