Guess what the user meant is to make it easy for people on H1B to switch jobs which currently isn't. This makes so many employees to be at the jobs though low paying so as to keep their status in US.
You can, but if you have a green card application in process, you'll have to start all over again, unless it was in its final stage. This can easily put you back by several years.
The fundamental problem is that US simply doesn't have a well-designed skilled worker immigration track, the way e.g. Canada or Australia do. H1B fills that niche in practice, but it was clearly not designed for it, and so there are all these warts.
You realize that a person doesn't have to belong to the Illuminati as a precondition to lobby for special or opaque legislation, right? The only precondition intent needs is a conflict of interest.
Look at Intuit. A number of years back, California piloted a program that simplified filing tax returns for people opting to take the standard deduction. They would mail you a form that was prefilled so you could simply sign it and mail it back. Intuit lobbied to kill it and won. No laws were broken. They were simply acting in the interest of their shareholders.
The American Immigration Lawyers Association is one of many lobbying groups that represents 13,000 members. Many of these members help the 80,000 some H1B applicants through the process and can charge legal fees in the ballpark of $10,000 to do that. Assuming all 80,000 applicants spent $10,000 in legal fees, we're talking about ~$1bn market on top for that type of work alone. In the grand scheme of things, it's not a lot, but it's one component that can create a conflict of interest.
Let's assume the AILA is an upstanding group and all of the lobbyists they hire are ethical boy scouts. They would never influence our legislators to intentionally complicate laws to serve their members. Instead, they would recognize that it's in our nation's best interest that our immigration systems are robust, thorough and comprehensive. They'd also emphasize that their members provide a critical service to sherpa honest immigrants through this thoroughly comprehensive system.
You don't need to be behind a ridiculous conspiracy to influence legislation to serve your best interests. These days, you're way better off being transparent and operating under an ethical framework.
