USCIS's Deference Proposal Isn't Just About H-1B: What It Would Mean for O-1, L-1, TN and E-3 Extensions
The deference proposal reaches every I-129 extension. O-1 and L-1 petitions drew RFEs about three times as often as H-1B in FY2026 Q1-Q3, so those workers have the most at stake.
Part of our guide to the O-1 visa.
Status as of 2026-11-01: USCIS deference to prior approvals is in effect. The rule at 8 CFR 214.1(c)(5) tells USCIS to defer to its earlier Form I-129 approval when an extension involves the same parties and the same facts. A DHS proposal published 2026-10-14, "Removing Deference to Prior USCIS Determinations of Eligibility" (RIN 1615-AD26), would delete that rule for every I-129 extension class, not just H-1B, so O-1, L-1, TN and E-3 are all covered. It is proposed, not final, and comments close 2026-11-13.
It likely matters more to O-1 and L-1 workers than to most H-1B workers (our reading). In USCIS's FY2026 Q1-Q3 data, O and L-1 petitions drew RFEs in 24.2% to 29.4% of decisions, against 8.5% for H-1B, roughly three times as often (our arithmetic).
- In effect: 8 CFR 214.1(c)(5) and the deference guidance in the USCIS Policy Manual.
- Proposed: the deference-removal NPRM (91 FR 65119, docket USCIS-2026-0529), with about 400 public comments as of 2026-11-01.
- Scheduled: from 2026-11-09, USCIS accepts only the 09/09/26 edition of Form I-129.
What is USCIS deference to prior approvals?
USCIS deference to prior approvals means that when your employer files a Form I-129 extension with the same petitioner, the same beneficiary and the same underlying facts, the officer starts from USCIS's earlier approval instead of re-deciding eligibility from scratch. Under 8 CFR 214.1(c)(5), officers can still decline to defer for a material error, a material change, or new adverse information.
The USCIS Policy Manual chapter on extensions adds that "any deviation requires close consideration of the previous approval by USCIS." An officer who does not defer must acknowledge the earlier approval, explain why, let the petitioner respond, and get supervisory approval before departing from it in a final decision. DHS calls those steps evidence that deference relaxes the petitioner's burden, and says USCIS would make "corresponding changes" to the guidance if the rule is finalized.
Deference has two built-in limits. It covers only USCIS's own decisions: the Policy Manual says officers "consider, but do not defer to," eligibility decisions made by CBP or the State Department. And a first petition or a new employer has no earlier approval for the same parties.
The policy has flipped before. According to the NPRM, USCIS set out deference in an April 2004 memo, rescinded it in October 2017, reinstated it in April 2021 and codified it in December 2024 (89 FR 103054). Deference never shifted the burden of proof, as the proposal on govinfo.gov puts it: "Even if the prior approval was not erroneous, the burden of proof remains on the petitioner to establish eligibility in each benefit request."
Does the deference rule apply to O-1 and L-1 extensions?
Yes. The proposal "would apply to all benefit requests filed using Form I-129, Petition for a Nonimmigrant Worker," and its list of extension classes includes E-1, E-2, E-3, H-1B, H-1B1, H-2A, H-2B, H-3, L-1, O-1, O-2, the P classes, Q-1, R-1 and TN. It would not stop officers from looking at your history: "This proposal would not prohibit USCIS officers from considering a prior approval where relevant." Instead, "it would remove the requirement that officers begin from a position of deference to the prior approval."
Which extension filings would actually feel it?
DHS counted as affected the petitions that check box b (continuation of previously approved employment without change with the same employer) or box c (change in previously approved employment) in Part 2 of Form I-129, against a comparison group of new employment, new concurrent employment and change of employer. It left amended petitions (box f) out, though USCIS may apply deference to some.
So the people exposed are those extending with the same employer, in the same role, on the same facts, after an earlier USCIS approval (our reading). Little would change on the next filing for:
- A first O-1, TN or E-3 petition, or a move to a new employer (no prior approval to defer to).
- A TN worker first admitted by CBP at the border, or an E-3 worker whose status came from a consular visa (USCIS already does not defer to those decisions).
- A blanket L-1 worker whose individual eligibility was decided at a consulate or port of entry, for the same reason.
Why O-1 and L-1 have more at stake than H-1B
The classes with the highest RFE rates and the most judgment-heavy standards give an officer the most to re-ask.
