Your claim could be shortened to:
>The ultimate uncertainty is that regardless of who you are and what you do, a country always has the right to kick you out...Nothing is guaranteed ultimately.
Which is what makes the actions of the government so disturbing. What made the USA so attractive (the rules, the decorum, the civility) is gone.
While there were a great many injustices, in general, it trended toward getting better over the years, until recently.
The craziest part is with globally declining total fertility rates, a country would be fortunate to have productive, younger people be banging on their door to be let in.

Depends on whether you think international law still exists and is followed - statelessness isn't allowed under that.
There's no single set of "international law" in the sense of national laws, state laws or local laws. There are only agreements and treaties between nations that are applied within those nations. As such, what "international law" applies depends on which nation you're in or from or if some nation's law enforcement have jurisdictional reach.
More to the point, nothing about this decision implies statelessness. Every visa applicant is a citizen of another foreign, non-American, nation. Being booted out doesn't make them stateless. They couldn't have applied for a visa if were stateless.
Note, I do agree that this suspension is unfair and a bad idea. But tossing out random accusations that imply that international law is being violated or causing people to become stateless doesn't help our case.
> whether you think international law still exists
Well that’s an easy one. It doesn’t. There are specific agreements, and I guess you could consider war crimes the primary example of an international court. But there is no and should be no international courts for immigration.
A country gets to set its own laws, end of story. The current happenings in the US are a direct pendulum swing from the previous administration. If people can’t accept that, it just shows how biased they are. Or how one-sided their information sources have been.
