DHS Interim Final Rule
90 Fed. Reg. 47,442 · Effective Oct. 30, 2025

Elimination of the 540-Day Automatic EAD Extension — Mandamus Becomes the Primary Safety Net

DHS's Interim Final Rule removing the automatic up-to-540-day extension for Form I-765 EAD renewals took effect on October 30, 2025. Renewals filed on or after that date no longer receive any automatic extension; if USCIS does not adjudicate before the existing EAD expires, work authorization ends on the face date of the card. Categories affected include the major (c)(8), (c)(9), (c)(10), (a)(12)/(c)(19), and (c)(33) populations.

In the months since the rule took effect, the practical consequence is that I-765 mandamus has shifted from a backstop remedy invoked after the 540-day extension ran out to the primary remedy for renewal applicants approaching card expiration. The TRAC analysis has not changed in form, but factor three (health and welfare) is now satisfied much earlier in the timeline because the income-loss harm is no longer deferred. Practitioners are filing at or before the 60-day pre-expiration window where previously they would have waited eighteen months.

Practical EffectRenewal-track mandamus filings should now be calendared off the existing EAD's expiration date, not the original I-765 filing date. The TRAC factor analysis cites the IFR itself as evidence that the agency previously took responsibility for bridging its own processing delays and has now abandoned that responsibility.
USCIS Policy Memorandum
PM-602-0192 (Dec. 2025) · PM-602-0194 (Jan. 2026)

The 39-Country Adjudication Pause — Mandamus Theory After the Freeze

Two USCIS Policy Memoranda froze adjudications across a sweeping list of form types for nationals of 39 designated countries. The freeze applies to affirmative asylum, certain adjustment cases, T and U visa adjudications, and other categories — though the precise contours have shifted with each policy update.

Mandamus litigation arising from the pause divides into two analytically distinct categories. First, direct challenges to the pause policy itself under the APA and constitutional doctrine — these are class actions and individual APA suits seeking to vacate or enjoin the freeze. Second, individual mandamus actions seeking adjudication of paused cases on TRAC grounds, treating the policy pause as evidence of unreasonable delay rather than challenging the policy directly. The second framework has produced mixed early results: some district courts have ordered adjudication; others have deferred to the agency on the basis that the pause is itself an "action" that satisfies the duty to act.

Practical EffectMandamus complaints for affected nationals should plead both APA and §1361 grounds and should carefully document that the underlying application was filed pre-pause, that no individual security concern is identified, and that the pause has now extended past any reasonable interim policy review period.

2024–2025 · circuit developments

Significant federal appellate and district court decisions
Federal Circuit Court of Appeals
Da Costa v. Immigration Investor Program Office · D.C. Cir. (2024)

EB-5 Mandamus and the Limits of "Agency Priority" Defenses

The D.C. Circuit addressed an I-526 EB-5 mandamus and rejected the government's invocation of TRAC factor four (effect on competing agency priorities) as a categorical defense to multi-year delays. The court emphasized that USCIS's own published processing-time projections were not consistent with the agency's litigation position about resource constraints and that the agency cannot simultaneously publish processing-time targets and disclaim them in mandamus litigation.

Practical EffectEvery USCIS mandamus complaint should cite the agency's posted processing-time data for the relevant form and category as TRAC factor one evidence. Where the case is materially older than the agency's own published targets, the rule-of-reason analysis becomes nearly automatic.
BIA Precedent
Matter of Garcia · 28 I&N Dec. 693 (BIA 2023)

Choice of Law in Immigration Court Follows Venue — And Only the Parties Can Move to Change It

The Board confirmed that the controlling circuit law in removal proceedings is determined by the geographic location of the Immigration Court where venue lies, and reiterated that only a party may initiate a venue change by motion. The decision matters for mandamus practice because it crystallizes the stakes of an Immigration Judge's failure to rule on a properly filed venue-change motion: the procedural delay is also a choice-of-law decision being made by inaction.

Practical EffectEOIR mandamus complaints seeking to compel a ruling on a stalled venue motion should now invoke Garcia for the proposition that the Immigration Judge's non-decision is itself producing the choice-of-law consequence the party sought to avoid.

