Starting July 10, 2026, US Citizenship and Immigration Services (USCIS) has the explicit authority to deny — not just reject — an immigration filing if it later determines the signature on it was invalid, even if the case was already accepted and the filing fee already banked. The change comes from an interim final rule published by the Department of Homeland Security in the Federal Register on May 11, 2026, amending the regulation at 8 CFR 103.2(a)(7). The distinction matters: a rejected filing is simply returned, with no fee kept and no filing date recorded, so the applicant can fix the problem and refile. A denied filing is treated as fully adjudicated — USCIS keeps the fee, and the applicant is found ineligible for the benefit at that time. The rule applies broadly, covering the signature requirement across nearly every USCIS form, from family-based green card petitions to naturalization applications to employment-based worker petitions.
Background
USCIS has long required a "valid signature" on benefit requests — under current regulations, generally a handwritten mark, or in limited cases a secure electronic signature captured during guided e-filing or the agency's PDF upload process. Since 2018, USCIS sub-regulatory policy already stated that if the agency accepted a request and later found the signature deficient, it would deny the request. But DHS says in the rule's own text that application of that policy "has not resulted in benefit requestors having a clear understanding" of how USCIS handles questionable signatures, and that USCIS officers themselves "have not always understood the scope of their authority" when signatures were in question. DHS says it has seen "several instances of questionable and invalid signatures" in recent years and inconsistent handling of them across the agency. This rule is meant to close that gap by codifying, in the regulation itself rather than internal guidance, that USCIS adjudicators may exercise discretion to deny — and keep the fee — when a signature does not hold up.
What exactly changed
The rule amends 8 CFR 103.2(a)(7) so that USCIS may, at its discretion, either reject a request for an invalid signature (the existing practice, with no fee kept and no filing date recorded) or deny it after review (the newly codified option, where USCIS keeps the fee and treats the case as fully adjudicated). There is no cure mechanism: the rule confirms that a valid signature is a threshold filing requirement, and USCIS does not offer an opportunity to fix a deficient signature after the fact. On what counts as valid, the rule is specific. Acceptable signatures are a handwritten mark made in pen, a scanned, photocopied, or faxed copy of an original handwritten signature, or — only where the specific form's instructions permit it — a secure electronic signature captured during guided online e-filing or the PDF upload process. Not acceptable: a typed name standing in for a signature, output from signature-generation software, an auto-pen signature, or a signature from someone other than the requestor, except in limited cases such as a parent or legal guardian signing for a minor, or someone signing on behalf of a person unable to sign for themselves.
Reject vs. deny, before and after this rule
- Rejected filing: no fee retained, no filing/receipt date recorded, applicant can correct the problem and resubmit.
- Denied filing (this rule's codified option): USCIS retains the filing fee, treats the case as fully adjudicated, and the applicant is found ineligible for the benefit — no correction opportunity.
- Since 2018 (informal policy): denial for deficient signatures was already directed in some cases, but applied inconsistently across the agency.
- From July 10, 2026: the reject-or-deny discretion is written directly into the regulation itself.
Who it affects
This applies to nearly anyone filing a USCIS benefit request on or after July 10, 2026 — someone filing an I-130 family petition, an I-485 adjustment-of-status application, an N-400 naturalization application, an I-90 green card renewal, an I-765 work-permit application, or an I-129 nonimmigrant worker petition such as an H-1B. It is especially relevant for anyone using an attorney or preparer: the requestor, not the attorney, generally must be the one who signs, and there is currently no electronic-signature option for attorney-filed PDF uploads. A single missed or improper signature on an otherwise complete, fee-paid application can now result in the case being closed as denied rather than simply bounced back for a fix.
What this means in practice
Anyone filing with USCIS on or after July 10, 2026 should sign in pen wherever a paper or scanned filing is used, and check that specific form's instructions for whether an electronic signature is permitted at all. Because there is no cure period once a request is denied for a signature defect, confirming the signature is correct before mailing or submitting online is now a higher-stakes step than it used to be. Anyone weighing a move to the US on a work or family visa can find broader context on the process in GoMate's United States country guide at /country-guides/united-states.
When it takes effect
The rule took legal effect July 10, 2026, the same date this article is published. It applies to benefit requests submitted on or after that date.
What is not yet confirmed
This is an interim final rule, meaning it is already in force, but the public comment period on it remains open only through July 10, 2026 — the same day the rule takes effect — per the Federal Register's own DATES section. DHS could still revise the rule based on comments received. No verified statistics on how often signature-defect denials have occurred were found in the sources reviewed for this article, so none are cited here.
Key Takeaway
From July 10, 2026, a bad signature on a USCIS filing can mean an outright denial with the fee kept, not just a returned form you can fix and resubmit — check your form's specific signature instructions before you file.
