The Risks of Data Integration by DHS for US Citizens

With the increased merging of data across US agencies, it is not solely undocumented individuals who are being swept up by the intensified immigration directives; American citizens are also finding themselves ensnared.

In an incident in Alabama, Leonardo Garcia Venegas, an American citizen, found himself under forcible detention when immigration officials arrived at his work location in May. Despite his assertions of citizenship and presentation of Alabama issued identification, authorities allegedly disregarded his status, restraining him and placing him in handcuffs.

Venegas recounts another encounter, merely weeks later, where he was detained yet again. Although this time physical restraints were not used, officials reportedly ignored his claims of citizenship, dismissing his REAL ID as fraudulent.

Currently engaged in a legal battle with the government, Venegas formally accuses officials of deeming his identification documents fake, challenging their improper actions.

Jared McClain, from the Institute for Justice, voices concerns that authorities may treat extended detentions of citizens fitting specific profiles as an inconvenience justified by enforcement goals and associated rewards.

In contrast, DHS representative Tricia McLaughlin robustly defends the department’s actions, rejecting accusations of racial profiling. McLaughlin underscores that immigration enforcement targets those unlawfully residing in the US, not individuals based on racial or ethnic grounds, claiming that all arrest actions follow lawful suspicion protocols.

Unfortunately, episodes similar to these are occurring frequently. Reports indicate at least 170 American citizens were taken into custody by immigration authorities in just the initial three quarters of 2025.

The government's aggressive data pooling efforts have only expanded since the last administration, notably involving multiple federal records systems.

Recent federal notifications indicate substantial changes in data sharing strategies. A notable change involves DHS's SAVE database, now set to integrate voter data for immigration verification. Concurrently, the Social Security Administration (SSA) has formalized data sharing with DHS, further entrenching cross-agency data collaborations.

According to experts, these data policies set a concerning precedent, given that these systemic changes are often implemented swiftly without public scrutiny or prior notice.

Another regulatory update in late November saw the CMS agreeing to extend their data sharing arrangements to include citizen and immigration status data with DHS and ICE, raising further privacy alarms.

Government authorities defend such measures using legal frameworks that permit sharing of certain data with immigration officials, although advocates argue it bypasses protections for citizens and permanent residents.

Jennifer Ibañez Whitlock from the National Immigration Law Center remarks that the consolidation of government support data aimed at identifying immigrants amplifies surveillance risks.

Critics highlight potential risks in inaccurate or unupdated data, resulting in mistaken identity classifications, potentially stripping citizens of rightful government benefits or voter rights.

Technological concerns remain prevalent, with anecdotal evidence indicating processing errors even when documentation is provided. These errors erode trust and complicate guarantees of fair treatment.

Particularly vulnerable within this system are naturalized citizens, whose historical data mappings might yet inaccurately reflect earlier immigration statuses, compounding identity discrepancies.

Plaintiffs represented by CREW assert data system inaccuracies, illustrating ongoing systemic shortfalls that incorrectly label them based on outdated non-citizen status.

The alarming growth in data sharing necessitates greater safeguards and mechanisms for data rectification to prevent undue detentions, misclassification, and ensure true citizenship recognition.

The quick-paced enforcement policies raise potential human rights violations, cautioning that individuals may face expedited removal processes absent timely data reconciliations or legal defense.
