H-1B, L-1 and other I-129 extensions: USCIS proposes to delete the deference rule at 8 CFR 214.1(c)(5)

Last updated 2026-10-19 · General information, not legal advice

On 14 October 2026 the Department of Homeland Security published a proposed rule to delete 8 CFR 214.1(c)(5), the regulation that tells USCIS officers to follow their own earlier approval when an employer files an I-129 extension on the same facts for the same worker. Nothing has changed yet: the rule is a proposal, comments close on 13 November 2026, and extensions filed today are still adjudicated under the deference regulation. The numbers that matter to anyone already waiting come from USCIS itself. It estimates the change would raise the request-for-evidence rate by 2.9 percentage points, about 6,044 more RFEs a year, and it reports that across fiscal years 2022 through 2025 an I-129 that drew an RFE took a median of 76 days against 12 days for one that did not. The proposal's own words for the effect are "lengthening adjudication times."

What was published

The document is a notice of proposed rulemaking, not a final rule. It appears at 91 FR 65119 and the full text is on govinfo. Its identifiers are RIN 1615-AD26, DHS Docket No. USCIS-2026-0529 and CIS No. 2870-26. The regulatory text at the end of the proposal does one thing: it removes and reserves paragraph (c)(5) of 8 CFR 214.1 and leaves the rest of the section alone.

The provision reads today: "When adjudicating a request filed on Form I-129 involving the same parties and the same underlying facts, USCIS gives deference to its prior determination of the petitioner's, applicant's, or beneficiary's eligibility. However, USCIS need not give deference to a prior approval if: there was a material error involved with a prior approval; there has been a material change in circumstances or eligibility requirements; or there is new, material information that adversely impacts the petitioner's, applicant's, or beneficiary's eligibility." (8 CFR 214.1(c)(5), 2025 CFR)

Two limits in that text are worth holding onto, because they describe the rule as it stands rather than the rule as either side characterises it. Deference applies only where the parties and the underlying facts are the same, and it already yields to a material error, a material change, or new adverse material information. What the proposal removes is the instruction to follow the prior determination when none of those three exceptions is present.

The scope is narrow in one direction and wide in another. It reaches only requests filed on Form I-129, so an I-485, an N-400 or an I-130 is untouched. Within I-129 it reaches the extension boxes, which is most of the nonimmigrant worker population: H, L, O, P, R, TN and E filings all travel on that form.

Comments go through regulations.gov under docket USCIS-2026-0529 and nowhere else. The proposal states that comments sent any other way, including emails or letters to DHS or USCIS officials, will not be treated as comments on the rule and may get no response, and that hand-delivered, couriered and digital-media submissions are not accepted. Everything submitted is posted publicly with whatever personal information it contains.

The fourth reversal since 2004

The proposal sets out its own history, with dates:

• 23 April 2004. USCIS memorandum HQPRD 72/11.3 first instructed officers to defer to a prior determination of eligibility on an extension involving the same parties and the same facts, absent material error, substantially changed circumstances or new material information.
• 23 October 2017. Memorandum PM-602-0151 rescinded the 2004 guidance, on the stated grounds that deference shifted the burden of proof off the petitioner and unduly restricted officers' fact-finding authority.
• April 2021. USCIS reinstated deference and wrote it into the Policy Manual at Volume 2, Part A, Chapter 4.
• 18 December 2024. DHS codified it as a regulation at 8 CFR 214.1(c)(5) through the H-1B modernization final rule, 89 FR 103054.

So deference was in force from April 2004 to October 2017 and again from April 2021 to now. The three-and-a-half year gap in between is where USCIS found the data for its estimate.

What USCIS estimates it would cost in time

The economic analysis is the most useful part of the document, because it is the agency measuring its own adjudications rather than predicting them.

How many filings are in scope. Across fiscal years 2022 through 2025 an average of 208,429 I-129 petitions a year were eligible for deference, 30 percent of all I-129 filings; in FY 2025 it was 235,583 of 714,810. Eligible filings are identified by box b or c at Part 2, Question 2 of the form. The source is the USCIS Chief Data and Analytics Office, CLAIMS3 and ELIS, queried May 2026. The proposal notes the count may be slightly low, because some amendment filings that also get deference cannot be separated out reliably.

How many more RFEs. USCIS ran a difference-in-differences comparison across the two periods. For the filings deference reaches, the RFE rate was 18.9 percent while deference applied (1 October 2013 to 11 October 2017) and 23.4 percent while it did not (12 October 2017 to 27 April 2021), a rise of 4.5 points. A comparison group that deference never reached rose 1.6 points over the same span, from 31.4 to 33.0 percent. Subtracting leaves 2.9 percentage points attributable to the policy, which applied to 208,429 filings yields roughly 6,044 additional RFEs a year.

