How to Protect Your Data – and Avoid Trouble.
A Practical Guide for Travelers in the Age of Surveillance and Suspicion.
Repression often begins quietly: first, Mahmoud Khalil was taken from his home in New York. Then, attention turned to politically active immigrants. Eventually, border agents began systematically searching mobile phones—often without a court order, but always under the banner of “national security.”
Even before Donald Trump’s second inauguration in 2025, electronic searches at U.S. borders were steadily rising. Since taking office, the practice has intensified: political opinions, social media profiles, and stored contacts have become unofficial components of the entry screening process. This guide is designed to help protect your digital identity while offering practical tips on how to prepare physically and mentally to avoid unnecessary confrontation.
1. Understand the Law
U.S. border agents claim broad authority, applicable regardless of immigration status. Even U.S. citizens can be asked to hand over devices. While citizens may decline to provide passwords or PINs, doing so could result in delays or device confiscation.
Officially, agents aren’t supposed to access cloud-only data. In practice, they may put phones in airplane mode—but travelers shouldn’t rely on that. What matters most is knowing your rights and asserting them calmly.
2. Prepare Your Travel Documents
Check your passport’s expiration date.
Keep all flight documents and also retain documentation for your departure from the U.S.
Have hotel confirmations or at least an address where you’ll be staying.
Complete all entry forms legibly and double-check for accuracy.
Do not provide false information about your travel plans or purpose of entry.
An international driver’s license may be useful if you plan to drive; in most cases, your national license will suffice.
These documents help demonstrate that your travel is well-planned, which can reduce suspicion.
Tip: Carry the contact number for the German embassy or consulate in the U.S.
3. Behavior at the Border
Avoid political discussions. U.S. agents often have limited context for European political debates.
Don’t deliver monologues. Excessive talk can appear suspicious.
Maintain respectful physical distance.
Stay calm. Nervousness increases the chance of a search.
Follow instructions without argument, even if agents seem rude.
Do not get involved in other travelers’ immigration issues—you likely can’t help and may put yourself at risk.
If you don’t speak fluent English, install a translation app before traveling.
4. Prepare Your Devices
Use separate devices for travel; leave your usual phone at home.
Log out of all accounts. Delete apps if necessary.
Power down all devices before arriving at a checkpoint.
Disable biometric access: turn off fingerprint and facial recognition features.
5. Protect Your Data
Avoid storing sensitive data on your phone. Use encrypted cloud services and download data only after entry.
Back up devices securely with tools like iCloud’s Advanced Data Protection.
Review and remove contacts who may raise red flags—especially activists or journalists.
6. High-Risk Travelers: Advanced Security
Leave your SIM card and phone number at home. Use a temporary number while abroad.
Avoid SMS-based two-factor authentication. Use authentication apps instead.
Final Note
Crossing the border is no longer a private matter. Anyone entering the United States should be aware that digital data has long become a tool of government surveillance — and that under Donald Trump, entry procedures have become drastically more restrictive. But with the right preparation, technology, and mindset, risks can be minimized — and personal sovereignty, at least in part, can still be preserved." Stay informed. Stay composed. Travel smart.
