Status as of October 13, 2026. DHS has filed a proposed rule that would remove the regulation requiring USCIS officers generally to defer to a prior eligibility determination when reviewing certain Form I-129 extension requests involving the same parties and underlying facts. The proposal is scheduled for Federal Register publication on October 14 and is not yet in effect. The existing deference rule remains controlling while the rulemaking is pending.
The Department of Homeland Security is proposing to eliminate a rule that generally tells U.S. Citizenship and Immigration Services officers to respect a prior approval when the same employer and worker seek an extension on materially unchanged facts.
The notice of proposed rulemaking would delete 8 CFR 214.1(c)(5). That provision currently directs officers adjudicating a Form I-129 extension to defer to the earlier eligibility determination unless the record shows a material error, a material change in circumstances or new material information that adversely affects eligibility.
The change would not automatically cancel any existing petition approval. Nor would it decide a pending extension by itself. If finalized, however, it would give officers wider room to examine every eligibility element again and could produce more requests for evidence, longer adjudications and less predictability for employers and workers.
What the current rule does
The current regulation applies when USCIS reviews a Form I-129 request involving the same parties and the same underlying facts as an earlier approval. The petitioner still carries the burden of proof and must submit the evidence required for the new filing. Deference is not an automatic approval: USCIS may depart from the earlier decision if it identifies a material error, changed circumstances or adverse new information.
The policy has moved back and forth for more than two decades. USCIS introduced deference guidance in 2004, rescinded it in 2017, restored it through policy guidance in 2021 and codified it in the H-1B modernization final rule published in December 2024. The new proposal would remove the codified provision rather than replace it with a narrower deference standard.
Which cases could be affected
The proposal concerns extensions filed on Form I-129, the petition used across many temporary worker classifications. DHS identifies extensions involving E-1, E-2, E-3, H-1B, H-1B1, H-2A, H-2B, H-3, L-1, O-1, O-2, P-1, P-2, P-3, Q-1, R-1 and TN classifications among the filings within the Form I-129 framework.
For an employer and employee with an unchanged job, ownership structure and underlying facts, a past approval would no longer trigger a regulatory presumption favoring consistency. USCIS could conduct a fresh review of issues already considered in the earlier case. Petitioners would need to organize the extension record so that it independently demonstrates present eligibility instead of assuming the prior approval will carry the same issue.
The proposal does not change the separate rules that determine how long a nonimmigrant may remain or work while a timely extension is pending. It changes how USCIS evaluates eligibility for the requested extension.
Why DHS says it wants the change
DHS says deference can constrain officer fact-finding and create a risk that an erroneous earlier approval will be repeated. It argues that removing the provision would reinforce the statutory burden on the petitioner and allow a complete, current review of every case.
The notice cites targeted and administrative site-visit data for H-1B and L-1A extensions. DHS reports higher combined rates of fraud or noncompliance among visited sites during fiscal years when deference was in effect than during an earlier period without it. The agency also acknowledges that other factors may have contributed, so those figures do not establish that deference caused the difference.
Expected practical effects
DHS estimates that roughly 30 percent of Form I-129 petitions were potentially eligible for deference in recent years. It projects about 6,044 additional requests for evidence annually if the proposal becomes final. The agency estimates $133,987 in aggregate annual petitioner time costs for responding to those additional requests, while recognizing unquantified costs from extra preparation, uncertainty and potential operational disruption.
The proposal notes that cases receiving a request for evidence took an average of 64 additional calendar days to process in fiscal years 2022 through 2025. That does not mean every extension would be delayed by 64 days. It is an agency average for cases with an RFE and illustrates the potential consequence of more intensive review.
Because this is a proposal, employers should not treat it as a new filing rule today. The operative requirements are the regulation, form instructions and policy guidance in effect when a case is filed and adjudicated. A later final rule could differ from the proposal and would specify its own effective date.
How to comment
The public-inspection version is scheduled for publication on October 14, 2026. It provides a 30-day comment period, so comments are due by November 13, 2026. Comments must be submitted through Regulations.gov under DHS Docket No. USCIS-2026-0529. Submissions are generally posted publicly, including personal information provided by the commenter.
Frequently asked questions
Has USCIS already stopped giving deference to prior I-129 approvals?
No. DHS filed a proposed rule on October 13, 2026. The current regulation remains in place unless and until DHS publishes a final rule with an effective date.
Which filings would the proposal affect?
The proposal targets Form I-129 requests to extend nonimmigrant employment or stay involving the same parties and underlying facts. The rule discusses classifications that use Form I-129, including H-1B, L, O, P, R, TN and several E and H categories.
Would a prior approval become irrelevant?
Not necessarily. The proposal would remove the regulatory instruction to defer, but prior decisions would remain part of the record. Petitioners would need to establish current eligibility with the evidence submitted for the extension.
When are comments due?
The public-inspection document is scheduled for publication on October 14, 2026. It sets a 30-day comment period, making comments due November 13, 2026, through Regulations.gov under docket USCIS-2026-0529.
