What citizens need to know about reentering the US
Returning to the U.S. from a trip abroad and going through the customs process can be stressful and time-consuming on the best of days. But a recent rise in instances where travelers have been stopped for additional questioning or searches by border agents has many travelers understandably wondering about their rights and what they should expect when reentering the U.S.
It’s important to note that the vast majority of U.S. citizens returning to the country get through customs without issue or incident. However, being stopped can happen to anyone. During a recent work trip, a TPG employee was stopped while traveling home through Newark Liberty International Airport (EWR).
After going through Global Entry without issue, a plainclothes officer who wasn’t wearing an easily identifiable badge pulled them aside to talk. He repeatedly questioned their legal status (even after they confirmed their U.S. citizenship) and demanded to see their passport. They were questioned extensively about their trip, their baggage, where they lived and more. While they were eventually let go without being officially detained or searched, they described the interaction as “a really traumatizing experience, especially having my citizenship questioned.”
“You start to think of worst-case scenarios like being deported even though this is your country,” they said. “As someone who travels often for work, it left me uneasy about future trips.”
As the Trump administration continues to target U.S. entry points with increased searches, detentions and even deportations, it’s important to know your rights as a U.S. citizen and how you can protect yourself.
Can a US citizen be stopped at the border?
U.S. Customs and Border Protection officers are allowed to stop anyone, including U.S. citizens, at the border to determine whether someone can lawfully enter the country. Officers can also search belongings for illicit materials (such as narcotics or other contraband). This can look like being pulled aside to answer additional questions, bag searches, device searches or — in extreme cases — even additional physical searches.
CBP claims that travelers don’t have the right to an attorney during these inspections.
While U.S. citizens are subject to CBP inspections, they cannot be denied entry into the country. According to the American Civil Liberties Union, “If you are a U.S. citizen, you need only answer questions establishing your identity and citizenship, although refusing to answer routine questions about the nature and purpose of your travel could result in delay and/or further inspection.”
Keep your passport easily accessible until you leave the airport, just in case you are stopped to answer additional questions about your identity and citizenship. If you are especially concerned about being stopped or potentially even detained, it’s not a bad idea to have the name and number of a lawyer written down in case of emergencies.
Can CBP agents search your phone or other devices?
The U.S. government states that the search of cellphones, laptops or other electronic devices falls under the same authority as general searches for contraband. Some organizations, such as the ACLU, state that device searches are a “contested legal issue,” and there are a variety of court cases in different states that set some limits for device searches at the border. However, given that there is no national standard from the Supreme Court or Congress, CBP currently operates under the belief that device searches are permissible in order to protect national security and prevent contraband from entering the country.
U.S. citizens are not required to unlock their devices for officers or provide any passwords. However, border agents can confiscate those devices for further inspection if you do not comply, and you may be subject to additional questioning and delays getting through customs. If your devices are seized for any reason, make sure to get a receipt for your property. Your confiscated devices should be returned to you by mail.
According to the CBP website, officers may perform a basic device check done manually by a border agent or a more advanced search done with special equipment. Advanced searches require a reasonable suspicion of a crime or national security concern, and a senior CBP manager has to sign off. The CBP claims “less than 0.01 percent of arriving international travelers encountered by CBP at a port of entry had their electronic devices searched” in 2024.
While increased coverage of device searches (and the decisions made by border agents after these searches) has certainly highlighted increased concern about the Trump administration’s handling of the balance between border security and individual liberty, Deputy Director of the ACLU Speech, Privacy, and Technology Project Esha Bhandari pointed out in a recent ACLU At Liberty podcast that device searches are not unique to the current administration.
“These device searches have been done across administrations, and they’ve been rising across administrations,” Bhandari said. “But I think we’re seeing renewed attention now because of this sense that the government might use these impermissible factors, these impermissible reasons, to exclude people just because they don’t like how they think or express themselves.”
Should you be concerned about digital privacy when traveling?
