With increasing news that US border bureaucrats are asking travellers to hand over electronic devices and provide access (passwords etc.), so they can check your social media, email and so on, it is time either to give the USA a miss (there are better places to visit) or to leave all devices at home. A simple ‘dumb’ or ‘burner’ phone, with a couple of numbers on it may be all that you want to bring with you. Then again, you may be denied entry with these as well, since they may be a signal you are trying to hide something.
In all this, the one I like best is that one may be subject to ‘ideological’ questioning upon arrival at the border.
