The Fourth Circuit ruled today in United States v. Belmonte Cardozo that a border officer can pick up your phone, unlock it if you hand over the passcode, and scroll through your photos, messages, and apps without a warrant, without probable cause, and without any suspicion that you did anything wrong. This is now the law in North Carolina, South Carolina, Virginia, Maryland, and West Virginia.
Here is what that means the next time you fly home from vacation.
The border search exception is old and broad. Since the founding, the government has been allowed to inspect people and property entering the country without a warrant. Courts extended that authority to the functional equivalent of the border, which includes every international airport. Charlotte, Raleigh, Dulles, and every seaport and land crossing in the country. Your expectation of privacy is lower there than anywhere else, and the Supreme Court has said so for decades.
For years the open question was whether your phone is different. The Supreme Court held in Riley v. California that police need a warrant to search a phone after an arrest. The Fourth Circuit had already ruled in United States v. Kolsuz that a forensic search at the border, meaning officers plug your device into extraction equipment and copy everything on it, requires at least individualized suspicion. Today the court answered the piece it had left open. A manual search, meaning an officer holding your phone and scrolling through it by hand, requires nothing at all. Routine. No suspicion needed.
That distinction is the whole ballgame. Officer scrolling by hand needs no reason. Officer plugging your phone into a machine needs reasonable suspicion.
This applies to EVERYONE. In the leading case on device searches, Alasaad v. Mayorkas, the eleven people whose phones and laptops were searched were ten United States citizens and one green card holder. A NASA engineer. A journalist. A student. An artist. None was charged with anything. Some got their devices back weeks later.
So know this before your next international trip. Officers can search your phone at any port of entry with no warrant and no suspicion. If you are a citizen, you cannot be denied reentry for declining to unlock it, but they can seize the device and make you wait. If you are a lawful permanent resident, declining carries more risk. If you are on a visa, refusing can cost you entry entirely.
CBP says it can only search what is stored on the device itself, not what lives in your cloud, so logging out of accounts and putting the phone in airplane mode before you land actually matters. The 4th Amendment protects you least at the exact moment you are coming home.
