N-400

N-400 Naturalization

Application for U.S. citizenship by a lawful permanent resident meeting residence, physical presence, and good moral character requirements.

N-400N-648 (disability exception)N-426 (military service)

Naturalization is arithmetic and disclosure: days outside the country counted exactly, and every arrest disclosed with its certified disposition — including the ones the client believes were expunged. Attest builds the travel table from the passport stamps and shows the count.

The document checklist

What the client is asked for — before you have to ask twice.

A new N-400 starts with this checklist already on the case. Your client sees it in the portal in their own language, uploads from their phone, and each item flips to received as it arrives.

Required

5 items
  • Green card (front and back)
  • Tax returns or IRS transcripts — 5 years (3 if married to a U.S. citizen)
  • Complete travel history with exact dates
  • Address and employment history
  • All passports held during the statutory period

If it applies

7 items
  • Marriage evidence (3-year rule applicants)
  • Certified dispositions for ALL arrests and citations — ever
  • Selective service registration proof
  • Child support compliance evidence
  • Legal name change documents
  • Form N-648 medical certification (disability exception)
  • Military service records (N-426, military-based filings)

What the evidence is measured against

An evidence map, criterion by criterion.

Attest reads every document on the case and maps it to the elements below — marking each one supported or a gap, and citing the page it relied on. A gap is stated plainly rather than papered over.

01Continuous residence
02Physical presence
03Good moral character
04Attachment to constitutional principles
05English and civics requirements
06Marital union (3-year rule)

Where these cases get RFE’d

The grounds USCIS comes back on.

When a notice does arrive, upload it — Attest extracts each request, maps it against what you already have on file, and drafts a cited response plan. The response deadline it finds is docketed only after you confirm it against the notice page itself.

Continuous residence / physical presence math

A trip over six months, or a day count that doesn't reconcile with the stamps.

Good moral character — undisclosed or undocumented arrests

An incident omitted, or disclosed without the certified disposition.

Tax compliance

A missing return, or a filing status inconsistent with the marital claim.

Selective service failure to register

A male applicant in the covered cohort with no registration and no explanation.

3-year-rule marital union evidence

Living in marital union for the full three years isn't documented.
