Understanding USCIS Naturalization Fees in 2026
USCIS periodically revises its filing fees to reflect operational costs, inflation adjustments, and statutory requirements. In 2026, USCIS continues implementing fee updates designed to ensure the agency remains largely fee-funded while maintaining processing capacity.
For most applicants, the fee to file Form N-400, Application for Naturalization, remains the primary government cost.
As of 2026:
- The standard filing fee for Form N-400 is $710 if filed online.
- The standard filing fee is $760 if filed by mail (paper filing).
- The reduced filing fee for those who can demonstrate with proper documentation that their household income is not more than 400% of the Federal Poverty Guidelines is $380 for paper filings.
- The filing fee is $0 for those who served in the military and meet the requirements of INA section 328 or 329.
- The fee is $0 for those who qualify for a fee waiver using form I-912, Application for Fee Waiver.
These amounts include the cost of biometric services, which is no longer charged as a separate fee.
Because USCIS may adjust fees periodically, including annual inflation-based updates, applicants should always confirm the correct amount at the time of filing. Submitting the incorrect fee can result in rejection and delay.
Eligibility and Requirements for Naturalization in 2026
Navigating the path to U.S. citizenship in 2026 requires a clear understanding of the eligibility criteria set forth by immigration law. Applicants must be at least 18 years old and hold lawful permanent resident status for the required period, typically five years, or three years if married to a U.S. citizen. Demonstrating good moral character is essential, as is showing a basic command of the English language and a foundational knowledge of U.S. history and government.
In addition to these core requirements, immigration law mandates that applicants maintain continuous residence and physical presence in the United States. Specifically, you must not have been absent from the country for more than 30 months during the qualifying period. These rules can be complex, and even minor errors or misunderstandings may impact your eligibility.
An experienced Colorado immigration law firm can provide strategic guidance to help you assess your qualifications and gather the necessary documentation. The experienced naturalization lawyers at Anzen Legal Group are dedicated to guiding clients through every step, ensuring they meet all requirements under current immigration regulations. By working with a trusted law firm, you can approach the naturalization process with confidence, knowing your case is in the capable hands of your immigration attorney.
2026 Fee Structure Changes and Policy Updates
Annual Inflation Adjustments
Recent rulemaking allows USCIS to implement annual adjustments tied to inflation metrics. This means certain application fees, including naturalization, may increase over time based on economic indicators.
While the 2026 naturalization filing fee has not dramatically increased compared to prior years, the structure now permits more regular adjustments. Applicants should plan accordingly and monitor fee updates before submitting their applications.
Online vs. Paper Filing Differences
One of the most noticeable changes in recent years is the difference in cost between online and paper filing.
- Online filing is typically less expensive.
- Paper filing carries a slightly higher fee due to administrative handling.
Online filing may also provide faster receipt notices and electronic case tracking, which applicants often find helpful.
Electronic Payment Requirements
USCIS continues shifting toward electronic payment systems. Applicants should be prepared to submit payment through accepted electronic methods when filing online. For paper applications, as of October 2025 cashier’s checks and money orders are no longer accepted for most filings. Failure to use acceptable payment methods may result in application rejection.
Application Process for Naturalization in 2026
The journey to citizenship in 2026 involves several important steps, each requiring careful attention to detail. The process begins with submitting Form N-400, Application for Naturalization, to U.S. Citizenship and Immigration Services (USCIS). As naturalization attorneys with decades of experience, we can assist you in preparing and filing your application, ensuring all required documents (such as your green card, passport, and birth certificate) are included and properly organized.
Once your application is submitted, you will be scheduled for a biometrics appointment, where your fingerprints and photographs will be collected. Following this, USCIS will invite you to an interview with an immigration officer. During the interview, you will be tested on your knowledge of U.S. history, government, and civics, as well as your ability to read, write, and speak English.
Throughout this process, having an immigration lawyer by your side can make a significant difference. Legal representation ensures that your application is complete, your rights are protected, and you are fully prepared for each stage. If your application is approved, you will be invited to a naturalization ceremony, where you will take the Oath of Allegiance and officially become a U.S. citizen. Our immigration services are designed to support you from start to finish, helping you achieve your goal of citizenship with confidence.
