I would expect further H1B crackdowns coming. The $100k fee was just the start.
Despite the rhetoric the administration is very friendly to big business and will absolutely help them hire cheaply. Larry Ellison especially.
But no, they did virtually nothing. I would even be surprised if more than 100 companies paid the one time $100k fee at this point with all the loopholes that were included.
All the new regulations (carefully presented as crackdown) make it easier for large companies to hire immigrants in a more reliable way. All carefully choreographed by big tech.
The chances of a specific company being able to sponsor a specific employee through this year's lottery went by significantly (3-4x) compared to the last several years.
The better solution is just stop H1B lottery from next year.
Realistically, the H-1B visa program should be terminated all together.
The 100k fee basically does nothing to curb H1B cheap labor. It's a one-time fee, and when you realize that H1B's can't easily leave their job, it's a fee that easily pays for itself. H1B's are paid less for the same job (just google "are H1B's paid less"), and since they can't easily leave, the reduced turnover saves them money as well. If you think that an employee is likely to stay for 4 years, that's only 25k per year and the fact that they are paid about 15%-20% less than an American, the equation still easily comes out in favor of importing the cheap labor.
It was a move crafted to look like it was cracking down on abuse, but not actually cause any real pain to the companies abusing the system. Hence why all these mega corps are still filing for H1B's even while laying off their American citizen workers.
