> It is everyone holding or desiring a US visa that is worried

It's so far out of line of reason to believe that the US is going to basically end all - or any meaningful portion of - legal immigration, as to be nearly impossible to reply to. Where to start?

The US will switch, if anything, to a merit based system. Canada already uses just such a system. Nobody seems to be outraged about it, or proclaiming the end of Canada because of it. There's far too much emotion in this thread.

As someone that is look for jobs right now and talking with a lot of tech comapny in the US on the side, they just hold all tentative to get visas. O1 are still doable, but all H1B are on hold. If you are canadian, it is not a problem.

But all Europeans that would like to get visa are on hold right now. People that already have one are in limbo, worrying about how the coming ruling will affect them.

May I ask where you are from and what your field is?

I'm speaking in relation to Y Combinator and those who are looking to apply to come to the United Stats to start a company. The number of those people is an absolutely small number compared to the whole. Unless you have data proving otherwise?

I'm a visa holder and I'm not worried because worst case scenario I go back home to live with my family who loves me.

You haven't been reading the news very carefully. Worst case scenario is that you get sent to a 3rd party country, have your passport seized upon landing, and possibly end up in prison where your human rights are at risk.
