Form N-400, the Application for Naturalization, can be filed online through USCIS's online filing portal, and you'll receive a $50 filing fee discount by doing so. The form adapts based on your answers and alerts you to missing information before submission, so you won't discover problems after you've finished.
You can begin filing up to 90 calendar days before completing your continuous residence requirement, depending on your eligibility category (such as 3+ years as a permanent resident married to a U.S. citizen). Once submitted online, USCIS issues you a receipt number to track your case immediately.

Creating Your Account and Starting Your Application
To file online, create an account at myaccount.uscis.gov. Once logged in, the N-400 form (dated January 20, 2025) guides you through the process. The form is interactive—it only shows questions relevant to your situation based on how you answer earlier questions, and provides real-time alerts about missing information or required evidence. You can save your progress at any time and return to finish later, though you must complete and submit the full application before your naturalization interview.
Who Can File Online and What It Costs
You can file N-400 online unless you're requesting a fee waiver (Form I-912) or a reduced fee (Form I-942). If you need either of these, you must submit a paper application instead. The $50 filing fee discount is a real advantage: online filing costs significantly less than submitting by mail. Payment is processed immediately using a valid credit or debit card or through direct bank account debit, and your application submits only after payment succeeds.
Uploading Documents in the Right Format
Your supporting documents must be in PDF, JPG, or JPEG format and cannot exceed 12 megabytes each. If any original documents are in a foreign language, you must also submit a certified English translation alongside the original. Common documents include your green card, birth certificate, state ID, passport, tax returns, and employment verification. Scan these clearly at standard resolution to keep file sizes under 12 MB, and upload them in the order the form requests.
Filing Before You're Technically Eligible
One significant advantage of online filing is that you can start the process up to 90 days before completing your continuous residence requirement. This lets you move ahead without waiting until the final day. For example, if you'll complete 5 years as a permanent resident on December 1st, you can begin your N-400 on September 2nd. USCIS will schedule your interview after your eligibility date arrives, ensuring you meet all timing requirements before any oath ceremony.
Checking Your Status and Next Steps
Upon online submission, you'll receive a receipt notice with a case number to check your application status online. USCIS processes all naturalization applications—whether filed online or by mail—through the National Benefits Center or your local field office, with processing times posted on their case status website. You won't need to mail anything or follow up in person until USCIS schedules your naturalization interview.
