It's already incredibly difficult, time-consuming, and expensive to secure an employment-based immigration path. The process takes between 1 to 2 years. In addition, the employer is required to attest (via labor certification) that there are no minimally qualified U.S. workers who can do the same job. The quotas create just decades-long backlogs, and make things even worse for immigrants.

The regulatory red tape for EB immigrant visas is incredible. I've read comments on HN and other forums saying that companies typically spent circa $40,000 to get an EB-2/EB-3 visa. In fact, Congress intentionally made it easier to get H-1B visas for precisely this reason: https://www.cato.org/blog/why-congress-rejected-h-1b-recruit...

You mean EB-2 and EB-3 (Employment Based green cards)?

E-3 is a US work visa for Australian citizens only, almost identical to H1-B but with a separate cap. It was a thank you to Australia from the Bush Administration for helping in the Iraq war.
