INA § 335: Naturalization Examination, Interview, and USCIS Investigation

INA § 335 • 8 U.S.C. § 1446 • Naturalization Examination

INA § 335: Naturalization Examination, Interview, and USCIS Investigation

INA § 335 provides the statutory framework for investigation and examination of naturalization applicants. Together with 8 C.F.R. Part 335, it explains why the N-400 interview can address much more than English and civics. USCIS may examine the applicant under oath, review the complete eligibility history, receive documentary and oral evidence, question witnesses, investigate relevant records, and decide whether every legal requirement for naturalization has been established.

In practical terms: the N-400 interview is a legal examination under oath, not merely a citizenship test appointment. The governing regulations require the examination to encompass all factors relating to naturalization eligibility. USCIS may review the application, prior immigration history, criminal history, residence, travel, marriage, taxes, good moral character, prior statements, English and civics eligibility, and other facts relevant to the statutory basis for naturalization.
Investigation and Examination

What Does INA § 335 Govern?

INA § 335, codified principally at 8 U.S.C. § 1446, governs the investigation and examination that occur before an applicant is naturalized.

The statute authorizes designated immigration officers to take testimony concerning matters affecting eligibility, administer oaths, require relevant evidence, and use subpoena procedures where legally appropriate.

Federal regulations in 8 C.F.R. Part 335 provide additional detail concerning investigation, the examination, continuances, reexamination, failure to appear, withdrawal, transfer, and the evidentiary record.

The Examination Covers All Factors Relating to Naturalization Eligibility

8 C.F.R. § 335.2 provides that the examination is to be uniform throughout the United States and encompass all factors relating to the applicant's eligibility for naturalization.

That broad scope is why USCIS can revisit matters that may have first arisen years before the N-400 was filed.

8 C.F.R. § 335.1

USCIS Investigation Before Naturalization

After an application for naturalization is filed, federal regulations provide for investigation of the applicant.

The regulatory framework includes review of pertinent records and background information relevant to eligibility.

I

Immigration Records

USCIS can compare the N-400 with prior applications, petitions, adjustment records, immigrant visa history, removal proceedings, and other immigration records relevant to eligibility.

II

Criminal and Security Checks

Naturalization processing includes required background and security screening. Criminal records can affect both good moral character and other immigration consequences.

III

Other Pertinent Records

Depending on the issue, USCIS may consider records bearing on residence, marriage, taxes, identity, immigration compliance, organizational history, or another naturalization requirement.

The Interview Is Not the Beginning of USCIS's Review

USCIS may already possess substantial historical information before the applicant appears for examination. An applicant with a known problem should therefore understand the existing immigration record before relying on the interview as the first opportunity to investigate what USCIS may know.

Background and Security Checks

Criminal Background Review Is Part of the Examination Process

8 C.F.R. § 335.2 requires USCIS to obtain the specified FBI criminal background-check response before scheduling the initial naturalization examination.

USCIS policy separately addresses fingerprints, FBI checks, and other background and security screening performed in naturalization cases.

Disclosure on the N-400 Should Match the Actual Criminal Record

An applicant should not assume that a dismissed, sealed, expunged, old, foreign, or otherwise unusual criminal matter can simply be omitted. The disclosure question and the immigration consequence of the event are separate issues.

Personal Examination

The Applicant Appears Before a USCIS Officer

The regulations generally require a naturalization applicant to appear personally before an officer designated to conduct the examination.

The examination occurs in a setting apart from the public, and the applicant is questioned under oath or affirmation.

Identity

USCIS confirms the applicant's identity and reviews information necessary to establish who is seeking naturalization.

N-400 Answers

The officer reviews the application and can question the applicant about answers, omissions, corrections, and facts relevant to eligibility.

Eligibility Evidence

The examination can address documents and testimony supporting or undermining any substantive naturalization requirement.

Testimony Under Oath

Why Does the Officer Place the Applicant Under Oath?

The examination is an evidentiary proceeding. The applicant's answers become part of the naturalization record.

The regulation authorizes USCIS to question the applicant under oath or affirmation and to correct written answers on the N-400 so that the application conforms to the applicant's sworn statements during the examination.

A Casual Answer Can Have Legal Consequences

Applicants should not guess about an old arrest, trip, immigration filing, marriage, employment history, voter record, citizenship claim, or other material event merely because they feel pressure to answer immediately. A sworn naturalization interview can create a new evidentiary record.

