"U.S. Customs and Border Protection (CBP) states on its website that it "reserves the right to search electronic devices" of people arriving in the country. Still, it is unknown whether or not this policy extends to checking the contents of phones or other electronic devices.
A recent report by The Intercept suggests that CBP may be searching the phones of some international travelers without a warrant or any suspicion of wrongdoing and that some travelers have had their phones seized for weeks or months at a time.
If you're traveling internationally, it's best to assume that your phone will be searched and to take steps to protect your data by encrypting your device and/or removing sensitive information."
