Every person who arrives in the United States — citizen, green card holder, visa holder, or visitor — passes through inspection by an officer of U.S. Customs and Border Protection. For most travelers this takes ninety seconds. For some it takes six hours in a windowless room, and the difference is rarely something the traveler saw coming.

The port of entry is one of the few places in American life where ordinary constitutional protections are at their weakest. Officers may search your luggage without a warrant. They may search your phone without a warrant. They may ask you almost anything. Understanding what is routine, what is unusual, and where the actual limits sit is the difference between an inconvenience and a lost immigration status.

This post covers what happens during inspection, what changed in 2026, what your rights are depending on your status, and — the question we now get more than any other — what officers can and cannot do with your phone.

Part One: What Inspection Actually Looks Like

Primary inspection

This is the booth. An officer reviews your passport and travel document, takes your fingerprints and photograph, runs your name against federal databases, and asks a handful of questions about who you are and why you are here. Most travelers are admitted here and go collect their bags.

Secondary inspection

If the officer cannot resolve something quickly — a name that resembles a database hit, an answer that does not match your visa, a long absence from the country, an old arrest — you are directed to a separate area for a longer interview. In secondary, officers may review your documents in detail, question you at length, search your luggage, run deeper records checks, and examine your electronic devices.

Being sent to secondary is not a denial. Every new immigrant arriving for the first time on an immigrant visa goes to secondary as a matter of routine, so that an officer can process the file. Secondary can last twenty minutes or the better part of a day.

Deferred inspection

Occasionally CBP admits a traveler but requires them to report to a deferred inspection site later to resolve a documentary problem. This is a real appointment with real consequences. Do not miss it, and consider bringing counsel.

Part Two: Three Things That Changed Recently

If you are working from a travel guide written before 2026, three parts of it are now out of date.

3. Biometrics are now universal for noncitizens. A DHS final rule effective December 26, 2025 authorizes CBP to photograph every noncitizen on both entry and departure, at airports, land ports, and seaports. Exemptions that used to cover diplomats, most Canadian visitors, children under 14, and adults over 79 were removed. Photographs of U.S. citizens are discarded within twelve hours; photographs of noncitizens — including lawful permanent residents — are retained in DHS’s biometric identity system for up to 75 years. U.S. citizens may opt out and request manual passport inspection.
4. CBP has a new electronic device directive. On January 1, 2026, CBP Directive 3340-049B replaced the 2018 directive (3340-049A) that most published guidance still cites. It is covered in detail below.
5. Social media review has expanded well into family-based categories. The State Department extended “online presence review” to F, M, and J applicants in June 2025, to H-1B and H-4 in December 2025, and — effective March 30, 2026 — to a much wider list that now includes K-1, K-2, and K-3 applicants, along with R, Q, S, T, U, H-3, A-3, C-3, and G-5. Affected applicants must disclose five years of social media handles on the DS-160 and set their profiles to public through adjudication. Separately, a nationwide entry proclamation issued December 16, 2025 restricts entry for nationals of 39 countries, effective January 1, 2026.

None of this changes the law of inspection. All of it changes how much the government knows about you before you reach the booth.

Part Three: The Questions

Officers may ask nearly anything relevant to admissibility. The predictable ones:

• Everyone: Where do you live? Why are you traveling to the United States? How long will you stay? Where will you be staying? Who are you visiting? Have you been arrested or convicted of anything? Do you have anything to declare?
• Green card holders: How long were you outside the country? Why? Where is your primary residence? Have you been working abroad? Do you have your green card with you?
• Visitors (B-1/B-2, ESTA): Have you been here before, and for how long? How often do you come? Who is paying for the trip? What do you do in your home country? Do you have a return ticket? Do you intend to work or study while you are here?
• Students (F, M, J): Which school? What program? May I see your I-20 or DS-2019? Are you returning to resume classes?
• Employment visa holders: Who is your employer? What are your duties? Where is the worksite? May I see your approval notice?
• Asylees and refugees: May I see your travel document? Where have you traveled? Have you returned to your country of feared persecution?

The single organizing principle: your answer must be true, and it must be consistent with the status you are asking to enter under. A B-2 visitor who mentions a job interview has just described a visa violation. A returning resident who says the family relocated to Guadalajara last year has just described abandonment. Officers are trained to look for exactly this.

Part Four: Your Rights Depend Entirely on Your Status

This is the part most travelers get wrong. “Know your rights” at the border is not one answer. It is four.

If you are a U.S. citizen

You cannot be denied entry. That is the whole of it, and it is a great deal. You must establish your citizenship, and you may be detained, questioned, delayed, and have your belongings searched. But once your citizenship is established, you must be admitted. You may decline to answer questions beyond identity and citizenship; doing so may lengthen the encounter but cannot cost you entry.

