Immigration Mandamus (USCIS & Visa Delays)
A decision, not an approval
An application has been pending for years. The online status has not changed, the service request produced a form letter, and the congressional inquiry produced the same one. This section is about the lawsuit that follows: a complaint in a federal district court asking the court to order a decision on a case that has stopped moving.
The claim rests on 5 U.S.C. § 555(b), which requires an agency to conclude a matter presented to it within a reasonable time, and 5 U.S.C. § 706(1), which lets a court compel action unlawfully withheld or unreasonably delayed, usually pleaded alongside 28 U.S.C. § 1361. Reasonableness is measured by the six factors of Telecommunications Research & Action Center v. FCC, 750 F.2d 70 (D.C. Cir. 1984), and the claim is confined by Norton v. Southern Utah Wilderness Alliance, 542 U.S. 55 (2004), to a discrete action the agency is required to take. Two points are misstated constantly. First, 8 U.S.C. § 1571(b) sets a target: it is the sense of Congress that processing should be completed within 180 days. It is not a deadline, and no case is won by pointing at it alone. The genuine statutory clock is narrower — 8 U.S.C. § 1447(b) lets a naturalization applicant go to the district court when 120 days pass after the examination, and 8 C.F.R. § 335.3(a) requires the agency itself to grant or deny within 120 days of that interview. Second, the relief is a decision, not an approval. A court that grants everything asked for still leaves the agency free to deny, and denial after an order to decide is compliance.
Nothing here evaluates eligibility, and nothing here helps with a case in removal proceedings or on appeal from a denial. The general administrative-law framework, including how the same test applies outside immigration, is in Agencies & Administrative Law. Service, venue and the government's 60-day response are in The Practice Desk. The TRAC decision itself is read in Case Files.
