Does it apply to non-citizens?

As far as I know, in the US you can politely decline a phone search if you are a US citizen. If you're a foreign tourist your only choice is either to allow the search or be denied entry to the Land of Freedom™

How does it work in Australia?

[jkaplowitz]

At the US international border, no, even US citizens can’t prevent the phone search regardless of whether or not they consent. They can however usually decline to give a PIN, passcode, or password or to assist in unlocking the phone by entering such a credential, and they can’t be refused entry to the US. However, CBP can then temporarily seize the phone to perform a more comprehensive attempt at searching it. Getting the phone back later may be a hassle.

Additionally, pissing off CBP may lead to extended delays, luggage searching, and questioning to see if they can find another legally valid reason to punish you for annoying them. And maybe they might revoke trusted traveler program membership due to no longer seeing you as a low-risk traveler. But indeed, they will not finally refuse entry to a citizen.

There are rarer cases where the US government can insist on your cooperation in getting past a PIN, passcode, or password, such as if you show them that an incriminating document exists on your phone and then lock the phone before they can collect the evidence.

And while the exact boundary of the constitutional protections regarding face or fingerprint unlock is not authoritatively settled nationwide in the courts, it’s very likely weaker than for information you hold in your mind like a password.

I strongly suspect CBP can constitutionally require a US citizen entering at an international port of entry to assist with fingerprint or face unlock, though I admit I don’t know how physically they can force the matter if the person refuses. It wouldn’t surprise me if that would be grounds for arrest under at least some circumstances (maybe not all).

While I was born after 9/11, I'm think I've heard that these unprecedented powers were given to CBP (and other border agencies around the world) after that event.

Most people crossing any border face little friction like this, but when you dig in and see what border agents are allowed to do, it gets a bit unnerving. Especially so for the US, the self-proclaimed land of the free.

Consider this - the CBP is granted wide-reaching powers that can supersede what actual police are allowed to do. They're allowed to racially profile, discriminate, search or detain anyone for any reason - citizen or not. Search warrants aren't required. Punishments like refusing foreigners entry for no reason or marking citizens to be additionally screened for the rest of their life can't be contested and are absolute. They are insulated from being sued, and may not need to follow Freedom of Information requests (not sure if this was reverted or not). They can do any of this within 100 miles of any external US borders - a.k.a. most major cities in the country. You don't actually need to be crossing or have crossed a border to be held up. Freedom!

The more you read into it, the more it seems that the federal US government has written a black check in terms of what some people are allowed to do. In the vast majority of cases, border guards are reasonable and don't overstep any boundaries - but I'm confused at why Americans, with the culture of valuing individual freedoms over all, aren't concerned with the hypothetical consequences these powers provide.

As the article states, they can take your phone and try to hack it, but they can't otherwise punish you for refusing to give them your password.

>they can't otherwise punish you for refusing to give them your password.

Except of course by denying you entry, marking you in some "no fly" blacklist, and other ways that are not oficially "punishments", but are very much so in practice...

[alexey-salmin]

They can refuse entry at any time, and legally speaking it's not punishment

Same with being filmed at the airport. Last time I passed through US airports there were signs that you're monitored and it goes to blah blah database, and that if you're a US citizen, you can request to be removed. If you're not, go fuck yourself and pray all your biometric data isn't stored at the cheapest possible vendor and about to be leaked.

And would anyone be surprised if asking to be removed was also a way to get subjected to additional screening in future?