What the Naturalization Fee Covers
USCIS is primarily funded by filing fees rather than general tax revenue. As a result, application fees directly support case adjudication operations. The Form N-400 filing fee covers services provided by USCIS throughout the naturalization process, including:
- Intake and processing of the application
- Background checks and security screenings
- Biometrics processing
- Scheduling and conducting the naturalization interview
- Administration of the English and civics examinations
- Review of eligibility under federal immigration law
- Issuance of approval and oath ceremony scheduling
At Anzen Legal Group, the immigration department is staffed by experienced lawyers who guide clients through all of these steps of the naturalization process, ensuring that you meet all statutory and USCIS administrative requirements and have the best chance of approval.
Immigration Law and Legal Framework Governing Naturalization
Naturalization eligibility is governed by the Immigration and Nationality Act (INA), primarily under INA §§ 316 and 319. Naturalization is also governed by U.S. nationality law, which sets the requirements for citizenship, legal status, and related immigration procedures. Key statutory requirements include:
- Lawful permanent resident status for at least five years (or three years if married to a U.S. citizen, subject to additional conditions)
- Continuous residence and physical presence in the United States
- Good moral character during the statutory period
- English language proficiency
- Knowledge of U.S. history and government
- Attachment to the principles of the U.S. Constitution
Applicants must demonstrate eligibility through documentation and testimony at the USCIS interview. Because the filing fee is nonrefundable, even if the application is denied, it is critical to ensure eligibility before filing. Working with a Colorado naturalization lawyer can help confirm that all statutory requirements are satisfied prior to submission.
Fee Waivers and Reduced Fees in 2026
USCIS recognizes that the naturalization filing fee may present a financial burden for some applicants. Accordingly, the agency provides limited options for fee waivers and reduced fees.
Full Fee Waiver
Applicants may request a full fee waiver if they:
- Receive means-tested public benefits,
- Have household income at or below 150% of the Federal Poverty Guidelines, or
- Can demonstrate financial hardship
To request a fee waiver, applicants must submit Form I-912 with supporting documentation. If approved, USCIS will process the naturalization application without requiring the standard filing fee.
Reduced Fee
Certain applicants whose household income exceeds the fee waiver threshold but remains below 400% of the Federal Poverty Guidelines may qualify for a reduced filing fee. Eligibility requirements are specific and must be documented properly.
Improperly prepared fee waiver or reduced fee requests can result in rejection. A Colorado immigration lawyer can assist with preparing and organizing the necessary financial documentation.
Additional Legal Services Costs Beyond the Filing Fee
Although the government filing fee is the primary expense, applicants should also anticipate other potential costs:
- Certified copies of civil documents
- Translation services for foreign-language documents
- Passport photos (if required)
- Travel expenses to biometrics or interview appointments
- Study materials or English language instruction
- Naturalization attorney representation fees
While legal representation is not required, many applicants choose to work with a Colorado immigration law firm to ensure their case is properly prepared. This is particularly crucial for applicants who have potential challenges, including:
- Extended travel outside the United States
- Prior immigration violations
- Criminal history
- Tax filing concerns
- Selective Service issues
Errors or omissions may result in delays, requests for evidence, or denial. Having an experienced Fort Collins naturalization attorney gives you the best chance of anticipating potential hurdles and immigration consequences of your past actions and strategizing accordingly.
Why Accurate Preparation Matters When Applying For Naturalization
The naturalization filing fee is nonrefundable once USCIS begins processing the application. If an application is denied due to ineligibility or incomplete documentation, the applicant must typically repay the full filing fee to reapply.
Proper preparation helps reduce the risk of unnecessary expense and delay.
A Colorado naturalization lawyer can assist with:
- Evaluating eligibility under current immigration laws
- Reviewing travel history and continuous residence requirements
- Assessing good moral character concerns, such as criminal convictions
- Preparing responses to complex questions
- Attending the naturalization interview
As naturalization lawyers with decades of experience, we provide clients with a realistic assessment of the case, including potential challenges. Clients have reported positive experiences with our Colorado immigration lawyers who approach each case with compassionate, experienced, and responsive care, which contributes to a positive overall experience.