Denials, by contrast. USCIS applied the same method to denial rates and reports that it found no corresponding change. The proposal's conclusion is that "this analysis does not indicate an expected impact on denial rates." On the agency's own evidence, the change is about how often it asks for more, not how often it says no.

How much longer the wait. Footnote 27 carries the figure that matters most to a pending case. For fiscal years 2022 through 2025, the average of the median processing times was 76 days for I-129 petitions with an RFE and 12 days for those without, a difference of 64 days, measured from the receipt date to the initial decision. The proposal uses that 64 days as the additional processing time an RFE brings, and says petitioners "may experience longer adjudication times and increased uncertainty regarding continued employment."

What it counts as a cost. Only the employer-side time to prepare RFE responses is quantified: about $133,987 a year, $1,339,870 undiscounted over ten years. USCIS's own added adjudication workload is acknowledged and left unquantified. The Office of Management and Budget did not designate the proposal a significant regulatory action under Executive Order 12866 and did not review it.

What this means for a delay case

Start with what does not move. Our filing threshold for a stalled I-129 is unchanged — see H-1B or L-1 petition stuck: who sues USCIS, and where. A mandamus suit asks a court to order a decision; it cannot ask for an approval, and that is true whatever happens to this rule. A proposed rule also changes nothing about a petition pending today.

Three things do change, and the first is the one to calendar.

An extra RFE eats into the 240 days. Under 8 CFR 274a.12(b)(20), a worker whose status has expired but whose extension was timely filed is "authorized to continue employment with the same employer for a period not to exceed 240 days beginning on the date of the expiration of the authorized period of stay." That window runs from the expiry of the authorized stay, not from the date an RFE is issued, and the same provision terminates the authorization on notice if USCIS denies the extension inside the 240 days. Measure USCIS's own 64 days against that ceiling: one RFE consumes more than a quarter of it. The classifications the provision lists include H-1, H-2A, H-2B, H-3, L-1, O-1, O-2, P, R, TN and E-3; check the text for your own.

Premium processing resets rather than protects. On the USCIS premium processing page (last reviewed 23 March 2026), most I-129 classifications carry a 15 business day commitment, and issuing an RFE is itself one of the actions that satisfies it. The page states that when evidence is requested "the 15-, 30-, or 45-day premium processing time period will stop and reset," and that "a new premium processing time period will begin when we receive a response." A higher RFE rate therefore means more resets on the one paid route that exists. It is also worth knowing that premium processing and the free expedite request are mutually exclusive — the five expedite criteria explain which forms fall on which side.

Attributing the wait gets harder to argue. Courts assess delay through the TRAC factors, and the first two look for a rule of reason and for any timetable Congress supplied. An RFE moves a block of the calendar onto the applicant's side of the ledger: the notice arrives, the employer gathers documents, the response goes in. Our page on whether an RFE resets your USCIS wait works through what that does to the clock. More RFEs on extension filings means that question comes up more often. That reading is ours, not the agency's — the proposal counts days and dollars and says nothing about litigation.

Two things this page will not do. It will not predict whether the rule is finalised, in what form, or when: a proposal has to pass through a comment period and a final rule, and this one carries no statutory deadline. And it will not tell any particular case whether to sue.

What to do

1. Write down two dates, not one. The Received Date on the I-797C receipt notice, which is where a delay threshold starts, and the expiry of the authorized stay on the I-94, which is where the 240 days start. The 60-second self-check runs the first one for you.
2. Treat an RFE on an extension as same-day work. The notice carries its own deadline, and an earlier response is an earlier restart. Keep the response and proof of delivery with their dates; they are the record that shows whose time the calendar belongs to.
3. Check whether your classification is on the premium list. If it is, the petitioner can add Form I-907 to a petition already pending. A missed commitment brings the fee back, and a refund is not a decision; the petition is still with USCIS.
4. Run the free channels in parallel. A case inquiry and a congressional inquiry cost nothing, and neither is a precondition to filing suit.
5. Comment by 13 November 2026 if you want to be heard on the rule. File on regulations.gov under docket USCIS-2026-0529. The proposal says the comments that help most cite a specific portion of the rule, explain the reason for the change and bring data or authority. Submissions are published as filed, so leave out what you do not want public.
6. Compare your wait with the published figure before concluding anything. USCIS posts processing times by form and office; our processing-times page explains the basis and the line at which a case inquiry opens.

If you are not sure whether your wait is long enough to qualify, run the 60-second self-check against your receipt date. For what makes a case worth a closer look, see when to sue USCIS.