If you are a lawful permanent resident

A returning LPR is generally treated as a returning resident — not as someone applying for admission — and is admitted without being tested against the grounds of inadmissibility.

That protection falls away, and you become an “arriving alien,” only under the six conditions in INA § 101(a)(13)(C): you abandoned or relinquished status; you were absent more than 180 continuous days; you engaged in illegal activity after leaving; you departed while in removal or extradition proceedings; you committed an offense described in INA § 212(a)(2) without a waiver; or you attempt to enter without inspection.

Two things follow, and they matter enormously:

• LPRs are generally not subject to expedited removal. If CBP believes you are inadmissible, it must issue a Notice to Appear and let an immigration judge decide. An officer at a counter cannot terminate your residency.
• Form I-407 is voluntary. Officers sometimes present the Record of Abandonment of Lawful Permanent Resident Status to travelers who have been abroad a long time, occasionally with the suggestion that signing will simplify things. It will not. Signing surrenders your green card, and it is extremely difficult to undo — including when it was signed at 2 a.m. after a fourteen-hour flight. You are not required to sign, and there is no penalty for refusing.

If you decline, CBP must proceed through immigration court, where the government carries the burden of proving abandonment by clear, unequivocal, and convincing evidence — a standard it frequently cannot meet. That is your leverage. Do not give it away.

If CBP takes your physical card, ask them to stamp your passport as evidence of status. If they refuse, you can schedule a USCIS appointment for an I-551 stamp.

If you hold a nonimmigrant visa, or travel under ESTA

Your protections are thinnest here. A visa is permission to request admission, not a right to enter. If an officer concludes you are inadmissible or intend something other than what your visa permits, you can be refused on the spot through expedited removal under INA § 235(b)(1) — which carries a five-year bar — or you may be offered the chance to withdraw your application for admission, which avoids the formal removal order and the bar. Withdrawal is discretionary; CBP does not have to offer it, and you cannot demand it.

Visa Waiver Program travelers have signed away the right to contest removal in most circumstances as a condition of using ESTA. The exception is asylum.

If you are seeking protection

If you fear persecution or torture in your country, say so to the officer. Expressing that fear should trigger a referral for a credible fear interview rather than summary return. Say it clearly, say it early, and say it even if you are frightened.

One universal limit

There is no right to have an attorney present in primary or secondary inspection (8 C.F.R. § 292.5(b)). Ask anyway — the request goes on the record. The right to counsel attaches once you are in removal proceedings. Foreign nationals who are detained may request notification of their consulate.

You are also not required to answer questions about your political beliefs, religious practice, or associations. Officers sometimes ask. You may decline. For nonimmigrants, understand that declining may prolong the encounter and, in the officer’s discretion, contribute to a refusal.

Part Five: Cell Phones, Laptops, and the Border Search Exception

Why they can do this at all

Courts have recognized for over a century a border search exception to the Fourth Amendment’s warrant requirement. Routine searches of persons and property at the border are reasonable simply because they occur at the border. Every federal appellate court to consider the question has extended that exception, in some form, to electronic devices.

The Supreme Court’s 2014 decision in Riley v. California — holding that police need a warrant to search a phone incident to arrest — did not resolve this. Litigants have argued Riley’s logic should control at the border. No federal circuit has yet required a warrant for a border device search.

What CBP’s current policy says

Under Directive 3340-049B, effective January 2026, CBP distinguishes:

The 2026 directive expands the definition of “electronic device” to reach flash drives, SIM cards, GPS units, smart watches, drones, and vehicle infotainment systems.

Within that framework, CBP’s own policy imposes limits:

• Cloud-only data is off limits. Officers are to examine only what resides on the device, and are directed to disable network connectivity (or ask you to) before searching. A passcode may not be used to reach information stored solely remotely.
• Travelers must present a device in a condition that allows inspection. Officers may request your passcode, which policy says is deleted after the search.
• Detention of the device. Holding a device beyond five days requires supervisory approval; beyond fifteen days requires higher-level approval, renewable in seven-day increments. Ask for a property receipt — CBP Form 6051D — and write down the officer’s name and badge number.
• Retained data. Absent probable cause or another lawful basis to keep it, copied information is to be destroyed within 21 days.
• Privileged and sensitive material. Special handling procedures apply to attorney-client and work-product material, journalistic material, medical records, and business confidential information. If your device contains privileged material, say so before the search begins, identify the files or folders, and ask that the segregation procedure be followed.

Two cautions about that list. First, the directive binds CBP, not ICE or Homeland Security Investigations, whose agents exercise the same border search authority under their own policies. Second, the directive expressly creates no private right — it is internal policy, not an enforceable set of rights.

