Relevant section on Wikipedia:

The government may not criminally punish immigrants based on speech that would be protected if said by a citizen.[83] On entry across borders, the government may bar non-citizens from the United States based on their speech, even if that speech would have been protected if said by a citizen.[84] Speech rules as to deportation, on the other hand, are unclear.[85] Lower courts are divided on the question, while the leading cases on the subject are from the Red Scare.

Regarding the protections against illegal searches, I think all bets are off, even for US citizens.

Just be aware that windows has a bad habit of fucking up for Linux when you do. Which sounds like it shouldn’t be possible, right?

Windows can claim hardware resources that it doesn’t release properly, so your WiFi adapter doesn’t work in Linux, but works fine in Windows. Windows also (used to, at least) “correct” a boot partition, because, I presume, it sees something “unknown”. Oh, and the system clock might be off every time you switch between one and the other, because windows thinks it makes sense to write the current timezone value and not UTC.

Those kinds of things.
