Crossing into the United States has become riskier since the start of Trump’s second administration. Foreign visitors and US visa holders are increasingly being detained, questioned, or deported. As uncertainty grows, travel demand from Canada and Europe has dropped sharply.
Regardless of why you are traveling, US Customs and Border Protection (CBP) has the authority to search phones and other electronic devices at the border.
While other countries also inspect devices, the volatile US policies have led travelers and companies to reconsider what they carry. Canada has issued travel warnings, and journalists are advised to prepare for device searches.
At the border, CBP can demand PINs or biometrics to unlock devices. US citizens and green card holders can refuse without being denied entry, although this may trigger additional questioning or device seizure. Visa holders and visitors, however, face detention or deportation if they refuse a search. Travelers must assess their own risk based on legal status, nationality, profession, and online activity.
To minimize risk, disable facial recognition or fingerprint unlock before traveling and use only a PIN. Update your phone’s software to make it harder to crack. Carry a paper boarding pass and keep your phone off or out of sight when approaching agents.
One strategy is to travel with a separate device, either by wiping an old phone or buying a new one. Build a limited digital footprint on the travel phone—use separate emails, social media accounts, and encrypted messaging apps like Signal.
However, the device should not appear suspiciously clean; normal usage should be simulated to avoid drawing attention.
Another option is to clean your primary phone before traveling by backing up and deleting sensitive data and unnecessary apps. After returning, you can restore your phone from backup. However, mistakes in this process can leave traces of personal information vulnerable during inspection.
Even if you don’t make major changes, basic steps like deleting old apps, updating software, limiting social media use, and keeping important documents printed can protect your privacy.
Experts warn that travelers should assume border agents may scrutinize online presence and past posts.
As device searches become more common at US borders, preparing ahead of travel has become critical for safeguarding personal information.
