On August 22, 2025, USCIS announced it will once again consider conducting “neighborhood investigations” under INA §335(a) for people applying for U.S. citizenship. These personal investigations may involve checks in the vicinity of an applicant’s residence and workplace, usually covering at least the five years prior to filing Form N-400. The goal is to corroborate eligibility factors such as continuous residence, good moral character, attachment to the Constitution, and overall community standing.

What’s important right now:

• New and uncertain: This change is very recent, and USCIS has not provided clear guidance on how frequently these investigations will be used in practice.
• Possible role of testimonial letters: USCIS notes that testimonial letters from neighbors, employers, or colleagues may help support an applicant’s case and, in some situations, could lead to a waiver of the investigation. However, it is not yet clear to what extent such letters will actually be requested or expected.
• No change in filing process (for now): Until we see how this policy is applied, the best course is to continue preparing and submitting naturalization applications as before, focusing on accurate addresses, employment history, and supporting documentation.
• We will monitor closely: As USCIS begins implementing this policy, we will track whether community references become a standard expectation or remain a discretionary factor.

Bottom line: This policy is new and evolving. Applicants should not delay filing based on uncertainty. For now, prepare applications carefully and expect additional guidance as USCIS practice becomes clearer.
