Find illegals with Databases

Passport cross-check: Match rolls against State Department passport records — SAVE already pulls this. Anyone registered without a passport or naturalization record gets flagged. DMV citizenship flags: Florida already does this weekly. DMVs collect non-citizen status at license issuance; pipe that straight into the voter file. Jury disqualification data: Courts flag jurors as non-citizens or felons. Feed those lists to election offices — Florida uses this. Felony conviction databases: Cross-check state and federal criminal records for disqualifying convictions still on the rolls. IRS address matching: Compare registration addresses against IRS filings to catch people registered at addresses they don't actually live at. USPS change-of-address: Run rolls through NCOA data to find movers who never updated their registration. Commercial data brokers: DHS agents already use Accurint and Clear. Layer those on top of federal records for deeper identity resolution. Athena Toolbox: HSI's Sandia-built platform already ran New Jersey and Pennsylvania rolls against all HSI databases — scale that nationally. Probabilistic record linkage: Use Fellegi-Sunter or GPU-accelerated FAST-ER algorithms on public rolls to catch duplicates that simple name matching misses. Anomaly detection ML: Train models on registration snapshots to flag sudden spikes, unnatural age clusters, or precinct-level turnout outliers. Graph neural networks: Build similarity graphs across name, DOB, address, and license number — catches coordinated registration rings. Naturalization timing check: Flag anyone who registered before their naturalization date using USCIS records. Post-election ballot scrub: After voting, re-run every cast ballot through SAVE and death indexes to catch ineligible votes after the fact. Commercial voter-history files: ICE is already contracting for all-50-state voter history files — cross those against federal databases for patterns. Strongest hooks for pitches: the 250,000 non-citizens DHS claimed in four states, or the 400,000 dead people found across 25 states
