Traveling to the US? Protect Your Device Data from Border Searches
US Border Device Searches: What Visa and Green Card Holders Need to Know
If you’re a visa or green card holder planning to travel to the US, you may have heard reports of travelers being turned away at airports due to messages found on their devices. These unsettling accounts can make anyone reconsider their travel plans, raising important questions: Can US Customs and Border Protection (CBP) search your phone? Can you refuse? What steps should you take to protect your privacy?
Can CBP Search Your Devices?
The short answer is yes — CBP can search your devices. At US borders, including airports, constitutional protections regarding searches are generally weaker. Refusing a search may lead to confiscation of your devices or extended questioning. For many, the potential consequences of non-compliance can be intimidating.
Assessing Your Personal Risk
Privacy experts advise conducting a personal risk assessment before traveling. Consider factors like your immigration status, travel history, and the type of data on your devices. While CBP reported around 47,000 device searches out of 420 million border crossings in 2024, experts note that enforcement can be unpredictable. A notable case involved a French scientist denied entry after CBP officers found text messages critical of former President Trump.
What Are Your Options?
Deciding whether to comply with a device search is a complex decision. While you have the right to refuse, doing so may lead to further scrutiny. If you comply, you may be asked to unlock your device. Ideally, you should unlock it yourself rather than providing your password. If you choose to resist, be prepared for the possibility of having your device confiscated. Always request a property receipt if this happens.
How to Protect Your Data
To minimize risks, take proactive steps before traveling:
- Turn Off Your Devices: Power down your devices before entering the US. This can enhance encryption and make unauthorized access more difficult.
- Use Strong Passwords: Ensure your devices require a strong, long password instead of biometric access like Face ID or fingerprint recognition.
- Avoid Wiping Devices: Completely wiping your devices may raise suspicion. Instead, selectively delete sensitive data.
- Encrypt Your Data: Most modern smartphones come with full-device encryption. Verify your encryption settings in your device’s security settings.
- Utilize Cloud Storage: Save sensitive data to a cloud service before traveling. CBP is not authorized to search data stored on remote servers.
Deleting Data Securely
If you choose to delete sensitive files, ensure they are removed from trash or “recently deleted” folders. On iPhones, for example, double-check the “recently deleted” folder under iMessage filters.
Navigating Device Ownership
If you’re traveling with a work-owned device, consult your employer about security measures. Ensure that your device complies with company policies while safeguarding your privacy.
The Balance Between Privacy and Compliance
Traveling to the US requires a balance between protecting your privacy and complying with border procedures. While no solution offers total immunity, thoughtful preparation can reduce risks. Stay informed, secure your devices, and make informed decisions to protect your digital privacy while traveling.
