On August 25, 2026, U.S. Citizenship and Immigration Services issued Policy Alert PA-2026-10, updating Volume 12 of the USCIS Policy Manual. The guidance formally reintroduces USCIS neighborhood investigations, also called personal investigations, for permanent residents applying for citizenship.
What Are Neighborhood Investigations?
Section 335(a) of the Immigration and Nationality Act has authorized investigations of naturalization applicants since 1952. By 1991, the former Immigration and Naturalization Service had abandoned the practice and relied mainly on FBI criminal history and security checks. USCIS has now ended the general waiver of these investigations, building on a Policy Memorandum Director Edlow issued on August 22, 2025, which USCIS says has already led to a number of investigations.
According to USCIS, information from members of the community can reveal details that interviews and documents may not, helping officers assess good moral character, attachment to the principles of the U.S. Constitution, and other statutory requirements.
Who Decides Whether an Investigation Occurs?
The USCIS Fraud Detection and National Security Directorate, in coordination with the Field Operations Directorate, decides whether to conduct or waive an investigation. That decision rests on an individualized, discretionary review of the applicant’s record or of classes of cases.
The Role of Character Reference Letters
Applicants may voluntarily submit testimonial or character reference letters. USCIS prefers letters from U.S. citizens who are not family members, attesting to the applicant’s character, loyalty to the United States, and attachment to the Constitution. USCIS will consider these letters when deciding whether to waive an investigation.
Documents and Testimony Will Be Verified
The guidance reaffirms that USCIS examines every factor relating to eligibility and confirms the information you provide through documents, investigation findings, and interview testimony. Consistency across your Form N-400, supporting records, and interview answers is essential. Addresses, employment history, travel dates, and tax filings should match what appears in your prior immigration filings. Any discrepancy, even an innocent one, may prompt further questions and could delay a decision on your application.
Our Perspective
This guidance is effective immediately and applies to applications pending or filed on or after August 25, 2026. Ahluwalia Law Offices recommends that applicants review their full immigration history before filing and consider thoughtful, accurate reference letters.