False Testimony Is a Distinct Naturalization Issue

Deliberately giving false oral testimony under oath for the purpose of obtaining an immigration benefit can raise a separate good moral character issue. That legal concept should not be confused with every mistake, inconsistency, or inaccurate written answer.

Corrections at the Interview

Can the N-400 Be Corrected During the Examination?

Yes.

8 C.F.R. § 335.2 expressly contemplates correction of written answers in the naturalization application to conform to the applicant's oral statements under oath.

The fact that an answer requires correction does not automatically mean the original application was fraudulent. The reason for the discrepancy, materiality, applicant's knowledge, and surrounding facts may matter.

Corrections Become Part of the Examination Record

At the conclusion of the examination, the regulations provide for corrections and supplemental material to be incorporated into the record, with the application and evidence certified under the applicable oath or affirmation.

Representation

Can an Attorney Attend the Naturalization Examination?

Yes. The examination regulation expressly permits an applicant to request the presence of an attorney or accredited representative who has properly entered an appearance.

Counsel does not replace the applicant as the witness. The applicant must answer the officer's questions and establish eligibility.

The Applicant Gives the Testimony

Naturalization eligibility depends on the applicant's own sworn answers and documentary record. Counsel ordinarily cannot answer factual questions in the applicant's place.

Counsel Can Protect the Legal Record

In a difficult case, counsel can help identify the legal issue, present relevant evidence, address misunderstandings, and preserve the distinction between facts, allegations, and legal conclusions.

English and Civics

The Naturalization Test Is Only Part of the Examination

The officer also administers the applicable English and civics testing unless the applicant qualifies for an exception or accommodation under the governing law.

Passing English and civics does not establish the other requirements for naturalization.

Educational Requirements

English and civics are governed principally by separate statutory and regulatory provisions, including INA § 312.

Substantive Eligibility

The same interview can also examine lawful permanent residence, residence, physical presence, good moral character, marriage, immigration history, and other issues.

Documentary and Oral Evidence

What Evidence Can Be Considered at the Examination?

The regulations contemplate both oral and documentary evidence. Evidence received by the officer becomes part of the naturalization record.

Government Records

USCIS may review its own immigration files and other pertinent government records available to the agency.

Applicant's Documents

The applicant may present records supporting residence, travel, marriage, criminal disposition, taxes, good moral character, or another disputed eligibility issue.

Testimony and Witnesses

The regulatory framework allows testimony from the applicant and, where relevant, witnesses whose knowledge bears on the naturalization issue.

Witnesses and Subpoenas

INA § 335 Gives the Examination Formal Evidentiary Tools

The statutory and regulatory framework authorizes testimony from witnesses and, in appropriate circumstances, subpoenas requiring attendance or production of documentary evidence.

An applicant or representative may also make a written request for a subpoena under the regulatory procedure, but the request must explain the relevance, materiality, and scope of the evidence and establish why it cannot otherwise be produced.

Most N-400 Cases Do Not Require Formal Subpoena Practice

The existence of subpoena authority demonstrates the formal scope of the examination. Whether that authority is useful in an individual case depends on the particular disputed evidence and procedural posture.

The Administrative Record

The Examination Creates the Record for Later Review

USCIS maintains a record of the naturalization examination. The regulations address notations regarding the examination, testing, corrected application, supplemental material, testimony, documentary evidence, and other material introduced into the case.

This becomes especially important if USCIS later denies the N-400.

The Examination Record Follows the Case to N-336 Review

8 C.F.R. § 335.4 specifically provides for use of the examination record in the administrative hearing process after a denial.

Statements and evidence created during the initial N-400 examination can therefore remain important well beyond the interview itself.

8 C.F.R. § 335.3

What Happens if USCIS Cannot Approve the N-400 at the First Interview?

USCIS does not necessarily have to grant or deny the N-400 immediately at the first examination.

The regulation permits USCIS to continue the initial examination for one reexamination so that the applicant has an opportunity to overcome identified deficiencies.

01

USCIS Identifies the Deficiency

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

02

Applicant Provides Evidence or Prepares for Reexamination

The response should address the actual legal or evidentiary deficiency rather than merely resubmit unrelated documents.

03

USCIS Conducts the Reexamination if Required

The regulation provides timing rules for a continued case, including that the applicant generally cannot be required to appear for reexamination earlier than 60 days after the first examination.

