California aerospace worker is charged with falsely claiming U.S. citizenship and using another person's naturalization number

Federal authorities in Southern California arrested Mexican national Alma Patricia Contreras Villafana after prosecutors said she falsely claimed U.S. citizenship to work for decades at Howmet Aerospace, a military contractor in Torrance. Court papers say she first used a false Form I-9 attestation in 1996, was ordered removed in 2003, and submitted another allegedly false citizenship claim in 2026 using someone else's naturalization certificate number; she faces wire fraud, identity theft, document fraud, and false-claim charges.
Why it matters: The case combines interior immigration enforcement, unauthorized employment, and false-claim-to-citizenship allegations at a defense contractor, raising questions about workplace verification and access to sensitive jobs. Supporters of tougher enforcement will point to national-security and document-fraud concerns, while others may focus on how employment screening and long-term unauthorized presence went undetected for years.
