All true but probably also almost certainly has the long term effect of decreasing immigration more generally. Who wants to immigrate to a country where you can be randomly arrested and tortured? Would you?It's just another case where the Federal government is doing a rug pull: making people who are here legally suddenly undocumented. It's cruelty, and it's almost certainly because DHS can't actually find enough people to deport (surprising no one); so beyond being filled with cruel psychopaths, they're also just trying to juice the deportation numbers with these shenanigans.
We will feel the negative effects of this for the rest of our lives as it takes years and decades to build up trust and almost no time to destroy it.
All those smart doctors, scientists, engineers, etc. that the US used to poach from the rest of the world are going somewhere else now. If anyone thinks it’s a good idea to have fewer exceptional people coming to your country you’re in for a rude awakening.
