Rights afforded by the US Constitution such as free speech, assembly, and due process extend to everyone in the country, not just citizens. But apparently, there is no right to be in the US. The state department (Marco Rubio) has the power to revoke any non-citizen’s permission. And that is exactly what they are doing right now to non-citizens who are legally in the US on visas for work, school, vacation, etc., if these people do or say something the Trump administration finds objectionable like attending a pro-Palestinian protest. They’ve revoked 500 student visas so far at dozens of universities. Google “revoke student visa”. And since there is no illegality needed, there is no due process necessary. These people are just sent home with no explanation given. In some cases they have no idea what they even did wrong. They can even be kicked out on mistaken identity because there is no due process. This has nothing to do with illegal immigration. These people are in the US legally, and have done nothing illegal. This policy is apparently designed to intimidate anyone who dissents, including citizens. If the Trump administration can find a legal loophole that allows them to harm their enemies they are using it. And if no loophole exists, they are trying it anyway (since Trump’s Supreme Court has already ruled that nothing he does can be a crime). See their actions against law firms and investigations into Miles Taylor (called Trump “unfit”) and Chris Krebs (called the 2020 election “secure”). All this is happening under your nose and you see it as purely focused on illegal immigration.
