N-400 Attorney Fees — What Citizenship Applicants Pay
Filing fee for Form N-400 (naturalization application) has been $725 since April 2024. That part's non-negotiable. The wildcard is the n-400 attorney fees, which range from $500 for form-completion services to $3,500 for full representation through the naturalization interview and oath ceremony. The gap between those extremes isn't padding. It reflects scope of service, attorney experience in citizenship cases, and whether you're paying for document review only or for representation if USCIS schedules a second interview or flags your travel history. Most firms quote a flat fee, but what that fee includes varies dramatically.
Our team has worked with citizenship applicants across this spectrum for decades. The difference between a $700 flat fee and a $2,200 flat fee usually comes down to three things most online guides don't clarify until you're mid-process: whether interview preparation is included, whether the attorney shows up to the interview with you, and what happens if your case requires a response to a Request for Evidence or additional documentation after filing.
What do n-400 attorney fees actually cover?
N-400 attorney fees cover a defined scope of legal services associated with filing and pursuing U.S. citizenship through naturalization. The baseline service in most fee agreements is form completion and document review. The attorney ensures Form N-400 is accurate, complete, and supported by the required documentation (tax returns, travel records, selective service registration if applicable). At this baseline tier, fees typically range from $500 to $1,200. The higher end of that range includes attorney review of eligibility questions. Residency continuity, prior arrests or citations, tax filing compliance. That require judgment calls, not just data entry.
Full-scope representation adds interview preparation (one or more sessions walking through the civics test, English assessment, and likely questions about your application), attendance at the USCIS naturalization interview, and follow-up correspondence if USCIS issues a Request for Evidence (RFE) or Notice of Intent to Deny (NOID). This tier typically runs $1,800 to $3,500 depending on case complexity and geographic market. Cases involving prior immigration violations, criminal history (even dismissed charges require disclosure), extended international travel during the residency period, or discrepancies between USCIS records and your documentation push fees toward the higher end of that range.
Some firms structure fees as flat-rate packages with defined inclusions. Others use a la carte pricing. $800 for filing, $400 for interview prep, $600 for interview attendance. Neither model is inherently better, but the a la carte structure exposes you to cumulative costs if your case requires multiple services. The critical disclosure to confirm before signing a retainer agreement: does the quoted fee cover only services up to the interview, or does it include representation through the oath ceremony if delays or complications arise after the interview?
What N-400 Attorney Fees Include (And What They Don't)
N-400 attorney fees typically include: review of eligibility for naturalization under INA Section 316(a) or 319(a) (spouse of U.S. citizen); completion of Form N-400 based on client-provided information; compilation of supporting documentation (passport biographical pages, travel records, marriage certificates, tax transcripts); submission of the application package to USCIS; and one round of correspondence with USCIS if a deficiency notice is issued pre-interview. That's the baseline flat-fee package at most immigration law firms.
What baseline fees often exclude: attendance at the USCIS interview (which may be offered as an add-on at $400–$800), representation at a second interview if USCIS schedules one due to unresolved questions, filing of Form N-336 (appeal of denial) if the application is denied, and representation in removal proceedings if USCIS refers your case to an immigration judge. Those exclusions aren't fine print. They're explicitly listed in most retainer agreements. If your case involves any red flag. Criminal history, prolonged absences from the U.S., prior visa overstays, inconsistent tax filing. Confirm whether follow-up representation is included in the quoted n-400 attorney fees or billed separately.
Some firms include interview preparation as part of the base fee; others charge separately. Interview prep typically involves one 60-to-90-minute session reviewing the civics questions (100 possible questions, 10 asked at the interview, 6 correct answers required to pass), practicing the English reading and writing test, and walking through likely questions about your application. Employment history, marital status changes, reasons for international travel. The civics test itself is standardized, but the personal questions are case-specific. An attorney who has reviewed your full file can anticipate which parts of your history USCIS will probe.
