About this calculator
The N-400 application for naturalization currently costs $760 filed on paper or $710 online (biometrics is included in that fee as of the 2024 fee rule, no longer billed separately for most applicants). On top of the government fee, budget for a certified copy of your green card if it's lost, a passport-style photo if applying by paper, travel to the biometrics appointment and interview, and time off work for both. Many applicants also pay for a citizenship test prep class or study materials, typically $50-$200, and some low-income filers qualify for a full or partial fee waiver via Form I-912. This calculator adds the required government fee to the optional prep and logistics costs so you can see the realistic total instead of just the headline number.

FAQ
Is there still a separate biometrics fee?
No. Since the April 2024 fee rule, biometrics services are included in the N-400 fee for most applicants, so you no longer pay $85 separately. Some categories, like applicants over 75, are exempt from biometrics entirely.
Who qualifies for a fee waiver?
Applicants with household income at or below 150% of the federal poverty guideline, or receiving a means-tested public benefit, or facing financial hardship can file Form I-912. Approval isn't automatic, so file it with clear documentation of income and benefits.
Do I need a lawyer to naturalize?
Most straightforward cases don't need one. Get legal help if you have any arrests, extended time abroad that could break continuous residence, unpaid taxes, or a prior immigration violation, since those issues can turn a routine application into a denial or removal referral.
How long does N-400 processing take?
Current average processing time is roughly 5-10 months depending on field office, though it varies widely by location. Check your specific field office's processing time on the USCIS case processing times page rather than relying on a national average.
Accuracy and limitations
- Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
- Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
- This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