04

USCIS Makes a Determination

If the deficiencies are overcome, the application can be approved. If the applicant cannot establish eligibility, USCIS may deny the application.

The 120-Day Period

How Long Does USCIS Have After the Initial Examination?

8 C.F.R. § 335.3 provides that USCIS should make a decision to grant or deny the naturalization application at the initial examination or within 120 days after the date of that initial examination.

Federal law also provides a separate district court remedy when USCIS fails to make a naturalization determination within the statutory 120-day period after the examination described in INA § 335.

The 120-Day Remedy Is Different From Ordinary Processing Delay

The specialized federal court remedy under 8 U.S.C. § 1447(b) depends on the examination and statutory timing requirements. A case that has not yet reached the relevant examination stage presents a different legal posture.

Examination Outcomes

What Can Happen After the Naturalization Examination?

I

Approval

If USCIS determines that the applicant has satisfied the applicable requirements, the N-400 can be approved and the case proceeds toward administration of the Oath of Allegiance.

II

Continued Examination

USCIS may identify missing evidence, testing deficiencies, or another eligibility issue that must be resolved before a final determination.

III

Denial

If the applicant fails to establish eligibility, USCIS may issue a written denial that can trigger the administrative N-336 hearing process.

Approval Is Not Yet Citizenship

What if USCIS Receives Derogatory Information After N-400 Approval but Before the Oath?

The examination regulations specifically address this situation.

If USCIS receives derogatory information after approving an application but before the applicant has taken the Oath of Allegiance, the agency can remove the applicant from the oath schedule while the matter is resolved.

The regulation provides a procedure involving notice of the specific derogatory information and an opportunity to respond before the previously granted application is reopened and potentially denied.

N-400 Approval and Naturalization Are Not the Same Event

Except where a statutory exception applies, citizenship is completed through administration of the Oath of Allegiance. Significant new information arising after approval but before the oath can therefore still affect the case.

Failure to Appear

What Happens if an Applicant Misses the Naturalization Examination?

The regulations provide specific consequences when an applicant fails to appear.

If the applicant fails to appear and does not notify USCIS in writing of the reason and request rescheduling within the regulatory period, USCIS may administratively close the application without deciding the merits.

An Administratively Closed Application May Be Reopened

Current 8 C.F.R. § 335.6 provides a one-year period for requesting reopening of an administratively closed application. If reopening is not requested within that period, USCIS considers the application abandoned and dismisses it.

Failure to Prosecute

Ignoring a Post-Interview Request Can Also Damage the Case

After appearing for the initial examination, an applicant can still fail to prosecute the application by failing without good cause to attend a later required appearance or provide requested documents, information, or testimony needed to establish eligibility.

The regulation allows USCIS to adjudicate the application on the merits when the applicant fails to respond as required.

A Continued N-400 Should Not Be Left Unanswered

When USCIS identifies an unresolved issue after examination, the applicant should determine precisely what evidence or legal question must be addressed and respond within the applicable deadline.

Withdrawal of Form N-400

Can an Applicant Withdraw a Naturalization Application?

An applicant may submit a written request to withdraw Form N-400, but withdrawal is not automatically effective merely because the applicant asks.

Under 8 C.F.R. § 335.10, if USCIS consents to withdrawal, the application is denied without prejudice to a future application. The withdrawal also waives review under the N-336 hearing regulations.

If USCIS does not consent, it may adjudicate the N-400 on the merits.

Withdrawal Is Not a Guaranteed Escape From an Eligibility Problem

An applicant who discovers a serious issue during naturalization should not assume that simply requesting withdrawal eliminates the underlying immigration problem or prevents USCIS from addressing the pending application.

Scope of Questioning

Issues USCIS May Examine in a Difficult N-400 Case

IssueWhy It May Be Relevant at the INA § 335 Examination
Original green card Naturalization generally requires lawful admission for permanent residence.
Criminal history Criminal conduct may affect good moral character and, in some cases, broader immigration status.
Prior immigration statements USCIS may compare the N-400 with earlier visa, adjustment, petition, asylum, or other immigration records.
Marriage history Marriage may affect the naturalization basis, lawful permanent residence, marital union, or prior fraud concerns.
Travel and residence Travel can affect continuous residence, physical presence, and in some cases maintenance of permanent residence.
Taxes Tax compliance may affect good moral character, while certain nonresident tax positions can raise separate residence issues.
Voting or voter registration These facts may implicate good moral character, unlawful voting provisions, citizenship claims, or removability.
False claim to U.S. citizenship A qualifying claim can create consequences extending beyond the naturalization application itself.
English and civics Unless an exception applies, the applicant must establish the educational requirements of naturalization.
Preparing for a Difficult Examination

What Should Be Reviewed Before the N-400 Interview?

