The Southern District of New York is the most internally divided mandamus forum in the Second Circuit. Whether a delay claim survives a motion to dismiss here has historically turned less on how long the application has been pending than on how the claim is pleaded — and on which judge draws the case. This guide sets out the venue rules that put a case in SDNY, the Second Circuit authority that governs it, and the district's own, sharply split, published record.
Getting the case here: the venue analysis
A civil action against federal officers sued in their official capacity is governed by 28 U.S.C. § 1391(e)(1), which is considerably more generous than the ordinary venue statute. Venue is proper in any judicial district in which:
- § 1391(e)(1)(A) — a defendant resides. For officers sued in an official capacity, residence means the district of the officer's official station. The Secretary of Homeland Security and the Director of USCIS sit in Washington, D.C., which is why so many delay cases can be filed in the District of Columbia regardless of where the plaintiff lives.
- § 1391(e)(1)(B) — a substantial part of the events or omissions giving rise to the claim occurred. In a delay case the operative omission is the failure to decide, which points at whichever office is actually sitting on the file — a field office, a service center, or a national unit.
- § 1391(e)(1)(C) — the plaintiff resides, so long as no real property is involved in the action. For an individual with a stalled application this is the simplest and most common hook, and it is the one that requires the least pleading.
The three prongs are independent. Satisfying any one of them makes venue proper, and a plaintiff with more than one available prong has a genuine choice of forum — which is where the case law below starts to matter.
SDNY covers New York and Bronx Counties together with Westchester, Rockland, Putnam, Orange, Dutchess and Sullivan — a reach that extends well up the Hudson Valley. For a petitioner living in any of them, the § 1391(e)(1)(C) residence prong is the straightforward route, and the New York City Field Office at 26 Federal Plaza supplies the § 1391(e)(1)(B) hook in most Manhattan-adjudicated matters.
Pleading venue on the location of the office holding the file can point away from the district you want. Much New York-area work is processed at the Vermont Service Center, which sits in the District of Vermont; the National Benefits Center, the Immigrant Investor Program Office and the National Visa Center all sit elsewhere again. Where several prongs are available, plead the one you actually intend to rely on, and expect the government to test it. The transfer analysis under 28 U.S.C. § 1404(a) is treated separately in Defending Venue Transfer, and the broader forum-selection question in Choice of Forum.
The governing law in the Second Circuit
There is no “writ” to petition for
Rule 81(b) of the Federal Rules of Civil Procedure abolished the writ of mandamus in the district courts; relief is sought instead as an ordinary civil action in the nature of mandamus under 28 U.S.C. § 1361. See In re Nagy, 89 F.3d 115, 116 (2d Cir. 1996). This is not pedantry. In Espin v. Gantner, discussed below, the court opened its jurisdictional analysis by observing that the petitioner “prays for a form of relief abolished over seventy years ago with the promulgation of the Federal Rules of Civil Procedure.” Captioning matters.
The three elements
A plaintiff seeking relief in the nature of mandamus must establish:
- a clear and indisputable right to the relief sought — In re Drexel Burnham Lambert Inc., 861 F.2d 1307, 1312 (2d Cir. 1988);
- a plainly defined and peremptory duty on the defendant's part to do the act in question — Lovallo v. Froehlke, 468 F.2d 340, 343 (2d Cir. 1972); and
- that no other adequate remedy is available — id.
Relief will not issue to compel a discretionary act. Anderson v. Bowen, 881 F.2d 1, 5 (2d Cir. 1989); Work v. United States ex rel. Rives, 267 U.S. 175, 177 (1925); Heckler v. Ringer, 466 U.S. 602, 616 (1984); Pittston Coal Group v. Sebben, 488 U.S. 105, 121 (1988). The entire fight in a delay case is therefore over characterization: the government says the pending application is a discretionary matter, and the plaintiff answers that the decision may be discretionary but the duty to decide is not.
This is the decision the government cites in almost every Second Circuit delay case, for the sentence that judicial creation of a duty would carry “the potential for mischievous interference with the functioning of already overburdened administrative agencies.” 569 F.2d at 1182. The sentence is real. Its subject is not.
The duty the court declined to create was a duty to conduct and complete a discretionary fraud investigation that a consular officer had requested as a predicate to issuing visas abroad. The Second Circuit was careful to separate that from the agency's duty to act on the preference petitions themselves — a duty it held had already been discharged when the petitions were approved: “The INS's duty in the matter ended there.” The court affirmed dismissal while expressly vacating the district court's contrary statement that the agency had a further duty to investigate.
Wan Shih Hsieh is authority that a discretionary investigative function cannot be compelled. It is not a holding that an agency may leave indefinitely undecided a benefit application it is required to decide. Briefing that does not draw that line concedes the strongest adverse authority in the circuit.
The APA route, and why it usually matters more
Two APA provisions carry the weight. 5 U.S.C. § 555(b) requires that “within a reasonable time, each agency shall proceed to conclude a matter presented to it,” and 5 U.S.C. § 706(1) authorizes a reviewing court to “compel agency action unlawfully withheld or unreasonably delayed.” The APA is not itself a grant of jurisdiction — Califano v. Sanders, 430 U.S. 99, 105–07 (1977) — but in combination with the federal-question statute, 28 U.S.C. § 1331, it supplies one.