How constitutional law actually stands

Where you land determines what the Constitution requires:

• First and Eleventh Circuits: No warrant and no individualized suspicion, even for forensic searches (Alasaad v. Mayorkas; United States v. Touset).
• Fourth and Ninth Circuits: Forensic border searches of electronic devices are nonroutine and require individualized suspicion. In the Ninth Circuit, such searches require reasonable suspicion. United States v. Cotterman; United States v. Cano). Cano further holds that the reasonable suspicion must be directed to digital contraband contained on the device and that the border-search exception does not authorize a general search for evidence of criminal activity. The Fourth Circuit likewise classifies forensic phone searches as nonroutine and requiring individualized suspicion, but has not decided whether reasonable suspicion alone is constitutionally sufficient. United States v. Kolsuz.
• A district court in the Southern District of New York has required a warrant (United States v. Smith, 2023). No appellate court has followed.

Arizona sits in the Ninth Circuit. Travelers arriving at Phoenix Sky Harbor, Tucson International, or the land ports at Nogales, San Luis, Lukeville, or Douglas are in a jurisdiction where a forensic search of a device requires reasonable suspicion, and where the permissible scope of that search is narrower than in most of the country. That is a meaningful protection, and it is currently under active reexamination — appeals raising the warrant question are pending in the Third Circuit (United States v. Roggio) and the Fourth Circuit (United States v. Belmonte Cardozo, argued May 2026). A circuit split on the warrant question would put the issue squarely before the Supreme Court.

What happens if you refuse to unlock

Refusal is not, by itself, a crime. But the consequence tracks your status:

• S. citizens cannot be denied entry for refusing. The device can be seized and held.
• Lawful permanent residents cannot have residency revoked at the counter, but refusal will likely mean a longer detention and seizure of the device, and it may become part of an inadmissibility record.
• Nonimmigrants and ESTA travelers can be refused entry. There is no meaningful protection here. Refusal may functionally end the trip.

Scale

In fiscal year 2025, CBP conducted 55,318 device searches — basic and advanced combined. Against total arrivals, that remains a small fraction of one percent of travelers. It is also a number that has climbed every year.

Practical steps

Travel with what you need and nothing more. A device carrying less data is a device with less to search.

• Consider a clean travel device for high-risk trips.
• Log out of email, messaging, and social media apps, or remove them, before you cross. Reinstall afterward.
• Keep sensitive material in the cloud rather than on the device, and turn off automatic sync before travel.
• Put the device in airplane mode before handing it over.
• Do not wipe your device or delete your accounts on the way to the airport. Deleting content in anticipation of inspection can be read as concealment, and can raise fraud concerns far worse than whatever you deleted.

Part Six: The Things That Cannot Be Undone

Most bad outcomes at a port of entry are recoverable. These are not.

Lying to a federal officer. Misrepresentation of a material fact to procure admission triggers inadmissibility under INA § 212(a)(6)(C)(i). A waiver exists, but it requires a qualifying relative and extreme hardship.

Falsely claiming U.S. citizenship. Under INA § 212(a)(6)(C)(ii), this is a permanent bar with no waiver for most people. Say nothing rather than say this.

Signing Form I-407. Discussed above. It ends your residency by your own hand.

Signing anything you have not read and understood. Ask for an interpreter. Ask for time. Read it. Do not rely on an officer’s verbal summary of a document’s legal effect.

Part Seven: Before You Travel

• Carry the documents that prove the status you are claiming: passport, visa or green card, I-20 or DS-2019, approval notices, reentry permit.
• Green card holders returning from a long absence should carry evidence that life is centered here: U.S. tax returns, lease or mortgage, pay stubs, utility bills, children’s school records, bank statements.
• Do not carry anything that contradicts the status you are entering under.
• Check your I-94 online shortly after arrival to confirm your class of admission and admit-until date. Errors are common and are far easier to fix early. (A fee now applies to Form I-94 issuance at entry — confirm the current amount before you travel.)
• Leave a copy of your itinerary and an attorney’s contact number with someone at home, on paper.
• Consult counsel before traveling if you have any arrest or conviction, a pending USCIS or immigration court matter, a prior removal, a long absence, conditional residence, or any prior difficult encounter with CBP.

Part Eight: If It Goes Wrong

• Stay calm and be polite. Nothing good comes from an argument at a border counter.
• Do not lie. If you do not want to answer, say you do not want to answer.
• Ask for a lawyer. You will likely be told no. Ask anyway, so the request is on the record.
• Do not sign anything without legal advice.
• If a device is taken, get the Form 6051D receipt and the officer’s name and badge number.
• Write down what happened — times, names, what was asked, what was said — as soon as you can.
• Call an immigration attorney immediately. In a port-of-entry matter, the first hours are the ones that count.