Travel-heavy applicants. Those with cumulative absences exceeding 180 days in any 12-month period during the residency requirement. Benefit from attorney-prepared explanations of why those absences didn't disrupt residency continuity. USCIS interprets 'breaking continuity of residence' narrowly, but applicants often misstate the facts at the interview in ways that create problems. That's where attorney attendance at the interview justifies the cost. The attorney doesn't answer for you, but ensures you don't volunteer information that complicates the record.
How N-400 Attorney Fees Compare Across Service Models
N-400 attorney fees vary by service model: solo practitioners, mid-sized immigration firms, and nonprofit legal aid organizations each price differently because their cost structures and service scopes differ. Solo practitioners often charge $800 to $1,500 for full-service representation including interview attendance. Mid-sized firms typically charge $1,800 to $2,800 for comparable services due to higher overhead and multiple-attorney review. Nonprofit legal aid (for income-eligible applicants) may charge reduced fees or waive fees entirely, but eligibility thresholds are strict. Household income typically must be at or below 200% of federal poverty guidelines.
Online legal service platforms offer document preparation starting at $300 to $600, but this is not legal representation. The platform provides software-guided form completion. You input data, the platform generates a completed N-400 and a checklist of required supporting documents. No attorney reviews your answers for legal sufficiency. No one advises whether your travel history requires additional explanation or whether a prior arrest (even if dismissed) should be disclosed. For straightforward cases. Married to a U.S. citizen for three years, no criminal history, no extended absences, continuous tax filing. Document preparation platforms can suffice. For cases with any complexity, the lack of legal review is a meaningful gap.
Attorney experience level affects pricing. An attorney who has handled 500+ naturalization cases and regularly appears at the local USCIS field office charges more than a general practice attorney handling occasional immigration matters. That experience translates into familiarity with how the local USCIS office interprets ambiguous residency issues, which documentation they routinely request in RFEs, and which explanations satisfy officers at the interview. Paying $2,200 instead of $900 for that institutional knowledge is justified if your case involves judgment calls. But not if your case is procedurally routine.
| Service Model | Typical Fee Range | Services Included | Interview Attendance | Best For |
|---|---|---|---|---|
| Solo Practitioner | $800–$1,500 | Form completion, document review, eligibility assessment, interview prep | Usually included | Applicants with moderately complex cases or those who want full representation at lower cost |
| Mid-sized Firm | $1,800–$2,800 | Form completion, document review, multiple-attorney oversight, interview prep, interview attendance | Included | High-complexity cases (criminal history, prior denials, extended absences) |
| Online Platform | $300–$600 | Software-guided form completion, document checklist | Not included | Straightforward cases with no legal ambiguity |
| Nonprofit Legal Aid | $0–$500 (income-based) | Full representation for eligible applicants | Included for eligible cases | Low-income applicants who meet income thresholds |
| Professional Recommendation | If your case involves criminal history, tax issues, or residency gaps, mid-sized firm or experienced solo practitioner is the better investment; online platforms are suitable only for applicants with zero red flags |

What If: N-400 Attorney Fee Scenarios
What If I Have a Prior Arrest That Was Dismissed?
Retain an attorney even if charges were dismissed. USCIS requires disclosure of all arrests regardless of disposition, and the way you explain the arrest at the interview determines whether it becomes a denial issue. An attorney reviews the arrest records, prepares a written explanation for your file, and ensures your verbal answer at the interview matches the documented facts. Cost typically adds $300–$600 to baseline n-400 attorney fees, but prevents the denial risk that comes from incomplete or inconsistent disclosure.
What If I've Been Out of the Country for Extended Periods?
Absences totaling more than six months in a single trip trigger closer scrutiny of whether you maintained residency continuity. USCIS interprets this through INA Section 316(b), which presumes that absences over six months break continuity unless you can prove otherwise through employment records, lease agreements, tax filings, and family ties. Attorney-prepared documentation packages demonstrating continuous ties to the U.S. are critical here. This level of case complexity typically requires $1,800–$2,500 in attorney fees because the attorney must compile and present evidence beyond standard N-400 documentation.
