N-400 Delay After Interview: 120-Day Federal Court Action
USCIS generally must decide a naturalization application at the initial examination or within 120 days afterward. If an N-400 remains undecided beyond that period, federal law may allow the applicant to ask a U.S. district court to take jurisdiction over the naturalization case.
A Long-Pending N-400 Can Eventually Become a Federal Court Matter
Some naturalization applicants complete the N-400 interview but do not receive an approval or denial. USCIS may continue the examination, request evidence, conduct additional review, or leave the application pending.
Federal law provides a specific remedy when USCIS fails to make a determination within the statutory period following the naturalization examination.
The remedy is found in 8 U.S.C. § 1447(b). It is fundamentally different from Form N-336 because there has not yet been a naturalization denial to appeal.
Can You Sue USCIS If N-400 Has Been Pending More Than 120 Days?
Potentially, yes. Under 8 U.S.C. § 1447(b), if USCIS fails to make a determination before the end of the 120-day period after the examination conducted under 8 U.S.C. § 1446, the applicant may apply to the U.S. district court for the district in which the applicant resides.
The statute gives that court jurisdiction over the naturalization matter. The court may either determine the application itself or remand the matter to USCIS with appropriate instructions.
USCIS itself explains its current rule more simply: if a decision is not issued within 120 days of the naturalization interview, the applicant may request judicial review in district court.
The 120-Day Rule
The statutory remedy works together with the regulations governing USCIS's obligation to decide the N-400 following examination.
§ 1447(b)
If USCIS fails to determine the naturalization application within 120 days after the examination under 8 U.S.C. § 1446, the applicant may seek a hearing in the U.S. district court for the district where the applicant resides.
§ 335.3
The regulation provides that USCIS should grant or deny the naturalization application at the initial examination or within 120 days after the initial examination.
§ 1446
Section 1446 governs the investigation and examination of the applicant that forms the statutory reference point for § 1447(b).
When Does the 120-Day Period Begin?
The relevant date is not necessarily the N-400 filing date.
Filing Does Not Start the § 1447(b) Clock
An application can be pending for many months before the naturalization examination occurs. Section 1447(b) is tied to the examination, not simply to the number of days since Form N-400 was filed.
The Examination Is the Critical Event
Current USCIS policy describes the judicial remedy as becoming available when USCIS does not issue a decision within 120 days after the naturalization interview.
Federal Jurisdiction May Become Available
If USCIS still has not made a determination, the applicant may evaluate a federal district court action under § 1447(b).
Does a Second Interview Restart the 120-Day Period?
The naturalization regulation allows USCIS to continue the initial examination for one reexamination where the applicant must overcome deficiencies or submit additional evidence.
Importantly, 8 C.F.R. § 335.3 states that the reexamination on a continued case is generally to be scheduled within the 120-day period after the initial examination. The regulation therefore continues to use the initial examination as the operative reference point rather than creating a new regulatory 120-day period every time USCIS continues the case.
The procedural history should nevertheless be reviewed carefully before federal litigation, particularly where there were unusual examinations, withdrawals, missed appointments, or other events.
A § 1447(b) Case Is More Than a Request to “Speed Up USCIS”
Congress expressly gave the district court jurisdiction over the naturalization matter once the statutory conditions are satisfied.
Section 1447(b) Is Not the Same as Review After an N-400 Denial
8 U.S.C. § 1447(b)
This provision concerns a naturalization application that remains undecided after the statutory post-examination period.
There is no denial to challenge and therefore no N-336 denial review to exhaust before invoking this specific delayed-case provision.
8 U.S.C. § 1421(c)
If USCIS denies the N-400, the applicant ordinarily proceeds through the administrative N-336 hearing process.
After the required administrative review, qualifying applicants may seek de novo federal district court review under 8 U.S.C. § 1421(c).
A Delayed Case Should Be Reviewed Before Forcing a Decision
Delay can be frustrating, but faster adjudication is not always strategically beneficial if the underlying N-400 contains an unresolved eligibility problem.
Establish the exact date of the naturalization examination and calculate the 120-day period accurately.
Review any Form N-652, requests for evidence, interview notes, correspondence, online status history, or other information that may reveal what USCIS is examining.
A federal lawsuit should not be used merely to obtain a faster denial. Criminal history, immigration history, residence, prior green-card eligibility, good moral character, and other known problems should be analyzed first.
