Each federal remedy answers a different problem. Mandamus answers inaction. An APA challenge answers an unlawful decision. Habeas answers custody. A petition for review answers a removal order. Picking the remedy that matches the problem is the first decision in any case against an immigration agency, and using the wrong one is a common reason cases are dismissed.
Quick Facts
- Inaction: mandamus (28 U.S.C. § 1361) and APA § 706(1)
- Unlawful action: APA § 706(2), after final agency action (§ 704)
- Custody: habeas corpus (28 U.S.C. § 2241)
- Removal orders: petition for review in a court of appeals (8 U.S.C. § 1252)
- Naturalization: § 1447(b) for delay after the interview; § 1421(c) after a denial
The remedies side by side
| Problem | Remedy | Where | Main limit |
|---|---|---|---|
| The agency will not decide | Mandamus, 28 U.S.C. § 1361; APA, 5 U.S.C. § 706(1) | District court | Needs a clear duty; delay judged under TRAC |
| The agency decided unlawfully | APA, 5 U.S.C. § 706(2) | District court | Final agency action; statutes bar review of many discretionary denials |
| The agency’s own appeal route | Administrative appeal or motion (AAO, BIA) | Within the agency | Strict filing deadlines |
| A person is detained | Habeas corpus, 28 U.S.C. § 2241 | District court where held | Challenges custody, not the removal order |
| A final order of removal | Petition for review, 8 U.S.C. § 1252 | Court of appeals | 30 days from the final order |
| N-400 undecided after the interview | 8 U.S.C. § 1447(b) | District court | 120 days after the examination |
| N-400 denied after administrative review | 8 U.S.C. § 1421(c) | District court (de novo) | Requires the Form N-336 hearing first |
Mandamus and the APA: inaction versus action
For delay, the two routes largely converge. Courts in the District of Columbia treat the standards under the Mandamus Act and APA § 706(1) as essentially the same. The APA’s other half, § 706(2), is different in kind: it lets a court “hold unlawful and set aside” an agency decision that is arbitrary, capricious or contrary to law. That route requires a final agency action (5 U.S.C. § 704), and in immigration it runs into statutes that bar review of many discretionary decisions (8 U.S.C. § 1252(a)(2)(B); Patel v. Garland, 596 U.S. 328 (2022)). A more detailed comparison of how an APA delay claim differs from a mandamus claim covers pleading both.
Administrative appeals
USCIS denials can often be appealed to the Administrative Appeals Office or reopened by motion, and immigration-judge decisions go to the Board of Immigration Appeals. For an APA claim, exhaustion is required only when a statute or the agency’s rules make it mandatory (Darby v. Cisneros, 509 U.S. 137 (1993)). Where an appeal is available and adequate, however, mandamus is not.
Habeas corpus: custody, not delay
Habeas corpus orders the official holding a person to justify the detention before a judge. It is the remedy for unlawful immigration detention, filed in the district of confinement. It is not a way to obtain a benefit or to reverse a removal order: the statute makes a petition for review in the court of appeals the exclusive way to challenge a removal order (8 U.S.C. § 1252(a)(5)). See Habeas Corpus: the Order to Bring the Detained Person Before a Judge.
Naturalization’s own statutes
Naturalization has two dedicated routes that displace mandamus: a suit under 8 U.S.C. § 1447(b) when USCIS has not decided an N-400 within 120 days after the interview, and de novo review under 8 U.S.C. § 1421(c) after a denial has been reviewed at an administrative hearing on Form N-336. See Naturalization: the 120-Day Rule After the Interview.
Stays of removal
A delay suit does not stop a removal. Stopping one requires its own order: an administrative stay from ICE, a stay from the immigration court or Board, or a stay from the court of appeals. See Stays of Removal and Motions to Reopen.
