Filing Form N-400 in 2026: What Older Guides Get Wrong

Most of the N-400 advice circulating online was written before 2025, and several of its core facts are now wrong. The civics test changed. The form changed. The way you pay changed. A large fee increase has been proposed but has not taken effect, and that gap causes confusion of its own. This guide walks through the points where an older article will actively mislead you, and tells you what the official sources say today.

Everything below should be re-checked against the USCIS N-400 page before you file. That page carries the current form edition, the current fee, and the current filing addresses, and it is the only version of these facts that matters.

The civics test version is set by your filing date, not your interview date

This is the single most common mistake in older guides. USCIS announced the 2025 civics test in a Federal Register notice on September 18, 2025, and the rule is keyed to when your N-400 is received:

• Filed before October 20, 2025: you take the 2008 civics test.
• Filed on or after October 20, 2025: you take the 2025 civics test.

Your interview date is irrelevant to which test you get. Someone who filed in September 2025 and interviews in 2027 still takes the 2008 test. Someone who files today takes the 2025 test even if the interview happens quickly.

What the 2025 test actually looks like

The formats are not close to each other, and studying for the wrong one is a real risk:

• 2008 test: a 100-question study bank. The officer asks up to 10 questions and you need 6 correct.
• 2025 test: a 128-question study bank. The officer asks up to 20 questions and you need 12 correct. The officer stops as soon as you reach 12 correct answers (pass) or 9 incorrect ones (fail).

So the familiar shorthand of "100 questions, 10 asked, 6 to pass" describes a test that most new applicants will never sit. The 2025 bank and its official answers are published on the USCIS 2025 civics test page, and the filing-date rule is confirmed on the test updates page.

One thing that did not change: applicants who are 65 or older and have been permanent residents for at least 20 years still study a specially marked bank of 20 questions and are asked 10 of them, under both test versions.

The fee increase is a proposal, not the current price

DHS published a proposed rule on June 23, 2026 (RIN 1615-AD08) that would raise the N-400 fee to $1,330 on paper and $1,280 online, and would eliminate both the reduced fee and fee waivers for naturalization, keeping only the military exemption.

The comment period closed on August 24, 2026. As of today there is no final rule and no effective date. That means:

• The current fees are still $760 on paper and $710 online.
• The $380 reduced fee is still available to households with income above 150% and at or below 400% of the Federal Poverty Guidelines.
• Fee waivers on Form I-912 are still available at the lower income levels and for certain means-tested benefits and hardship situations.

Guides that quote the proposed numbers as if they were in force are wrong today, and guides that promise the increase "will not happen" are guessing. Check the fee on the N-400 page on the day you mail.

The $50 online discount can quietly cost you hundreds

Filing online saves $50 over paper, so almost every guide tells you to file online. That advice is right only if you are paying the full fee.

Applicants requesting the reduced fee or a fee waiver cannot file the N-400 online. Those requests are paper-only. If you qualify for the $380 reduced fee and file online anyway to save $50, you have just paid $710 instead of $380. The reduced fee is now requested directly in the N-400 itself rather than on a separate Form I-942, so it costs you nothing but a few extra questions to claim it; the eligibility rules are on the reduced fee page.

Work out your fee category first, and let that decide whether you file on paper or online.

Check the form edition, and stop trusting old Part and Item numbers

The current N-400 edition is 01/20/25. USCIS reorganized the form when it added the fee-reduction questions, so the Part and Item numbers cited in articles written even two years ago no longer point at the same questions. Download a fresh copy right before you fill it in, and never mix pages from two editions in one package, which is a rejection on its own.

Payment for paper filings also moved to electronic methods: USCIS now expects a credit or debit card authorization on Form G-1450 or an ACH debit on Form G-1650, rather than a check or money order. Confirm the accepted payment methods on the N-400 page before you mail, because this is exactly the sort of detail that gets a package returned unopened.

A missing document can now mean a denial, not a Request for Evidence

Older guides reassure readers that USCIS will send a Request for Evidence if something is missing. That is no longer a safe assumption. Under USCIS policy updated on August 4, 2026 (Policy Alert PA-2026-05), officers have full discretion to deny a request outright, without first issuing an RFE or a Notice of Intent to Deny, when the applicant fails to submit required initial evidence.

Practically, this raises the cost of a sloppy package from "a few months of delay" to "a lost filing fee and a fresh start." Assemble the case as though there will be no second chance to add anything, because there may not be. The current policy is published in the USCIS Policy Manual, whose update log is the fastest way to see what has changed recently.

What to do with this

Before you file, verify four things on official pages rather than in any article, including this one: the current form edition, the current fee and which fee category you fall into, which civics test your filing date puts you in, and the accepted payment method. Then build a package that is complete on the first submission.

ezgreen keeps its questions and forms aligned with the current editions and walks you through the evidence one plain-language step at a time, so what you mail matches what USCIS is actually asking for this year.
