USCIS Resumes Personal Investigations for Naturalization Applicants: What You Should Know

On August 22, 2025, U.S. Citizenship and Immigration Services (USCIS) announced that it is resuming personal investigations—sometimes called “neighborhood investigations”—for certain naturalization applicants, as authorized under Section 335(a) of the Immigration and Nationality Act (INA)

This change signals a return to more traditional vetting methods that had largely been waived in recent decades. While background checks through the FBI will continue, USCIS may now also investigate an applicant’s residence, workplace, and community reputation to confirm eligibility for U.S. citizenship.

What Does This Mean for Naturalization Applicants?

Naturalization has always required proof of good moral character, attachment to the U.S. Constitution, and compliance with immigration laws. Under the updated policy:

  • Community and workplace checks: Officers may contact neighbors, employers, co-workers, or associates to verify information about an applicant.
  • Additional evidence requests: Applicants may be asked to provide letters or statements from people who know them and can attest to their character.
  • Individualized discretion: Not every applicant will face an investigation, but USCIS will decide on a case-by-case basis whether one is necessary.

Submitting supporting evidence proactively with your Form N-400, Application for Naturalization—such as proof of long-term community involvement, employment records, or letters of reference—may help avoid delays.

Why Is USCIS Doing This?

According to USCIS, the goal is to ensure applicants truly meet the requirements of INA 316 and INA 335. U.S. citizenship is more than a benefit—it carries rights and responsibilities, and USCIS wants to ensure applicants are fully qualified
