If USCIS has not decided your N-400 within 120 days of the interview, 8 U.S.C. § 1447(b) lets a federal court take jurisdiction over the application and either decide it or send it back with a deadline — a hard statutory clock, not a debate over what "unreasonable" means.
The interview went fine. The officer said the application was recommended for approval pending background checks, or handed you a Form N-652 checked "a decision cannot yet be made," and told you to expect a notice. Months pass. Case-status inquiries produce form responses about "additional review." No oath ceremony is scheduled, and no one can say when one will be. For many applicants this stretch is more frustrating than the years of green-card processing that came before it, because the finish line is in sight and nothing is moving.
The reasons vary. Some cases are held for security or background-check processing that runs long. Some are routed into internal review programs that USCIS does not explain to the applicant. Some sit because an issue surfaced at the interview — extended travel, a tax question, an old arrest, a possible inconsistency with an earlier filing — and the officer wanted a supervisor or another unit to look at it. Whatever the cause, the law treats the 120th day after the interview as a line: on that day, the applicant acquires a statutory right to go to federal court.
This remedy is specific to the post-interview stage. If you are still waiting for the interview itself, § 1447(b) does not apply yet; a pre-interview delay is analyzed as an ordinary unreasonable-delay claim under the mandamus statute and the Administrative Procedure Act, which is a harder, more forum-dependent case. The two are different tools, and the first question we ask is which stage you are in.
The statute is short. Under 8 U.S.C. § 1447(b), "[i]f there is a failure to make a determination under section 1446 of this title before the end of the 120-day period after the date on which the examination is conducted under such section, the applicant may apply to the United States district court for the district in which the applicant resides for a hearing on the matter. Such court has jurisdiction over the matter and may either determine the matter or remand the matter, with appropriate instructions, to the Service to determine the matter." USCIS's own regulation says the same thing from the agency's side: a decision "shall be made at the time of the initial examination or within 120-days after the date of the initial examination," and USCIS "shall grant the application if the applicant has complied with all requirements for naturalization." 8 C.F.R. § 335.3(a).
"Examination" means the interview. The government has argued that the examination is a process that continues until background checks are complete, so that the 120 days never begins to run while the FBI or another agency is still working — a position adopted by a few early district-court decisions, most prominently Danilov v. Aguirre, 370 F. Supp. 2d 441 (E.D. Va. 2005). The Fifth Circuit rejected that reading by name in Walji v. Gonzales, 500 F.3d 432 (5th Cir. 2007), holding that the "examination" is a discrete event — the initial interview — and that the 120-day period runs from the date that interview concludes, whether or not a background check is still pending. The Fourth Circuit has described the clock the same way. The clock starts on the day you sit down with the officer.
Filing the petition shifts the case to the court. Every court of appeals to decide the question has held that a § 1447(b) petition vests the district court with exclusive jurisdiction over the application: United States v. Hovsepian, 359 F.3d 1144 (9th Cir. 2004) (en banc); Etape v. Chertoff, 497 F.3d 379 (4th Cir. 2007); Bustamante v. Napolitano, 582 F.3d 403 (2d Cir. 2009). Once the petition is on file, USCIS cannot grant or deny the application on its own unless and until the court remands it — and a decision the agency purports to issue after filing, without a remand, is without effect. This is the feature that makes § 1447(b) different from every other immigration delay suit. In a mandamus case the agency can moot the lawsuit by deciding, favorably or not, the moment it chooses. Here the agency must come to court to get the case back.
The court has two options, and it chooses. The statute says the court "may either determine the matter or remand the matter, with appropriate instructions." A court that determines the matter holds its own hearing on eligibility, and if you are eligible it can grant the application and administer the oath of allegiance in the courtroom — federal district courts are "eligible courts" authorized to administer the oath under 8 U.S.C. § 1421(b), and that is exactly what happened in Hovsepian, where the district court ordered the applications granted and swore the applicants in itself. In practice, most courts remand — the government almost always asks them to, usually representing that the holdup is nearly resolved — but they remand with instructions, typically a deadline by which USCIS must decide, and sometimes a provision that the court will decide the case itself if the deadline is missed. Courts have also declined to remand where USCIS shows no good cause for the delay or will not commit to a prompt decision. The instructions are where the leverage is, and negotiating them is much of the work.
