8 C.F.R. Part 335 • N-400 Examination • Naturalization Procedure

8 C.F.R. Part 335: Naturalization Examination Regulations

8 C.F.R. Part 335 contains the federal regulations governing the investigation and examination of Form N-400. The regulations address the scope of the naturalization interview, testimony under oath, attorneys, documentary evidence, witnesses, continuances, the 120-day decision period, use of the examination record after denial, derogatory information received before the oath, missed interviews, failure to prosecute, transfer of a pending application, and withdrawal.

Why Part 335 matters: INA § 335 supplies the statutory examination authority, while 8 C.F.R. Part 335 provides many of the procedural rules governing what USCIS actually does with an N-400 after filing. These regulations explain why the interview can examine every issue relating to eligibility, when USCIS may continue the case, what becomes part of the administrative record, and what occurs when the applicant misses an interview, fails to provide requested evidence, or seeks to withdraw the application.
Regulatory Roadmap

8 C.F.R. § 335.1

Investigation of the Naturalization Applicant

Part 335 begins with investigation rather than the interview itself. After Form N-400 is filed, USCIS investigates the applicant and reviews records relevant to naturalization eligibility.

The regulation describes review of pertinent records and other investigative activity. The regulatory language also refers to police checks and neighborhood investigation, while permitting waiver of the neighborhood-investigation component.

The Government's Review Can Begin Long Before the Interview

An applicant with a known criminal, immigration, marriage, fraud, residence, voting, citizenship-claim, or other serious issue should not assume that USCIS will learn about the matter only if the applicant raises it at the interview.

8 C.F.R. § 335.2

The Naturalization Examination

Section 335.2 is one of the most important procedural regulations in naturalization law.

It requires an applicant to appear personally before a designated USCIS officer and provides that the examination must encompass all factors relating to eligibility for naturalization.

The N-400 Interview Is Not Limited to English and Civics

The regulatory scope permits USCIS to examine lawful permanent residence, continuous residence, physical presence, criminal history, good moral character, marriage, tax issues, prior immigration statements, voting, citizenship claims, security questions, and any other issue relevant to the statutory basis for naturalization.

Criminal Background Check

FBI Background Check Before the Initial Examination

Section 335.2 contains a specific background-check requirement tied to scheduling the initial naturalization examination.

The regulation provides that USCIS will notify an applicant to appear for the initial examination only after receiving the specified definitive FBI response concerning completion of the full criminal background check.

A Criminal Record and a Naturalization Bar Are Not the Same Thing

The existence of an arrest or criminal record does not itself answer whether the applicant is eligible for citizenship. The exact offense, disposition, sentence, immigration classification, timing, good moral character consequences, and possible removability must be analyzed separately.

Examination Under Oath

The Applicant's Answers Become Evidence

Section 335.2 requires the applicant to be questioned under oath or affirmation in a setting apart from the public.

The officer may correct written N-400 answers so that the application conforms to the applicant's sworn oral statements.

Do Not Guess About a Material Historical Event

An applicant who cannot accurately remember an arrest, immigration filing, border encounter, prior marriage, trip, employment record, voter registration, or other significant event should not create a new sworn factual record through speculation.

Correcting an N-400 Answer Is Not Automatically Fraud

The regulation itself anticipates corrections during examination. Whether an inaccurate original answer creates a separate fraud, misrepresentation, or false-testimony issue depends on the facts and the governing legal elements.

Right to Representation

An Attorney or Accredited Representative May Attend

Section 335.2 expressly allows an applicant to request the presence of an attorney or representative who has properly entered an appearance.

The applicant remains the witness and must establish eligibility, but counsel can be particularly important where the interview involves a disputed criminal, immigration, marriage, fraud, residence, or other legal issue.

Applicant's Role

The applicant answers factual questions under oath and provides the testimony necessary to establish naturalization eligibility.

Counsel's Role

Counsel can identify the governing legal standard, present relevant evidence, address procedural issues, clarify the legal significance of the record, and help preserve disputed issues.

Evidence at Examination

Part 335 Provides for Oral and Documentary Evidence

Section 335.2 provides both USCIS and the applicant rights to present oral or documentary evidence necessary for a full and true disclosure of the facts.

The regulation also contemplates cross-examination where required by the circumstances.

Applicant Documents

Court records, immigration files, travel records, tax documents, marriage evidence, declarations, and other evidence may be presented when relevant.

Government Evidence

USCIS may rely on material available through the applicant's immigration record, investigation, background checks, and other relevant government sources.

Testimony

The applicant's sworn testimony and, where appropriate, testimony from other witnesses can become part of the administrative record.