The stories about device searches getting the most coverage in the news have involved non-U.S. citizens. So some travelers who are citizens may wonder: Should I care about digital privacy when traveling if this isn’t currently affecting most U.S. citizens?
Your devices are essentially a digital lockbox of everything you’ve ever said or done. They can provide access to highly personal information that you may prefer to keep private — be it demographic information, your religious and political beliefs, health information, work conversations, or even just your hot takes on the newest season of “The Last of Us.”
“It’s one thing to say, you know, ‘We got a warrant and we’re looking for a very particular limited thing for something we’re investigating,'” said Bhandari. “But if you’re just rummaging through, think about how much is subject to misinterpretation. Think about how much is gonna be seen out of context.”
It’s not irrational to want to keep your digital data private whenever possible, and U.S. citizens have a right to that privacy from the government in the form of protection against unreasonable searches and seizures. While the U.S. government may consider device searches (with or without a warrant) at the border a reasonable search, it’s fair to be concerned about any entity — including the U.S. government — having full access to private data that can be weaponized against you or people you are connected to.
How to protect your privacy when reentering the country
If you are concerned about protecting your data and privacy in this era of increased border inspections and political uncertainty, here are a few simple things you can do when traveling.
Travel with as few devices as possible
One easy way to protect your privacy on your devices when you travel is to simply not take them.
“If you don’t have information on you when you cross the border, they can’t search it,” said Daniel Kahn Gillmor, senior staff technologist at the ACLU, in the same At Liberty podcast.
Leaving everything behind may not be feasible, especially in an increasingly digital world where many of us communicate, navigate, take photos and even pay for things with our smartphones. But take stock of what you are bringing with you. If you are going on vacation, maybe you choose to leave your work laptop at home. Instead of taking your iPad for entertainment, pack an extra book or a device with less personal information on it (like a Kindle or gaming device kept in airplane mode).
Use encryption and remove biometric access to your device before traveling
Your smartphone likely has basic encryption via Android or iOS, but ensure all of your devices have encrypted storage (which will also protect you during your travels from other cyber concerns, so it’s a win-win). Gillmor warns that your devices’ encryption is only as strong as your passcodes.
U.S. citizens are not required to hand over passwords to unlock a device, but you can be compelled to use your biometrics. Turn off Face ID, remove fingerprint access and use a strong, unique passcode to lock your devices. If your phone’s passcode is 000001 or your spouse’s birthday, it might be time to change it.
Keep your devices on airplane mode when entering the country
Border agents are not supposed to search cloud-stored data; searches are only meant to access what is downloaded onto your devices’ hard drives. Keeping your devices in airplane mode with Wi-Fi and Bluetooth disabled and disconnected from the cloud until you leave the airport can add an extra layer of privacy protection if you are pulled aside for a search.
If you are subjected to a device search, the CBP website states an officer should request that you turn these features off before the search. But if you have privacy concerns, it’s best not to take any chances and have those features disabled before going through security.
Remove sensitive data from your devices before you travel
If you are concerned about specific information on your devices — photos, sensitive work information, private conversations, etc. — you might consider downloading that information to an encrypted external hard drive that you leave at home during your trip and then deleting it from your devices (make sure you delete these items fully, as sometimes devices have a temporary trash where items remain for a certain time frame).
You can also take extra steps such as logging out of your iCloud, Google or Outlook accounts to temporarily restrict what personal, private information is easily accessible via your devices.

Bottom line
While hundreds of thousands of individuals enter the U.S. daily without any complications, you never know when you might be pulled aside for additional questioning or searches. Reports of border agents stopping U.S. citizens — especially immigrants and members of minority groups — have increased since the Trump administration took office.
Have a plan for what you might do if approached for additional questioning or a device search. Will you plan to consent to a device search and hand over passcodes, or will you refuse and accept the possibility of your devices being confiscated and mailed back to you at a later date? If you are detained for any reason, do you have the number of a lawyer you can call? If you’re concerned about your digital privacy while going through a U.S. port of entry, the steps above can help protect you and your private data.
