CBP & Border Questions
What is the '100-Mile Border Zone'?
A federal regulation (8 CFR 287.1) allows CBP to board vehicles and search for aliens without a warrant within 100 air miles of any U.S. external boundary. This includes the entire coastline.
Do I have to answer questions at a checkpoint?
At an internal checkpoint (like on a highway), you must stop. However, you have the right to remain silent. You can say: 'I am exercising my right to remain silent.'
Can they search my phone at the airport?
Yes. CBP claims broad authority to search electronic devices at ports of entry without a warrant. It is best to travel with devices powered off and encrypted.
What if I am a US Citizen?
You cannot be deported. However, you can still be detained if you refuse to answer questions. You do not have to answer questions about your travel or private life, but you must prove your citizenship (passport).