Witnesses and Subpoenas

Part 335 Contains Formal Evidentiary Procedures

Witnesses may be questioned under oath concerning their credibility, knowledge of the applicant, and knowledge of the applicant's qualifications for naturalization.

Section 335.2 also establishes procedures for subpoenas requiring witness attendance or production of documentary evidence.

An Applicant May Request a Subpoena

A written subpoena request must identify the relevance, materiality, and scope of the requested testimony or documents and affirmatively show that the evidence cannot otherwise be produced. The examining officer must document a refusal to issue a requested subpoena in the record.

Record of Examination

What Becomes Part of the Naturalization Record?

Part 335 requires USCIS to maintain a record of the examination. Corrections to the application, supplemental material, evidence, testimony, and other examination materials can become part of the administrative record.

Corrected N-400

Corrections made during the examination are incorporated into the record.

Documentary Evidence

Evidence received by the officer is identified and placed into the record for adjudication.

Statements and Testimony

Depositions, statements, affidavits, transcripts, and other recorded testimony can become part of the file.

The Interview Record Matters if USCIS Later Denies the N-400

The administrative record does not disappear after denial. It can follow the case into the N-336 hearing and become important in any later federal court review.

Interpreter Use

Part 335 Also Addresses Authorized Interpreter Use

When an interpreter is authorized under the applicable naturalization rules, the examining officer records the interpreter's identity and use.

The regulation also permits a USCIS officer who is proficient in the applicant's native language to conduct the examination in that language with the applicant's consent.

8 C.F.R. § 335.3

Grant, Denial, or Continuance After the Initial Examination

Section 335.3 addresses what USCIS does after examining the applicant.

I

Grant

USCIS grants the N-400 if the applicant has satisfied all applicable requirements for naturalization.

II

Continue

USCIS may continue the initial examination for one reexamination to give the applicant an opportunity to overcome identified deficiencies.

III

Deny

If the applicant cannot establish the requirements for naturalization, USCIS may deny the application under the procedures governing naturalization denials.

120-Day Decision Period

Part 335 Ties the Decision Period to the Initial Examination

Section 335.3 provides for a grant or denial at the initial examination or within 120 days after the date of that initial examination.

USCIS's current Policy Manual likewise states that the agency has 120 days from the initial naturalization interview to issue a decision.

The 120 Days Do Not Run From the N-400 Filing Date

The specialized post-examination federal court remedy should not be confused with ordinary case-processing time. A delay before the initial examination presents a different procedural issue.

Continued Examination

USCIS May Continue the Case for One Reexamination

Rather than immediately deny the N-400, § 335.3 permits USCIS to continue the initial examination for one reexamination when the applicant may be able to overcome identified deficiencies.

01

USCIS Identifies the Problem

The officer must inform the applicant in writing of the grounds to be overcome or evidence that must be submitted.

02

Applicant Responds

The response should address the particular factual or legal deficiency identified by USCIS.

03

Reexamination Is Scheduled

The regulation generally prevents USCIS from requiring the applicant to appear for reexamination earlier than 60 days after the first examination.

04

USCIS Makes the Determination

If the applicant establishes eligibility, USCIS can approve the N-400. If the deficiencies are not overcome, USCIS can deny it.

8 C.F.R. § 335.4

The Examination Record Follows a Denied Case to N-336

Section 335.4 specifically addresses what happens to the examination record when USCIS denies Form N-400.

The corrected application, supplements, affidavits, transcripts, documents, and other evidence are submitted for use in the administrative hearing process under Part 336.

This Is Why the Initial Interview Record Matters So Much

An N-336 officer can review what occurred during the original examination. A factual concession, inconsistent sworn answer, missing document, or unresolved legal issue at the first interview can remain central during administrative review.

8 C.F.R. § 335.5

Derogatory Information Received After Approval but Before the Oath

Approval of the N-400 does not necessarily end USCIS's ability to address newly received adverse information before the applicant naturalizes.

Section 335.5 directs USCIS to remove an applicant from the list for oath administration when specific derogatory information arises after approval but before the oath.

01

USCIS Receives Derogatory Information

The information arrives after N-400 approval but before administration of the Oath of Allegiance.

02

Applicant Is Removed From the Oath Schedule

USCIS pauses oath administration while the new issue is resolved.

03

USCIS Gives Notice

The regulation provides for written notice of the specific derogatory information together with a motion to reopen the previously adjudicated application.

04

Applicant Has an Opportunity to Respond

Section 335.5 provides a 15-day response period.

