USCIS Policy Alert — Investigations and Examinations for Naturalization Eligibility details to check
The official update is dated August 25, 2026.
The policy concerns Form N-400, Application for Naturalization.

The stated lookback period is at least five years immediately before filing.
The authority cited is section 335(a) of the Immigration and Nationality Act.
USCIS N-400 questions, answered
Will USCIS visit every naturalization applicant's neighborhood?
No. The guidance allows personal investigations and provides for case-by-case decisions on whether an investigation is conducted or waived.
How far back can a neighborhood investigation look?
USCIS says the investigation covers at least the five years immediately before the naturalization application was filed.
Does this create a new eligibility requirement for citizenship?
No. It changes and formalizes USCIS investigation procedures used to verify the existing naturalization requirements.
How this changes the next step
Some naturalization applicants may face checks involving their residence, employment, or community contacts.
USCIS may use information from an investigation together with the application record and naturalization examination when deciding eligibility.
The update does not mean every Form N-400 applicant will receive a neighborhood investigation.
Checks to make before you act
- Make sure the residence and employment history on Form N-400 is complete and accurate.
- Keep records that support continuous residence, employment history, and other naturalization requirements.
- Respond by the stated deadline if USCIS requests additional evidence.
- Do not assume a neighborhood investigation will occur in every case.
Read the update beside your own stage
USCIS had already resumed case-by-case personal investigations through an August 2025 policy memorandum.
The August 25, 2026 action incorporates the policy into the centralized USCIS Policy Manual.
The update addresses investigation and examination procedures; it does not change the statutory eligibility requirements for naturalization.
What this cannot decide for you
- USCIS does not state how many applicants will receive a neighborhood investigation.
- USCIS does not publish an estimated processing-time effect for this update.
- Whether an investigation is conducted or waived is case-specific.
- The official update provides no publication time, only the date.
