I’m traveling to the US mainland for the first time in my life in a few weeks.
I am not overly stressed about privacy, but I have read that US immigration can really overstep their boundaries. Are there any simple specific steps to take on my devices to protect my privace when going through US border control?
Remove my main accounts from my phone/tablet and use dummy accounts? Or just removing my biometrics?
Wipe your phone, restore from backup once you’re in.
This is actually the best answer here. It’s a good habit for any border crossing.