Approval of Form N-400 Is Not the Same as Becoming a Citizen

Except where a statutory exception applies, naturalization is not complete until the applicant takes the Oath of Allegiance. A serious eligibility problem discovered before the oath can still affect the case.

8 C.F.R. § 335.6

Missing the Naturalization Examination

Section 335.6 governs failure to appear for the naturalization examination.

If the applicant misses the examination and fails to notify USCIS in writing of the reason and request rescheduling within 30 days, USCIS may administratively close the application without deciding the merits.

Request Reopening Within One Year

An administratively closed application may be reopened by written request within one year, without an additional filing fee under this regulation.

Failure to Reopen

If reopening is not requested within one year, USCIS treats the application as abandoned and dismisses it without further notice.

Reopening Can Affect the Eligibility Date

Section 335.6 provides that the date of the reopening request is treated as the filing date for purposes of determining naturalization eligibility.

8 C.F.R. § 335.7

Failure to Prosecute After the Initial Examination

A different regulation applies when the applicant attended the initial examination but later fails to pursue the case.

Failure without good cause to attend a subsequently required appearance or to provide documents, information, or testimony USCIS considers necessary to establish eligibility can constitute failure to prosecute.

USCIS Can Decide the N-400 on the Existing Record

Under § 335.7, if the applicant does not respond within the regulatory period following USCIS's notification, USCIS may adjudicate the application on its merits. That can produce a substantive denial rather than merely indefinite administrative closure.

8 C.F.R. § 335.9

Moving While Form N-400 Is Pending

Section 335.9 addresses transfer when an applicant changes residence or plans to change residence while the naturalization application is pending.

The applicant may submit a written request that the pending application be transferred to the USCIS office having jurisdiction over the new residence.

Transfer Is Not Automatically Granted

The regulation gives USCIS discretion concerning transfer. If USCIS does not consent and ultimately denies the N-400, the written decision must also address the reason for refusing the requested transfer.

8 C.F.R. § 335.10

Withdrawal of Form N-400

An applicant may request withdrawal of a pending naturalization application in writing.

The important point is that withdrawal requires USCIS consent.

USCIS Consents

The N-400 is denied without prejudice to a future application, and the withdrawal waives review under Part 336.

USCIS Does Not Consent

USCIS may proceed to adjudicate the naturalization application on its merits.

Withdrawal Is Not a Guaranteed Way to Stop USCIS From Deciding the Case

This can be particularly important where an applicant discovers a significant lawful permanent residence, fraud, criminal, or removability issue during the naturalization process. A withdrawal request does not by itself erase the underlying facts or require USCIS to disregard the pending case.

Statute and Regulations

How INA § 335, Part 335, and Part 336 Fit Together

AuthorityPrimary Function
INA § 335 / 8 U.S.C. § 1446 Supplies the statutory framework for investigation and examination of naturalization applicants.
8 C.F.R. Part 335 Provides detailed procedures for investigation, examination, evidence, continuances, decisions, missed interviews, transfer, and withdrawal.
INA § 336 / 8 U.S.C. § 1447 Establishes post-denial administrative review and the separate post-examination delay remedy.
8 C.F.R. Part 336 Provides the detailed regulatory framework for N-400 denials, N-336 hearings, and related judicial-review procedure.
When Part 335 Becomes Important

These Regulations Matter Most When the N-400 Process Stops Being Routine

Serious Interview Issue

USCIS begins questioning a historical immigration, criminal, marriage, fraud, travel, voting, or other problem.

Decision Cannot Be Made

The application is continued and USCIS requests additional evidence or requires reexamination.

Long Post-Interview Delay

The 120-day period becomes relevant after the initial naturalization examination.

N-400 Denial

The original examination record becomes relevant to an N-336 hearing.

New Information Before Oath

USCIS receives derogatory information after approving the application but before naturalization is complete.

Withdrawal Request

The applicant wants to withdraw after discovering a problem, but USCIS consent and the regulatory consequences must be considered.

Can I withdraw my N-400?

You may request withdrawal in writing, but § 335.10 requires USCIS consent. If USCIS does not consent, it may decide the application on its merits.

Does withdrawing N-400 erase an immigration problem USCIS discovered?

No. Withdrawal concerns the pending naturalization application. It does not erase the historical facts or independently eliminate a criminal, immigration, lawful-LPR, fraud, or removability issue.

Naturalization Interview & Procedural Problems

Has Your N-400 Been Continued, Delayed, Reexamined, or Placed at Risk After the Interview?

A naturalization case review can examine the interview record, USCIS's request for additional evidence, the Part 335 procedures, underlying eligibility issue, post-interview deadline, and available administrative or federal court remedies.