Deference and your extension, by class (as of 2026-11)
| Class | FY2026 Q1-Q3 approval / RFE rate | What a prior USCIS approval usually settles (our reading) | What an officer could ask again without deference (our reading) | Extension terms |
|---|---|---|---|---|
| O-1 | 91.0% / 24.2% (all O petitions) | Extraordinary ability or achievement | Evidence against the O criteria; the event or activity for the new period | Increments of up to one year to "continue or complete the same event or activity" |
| L-1A | 91.2% / 25.9% | Qualifying relationship; one continuous year abroad; managerial or executive capacity | Ownership or affiliation records, organization charts, who or what you manage, your actual duties | Up to two years at a time; seven-year maximum; a new-office L-1A starts at one year |
| L-1B | 91.3% / 29.4% | Specialized knowledge | How your knowledge of the company's products, processes or procedures is special or advanced | Up to two years at a time; five-year maximum |
| TN | 94.9% / 13.0% (USCIS-filed only) | The role fits a USMCA profession; your qualifications | A job description matching the listed profession, your degree or license, prearranged employment | Up to three years per extension; "no specific limit on the total period" (8 CFR 214.6) |
| E-3 | No E-3 table in the USCIS file | Specialty occupation; your degree | Proof the role needs a specialty degree, your degree, a certified LCA for the new period | Up to two years per extension; no maximum number, "with some exceptions" |
| H-1B (comparison) | 97.0% / 8.5% | Specialty occupation; your degree | The same questions, documented again | See our H-1B deference guide |
Rates are approvals divided by approvals plus denials, from the USCIS I-129 RFE data for FY2026 Q1-Q3. They mix initial petitions and extensions, cover October 2025 to June 2026, exclude blanket L filings, and predate PA-2026-05 (in effect since 2026-08-05, challenged in AAUP v. Mullin), which lets officers deny without an RFE or NOID when required initial evidence is missing. More in our O-1, L-1 and TN approval and RFE rates breakdown. Extension terms come from the USCIS pages for O-1, L-1A, L-1B, TN and E-3.
O-1: the "settled" questions are the hardest ones
An O-1 approval rests on judgment calls about whether your record meets the criteria. Today, to continue or complete the same event or activity, the employer or agent files the I-129, a copy of your I-94 and a statement explaining the reasons for the extension, per USCIS's O-1 page. The proposal leaves that list alone; it only removes and reserves 8 CFR 214.1(c)(5). Without that paragraph, though, an officer could ask again whether you meet the criteria (our reading). Our complete O-1 visa guide covers the criteria and the advisory opinion.
L-1A and L-1B: DHS's own example
DHS cites site-visit data for only H-1B and L-1A. It reports non-compliance or fraud at 24.46% of L-1A extension sites visited in FY2022-FY2025, with deference, against 18.37% in FY2018-FY2020, without it, and concedes "other factors besides or in addition to deference" may explain the gap. L-1B had the highest RFE rate in the table, and whether knowledge is "specialized" is the kind of judgment deference now usually leaves alone (our reading). The L-1 intracompany transfer guide explains the one-year-abroad rule and both tests.
TN and E-3: lower RFE rates, often no USCIS approval to defer to
The USCIS TN page describes two routes: your employer files an I-129, or you depart before your status expires and apply again at a CBP-designated port of entry or pre-clearance station with the same documents as the first time. CBP decides the second route, and 8 CFR 214.1(c)(5) governs USCIS decisions on Form I-129, so the proposal does not speak to it (our reading). Which route fits is a question for your employer's attorney.
For E-3, the core question mirrors H-1B (specialty occupation plus your degree), and each extension needs a certified LCA. If your E-3 status came from a consular visa, your first USCIS extension already gets no deference. Our E-3 visa guide for Australians covers the basics.
How many extra RFEs does DHS expect?
DHS estimates about 6,044 additional RFEs a year across 208,429 affected I-129 petitions (its FY2022-2025 average), from a 2.9 percentage point rise in the RFE rate, at about $133,987 a year in added cost to petitioners. DHS did not split it by class.
- It is an average across every I-129 class. DHS's difference-in-differences model compares the two groups overall. Nothing says the rise would be equal for O-1, L-1B and TN.
- The cost assumes a small time burden. DHS uses "the estimated time burden of 10 minutes (0.167 hours)," or $22.17 per additional RFE in its own table. If that does not match an RFE response in your class, the comment period is the place to say so.
- An RFE is not the only outcome. Under PA-2026-05, an officer may deny without an RFE or NOID when required initial evidence is missing, whatever happens to deference.
Is the deference rule final?
No. As of 2026-11-01, the removal of deference is a proposed rule, and the current regulation applies to every extension USCIS decides. Only a final rule in the Federal Register could change that, and it would set its own effective date. The proposal gives no date for a final rule.
Dates that matter (as of 2026-11)
| Date | What happens | Status |
|---|---|---|
| 2026-10-14 | Deference NPRM published (91 FR 65119) | Proposed |
| 2026-11-09 | Only the 09/09/26 I-129 edition accepted; old filing addresses accepted only if postmarked on or before this date | Scheduled |
| 2026-11-10 | Comments close on the worker 60-day grace-period proposal | Proposed |
| 2026-11-13 | Comments close on the deference proposal (check the docket / Federal Register for the outcome after 2026-11-13) | Proposed |
| No date | DHS reviews comments; it may finalize, revise or not act | Unknown |
A worked example
Say you are on L-1B after a USCIS approval, your I-94 runs to 2027-04-30, and your employer's attorney plans a same-role extension in January 2027.
- While no final rule is in effect, 8 CFR 214.1(c)(5) governs, and the officer starts from the earlier approval unless an exception applies.
- If a final rule is published first, its effective date and applicability text decide whether pending or new petitions are covered. Ask counsel at that point.
