Citizenship Cost Calculator — US Naturalization Fees (2025)

Breaking Down the N-400 Filing Fee

The Form N-400 (Application for Naturalization) is the primary form you file to become a US citizen. As of 2025, USCIS charges $710 for paper filing or $640 for online filing. This fee includes the biometrics services fee, which was previously charged separately at $85. The reduced online fee reflects USCIS's push toward digital processing, which saves them administrative costs.

For applicants aged 75 and older, the biometrics fee is waived, though the base application fee still applies. Military applicants filing under sections 328 or 329 of the INA pay no filing fee at all — one of the benefits of military service that many veterans don't realize they qualify for.

It's important to note that USCIS periodically adjusts its fees. The last major fee increase was in April 2024, when the N-400 fee jumped from $640 (paper) to $710. Always verify current fees on the USCIS website before filing, as using the calculator with outdated information could lead to underpayment and application rejection.

Attorney Fees: When You Need Legal Help

Not every naturalization applicant needs an attorney. If you have a straightforward case — continuous residence, no criminal history, basic English proficiency, and a clean immigration record — you can file the N-400 yourself. USCIS provides detailed instructions, and many community organizations offer free assistance.

However, attorney representation is strongly recommended if: you have any criminal arrests or convictions (even dismissed charges), there are gaps in your residency or physical presence, you've had any immigration violations, you traveled outside the US for extended periods, or your green card was obtained through a complex process. Immigration attorneys typically charge $800–$1,500 for straightforward naturalization cases and $1,500–$3,000+ for complex cases involving criminal history or residency issues.

When selecting an attorney, verify they're licensed to practice immigration law. Check with your state bar association and look for attorneys who are members of the American Immigration Lawyers Association (AILA). Avoid notarios and unlicensed practitioners — they cannot legally represent you and their mistakes can jeopardize your application.

Hidden Costs Most Applicants Forget

Beyond the filing fee and optional attorney, several additional costs catch applicants off guard. Passport photos for the application cost $10–$20 at pharmacies or photo shops. If you may want to obtain copies of court records (for any arrests), costs range from $5–$50 per record. Translation and notarization of foreign documents can run $20–$50 per page. Citizenship test preparation courses range from free (through libraries and community colleges) to $100–$300 for commercial courses.

After naturalization, you'll likely want a US passport immediately. The passport application fee is $130 for a passport book (add $30 for a passport card). Expedited processing adds another $60. Include $35 for the execution fee if it's your first passport. Total passport costs: $165–$255 depending on options and speed.

Travel costs to USCIS offices for the biometrics appointment and interview vary widely based on your location. Urban applicants might spend $10 on transit; rural applicants could face $100+ in gas and potentially a hotel stay if the nearest USCIS office is hours away. Don't forget lost wages for taking time off work for these appointments — typically a half day for biometrics and a full day for the interview.

Fee Waivers: How to Apply for Free

USCIS offers a fee waiver (Form I-912) for applicants who demonstrate financial hardship. You qualify if: you're receiving a means-tested benefit (Medicaid, SNAP, SSI, TANF), your household income is at or below 150% of the federal poverty guidelines, or you're experiencing financial hardship due to extraordinary expenses. For a single-person household in 2025, 150% of the poverty line is approximately $22,590.

The fee waiver covers the entire N-400 filing fee. Approval rates for fee waivers are generally high when proper documentation is submitted. Required evidence includes benefit award letters, tax returns, pay stubs, or a detailed hardship letter with supporting documentation. Processing of the fee waiver request adds 2–4 weeks to your overall timeline.

Note that fee waiver approval for the N-400 does not guarantee fee waivers for future applications (like passport fees, which are handled by the State Department, not USCIS). Plan your budget accordingly.

Step-by-Step Timeline

The naturalization process follows a predictable sequence, but the time between steps varies significantly based on your USCIS field office, application volume, and case complexity. Here's what to expect at each stage with realistic 2025 timelines.

Step 1: Filing the N-400 (Day 1). You submit your application online or by mail. Online filing gets a receipt notice within 1–3 days. Mail filing takes 2–3 weeks to receive your receipt notice (Form I-797C). This receipt is important — it contains your case number for tracking and serves as proof that your application is pending. Keep it safe.

Step 2: Biometrics Appointment (Weeks 2–8). USCIS schedules your biometrics (fingerprinting) appointment at a local Application Support Center (ASC). The appointment itself takes 15–30 minutes. You'll have your fingerprints, photo, and signature captured digitally. These are used for FBI background checks. If you miss your appointment, you can request a reschedule, but this adds 4–8 weeks to your timeline. Since 2024, some applicants are having biometrics reused from previous applications, skipping this step entirely.

Step 3: Background Checks (Concurrent, 1–6 months). FBI name checks and fingerprint checks run concurrently with your application review. Most clear within 2–4 weeks. Complex cases (common names, any criminal history, extensive travel to certain countries) can take months. USCIS cannot schedule your interview until background checks clear, and there's no way to expedite this step.

The Interview: What to Expect

Step 4: Interview Scheduling (Months 4–14). This is the longest wait for most applicants. USCIS schedules interviews based on field office capacity, and backlogs vary enormously. Miami, New York, and Los Angeles often have 10–14 month waits. Smaller offices in the Midwest might schedule you in 4–6 months. You'll receive a notice (Form I-797C) with your interview date, time, and location at least 2 weeks in advance.

The interview itself typically lasts 15–30 minutes. A USCIS officer reviews your application, verifies your identity, administers the English language test (reading, writing, and speaking), and gives you the civics test (6 out of 10 questions correct from a pool of 100). The officer will also ask about any changes since you filed — new arrests, trips abroad, address changes, or marital status changes. Answer honestly; lying to a USCIS officer is a federal crime and grounds for denial.

Most applicants receive a decision at the end of the interview. Approved cases may be scheduled for a same-day oath ceremony (increasingly common at many offices) or scheduled for a later ceremony within 2–6 weeks. Some cases are"continued" (N-652 with a"Decision cannot be made" checkbox) if the officer needs additional evidence or the background check needs updating.

Common Delays and How to Avoid Them

The most common cause of delays is incomplete applications. Missing signatures, incorrect fees, outdated photos, or unanswered questions trigger Requests for Evidence (RFE) that add 2–4 months. Review your application thoroughly before filing — or have an attorney review it. The $200 you spend on a document review could save months of delays.

Travel outside the US while your application is pending is allowed but needs careful timing. If your interview notice arrives while you're abroad, you might miss the appointment. USCIS allows one reschedule, but it pushes you to the back of the interview queue. Check your mail (or set up USCIS online account notifications) regularly.

Address changes must be reported to USCIS within 10 days using Form AR-11. If USCIS sends your interview notice to an old address and you miss the appointment, your application can be administratively closed. Update your address proactively through your USCIS online account.

If your application has been pending for more than the posted processing time for your field office, you can submit a case inquiry through the USCIS Contact Center or request a case hearing with an immigration judge. An attorney can also file a federal lawsuit (mandamus action) to compel USCIS to adjudicate your application, though this is a last resort typically reserved for cases pending 18+ months beyond normal processing times.
