Bringing Your Phone or Laptop Into the U.S.?

Yes, they can look at your device

  • Any CBP officer can do a quick “basic” look through your device — no special reason needed. This can happen to anyone.
  • A deeper “advanced” search (plugging your device into another machine to copy or dig through it) usually needs a specific reason, but officers can now also do this for national security concerns, even without one — as long as a supervisor signs off.

Devices covered — more than you’d think

  • Phones, laptops, tablets, cameras, and media players — plus now flash drives, SIM cards, GPS units, smart watches, drones, and even your rental car’s infotainment system.

What officers can and can’t do with your passcode

  • If your device is locked, an officer can ask you to help unlock it.
  • They may hold your passcode only long enough to finish the search, and it must be deleted afterward — it cannot be saved permanently or used to access anything stored online (like your cloud backups or email on a server).
  • If you don’t unlock it and they can’t get in another way, they can hold onto the device while they figure out next steps.

If your device is taken from you

  • You should be given a receipt (Form 6051D) any time your device is detained, and again if it’s returned or handed to another agency.
  • Officers generally have 5 days before they need extra approval to keep your device longer, and 15 days before they need even higher-level approval — after that, it can be extended in 7-day increments.
  • Your device can only be permanently kept (seized) if officers have real grounds to believe it holds evidence of a crime or prohibited material.

Sensitive material (medical, legal, work files)

  • If you tell an officer that something on your device is privileged or confidential (like attorney, medical, or business records), say so clearly and, if possible, point out which files or folders those are.
  • CBP has a process meant to wall off that material from the rest of the search.

A few practical tips

  • Rules can differ slightly depending on which part of the country you’re entering through — courts in different regions interpret this differently.
  • Consider signing out of accounts or turning on airplane mode before you reach the border if you’re worried about remote/cloud data — officers are not supposed to intentionally search anything stored online.
  • You can ask to be present while your device is searched; officers will generally allow this unless it would interfere with their work.
  •  Keep any receipt (Form 6051D) you’re given — it’s your proof of what was taken and when.
