At the U.S. Border, Your Phone Can Become Part of Your Visa Interview

Richard T. Herman

A Ghanaian traveller who secures a U.S. visitor visa has already cleared a formidable hurdle. According to the State Department’s fiscal year 2025 B-visa statistics, the adjusted refusal rate for Ghanaian nationals was 64.34 percent. Those who succeed may understandably assume that the most difficult scrutiny is behind them.

At the American airport, however, a Customs and Border Protection officer may ask to inspect something far more revealing than a passport: the traveller’s phone.

Under CBP’s updated directive governing border searches of electronic devices, officers may examine phones, laptops, tablets, cameras, storage drives, smartwatches and other electronic devices carried across the border. CBP reported 55,318 electronic-device searches in fiscal year 2025, including 50,922 basic searches.

The searches remain uncommon compared with the enormous volume of international travel. But rarity offers little comfort to the person selected. A phone can expose years of messages, photographs, emails, contacts, financial information and travel plans. It can also reveal whether the journey described at the airport matches the journey the traveller appears to be planning.

The visa decision is not the final decision

A U.S. visa does not guarantee entry. As the State Department explains in its official visitor-visa guidance, the visa permits a foreign national to travel to a U.S. port of entry and request admission. CBP then decides whether the traveller may enter and how long the stay will be authorised.

The consular officer who issued the visa evaluated the applicant’s DS-160 form, interview and available government records. The CBP officer evaluates the actual journey being presented on the day of arrival. The questions may therefore begin again: Why are you visiting? How long will you stay? Where will you live? Who is paying for the trip? What do you do in Ghana? When will you return?

A traveller’s answers should be truthful, concise and consistent with the visa application, itinerary, luggage and other available information. A tourist should be able to explain where the holiday will take place and how it will be financed. A business visitor should know the company, conference or transaction involved. Someone visiting relatives should be prepared to identify those relatives, where they live and the anticipated length of the visit.

Supporting documents can help. A return itinerary, hotel reservation, conference registration or business correspondence may reinforce a credible explanation. But paperwork cannot substitute for a truthful and coherent account. A thick folder will not cure an inconsistent story.

A phone may become part of that assessment. Messages about beginning employment may conflict with a claimed holiday. Emails about moving possessions may suggest an intention to remain permanently. Wedding arrangements or conversations about adjusting immigration status may cause an officer to question whether a stated temporary visit is genuinely temporary. A person describing a business meeting may face difficulty if messages suggest an intention to perform productive work for an American company.

None of those facts automatically establishes an immigration violation. Messages may be misunderstood, taken out of context or written by another person. But contradictions invite further questioning. At the border, digital communications can function much like statements made during an interview.

CBP may scroll through the phone—or conduct a deeper examination

CBP’s electronic-device search directive distinguishes between basic and advanced searches.

A basic search generally involves an officer manually examining information stored on the device—the digital equivalent of scrolling through messages, photographs, emails, contacts or applications. CBP policy allows basic searches without individualised suspicion. They accounted for approximately 92 percent of the agency’s electronic-device searches in fiscal year 2025.

An advanced search is more intensive. It involves connecting external equipment to the device, through a wired or wireless connection, to copy or analyse its contents. Under CBP policy, an advanced search generally requires reasonable suspicion that the device contains evidence of a violation of a law enforced or administered by CBP, or a national-security concern. Supervisory approval is also required.

The legal distinction is important. To a traveller waiting in secondary inspection, however, it may offer limited comfort. An officer does not need advanced forensic software to discover a damaging contradiction. A manual review of several recent messages, photographs or emails may be enough to raise questions about employment, residence, relationships or the true purpose of travel.

Travellers should also understand that being referred to secondary inspection does not automatically mean admission has been denied. CBP may need additional time to verify identity, review records or resolve a discrepancy. But the process can last hours, connecting flights may be missed and access to luggage or a telephone may be restricted.

The safest response is to remain calm and answer the question being asked. Guessing, embellishing or changing an answer merely because an officer appears dissatisfied can create a more serious problem than the underlying fact. An honest “I do not know” is preferable to an invented explanation.

Refusing to unlock the device can have consequences

CBP may ask a traveller to unlock a phone or provide a passcode. The traveller may decline, but a foreign national requesting admission should understand the possible consequences.

The agency may retain the device for further examination. Questioning may continue. More importantly, the officer may conclude that the traveller has not provided enough information to establish admissibility. A visitor may therefore be refused entry even when declining to provide access is not itself being prosecuted as a criminal offence.

That is different from the position of a U.S. citizen, who ordinarily cannot be excluded from the United States. A visitor is seeking permission to enter and generally bears the burden of establishing eligibility.

This does not mean travellers should surrender every password without understanding what is being requested. A phone may contain confidential business records, medical information, intimate family communications, journalistic sources or exchanges with a lawyer. But the decision should not be made under the mistaken assumption that the visa has already guaranteed admission.

CBP publishes an electronic-device search information sheet for travellers explaining its authority, the possible detention of devices and the consequences of failing to present a device in a condition that permits inspection. Anyone carrying unusually sensitive information—or anticipating serious immigration questions—should review the rules and seek advice before travelling. The airport inspection room is a poor place to confront the issue for the first time.

