1. and 2. are anti-business. Just like raising the minimum wage, passing anti-business legislation is very, very difficult. 3. well, if there aren't any negatives, why is there currently a limit on the number of visas?
Sure, I'll agree to that.
>3. well, if there aren't any negatives, why is there currently a limit on the number of visas?
That's a good question, and I have no idea what the answer is. If anti-business legislation (like #1 and #2 here) is so hard to pass, then it seemingly shouldn't be that hard to pass pro-business legislation. Increasing the number of visas (or eliminating the limit) should, logically, be a pro-business position (lots more workers), while also being of interest to the left-leaning people who generally claim to be pro-immigration. So WTF is the problem? I don't know. The only people who should be opposed to such a move are 1) the outright anti-any-kind-of-immigration racists on the right (who aren't even a sizeable number, a large portion (most?) of the anti-immigration people are usually against illegal and/or low-skilled immigration), and 2) any firms that are profiting off the shortage of visas.
>directly contradicting the OP's implication that they are simple and easy.
I don't think the OP was under any illusion that passing such legislation would be simple and easy, due to the hyper-partisan nature of the current government. If the government weren't this way, passing reforms would be easy.
What's wrong with these ideas? 1. Criminal liability - this sounds a bit harsh, but some people are concerned about making sure "bad people" don't get in, so making the completion of proper background checks a hard requirement seems reasonable to allay their concerns. But then they might be concerned the background checks are bogus, so adding criminal liability helps with these concerns too. But granted, this is probably the most extreme part of that post.
2. Increasing labor costs - why is this bad for anyone except employers trying to use H1B as a way of keeping costs down? It's claimed to be a system for letting employers get skilled help where there's a labor shortage, so it's supposed to cost them more.
3. Easier to obtain PR: what the heck is wrong with this? If these immigrants are highly skilled, aren't causing any problems, and want to stay, why would you want to make it difficult for them to stay in your country and help your economy?
