USCIS Will Reject Outdated Form I-129 for FY2027 H-1B Petitions Starting April 1

(UNITED STATES) — USCIS will reject Form I-129 petitions postmarked on or after April 1, 2026, if employers use the prior 01/20/25 edition instead of the new 02/27/26 edition.

The agency’s change takes effect immediately on that date. Only the 02/27/26 edition, released February 27, 2026, will be accepted for filings sent on or after April 1, 2026.

Employers still can use the prior edition for petitions received on or before March 31, 2026. After that, the cutoff is strict, with no transition grace period beyond March 31, 2026.

Form I-129 is the petition U.S. employers file for nonimmigrant workers. The form covers categories that include H-1B, H-2A, H-2B, H-3, L-1, O-1, O-2, P-1, P-2, P-3, Q-1, and R-1.

The April 1 shift reaches only I-129 petitions. It does not affect other USCIS forms or broader work visa categories beyond I-129 petitions.

At the center of the update is the FY2027 H-1B cap season. The new edition supports that season under the wage-weighted lottery system and adds fields that require employers to provide more detail about the jobs they are offering.

Those added fields include minimum educational qualifications, the specific field of study, required work experience, and whether the role involves supervisory responsibilities. The revised form also captures the wage level from the Labor Condition Application, or LCA, and the wage level selected during H-1B registration.

USCIS will use that data to verify wage levels I to IV and align them with Department of Labor criteria. Inconsistencies may trigger Requests for Evidence, or RFEs, or denials.

For employers preparing cap-subject filings, timing matters. FY2027 H-1B cap-subject petitions open that day, making April 1, 2026, both the filing date for many cases and the point when the prior edition stops working for newly postmarked submissions.

That overlap raises the stakes for petitioners who file in the H-1B program. A package sent on or after April 1, 2026, with the 01/20/25 edition will be rejected, even if the employer prepared the filing before the deadline.

The postmark date controls the rule. USCIS applies the rejection standard strictly to petitions postmarked on or after April 1, 2026.

That means employers must check the edition date at the bottom of the form and the instructions before mailing a petition. They also must use the new form for all filings postmarked April 1, 2026, or later.

The agency’s direction is straightforward: download the latest version from the USCIS website before filing. The purpose is to avoid automatic rejection and the delays that follow when an employer has to prepare and resend a package.

For employers that handle multiple worker categories through one petition type, the change spans more than the H-1B process. Form I-129 also covers H-2A, H-2B, H-3, L-1, O classifications, P classifications, Q-1, and R-1, so the edition-date check applies across a broad range of nonimmigrant worker filings.

That makes the revision an administrative issue as much as a policy one. A filing can fail at intake for using the wrong edition, even before USCIS reviews the substance of the petition.

The new data requests also point to closer matching between the position described during H-1B registration and the position described in the petition. USCIS says the added information helps it verify the wage level chosen in registration and the wage level listed on the Labor Condition Application.

The form now asks employers to spell out the minimum educational qualifications tied to the role. It also asks for the specific field of study rather than leaving the educational requirement at a general level.

Work experience gets the same treatment. Employers must identify required work experience and indicate whether supervisory responsibilities are part of the position.

Those details feed into the wage-level review. USCIS says the information helps it assess whether a position fits the wage level identified as I, II, III, or IV and whether that aligns with Department of Labor criteria.

When those data points do not match, employers may face follow-up from the agency. Inconsistencies may trigger RFEs or denials.

That matters for the FY2027 H-1B season because the revised form arrives alongside the wage-weighted lottery system. The update is not a separate filing track; it is built into the petition employers must use when moving from selection to a cap-subject filing.

In practice, that means the new edition is not only a formatting change. It adds information that USCIS will use in reviewing whether the petition aligns with earlier wage selections and the job details tied to the filing.

The agency has also drawn a bright line around the transition period. The prior 01/20/25 edition remains valid only for petitions received on or before March 31, 2026, and rejections apply strictly based on postmarked dates after that.

That cutoff leaves no extra filing cushion into April. Employers that wait until the deadline day to print or assemble a petition must make sure the form in the packet is the 02/27/26 edition.

A mismatch could cost time at the start of a filing season when timing already matters. Rejection forces a petitioning employer to correct the form and refile, adding delay to a process that often runs on fixed windows and internal hiring schedules.

USCIS has not tied the form change to every work authorization filing in its system. The change is limited to I-129 petitions, a distinction that matters for companies handling several immigration processes at once.

Even so, I-129 is widely used across business immigration. U.S. employers rely on it to petition for workers in temporary classifications ranging from seasonal labor programs to intracompany transfers and specialty occupations.

Because the same form supports many visa types, the edition-date check becomes a basic compliance step for legal teams, human resources staff, and outside preparers. The rule is simple, but the consequence is immediate rejection if a filing mailed on or after April 1 carries the old version.

The revision also signals what USCIS wants to see in H-1B cases this year: a fuller picture of the job itself. Minimum educational qualifications, the exact field of study, required experience, and supervisory duties all speak to how the agency will evaluate the offered role against the wage level selected.

That focus links the petition more tightly to the underlying Labor Condition Application. By capturing the LCA wage level and the wage level selected during H-1B registration, USCIS is building a clearer comparison point inside the form.

For employers, that means consistency across documents is likely to matter more. Inconsistencies may trigger RFEs or denials, making careful review of the registration, the LCA, and the petition especially important for FY2027 H-1B filings.

Nothing in the update changes the filing rule for other USCIS forms. Nothing in it expands beyond I-129 petitions, even though it refers broadly to work visa filings.

That narrower scope leaves employers with a defined task. They must confirm that every Form I-129 mailed on or after April 1, 2026, uses the 02/27/26 edition, and they must complete the added job-detail fields that USCIS now requires.

For companies entering the FY2027 H-1B process, the first day of filing and the first day of rejection risk now arrive together. On April 1, 2026, the wrong edition of Form I-129 will not move forward.