- Either way, the petition goes on the 09/09/26 I-129 edition, and a covered employer pays the $4,500 9-11 fee (L-1 petitions postmarked 2026-09-09 through 2027-09-30).
The USCIS processing times tool showed 6.5 months for L petitions, 14.5 for O and 4.5 for TN on 2026-11-01 (80% of cases completed within); check it live. Premium processing for most I-129 classes is $2,965 for 15 business days.
How to comment before November 13
Comments must be submitted "on or before November 13, 2026." About 400 had been posted as of 2026-11-01, against about 27,000 on the worker grace-period proposal. The Federal Register page for the proposal links to the comment form.
- Open regulations.gov and find docket USCIS-2026-0529. Emails or letters to officials are not treated as comments, and USCIS is not accepting mailed, hand-delivered or couriered ones.
- Write about what you know first-hand, such as whether the 10-minute estimate fits an O-1 or L-1 RFE.
- Remove receipt numbers, A-numbers and other identifiers, because comments are public.
- Submit by 2026-11-13 and save the tracking number regulations.gov gives you.
How to prepare an O-1, L-1, TN or E-3 extension while the rule is pending
You do not file your own I-129. Your employer, or for many O-1 workers a US agent, is the petitioner, and its immigration attorney decides what goes in. You can help:
- Check your latest I-94 on CBP's I-94 website. Its end date, not the I-797 alone, is when your stay ends.
- Gather every prior I-797 and, if your employer shares them, the approved petitions and support letters. Note whether each approval came from USCIS, CBP or a consulate.
- Collect the class evidence in the table above: new O-1 evidence and events, current L-1 organization charts, your TN degree or license, your E-3 degree records.
- Keep proof that you maintained status, which 8 CFR 214.1(c)(6) already requires for I-129 extensions (paystubs, W-2 forms, tax returns and similar).
- Send your attorney a dated list of what changed since the last approval: duties, title, worksite, pay, reporting line. A material change can mean deference does not apply even today.
- Ask counsel about the 09/09/26 Form I-129 edition (the only one accepted from 2026-11-09), the new filing location, and PDF upload, which since 2026-10-07 covers E-3, L-1 and O-1 but not TN.
- Confirm with HR whether the 9-11 fee (in effect) applies: $4,500 on L-1 petitions, extensions included, postmarked 2026-09-09 through 2027-09-30, for covered employers (50 or more US employees, more than half in H-1B or L-1 status), per PA-2026-16; see our L-1 extension fee explainer. The deference proposal adds no fee.
If you are on F-1 or STEM OPT and moving into O-1 or TN, your first petition is new employment, so deference was never part of it. Talk to your DSO about OPT and SEVIS, and to a licensed immigration attorney about the petition. For the H-1B side, see our guide to H-1B extensions under the deference proposal; the November 2026 comment-deadline tracker lists this rule beside the OPT-fee and grace-period proposals.
Common mistakes
- Saying "deference is gone." 8 CFR 214.1(c)(5) still applies. After 2026-11-13 the comment period is closed, but the rule is still a proposal.
- Reading the FY2026 rates as your odds. They mix initial petitions and extensions and describe filed cases, not yours.
- Assuming a border or consular approval earns deference. USCIS considers, but does not defer to, CBP and State Department decisions.
- Mixing up two proposals. Ending the worker 60-day grace period (comments close 2026-11-10) is a separate rule, also only proposed; the current 60 days still applies.
- Keeping job changes from counsel. A material change can mean an amended petition. Tell your attorney and let them decide.
Frequently asked questions
What is USCIS deference to prior approvals?
It is the rule at 8 CFR 214.1(c)(5) telling USCIS to defer to its own earlier eligibility decision when it decides a Form I-129 request with the same parties and the same underlying facts. Officers may decline to defer for a material error, a material change, or new material information that hurts eligibility. It does not cover CBP or consular decisions. As of 2026-11-01 the rule is in effect.
Does the deference rule apply to O-1 and L-1 extensions?
Yes. The proposal published 2026-10-14 (RIN 1615-AD26) would remove deference for every request filed on Form I-129, so O-1, L-1, TN and E-3 extensions are covered along with H-1B. If it is finalized, same-employer, same-facts extensions in those classes would lose the regulatory instruction to defer.
Is the deference rule final?
No. As of 2026-11-01 the removal of deference is only proposed. 8 CFR 214.1(c)(5) and the matching USCIS Policy Manual guidance still apply, and only a final rule published in the Federal Register could change that and set an effective date.
When do comments on the deference rule close?
Comments must be submitted on or before November 13, 2026, through regulations.gov on docket USCIS-2026-0529. About 400 had been posted as of 2026-11-01, against about 27,000 on the worker 60-day grace-period proposal. After 2026-11-13 the comment period is closed, but the rule is still a proposal.
How many extra RFEs does DHS expect?
DHS estimates about 6,044 additional RFEs a year across 208,429 affected I-129 petitions, from a 2.9 percentage point rise in the RFE rate, at about $133,987 a year in added cost to petitioners. DHS did not break the estimate down by O-1, L-1, TN or E-3.
