There's also the L1B Company transfer, if you work for a company with offices in the US and they would be able to transfer you after a year. Bit of a gamble to find a company that would be willing to do this though, and you gotta work for probably years to find out.
H-1B, if you're not already in the US has a 100k fee attached to it. Though AFAIK that was a proclamation that expires at some point, but probably won't. So it's really not an option for 99% of people.
I'm not a lawyer, so definitely verify what i say, but i'm pretty sure these are also valid options.
Thank you.
