Second Circuit Hands Border Agents Blanket Power to Search Phones Without Suspicion

A federal appeals court just made it official. Border agents can pick up any traveler’s cellphone at an airport or land crossing, scroll through messages, photos and browsing history, and do so for no reason at all. The U.S. Court of Appeals for the Second Circuit delivered that holding on September 17, 2026, in a ruling that aligns the circuit with others but widens the gap between digital reality and constitutional tradition.

The case, United States v. Alisigwe, began when Chinwendu Alisigwe, a green card holder, had his phone searched twice upon entering the country. Agents found evidence that later supported convictions for conspiracy to commit money laundering and related charges. Alisigwe moved to suppress the material. He argued the searches violated the Fourth Amendment because they lacked even reasonable suspicion. He also contended that the First Amendment demanded a warrant to protect private thoughts, associations and newsgathering material that phones routinely contain.

The district court denied the motion but required reasonable suspicion. The Second Circuit went further. It held that manual searches of cellphones qualify as routine border inspections. No suspicion needed. No warrant required. The decision, written by Judge Steven J. Menashi and joined by Judges Hector Gonzalez and Eunice C. Lee, treated the phone like any other piece of luggage.

“Under our precedents, no suspicion is required before the government searches a traveler’s property at the border,” Menashi wrote. “Because a cellphone is property, our precedents establish that the government does not need to have reasonable suspicion before searching a traveler’s cellphone at the border.” The panel rejected the idea that the Supreme Court’s 2014 decision in Riley v. California, which requires warrants for phone searches incident to arrest, applies at the border. It also dismissed First Amendment arguments for heightened protection.

But phones are not luggage. A single device holds intimate correspondence, location data tracking nearly every movement, photographs of family and friends, medical records, financial details and logs of associations that reveal political, religious and journalistic ties. The Knight First Amendment Institute drove that point home in an amicus brief and subsequent statement. (Knight First Amendment Institute)

“Today’s decision leaves Americans’ most sensitive information open to search at the border without any suspicion at all,” said Scott Wilkens, senior counsel at the institute. “Our phones hold our private thoughts and associations, photographs of our family and friends, and a log of our nearly every movement. The First Amendment should require the government to get a warrant before searching them. We’re disappointed the court declined to recognize that.”

The ruling arrives at a moment when Customs and Border Protection data show the practice remains rare yet expanding. In fiscal year 2025 the agency searched electronic devices of roughly 55,000 travelers out of more than 420 million encounters, or less than 0.01 percent, according to CBP’s own figures. (U.S. Customs and Border Protection) Still, those numbers have risen in recent years. And the power now carries explicit judicial blessing across more circuits.

Other appeals courts reached similar conclusions on manual searches before this week. The Fourth Circuit did so in July 2026. Yet the Second Circuit’s decision carries extra weight. It covers New York, Connecticut and Vermont, major international gateways. It also resolves conflicting signals from district courts within its territory. Some judges there had begun requiring warrants or at least reasonable suspicion. Those experiments now end.

Critics see a constitutional mismatch. The border-search exception dates to an era when luggage contained clothing and papers, not the equivalent of a complete digital life. Supreme Court precedent from 1977 in United States v. Ramsey allowed suspicionless mail searches at the border. Lower courts extended that logic to electronics. But technology moved faster than doctrine.

And the ruling stops short of addressing forensic searches that copy entire device contents. CBP policy still requires reasonable suspicion for those deeper inspections and senior approval. The Second Circuit panel left that question for another day. That leaves room for further litigation and possible Supreme Court review.

Journalists, lawyers and activists have particular reason for concern. Phones often store confidential source information, draft articles, client communications and details of sensitive associations. The Knight Institute and the Reporters Committee for Freedom of the Press highlighted those burdens in their brief. They argued that the mere prospect of such searches can chill speech and newsgathering at the border. The court was unmoved.

Defenders of the decision point to national security and law enforcement needs. Agents have used device searches to uncover child exploitation material, terrorism links, intellectual property theft and smuggling operations. The government maintains that requiring suspicion or warrants would hamper its ability to act quickly at ports of entry where volume is high and time is short.

Yet the opinion’s breadth invites questions. If no suspicion is required, what limits exist on scope or duration? The panel suggested routine searches remain bounded by reasonableness. Exactly what that means for a device containing years of data remains unclear. Travelers can refuse to provide passcodes in some circumstances, but doing so may lead to device seizure or entry denial.

Corporate counsel already advise executives and employees to minimize sensitive data before international travel. Some companies issue clean devices for border crossings. Others explore technical solutions such as remote wipe capabilities or encrypted partitions. The Second Circuit’s decision will likely accelerate those practices.

Legal observers expect petitions for rehearing or Supreme Court review. The circuit split on forensic searches persists. And the broader question of whether Riley’s logic should influence border doctrine has not received definitive high-court attention. Until then, the default rule stands: agents need nothing more than the fact that you are crossing the border.

Scott Wilkens captured the stakes plainly. The phones contain “our private thoughts and associations.” The court decided that at the border those thoughts travel with diminished protection. How that balance holds as technology evolves will shape privacy expectations for millions of international travelers in the years ahead.

Bloomberg Law reported the decision hours after its release, noting the panel’s rejection of both Fourth and First Amendment limits.

The Second Circuit has spoken. Border agents now operate with clearer authority. Whether that authority eventually collides with a more skeptical Supreme Court remains the next chapter.