FOIA records, prior immigration filings, criminal records, travel history, tax records, or other evidence may need to be reviewed before litigation.
The objective may be a prompt USCIS adjudication, a remand under judicial supervision, or, in an appropriate case, judicial determination of the naturalization application.
Some Delayed Naturalization Cases Require More Caution
The existence of federal jurisdiction does not mean that immediate litigation is the best strategy in every case.
A delayed case involving questions about whether permanent residence was lawfully obtained can present consequences beyond the timing of naturalization.
If USCIS appears to be investigating prior statements or alleged fraud, the historical record should be evaluated before attempting to force a decision.
Criminal issues can affect good moral character, statutory eligibility, removability, or the lawfulness of permanent residence depending on the circumstances.
Extensive travel, long absences, foreign residence, or unusual tax positions should be understood before asking a court to accelerate adjudication.
The existence of additional agency review may influence litigation strategy and the likelihood that the government will request a remand rather than immediate adjudication by the court.
What If the N-400 Is Delayed Before the Interview?
Section 1447(b) specifically depends on the passage of 120 days after the naturalization examination. It is therefore not the same remedy for an applicant whose N-400 has been pending for a long time but who has never received the examination or interview.
Pre-examination delay cases may involve different administrative or federal litigation theories, including potential mandamus or Administrative Procedure Act claims depending on the circumstances and controlling law.
Those remedies have different requirements and should not be confused with the express post-examination jurisdiction created by § 1447(b).
A Practical § 1447(b) Review
Before filing, the procedural and substantive naturalization record should be analyzed together.
Confirm the Examination
Establish when the naturalization interview or examination occurred and preserve evidence of that date.
Calculate 120 Days
Determine whether the statutory period has actually expired without USCIS issuing a determination.
Review the Entire N-400 Problem
Identify any substantive issue that may explain the delay or create risk if adjudication is accelerated.
Evaluate the Federal District and Procedure
Section 1447(b) directs the applicant to the U.S. district court for the district in which the applicant resides. Federal pleading, service, jurisdictional, and local procedural requirements must then be addressed.
Decide the Litigation Objective
Determine whether the case should seek judicial adjudication, remand with instructions, or another appropriate resolution.

N-400 Delays and the 120-Day Rule
Does USCIS have 120 days to decide an N-400 after the interview?
Federal regulations provide that the decision should be made at the initial examination or within 120 days afterward. Current USCIS policy likewise states that an applicant may seek judicial review if a decision is not issued within 120 days of the interview.
Is the 120 days counted from the date I filed N-400?
No. Section 1447(b) is tied to the naturalization examination, not merely to the filing date of Form N-400.
What can the federal judge do?
The statute authorizes the district court either to determine the naturalization matter or to remand it to USCIS with appropriate instructions.
Where is a § 1447(b) lawsuit filed?
The statute provides for filing in the U.S. district court for the district in which the naturalization applicant resides.
Do I need to file Form N-336 first?
Form N-336 concerns administrative review of an N-400 that USCIS has already denied. Section 1447(b) concerns a different situation: USCIS has not issued a decision within the statutory period after examination.
Does an RFE automatically restart the 120-day period?
The governing regulation continues to measure the USCIS decision period from the initial examination and provides that a reexamination on a continued case generally should occur within that same 120-day period. Individual procedural histories should still be reviewed before litigation.
Can I use § 1447(b) if USCIS has never interviewed me?
Section 1447(b) is specifically tied to the post-examination 120-day period. A long delay before the examination may require a different legal analysis.
Should every applicant sue as soon as 120 days expire?
No. Before forcing adjudication, the applicant should understand why the case may be pending and whether criminal, immigration, residence, fraud, permanent-residence, security, or other substantive issues create litigation risk.
What if USCIS denies my N-400 after the delay?
Once USCIS issues a denial, the procedural framework changes. The applicant should evaluate administrative review through Form N-336 and, after exhaustion where applicable, federal district court review under 8 U.S.C. § 1421(c).
Governing Naturalization Delay Authority
Federal statutes, regulations, and current USCIS policy should be reviewed when evaluating jurisdiction in an individual delayed naturalization case.
Delay Can Create a Federal Remedy — But Strategy Comes First
Once 120 days have passed after the naturalization examination without a USCIS decision, the question is no longer simply how long the case has been pending. The applicant should determine whether federal court jurisdiction exists, why USCIS has not decided the N-400, and whether forcing adjudication is the right strategy.
