Most delay cases that lose do so for one of a handful of reasons, and most of those reasons are visible before the case is filed. They fall into two groups: the court decides it cannot hear the case, or it hears the case and finds the delay acceptable.

Quick Facts

  • Most common loss: the delay is found reasonable under the TRAC factors
  • Threshold loss: no jurisdiction, often under 8 U.S.C. § 1252(a)(2)(B)(ii)
  • Usual vehicle: a government motion to dismiss, Fed. R. Civ. P. 12(b)(1) or 12(b)(6)
  • Not a mandamus element: irreparable harm

1. The delay is not unreasonable

This is the most common outcome. Courts weigh the six factors from Telecommunications Research & Action Center v. FCC, 750 F.2d 70, 80 (D.C. Cir. 1984), and a wait that feels long to the applicant can still fall within the “rule of reason,” especially when the agency explains it with security vetting or high volume. Courts are also reluctant to order relief that would only move one applicant ahead of others in the same line (In re Barr Laboratories, Inc., 930 F.2d 72, 75 (D.C. Cir. 1991)).

2. No clear duty to act

Mandamus and the APA reach only a “discrete agency action that it is required to take” (Norton v. Southern Utah Wilderness Alliance, 542 U.S. 55, 64 (2004)). A case fails when the court finds no such duty, for example where a consular officer has already refused a visa and judges disagree about whether anything remains to be compelled, or where the relief requested is a particular outcome rather than a decision.

3. A statute removes jurisdiction

Congress has withdrawn federal-court review of many discretionary immigration decisions. Under 8 U.S.C. § 1252(a)(2)(B)(ii), courts lack jurisdiction over decisions or actions the statute places in the agency’s discretion. Several courts of appeals have read that provision to bar suits over the pace of adjustment-of-status adjudications (Cheejati v. Blinken, 106 F.4th 388 (5th Cir. 2024); Kanapuram v. Director, USCIS, 131 F.4th 1302 (11th Cir. 2025)), while other courts disagree. Where a case falls on that line depends heavily on the form involved and the circuit.

4. Another remedy was available

Mandamus is available only when no other adequate remedy exists. A naturalization applicant whose case is undecided 120 days after the interview has a specific statutory route, 8 U.S.C. § 1447(b). A denied application usually has an administrative appeal or motion, and a removal order goes to a court of appeals by petition for review. Choosing the wrong vehicle is a common and avoidable reason for dismissal.

5. The case becomes moot

If the agency decides the application while the case is pending, whether by approval, denial or a new refusal, there is usually nothing left for the court to order, and the case is dismissed as moot. In Sorbi v. Rubio, No. 25-cv-2353 (D.D.C. Aug. 24, 2026), a spouse’s visa application that had sat in administrative processing was re-refused under a presidential proclamation during the lawsuit, and the court dismissed the delay claim as moot.

6. The delay is the applicant’s

Courts will not order an agency to end a delay the applicant caused or the law requires: an unanswered request for evidence, a missed biometrics appointment, or a priority date that is not current, so that no visa number is available.

7. Procedural defects

Cases also fail for reasons unrelated to the merits: suing officials who have no role in the decision, filing in a district where venue is improper, or failing to serve the U.S. Attorney, the Attorney General and each agency within 90 days (Fed. R. Civ. P. 4(i), 4(m)).

Two misconceptions

Exhaustion. A person bringing an Administrative Procedure Act claim generally does not have to exhaust administrative appeals unless a statute or the agency’s rules require it (Darby v. Cisneros, 509 U.S. 137 (1993)). Informal steps such as service requests are practical, not legal, prerequisites.

Irreparable harm. Irreparable harm is a requirement for a preliminary injunction, not for mandamus. In a delay case, harm enters the analysis through the TRAC factors that weigh human welfare and prejudice. The government’s arguments are usually built around these points; for a fuller treatment see the defenses the government raises in its motions to dismiss.
