Travelers beware regardless of your country of origin. I wasn’t aware that, when passing through a U.S. port of entry, CBP can search the contents of your phone without reasonable suspicion. This may include private messages, photos, bank accounts, and cryptocurrency holdings. A precautionary solution is to back up your data, remove sensitive apps before traveling, and reinstall them once you reach your destination. However if after your phone is confiscated for inspection, you erase data, that's a problem, hence 👆. Be prepared. ---- The Second Circuit said a manual phone search at the border is still a “routine” property inspection under existing Supreme Court border-search cases, so no suspicion is required. Judge Lee’s concurrence said that treating a phone that way **erases** your Fourth Amendment protection for the private contents people actually carry. The Supreme Court has not taken *Alisigwe* yet. The opinion is only a week old, so no cert petition is on the docket. Related cases in other circuits have already split on how far the **border exception** goes with electronic devices, which is why lawyers expect the Court to take the issue at some point. Until it does, the Second Circuit rule is the law in that circuit. A later Supreme Court decision could keep that rule, require suspicion, or require a warrant. That is the decision worth waiting for.