What If I Filed Taxes Late or Owe Back Taxes?
Late tax filing doesn't disqualify you, but you must disclose it and provide IRS transcripts showing filing history and any outstanding balances. USCIS doesn't require that you've paid all taxes owed, but they assess whether you're in 'good moral character'. Willful tax evasion is disqualifying; late filing due to oversight typically isn't. An attorney structures your explanation to distinguish between the two. Expect this to add $400–$800 to n-400 attorney fees because it requires IRS transcript review and written explanation for your USCIS file.
The Unvarnished Truth About N-400 Attorney Fees
Here's the honest answer: most N-400 applicants don't need an attorney if their case is procedurally clean. Three or five years of continuous residence, no arrests, no extended travel, no gaps in tax filing. USCIS designed Form N-400 to be completable by applicants without legal help, and the naturalization interview is standardized. If you can answer 'no' to every question in Part 12 (information about you) without hesitation, the marginal value of paying $1,500 in n-400 attorney fees is low.
But if you hesitate on even one question in Part 12. If you've ever been arrested, cited, detained, or charged with any offense (even if dismissed); if you've taken trips longer than six months; if you've filed taxes late or had years where you didn't file; if your marriage to a U.S. citizen has ended and you're filing under the three-year rule. The cost of getting it wrong exceeds the cost of hiring representation. A denied N-400 costs $725 in non-refundable filing fees plus the opportunity cost of delayed citizenship. Hiring an attorney for $1,200 to prevent that outcome is a net gain. The calculation isn't whether an attorney improves your odds if everything is straightforward. It's whether an attorney prevents a denial if anything is ambiguous.
The application is where most self-represented applicants make mistakes. They omit arrests they think don't count. They miscalculate the residency period. They list travel dates from memory instead of pulling passport stamps. USCIS cross-references your N-400 against their records from prior visa applications, entry/exit data, and any prior immigration proceedings. Inconsistencies trigger RFEs or denials. An attorney reviews those records before filing to ensure alignment. That's the service you're paying for. Not hand-holding through a simple form, but professional judgment on how USCIS will interpret your specific history.
N-400 attorney fees are steep for cases requiring minimal legal analysis. They're justified for cases where the law requires interpretation of your specific facts. And that's most cases involving anything beyond five years of clean residency, continuous employment, and zero legal issues. The firms charging $3,000+ are pricing for high-complexity cases with litigation risk. The firms charging $700 are pricing for volume form-completion. Neither is overcharging. They're serving different case profiles. Your responsibility is to accurately assess which profile matches your case. Misjudging that costs more than the attorney fee you were trying to avoid.

Frequently Asked Questions
How much do attorneys typically charge for N-400 application assistance? ▼
Attorneys typically charge between $800 and $2,500 for N-400 application assistance, with the range depending on whether the fee covers only form preparation and document review ($800–$1,200) or includes interview preparation and attendance ($1,800–$2,500). Cases involving criminal history, extended absences, or prior immigration issues push fees toward the higher end of that range due to increased documentation and legal analysis required.
Can I file Form N-400 without hiring an attorney? ▼
Yes, you can file Form N-400 without an attorney if your case involves no legal complications — continuous residence with no absences exceeding six months, no criminal history, no tax filing gaps, and straightforward eligibility under INA Section 316(a) or 319(a). USCIS designed the form to be self-completable for routine cases. However, any ambiguity in your history — arrests (even dismissed), extended travel, late tax filings, or prior visa violations — increases the risk that self-filing will result in a Request for Evidence or denial.
What is included in a typical N-400 flat-fee attorney package? ▼
A typical flat-fee package includes completion of Form N-400, review of eligibility under applicable Immigration and Nationality Act sections, compilation of required supporting documents (tax transcripts, travel records, passport copies), submission of the application to USCIS, and one round of correspondence if USCIS issues a deficiency notice before the interview. Interview attendance is sometimes included, sometimes charged separately — confirm this explicitly before signing a retainer agreement.