The six-factor framework for assessing whether a delay is unreasonable comes from In re Telecommunications Research & Action Center v. FCC, 750 F.2d 70, 79–80 (D.C. Cir. 1984). District courts in this circuit apply the TRAC factors, but they arrive from another circuit — a distinction worth preserving when a government brief treats them as though they settled the question. The factors are set out at length in The TRAC Factors, and the choice between the two theories in APA Delay vs. Mandamus.
What SDNY has actually held
This is where SDNY departs from its neighbors. The district's published record on delay claims is genuinely divided, and the division runs judge by judge rather than year by year. Both anchors of the split remain on the books.
The court dismissed a petition seeking adjudication of an I-485 filed in 2002, holding that it lacked jurisdiction because the adjustment process “is not susceptible to mandamus jurisdiction because it is wholly discretionary with the Attorney General.” 381 F. Supp. 2d at 265. The opinion then collects roughly fifteen S.D.N.Y. decisions declining mandamus jurisdiction over adjustment-related claims — the single most concentrated body of adverse authority in the district.
It also rejected the claim on the merits, reading INS v. Miranda, 459 U.S. 14, 19 (1982), for the proposition that the passage of time cannot standing alone support an unreasonable-delay claim, and observing that the agency's New York District then had on the order of a quarter of a million applications pending. Any SDNY filing should be drafted against this opinion rather than around it.
The court denied the government's motion to dismiss an action over an I-485 that had been pending more than five years behind an incomplete FBI name check. It framed the question as one “that has divided district courts across the country, and remains open in the Second Circuit,” and found jurisdiction under 28 U.S.C. § 1331 together with APA § 555(b), on the ground that the claim was “not patently without merit.”
The opinion is also the best single map of the split, cataloguing the S.D.N.Y. decisions on each side by name and judge.
Saleh appears on both sides of the ledger, and that is the whole lesson. Espin cites it at 511 among the decisions declining jurisdiction. Nigmadzhanov cites it at 512 for the holding that the court “has jurisdiction of Plaintiff['s] APA claim pursuant to 28 U.S.C. § 1331.” Both citations are accurate. The court declined mandamus jurisdiction under § 1361 while accepting federal-question jurisdiction over the APA claim.
The vehicle, not the length of the delay, decided the case.
The split, by judge
As catalogued in Nigmadzhanov and Espin, the district's published decisions line up roughly as follows:
| Position | Decisions |
|---|---|
| Jurisdiction declined | Espin v. Gantner (Preska, J.); Vladagina v. Ashcroft (Batts, J.); Hui Jin Zheng v. Reno, 166 F. Supp. 2d 875 (Koeltl, J.) |
| Jurisdiction found | Kim v. Ashcroft, 340 F. Supp. 2d 384 (Scheindlin, J.); Batista v. INS (Mukasey, J.); Cordoba v. McElroy, 78 F. Supp. 2d 240 (Kaplan, J.); Nigmadzhanov v. Mueller (McMahon, J.) |
| Split by vehicle | Saleh v. Ridge (Swain, J.) — no § 1361, yes § 1331 + APA |
Plead the § 555(b) / § 706(1) claim under § 1331 as the primary theory, and § 1361 in the alternative — never the reverse. Judges in this district who have refused relief under § 1361 have repeatedly gone on to entertain the APA claim on its merits. A complaint that leads with the mandamus statute walks into the Espin line; one that leads with the APA is met by Nigmadzhanov and Saleh. Because assignment is random, a candid assessment of an SDNY filing has to price in that spread.
The decisions discussed above are this district's published landmarks. They are not a survey of how the district ruled last month, and no honest guide can offer one. The overwhelming majority of USCIS delay cases end without a written opinion — the agency adjudicates after service and the parties file a stipulation of dismissal, or the court disposes of the matter by unpublished order. Those dispositions never enter the reported case law and are not searchable in the free databases.
So the published line tells you how this bench reasons when it does write. What happens in the ordinary case is practice, not precedent, and it is described as such wherever it appears on this page.
Estimated disposition posture
My estimate is that roughly 82% of resolved SDNY cases end in voluntary dismissal after USCIS adjudication, with about 11% dismissed on a government Rule 12 motion. The total "case-reached-a-judge" rate of about 14% is among the lowest in the seven districts I track. These are estimates synthesized from secondary sources — see the flagship comparison for methodology.
Strategic considerations
- Lead with the APA. The single highest-value drafting decision in this district, for the reasons set out above.
- Draft against Espin. It is the most-cited adverse decision in the district and it collects fifteen more. Address the discretion argument in the complaint rather than waiting for the reply.
- Distinguish Wan Shih Hsieh explicitly. Separate the discretionary investigation it actually concerned from the non-discretionary duty to decide a pending application.
- Caption the action correctly — a civil action in the nature of mandamus, not a “petition for a writ.”
- Plan for mootness from the outset. Most cases end when the agency adjudicates. That is the desired result, but it forecloses a merits ruling and affects any fee application — see EAJA Attorneys' Fees.
When SDNY is the right choice
SDNY is the right forum when the petitioner lives within the district, when the New York City Field Office is the adjudicating office, or when the petitioner has venue flexibility under § 1391(e) and prefers a Second Circuit forum. The bench is unusually experienced in administrative law, which cuts both ways: the analysis will be rigorous, and a well-pleaded APA claim gets a serious reading.
Against EDNY next door, the honest distinction is not that one bench is friendlier. It is that SDNY's published record is divided while EDNY's is thinner and more procedural. For a petitioner with a genuine choice, the deciding factors are residence, the location of the adjudicating office, and tolerance for the assignment spread described above — never a general preference between the two courts.