01

Review the Filed N-400

The applicant should know exactly what was submitted and identify any answer that requires correction or clarification before the officer asks about it.

02

Compare Prior Immigration Filings

Where a material historical issue exists, compare the N-400 with the prior government record rather than relying solely on memory.

03

Obtain Criminal Records

Bring the required dispositions and understand the immigration significance of the actual offense and disposition.

04

Reconstruct Travel and Residence

Make sure departure dates, return dates, addresses, employment, and residence evidence are internally consistent.

05

Identify the Legal Issue

If the case is complicated, determine in advance whether the concern involves good moral character, lawful LPR admission, residence, marriage, criminal law, fraud, voting, or another statutory requirement.

06

Prepare the Relevant Evidence

Evidence should address the disputed requirement directly rather than overwhelm the record with documents unrelated to the issue.

Frequently Asked Questions

INA § 335 and the N-400 Examination

What is INA § 335?

INA § 335 is the statutory framework governing investigation and examination of naturalization applicants and is codified principally at 8 U.S.C. § 1446.

Is the N-400 interview just the citizenship test?

No. Federal regulations state that the examination encompasses all factors relating to the applicant's naturalization eligibility. English and civics testing are only part of the process.

Is the applicant under oath at the naturalization interview?

Yes. The examination regulation provides for questioning under oath or affirmation.

Can USCIS correct answers on my N-400 during the interview?

Yes. The regulation expressly permits the examining officer to correct written answers to conform to the applicant's sworn oral statements.

Does correcting an answer mean I committed fraud?

No. A correction is not automatically fraud. The reason for the original error, applicant's knowledge, materiality, and other facts determine whether a separate misrepresentation issue exists.

Can USCIS ask about something that happened more than five years ago?

Potentially. Older facts can remain relevant to lawful permanent residence, current good moral character in appropriate circumstances, prior immigration representations, and other naturalization requirements.

Can USCIS review how I obtained my green card?

Yes. Lawful admission for permanent residence is generally a naturalization requirement, so the original adjustment or immigrant admission can be relevant to the N-400 examination.

Can an attorney attend the N-400 interview?

Yes. 8 C.F.R. § 335.2 permits an applicant to request the presence of a properly appearing attorney or representative.

Can USCIS call witnesses?

Yes. The statutory and regulatory framework permits examination of witnesses where their testimony is relevant to the applicant's qualifications.

Does USCIS have subpoena power in a naturalization examination?

INA § 335 and 8 C.F.R. § 335.2 contain subpoena procedures for relevant witnesses and documentary evidence in appropriate cases.

What happens if USCIS needs more evidence after the interview?

The examination may be continued. The regulations provide for one reexamination and require USCIS to identify in writing the grounds to be overcome or evidence that must be submitted.

Can USCIS conduct a second naturalization interview?

Yes. 8 C.F.R. § 335.3 provides for one reexamination of a continued application to permit the applicant to overcome identified deficiencies.

How long does USCIS have to decide after the examination?

The regulations provide for a decision at the initial examination or within 120 days after that examination. Federal law provides a specialized district court remedy when the statutory post- examination period expires without a determination.

What if I miss the naturalization interview?

Failure to appear without timely written notice and a request to reschedule can result in administrative closure. Current regulations provide a limited period to request reopening before the application is treated as abandoned.

Can I withdraw my N-400 after the interview?

An applicant may request withdrawal in writing, but USCIS must consent. If USCIS declines, it can adjudicate the application on its merits.

What happens if USCIS denies the N-400 after examination?

The applicant generally may request an administrative hearing by filing Form N-336 within the applicable deadline. The examination record becomes part of that later review.

Can USCIS reopen an approved N-400 before the oath?

The regulations contain a procedure for addressing derogatory information received after approval but before administration of the Oath of Allegiance.

N-400 Interview & Examination Problems

Has USCIS Raised a Serious Issue at Your Naturalization Interview?

A naturalization case review can examine the filed N-400, prior immigration records, interview testimony, criminal history, marriage or residence concerns, USCIS requests for evidence, the legal standard governing the disputed issue, and the record that may later control an N-336 hearing or federal court case.
