A Peruvian citizen living legally in Kansas was arrested by ICE after she admitted to falsely claiming U.S. citizenship on a voter registration form and casting a ballot in the 2024 general election, part of a broader federal crackdown on noncitizen voting.

Homeland Security Investigations agents took Mariana Alexandra Dewey into custody at her Wichita residence on September 1 after election records tied her to a provisional ballot cast in Sedgwick County during the November 5, 2024, general election. Dewey, a lawful permanent resident from Peru, had already pleaded guilty to disorderly election conduct under Kansas law before federal agents showed up at her door.

The Department of Homeland Security announced the arrest Thursday, framing it as one piece of the Trump administration's expanding enforcement campaign against noncitizens accused of voting in American elections. DHS Secretary Markwayne Mullin did not hold back in the agency's news release.

Mullin: 'If even one noncitizen votes, that steals the voice of a U.S. citizen'

The DHS release laid out the government's account in plain terms. Dewey submitted a Kansas voter registration application and certified under penalty of perjury that she was a U.S. citizen. She then cast a provisional ballot on Election Day 2024. When HSI agents later interviewed her, Dewey acknowledged she was a lawful permanent resident, not a citizen, and admitted she had voted, Fox News reported.

She pleaded guilty to the Kansas charge before her arrest. The specific date of that plea and any sentence she received have not been disclosed.

Mullin issued a statement that went beyond the single case:

"This alien violated the sacred right of every American citizen. If even one noncitizen votes, that steals the voice of a U.S. citizen."

He added that DHS would "continue to investigate, seek criminal prosecution and ultimately remove aliens who vote to ensure free, fair and honest elections." The language signals that Dewey's case is not an endpoint but a template, arrest, prosecute, deport.

Whether Dewey faces additional federal charges beyond the Kansas guilty plea remains unclear. The DHS release referenced criminal prosecution and removal as the department's stated goals, but no federal indictment was mentioned in the announcement. Her current custody status beyond being held by ICE has not been detailed.

Kansas case fits a pattern DHS is building nationwide

Dewey's arrest did not land in isolation. DHS pointed to charges against four noncitizens in New Jersey accused of illegally voting in federal elections or falsely claiming U.S. citizenship. The department also cited enforcement actions involving nationals from Colombia, Slovakia, Australia, Mexico, and Mauritania, a list that spans multiple continents and immigration statuses.

The breadth of those cases matters. Critics of noncitizen voting enforcement have long argued that such incidents are vanishingly rare and that existing safeguards catch them. DHS is building a counter-narrative through accumulation: case after case, state after state, each one announced publicly with the secretary's name attached.

An Australian lawful permanent resident was recently charged with illegally voting in two separate federal elections, another case in which legal residency did not confer the right to vote but someone cast a ballot anyway.

Provisional ballots and a system built on self-certification

One detail in the Dewey case deserves closer scrutiny. She cast a provisional ballot, the type of ballot issued when a voter's eligibility cannot be immediately confirmed at the polling place. Provisional ballots exist as a safeguard, a way to let someone vote while election officials verify their registration. Whether Dewey's provisional ballot was ultimately counted has not been disclosed.

But the larger vulnerability is upstream. Kansas, like most states, relies on applicants to self-certify their citizenship on voter registration forms. Dewey signed that certification under penalty of perjury. The system caught her, eventually. HSI agents conducted an interview, she admitted the truth, and a guilty plea followed. The question is how many similar certifications go unchecked.

The Justice Department has warned election officials in all 50 states that they face prosecution over failures to address noncitizen voting, a signal that the federal government views the problem as systemic, not isolated.

DHS has also directed ICE to deport illegal immigrants who vote in American elections, a policy that extends the consequences beyond criminal penalties to permanent removal from the country. For lawful permanent residents like Dewey, a conviction tied to false citizenship claims can trigger deportation proceedings that strip away years of legal residency.

No motive, no defense statement, and open questions remain

The DHS announcement did not address why Dewey registered and voted. No motive was offered. No statement from a defense attorney appeared in the release. Whether she had legal representation at the time of her guilty plea or her ICE arrest is unknown.

How election officials first flagged Dewey's registration as potentially fraudulent also remains unexplained. The DHS release said election records showed she submitted the registration application, but it did not describe the mechanism that triggered the investigation, whether it was a routine audit, a tip, or a cross-reference with immigration databases.

Voter fraud investigations elsewhere have drawn federal resources in recent months. The FBI deployed agents to Los Angeles's Skid Row as part of a voter fraud probe tied to a mayoral primary, a sign that enforcement agencies are treating election integrity cases with increasing seriousness across jurisdictions.

Dewey's case also raises a practical question about accountability at the local level. Sedgwick County processed her registration and issued a provisional ballot. The state charge she pleaded guilty to, disorderly election conduct, is a Kansas offense, but the federal government is now layering its own enforcement on top. Whether county or state officials face any scrutiny for accepting the registration in the first place is not addressed in the DHS release.

Across the country, local prosecutors and officials face growing pressure over accountability failures in the justice system, a dynamic that extends well beyond election cases but shares the same underlying tension between enforcement and permissiveness.

DHS is sending a message one arrest at a time

Secretary Mullin's statement framed noncitizen voting as theft, one illegal ballot canceling out one citizen's voice. That framing carries political weight in an environment where election integrity remains a flashpoint. But DHS is backing the rhetoric with specific arrests, specific guilty pleas, and specific names.

Dewey is a lawful permanent resident, not someone who crossed the border illegally. She lived in Wichita. She had legal status. And she signed a form swearing she was a citizen when she was not, then voted. The system eventually caught her, but only after the ballot was cast.

The question voters should be asking is not whether this case is rare. It is whether a system that relies on the honor code to protect the ballot box is a system worth trusting.