The cloud may not protect what appears on the phone

Under CBP policy, officers generally search information resident on the device rather than using the device to retrieve material stored only on a remote cloud service. Before beginning a search, they are instructed to disconnect the device from networks, such as by activating airplane mode and disabling Wi-Fi and Bluetooth.

That protection is narrower than it may sound. Phones frequently retain recent emails, messages, photographs, downloaded documents, browser history and application data locally. Information may remain visible or searchable even when the device is offline.

Travellers should therefore understand what is actually stored on the device rather than assuming that everything exists only in the cloud. A corporate file opened before departure, an email attachment downloaded automatically or a recent conversation cached by an application may remain accessible.

The border search may also involve comparison rather than discovery. Since 2019, most immigrant and nonimmigrant visa applicants have been required to provide social-media identifiers used during the preceding five years. Information on a phone may be compared with the applicant’s DS-160 form, prior statements, public posts and other information already available to the government.

A traveller who described one employer, relationship status or purpose of travel during the visa process may face questions if the device appears to tell a different story.

Protect information without creating deception

Travellers have legitimate reasons to protect private information. A company executive should not casually carry an organisation’s entire confidential archive across a border. A physician may possess protected patient information. A lawyer may hold privileged client communications. A journalist may carry source identities. An ordinary traveller may simply prefer not to expose years of personal messages and photographs.

Lawful preparation may include backing up important information before departure, travelling only with devices genuinely needed for the journey and removing unnecessary confidential business records under an established workplace or information-security policy. Some organisations issue dedicated travel devices containing only the material required for the trip. Travellers may also keep emergency contact information, accommodation details and essential telephone numbers on paper in case a device is retained.

This is responsible data minimisation. It is not evidence destruction.

A traveller should never delete, alter or conceal information for the purpose of misleading an immigration officer. A last-minute deletion spree may itself appear suspicious. Lying about removed material can create a fraud or misrepresentation problem more serious than the original message, photograph or document.

The safest digital record is an honest one that is consistent with the visa category and actual purpose of travel. A person who genuinely intends to take a holiday should not carry plans suggesting unauthorised employment. A business visitor should understand which activities are permitted and avoid creating the appearance of entering the American labour market. Someone with a complicated relationship, employment or immigration history should obtain advice before departure rather than attempt to improvise an explanation at the airport.

Sensitive information should be identified before it is opened

A device does not become exempt from inspection merely because it contains confidential information. CBP’s directive does, however, establish procedures for material asserted to be protected by attorney-client privilege or the attorney work-product doctrine.

A traveller carrying such information should identify it clearly before the officer reviews it and request that the agency’s privilege procedures be followed. Specificity matters. Saying, “This folder contains communications with my lawyer seeking legal advice,” is more useful than simply declaring that everything on the phone is private.

Commercial, medical and journalistic material may also warrant special handling, although it is not automatically immune from inspection. The concern should be raised before the material is opened, not after it has already been reviewed.

Travellers carrying employer-owned devices should understand their organisation’s policies before departure. Some employers require immediate notification if a government official requests access. Others restrict the international transport of trade secrets, personal data or regulated information. Those procedures should be understood in advance rather than discovered during an airport interview.

If CBP keeps the device, obtain documentation

CBP may temporarily retain a phone, computer or other device when further examination is considered necessary. The agency’s directive generally anticipates that detention should not exceed five days unless additional supervisory approval is obtained. More extended retention requires progressively higher authorisation.

If officers retain a device, the traveller should request written documentation identifying the property, the office holding it and the process for obtaining its return. After the encounter, the traveller should record the airport, date, duration of questioning, questions asked, documents signed and officers’ names or badge numbers when available.

People who experience repeated or apparently mistaken screening may seek assistance through the Department of Homeland Security Traveler Redress Inquiry Program, which serves as the government’s central process for travel-screening complaints and redress requests. Concerns about CBP conduct may also be submitted through the agency’s official complaint system.

A traveller who has been refused admission, allowed to withdraw an application for admission or placed in expedited removal should obtain the relevant records and legal advice before attempting another journey. The legal consequences can extend far beyond the device search itself.

Ghanaian travellers remain subject to ordinary border scrutiny

Ghana does not currently appear on the State Department’s visa-bond country list or its nationality-based B-1/B-2 suspension list.

That is important, but it does not exempt Ghanaian travellers from ordinary CBP inspection or electronic-device searches. The country’s high B-visa refusal rate also makes a border problem especially costly. A traveller denied admission may lose a hard-won visa and encounter substantial difficulty obtaining another one.

A finding that the traveller intended unauthorised employment or permanent residence may damage future visa applications. An expedited-removal order commonly creates a five-year bar to returning. A finding of fraud or material misrepresentation can create a potentially permanent ground of inadmissibility.

The phone search may last only minutes. Its immigration consequences may last years.

Most Ghanaian travellers will enter the United States without having a device searched. Most airport questioning will remain routine. The purpose of preparation is therefore not panic. It is consistency.

Before travelling, visitors should understand what their visas permit, know what information they are carrying and consider whether their messages, documents or planned activities could reasonably conflict with the purpose of entry they intend to present.

They should protect sensitive information lawfully. They should answer questions truthfully. And when the immigration history or proposed journey is complicated, they should seek advice before boarding the plane.

At the American border, a phone is no longer merely an item in the luggage.

It can become testimony.