Foundational Authority · the framework

Decisions that anchor modern mandamus practice and remain controlling
Sixth Circuit
Barrios Garcia v. U.S. Dep't of Homeland Sec. · 25 F.4th 430 (6th Cir. 2022)

Five-Year U-Visa Delay Is Unreasonable Under TRAC

Although decided in the U-visa context, Barrios Garcia has become the standard authority for the proposition that USCIS delays approaching or exceeding two years are presumptively unreasonable absent specific case-by-case justification. The Sixth Circuit's analysis of TRAC factor three (health and welfare) is now routinely cited in mandamus filings for I-485, I-130, and asylum delays.

Practical EffectCite Barrios Garcia in every mandamus complaint involving a humanitarian benefit category or a delay exceeding two years. Pair it with the agency's published processing-time data for the form at issue.
Second Circuit
Singh v. USCIS · 878 F.3d 441 (2d Cir. 2017)

8 U.S.C. § 1252(a)(5) Channels Removal-Related Review

The Second Circuit confirmed that collateral APA-based challenges that effectively attack removal-proceeding decisions are foreclosed by §1252(a)(5)'s channeling provision. The case is now standard authority for the doctrinal point that issues arising from removal proceedings must be litigated through the petition-for-review process, not through alternative federal-court vehicles. The same channeling logic constrains attempts at interlocutory federal review of Immigration Court rulings.

Practical EffectWhere the target of a contemplated mandamus is an Immigration Court ruling, the only realistic vehicle is mandamus against the Attorney General under 28 U.S.C. § 1361 — not a collateral APA action and not an interlocutory petition for review.
Second Circuit (Summary Order)
Ngassaki v. Holder · (2d Cir. Sept. 13, 2013)

Arbitrary Denial of an EOIR Venue-Change Motion Is Reversible Error

The Second Circuit vacated a Buffalo Immigration Court removal order on the ground that the Immigration Judge had arbitrarily denied a motion for change of venue. The decision is direct authority for the proposition that EOIR venue-change rulings are reviewable on the merits at the petition-for-review stage — though only after the case has been litigated to a final order in the disputed venue. The structural cost Ngassaki implies is exactly what an interlocutory mandamus action seeks to avoid.

Practical EffectNgassaki is both shield and sword. As a shield, it confirms that an Immigration Judge cannot deny a venue motion arbitrarily. As a sword, it makes clear that the only realistic interim remedy is mandamus, because final-order review comes only after years of litigation in the wrong forum.
BIA Precedent
Matter of Rahman · 20 I&N Dec. 480 (BIA 1992)

The BIA Does Not Ordinarily Entertain Interlocutory Appeals

The Board's foundational statement of its restrictive interlocutory-appeal practice. Rahman permits interlocutory review only where the Board "deems it necessary to address important jurisdictional questions regarding the administration of the immigration laws, or to correct recurring problems in the handling of cases by Immigration Judges." In practice, the Board dismisses the vast majority of interlocutory appeals on this basis, leaving federal-court mandamus as the only path for relief from an Immigration Court that has refused to act.

Practical EffectDocument the Rahman-based BIA dismissal in any subsequent federal mandamus complaint. The closed administrative door is a key element of the "no other adequate remedy" analysis under 28 U.S.C. § 1361.
District Court · Foundational
Liu v. Novak · 509 F. Supp. 2d 1 (D.D.C. 2007)

Pre-Decision Agency Delay Is Reviewable — The Duty to Act Is Independent of Merits Discretion

The District of Columbia's foundational district-court decision establishing the framework on which virtually all modern USCIS mandamus rests. Liu held that USCIS's duty to adjudicate a pending application is non-discretionary even where the underlying merits decision lies within agency discretion. The case continues to anchor the duty-to-act / discretion-to-decide distinction that courts use to reject government claims that all pre-adjudication agency conduct is committed to discretion.

Practical EffectCite Liu for the elemental proposition every mandamus complaint requires: the agency has a non-discretionary duty to act. Pair it with TRAC v. FCC for the unreasonableness analysis.
D.C. Circuit · Foundational
Telecomms. Research & Action Ctr. v. FCC · 750 F.2d 70 (D.C. Cir. 1984)

The TRAC Factors

The six-factor framework that governs every federal-court unreasonable-delay analysis: (1) rule of reason; (2) congressional timetables; (3) human health and welfare; (4) competing agency priorities; (5) interests prejudiced by delay; (6) no impropriety required. TRAC was decided in the FCC regulatory context but has been universally adopted in immigration mandamus and APA delay practice.

Practical EffectEvery immigration mandamus complaint should organize its core legal section around the TRAC factors, applied to the specific form type and fact pattern at issue.
