Unless you already work at the company you can't get a L1. And H1B1s are for Singaporean and Chileans only. Hardly a meaningful impact on the US immigration system. TN for Canadians & Mexicans are not visa and don't allow immigration intent. Getting an O1 visa is non-trivial (otherwise all the people who don't get H1B's would get one) The wait for getting a green card based on a job application is very long - practically no one goes that way. The US doesn't have a points-based skilled worker immigration system like many other countries do.