What are the risks of using an online document preparation service instead of an attorney for N-400? ▼
Online document preparation services provide software-guided form completion but no legal review of your answers. The primary risk is that you'll answer eligibility questions incorrectly without realizing the legal consequences — for example, failing to disclose a dismissed arrest, miscalculating the continuous residence period, or omitting international travel that breaks residency continuity. USCIS cross-references your N-400 against prior immigration records, and inconsistencies trigger delays or denials. For cases with any legal complexity, the cost of a denied application ($725 non-refundable filing fee plus citizenship delay) exceeds the cost of hiring an attorney.
How do N-400 attorney fees compare between solo practitioners and larger immigration firms? ▼
Solo practitioners typically charge $800–$1,500 for full N-400 representation including interview attendance, while mid-sized firms charge $1,800–$2,800 for comparable services. The difference reflects overhead costs (larger firms have multiple staff reviewing cases) rather than quality of legal work. Solo practitioners with extensive naturalization experience often provide the same level of representation at lower cost because they have lower operating expenses. The key variable is the attorney's specific experience with N-400 cases, not firm size.
Does hiring an attorney guarantee my N-400 application will be approved? ▼
No attorney can guarantee approval because USCIS makes the final eligibility determination based on statutory requirements under the Immigration and Nationality Act. What an attorney guarantees is that your application is legally accurate, complete, and supported by the documentation USCIS requires — and that you're prepared to answer interview questions in a way that doesn't create unnecessary complications. Attorneys reduce the risk of denial due to procedural errors, incomplete disclosure, or misstatement of facts, but they cannot override substantive ineligibility (failure to meet residency requirements, criminal inadmissibility, lack of good moral character).
What should I ask an attorney before paying N-400 attorney fees? ▼
Ask: (1) Does the quoted fee include interview attendance, or is that billed separately? (2) What happens if USCIS issues a Request for Evidence after filing — is that covered or an additional charge? (3) How many N-400 cases has the attorney personally handled, and what percentage resulted in approval without appeal? (4) If my application is denied, does the fee include filing Form N-336 (appeal), or is that a separate matter? (5) Will you personally handle my case, or will it be delegated to paralegals or associates? These questions clarify scope and avoid surprise charges mid-process.
When do complications in an N-400 case justify paying higher attorney fees? ▼
Higher attorney fees ($2,000+) are justified when your case involves: any arrest or criminal charge (even if dismissed or expunged), absences from the U.S. exceeding six months during the statutory residency period, gaps in tax filing or unfiled returns, prior immigration violations (visa overstays, unlawful presence, prior removal orders), or inconsistencies between your current application and prior USCIS filings. These issues require legal analysis, documentation packages beyond standard N-400 requirements, and attorney representation at the interview to prevent misstatements that lead to denial.
Are nonprofit legal aid organizations a good option for N-400 assistance? ▼
Nonprofit legal aid organizations provide high-quality N-400 representation at reduced cost or no cost for income-eligible applicants, typically those at or below 200% of federal poverty guidelines. Services are comparable to private firms — form preparation, document review, interview prep, and interview attendance. The limitation is eligibility: if your household income exceeds the threshold, you won't qualify. For applicants who do qualify, nonprofit representation is an excellent option that doesn't sacrifice quality for cost.
What happens if I pay N-400 attorney fees but then decide to withdraw my application? ▼
Retainer agreements typically specify that fees are earned upon completion of defined services — form preparation, document compilation, and submission to USCIS. If you withdraw your application after the attorney has completed those services, you generally will not receive a refund. Some firms refund fees if you withdraw before filing, minus a processing charge for work already completed. Review the refund policy in the retainer agreement before signing. The $725 USCIS filing fee is non-refundable once submitted regardless of whether you withdraw.
