The Department of Homeland Security’s (DHS) heightened scrutiny of applications for benefits and employment eligibility compliance documents continues.

In an interim final rule (IFR) published May 11, 2026, DHS amended U.S. Citizenship and Immigration Services (USCIS) regulations to tighten enforcement of signature requirements on immigration benefit requests, a change that could increase risk for applicants, petitioners, and employers. The rule takes effect July 10, 2026, with comments accepted through the same date. This shift reduces the margin of error for filers who previously assumed that acceptance of a benefit application at intake meant that it a filing met all threshold requirements.

While immigration forms have long required valid signatures, this IFR formalizes USCIS’s authority to act on signature deficiencies discovered later in the adjudication process. It clarifies that USCIS may reject or deny a benefit request if it later determines the filing lacks a valid signature—even if the request was initially accepted for processing. The distinction between “reject” and “deny” matters as denials carry more serious consequences than rejections. A rejection generally results in a returned filing fee and allows refiling, though without preserving the original filing date. A denial, by contrast, may result in loss of the filing fee and a final adverse decision on the request.

Both individual applicants and employer petitioners are affected. Filings that involve multiple signatories or corporate signatures may face elevated risk if authority or execution is unclear.

The rule applies broadly to all USCIS benefit requests, including but not limited to:

• Employment‑based petitions

• Applications for work authorization

• Adjustment of status applications

• Naturalization and citizenship filings

While USCIS retains discretion to request clarification or additional evidence, the IFR makes clear that rejection or denial is now an available option. As a result, applicants and employers may want to:

• Confirm signature requirements for each form before filing

• Verify signing authority for employer‑sponsored submissions

• Ensure consistency across paper and electronic filings

• Monitor cases closely even after receipt notices are issued

The rule underscores a growing emphasis on procedural precision in immigration filings, where small errors that were correctable in the past may now carry outsized consequences.

This March 11 move follows the Immigration and Customs Enforcement (ICE) updated of its long‑standing Form I‑9 Inspection Fact Sheet, narrowing the category of errors that employers are allowed to correct after an audit begins and expanding the list of issues that can trigger immediate fines, which we decipher for members here.