Because Congress wrote a specific review channel with a specific deadline, the general delay statutes take a back seat. Courts have held that before day 120 there is no mandamus remedy for a post-interview naturalization delay, because § 1447(b) is the exclusive scheme, see Danilov, 370 F. Supp. 2d at 444–45; after day 120, § 1447(b) supplies the cause of action directly. That means none of the machinery that makes ordinary delay suits uncertain — the six-factor TRAC balancing, the argument that other applicants would be pushed back in line, the search for a forum receptive to delay claims — is part of a § 1447(b) case. There is no administrative remedy to exhaust first. Venue is fixed by statute in the district where you live.
The core § 1447(b) posture — the statutory right has ripened
This is exactly what the statute was written for. The only jurisdictional facts are the interview date and the absence of a decision 120 days later; nothing about the reason for the delay changes the right to file. We confirm the dates from the interview notice and the N-652, send a final written inquiry that documents the wait, and prepare the petition. The government's answer is due 60 days after service, and it is common for the case to be decided — or for the government to come to court seeking a remand with a deadline — inside that window.
A favorable interview followed by silence
A recommendation for approval is not a determination; the application remains undecided until USCIS actually grants it, and a grant is not complete until the oath. Where the interview went well and the record is clean, a § 1447(b) petition is a strong lever: there is no eligibility dispute for the government to litigate, so the realistic outcomes are a prompt approval on remand or, if the court is willing to keep the case, a hearing at which the judge grants the application and administers the oath in court — you leave the courthouse a citizen. This is also the posture in which we push hardest on the remand instructions — a short deadline and, where the court will include it, direction that the oath be administered promptly on approval.
The stated reason is security or name-check processing, or an unexplained hold
This is the most common reason for post-interview delay and, legally, the weakest reason for USCIS to resist a petition. The 120-day clock runs from the interview whether or not the background check is finished, and the government's argument that the "examination" continues until the checks clear was rejected by the Fifth Circuit in Walji. A court will not skip the checks — a remand order typically directs USCIS to complete them and decide by a date certain — but the open-ended wait ends.
A continued examination under 8 C.F.R. § 335.3(b)
The regulation lets USCIS continue the initial examination for one reexamination to let the applicant overcome deficiencies, but it requires that reexamination to be scheduled within the same 120-day period after the initial examination. The government sometimes argues that a second interview restarted the clock. The better reading of the statute and regulation is that the clock runs from the initial examination — the Fifth Circuit in Walji pointed to this very regulation, which requires any reexamination to happen inside the original 120 days, as proof that a second interview does not restart the period. Where a second interview or a request for evidence is in the picture, we analyze the dates carefully before filing, because the government will raise this as a threshold defense.
An eligibility issue surfaced at the interview and the case has gone quiet
This is where candor matters most. A § 1447(b) petition puts your eligibility in front of a federal judge and an Assistant U.S. Attorney, both of whom will read the file. If the delay reflects a real problem — a continuous-residence break, an unfiled tax year, an arrest that was not disclosed, a prior filing that conflicts with the N-400 — the petition accelerates the answer, and the answer may be a denial. Sometimes that is still the right call: a denial can be contested through the administrative hearing under 8 U.S.C. § 1447(a) and then de novo review in district court under 8 U.S.C. § 1421(c), and a decision is better than indefinite limbo. But we do that analysis with you before filing, not after.
Pre-interview N-400 delay — not a § 1447(b) case
The 120-day clock has not started. A delay in scheduling the interview is an ordinary unreasonable-delay claim under the mandamus statute and the APA, judged under the TRAC factors and heavily dependent on the forum and the length of the wait. It can be worth bringing, but it is a different and harder case, and we assess it under the framework described on our unreasonable-delay page rather than this one.
Section 1447(b) is the right tool for one specific posture — a naturalization application undecided 120 days after the interview. These pages cover the neighboring situations.

Most immigration delay suits ask a court to decide whether a wait is "unreasonable," and the answer depends on the judge, the forum, and the government's story about its backlog. Section 1447(b) is different. Congress set the deadline, said what happens when it is missed, and handed the case to the court. Attorney Ryan Locke has spent nearly his whole career litigating against the government, and this is the one immigration delay posture where the statute does most of the arguing for the client. It is not for everyone: an applicant whose case is stalled because of a genuine eligibility problem will not be helped by moving the decision to a courthouse. We will tell you which case yours is before a petition is drafted.
This page describes how § 1447(b) petitions are generally analyzed. It is general information, not legal advice about your application and not a prediction of any result. Whether a petition is the right move depends on your interview date, the reason for the delay, the state of your record, and the practice of the district court where you live — all of which we assess, and are upfront about the cost of, before any work begins.
