USCIS Invalid Signature Rule: H-1B and EB Denials Start July 10

On May 11, 2026, the Department of Homeland Security published an interim final rule, [Signatures on Immigration Benefit Requests](https://www.federalregister.gov/documents/2026/05/11/2026-09289/signatures-on-immigration-benefit-requests) (91 FR 25479; Docket No. USCIS-2026-0166; RIN 1615-AD17), amending 8 CFR 103.2(a)(7)(ii)(A). The rule expressly authorizes USCIS to deny - not just reject - a benefit request when, after acceptance, the agency determines the filing lacks a valid signature.

Today is May 12, 2026. The rule takes effect on July 10, 2026 and applies to requests submitted on or after that date. The 60-day public comment period closes the same day, leaving 59 days for employers, sponsored workers, and counsel to weigh in before the agency finalizes the framework.

1. What the rule actually changes

Until now, signature defects were managed largely through USCIS policy memoranda and form instructions. If a problem was caught at intake, USCIS rejected the filing and returned the fee. If a problem was caught later, the agency's authority to do more than ask for evidence was ambiguous.

The interim final rule revises 8 CFR 103.2(a)(7)(ii)(A) to provide that every form, benefit request, or other document that requires a signature must be submitted with a valid signature, and that if USCIS accepts a benefit request and determines later that it was not submitted with a valid signature, USCIS may, in its discretion, reject or deny the request.

• Effective date: July 10, 2026.
• Applies to: requests submitted on or after July 10, 2026.
• Comment deadline: July 10, 2026, at [Regulations.gov, Docket No. USCIS-2026-0166](https://www.regulations.gov/docket/USCIS-2026-0166).
• DHS issued the rule as an interim final rule with concurrent comment, invoking the Administrative Procedure Act good-cause exception.

2. What invalid signatures look like, per USCIS

The preamble uses concrete examples. USCIS will treat a signature as invalid where it is a photocopy, fax, or scan that is not a reproduction of a document carrying an original handwritten signature; where it is a software-generated, stamped, or autopen signature outside the USCIS online filing system that is not expressly permitted by the form instructions; or where it is executed by someone other than the applicant or petitioner without proper authorization.

• An authorized signatory who signed a blank sheet of paper and had a subordinate copy that signature onto at least 20 Petitions for Nonimmigrant Worker (Form I-129).
• A consulting firm that completed and filed approximately 3,000 Petitions for Immigrant Worker (Form I-140) using a copied signature.
• Use of an image of a signature pasted from one signed document onto multiple otherwise unsigned filings.

3. Rejection versus denial: why the distinction matters

Under prior practice, the realistic worst case for a signature problem was rejection: USCIS returned the filing and the fee, and the petitioner refiled. Under the interim final rule, USCIS may instead deny the case after acceptance. The legal and practical consequences are different.

A denial is a final adjudicative action. USCIS may retain the associated benefit filing fee and treat the applicant as ineligible for the requested benefit. There is no opportunity to cure the signature defect after submission; the rule confirms that an invalid signature renders the request improperly completed at the time of filing.

• I-140 petitions: a denial extinguishes the priority date associated with that filing. The beneficiary loses their place in line, and any AC21 portability tied to the I-140 approval is lost.
• I-129 H-1B, L-1, and O-1 petitions: a denial can leave the beneficiary out of valid status, with no automatic extension to refile, and potentially trigger unlawful presence if the I-94 expires in the interim.
• Premium processing: a denial counts as an adjudicative action, so the [premium processing fee of $2,965 for I-129](https://www.uscis.gov/newsroom/alerts/uscis-to-increase-premium-processing-fees) and the increased I-140 premium fee, both effective March 1, 2026, are consumed even if the underlying petition is denied on signature grounds.
• Appeals: a denial may be challenged through Form I-290B (notice of appeal or motion), but the AAO record already shows hundreds of appeals on signature-only denials, most of them unsuccessful.

4. Scope: which filings are reached

Because 8 CFR 103.2 governs the submission of benefit requests generally, the rule reaches the full range of employment-based filings where a signature is required, including:

• Form I-129 petitions across H-1B specialty occupation, H-1B1, E-3, L-1A and L-1B intracompany transferees, O-1 extraordinary ability, and TN cases.
• Form I-140 immigrant petitions across EB-1A, EB-1B, EB-1C, EB-2, EB-2 National Interest Waiver, and EB-3 (including Schedule A) categories.
• Form I-290B notices of appeal or motion filed against denials in any of the above.
• Form I-693 medical exams, Form I-918 U petitions, and other employment-adjacent or humanitarian filings.

5. What attorneys should know

Three implementation details from the preamble warrant attention now.

First, the rule provides no notice-and-cure mechanism. The agency states that filings are deemed improperly completed at the time of filing if not validly signed, and that signature problems are not curable post-submission. A Notice of Intent to Deny is not required before USCIS denies on signature grounds.

Second, the rule is procedurally an interim final rule with concurrent comment, not a notice-of-proposed-rulemaking. DHS invokes the APA good-cause exception and characterizes the change as procedural and clarifying. That posture makes a pure APA process challenge harder than it would be against a substantive rule, but substantive challenges to the scope of authority claimed under 8 CFR 103.2 remain available.

Third, the carve-out for N-600 and N-600K is keyed to the unique refiling restrictions in 8 CFR 320.5(c), 322.5(c), and 341.5(e). Comparable refiling limits do not apply to employment-based petitions, which is the doctrinal reason USCIS treats I-129 and I-140 filings as denial-eligible under the rule.

6. What employers and applicants should do before July 10

The effective date is 59 days away. Practical steps that can be taken now:

• Audit signatory protocols. Identify every authorized signatory on I-129 and I-140 filings, confirm each is current, and require that each petition be signed contemporaneously in original ink on the executed petition - not on a separate signature page later attached.
• Eliminate stockpile signatures. Pre-signed blank forms, image-stamped signatures, and software e-signatures applied outside the USCIS online account should be removed from intake workflows immediately. The preamble flags these as exemplars of invalid signatures.
• Retain wet-ink originals. The petition copy bearing the original handwritten signature should be retained for the duration of the case and any subsequent appeal window in case USCIS questions signature integrity post-acceptance.
• Document chain of custody. For I-129 and I-140 filings between now and July 10, document the signatory chain of custody so that filings already in transit can be defended if signature issues are raised mid-adjudication.
• File a comment if the rule will materially affect your filings. Comments are accepted at [Regulations.gov, Docket No. USCIS-2026-0166](https://www.regulations.gov/docket/USCIS-2026-0166) through July 10, 2026.

7. Wider policy context

This rule lands alongside a cluster of other employment-based changes already in motion: the [DHS weighted H-1B cap selection rule](https://www.federalregister.gov/documents/2025/12/29/2025-23853/weighted-selection-process-for-registrants-and-petitioners-seeking-to-file-cap-subject-h-1b) effective February 27, 2026; the [USCIS premium processing fee increase](https://www.federalregister.gov/documents/2026/01/12/2026-00321/adjustment-to-premium-processing-fees) effective March 1, 2026; and the DOL prevailing wage NPRM whose [comment period closes May 26, 2026](/blog/dol-h1b-perm-wage-rule-2026-comment-period).

Read together, the trend is structural. USCIS is tightening adjudicative gates at every stage of the H-1B and EB pipeline, and the signature rule moves a previously curable defect into a fully terminal one. Employers running high-volume I-129 and I-140 programs should treat the next 59 days as a compliance window, not a planning horizon.
