Quick answer
What this page can help you verify
Form N-400 asks USCIS to determine whether a lawful permanent resident qualifies to naturalize. The filing is not only an English and civics test. USCIS reviews the basis and continuity of permanent residence, physical presence and continuous residence, jurisdiction, good moral character, attachment to constitutional principles, and the truthfulness of the complete immigration record. [1] [2] [3]
The review period for a particular requirement may not be the only history USCIS examines. Travel, taxes, arrests, citations, child support, selective service, prior marriages, and statements made in visa or green-card filings should be reconciled before the application is signed. Applicants who may already have acquired or derived citizenship should also verify whether N-400 is the correct form. [2] [3]
Use this naturalization guide to prepare records and questions about naturalization review. It provides general information, does not decide eligibility, and does not create an attorney-client relationship.
Decision map
Questions that control the analysis
For naturalization review, identify the legal branch before collecting documents. Begin with correct citizenship path, permanent residence, residence and travel; then match each unresolved point to a reliable record and the cited official instruction.
| Checkpoint | What to verify |
|---|---|
| Correct citizenship path | Confirm whether the person needs naturalization or may already be a citizen through a parent, birth rule, or another citizenship provision. [1] |
| Permanent residence | Review the original green-card basis, conditional-residence history, rescission or abandonment concerns, and the date used for eligibility. [2] |
| Residence and travel | Calculate continuous residence and physical presence from complete travel records and analyze long trips rather than relying on estimates. [3] |
| Good moral character | Review criminal events, taxes, support obligations, false statements, voting, selective service, and other conduct under the applicable rules. [4] |
| Testing and oath | Determine the English and civics test, any age-and-residence exception, disability accommodation or medical exception, and oath issues. [1] |
Process
A practical file-review sequence
- Confirm the correct eligibility provision, earliest filing date, state or district residence, and whether any pending I-751 or other case affects strategy. [2]
- Create a travel spreadsheet from passports, I-94 records, tickets, employment, tax, and address records; resolve discrepancies before filing. [3]
- Obtain certified court dispositions and tax records where relevant and compare the application with the person's complete immigration history. [4]
- File using current instructions, track biometrics or reused biometrics, and prepare for questions about the application, background, English, and civics requirements. [1]
- At the interview and oath stages, update material events truthfully and follow the notice instructions for documents, scheduling, and any requested response. [2]
Evidence plan
Records to organize before legal review
The evidence plan for naturalization review should connect the controlling facts to permanent residence, travel and residence, taxes and obligations. Volume alone does not prove that a filing, response, or defense satisfies the applicable rule.
- Permanent residence: Green cards, immigrant visa or adjustment approval, I-751 records, passports, and documents supporting the original admission.
- Travel and residence: All passports, I-94 history, travel log, leases, employment, school, tax, and family records showing residence over time.
- Taxes and obligations: IRS transcripts, payment plans, filing explanations, child-support records, and proof of resolving any outstanding issue.
- Criminal and civil events: Certified arrest and court records, probation completion, expungement records, citations, and a legal analysis where needed.
- Testing or exception: Study records, identification, disability-accommodation request, or properly completed medical-exception evidence when applicable.
Record control
Build a chronology that another professional can audit
For naturalization review, create one working table with five columns: date or period, event, document that proves it, unresolved conflict, and next action. Use exact dates from primary records where possible. Label estimates and record what would confirm them. Show conflicting records instead of silently choosing one before a signed filing or interview adopts that version.
For this guide, mark when each controlling issue began or changed: correct citizenship path, permanent residence, residence and travel, good moral character, testing and oath. [1] The purpose is to see sequence and legal posture, not to create a persuasive story before the facts are complete. A petition approval, departure, arrest, marriage, filing, denial, court order, employer change, or agency notice can alter the analysis from that date forward.
Link every important event to the most reliable available record. Organize the file under these evidence groups: permanent residence, travel and residence, taxes and obligations, criminal and civil events, testing or exception. Keep the original, a readable working copy, and any certified translation together. Record who created the document, when it was created, and whether the government has already received a different version.
For naturalization review, add a source-control row for each legal or procedural assumption: official page title, URL, date checked, and any case-specific notice or order that supersedes the general page. [4] Before acting, flag every conclusion that still depends on memory, an unofficial summary, an incomplete record, an old form, or an unanswered question for counsel.
Risk check
Common mistakes that can change the case
- Filing before calculating travel and continuous-residence consequences from reliable dates. [3]
- Assuming an expunged, dismissed, sealed, or old arrest need not be disclosed where the form requires it. [4]
- Treating the interview as only a civics test and failing to review the underlying green-card and immigration record. [1]
- Claiming an exception or disability waiver without using the current rule and required supporting form. [2]
- Submitting while an unresolved tax, support, voting, selective-service, criminal, or abandonment issue needs legal analysis. [3]
Consultation preparation
Questions to take to a qualified lawyer
A consultation about naturalization review is more useful when it begins with the controlling document, a dated chronology, and the complete prior record. Take the following questions and note where the lawyer's answer depends on missing evidence.
- Is N-400 the correct path, or might citizenship already have been acquired or derived?
- What eligibility provision and filing date apply, and does a pending I-751 affect processing?
- Do any trips threaten continuous residence or the required physical-presence total?
- Could the original permanent-residence grant, a criminal event, taxes, voting, or a prior statement create risk?
- Which English, civics, disability, military, or oath rules apply to this applicant?
